Healthy eating tip 1: Set yourself up for success

To set yourself up for success, think about planning a healthy diet as a number of small, manageable steps rather than one big drastic change. If you approach the changes gradually and with commitment, you will have a healthy diet sooner than you think.

• Simplify. Instead of being overly concerned with counting calories or measuring portion sizes, think of your diet in terms of color, variety, and freshness. This way it should be easier to make healthy choices. Focus on finding foods you love and easy recipesthat incorporate a few fresh ingredients. Gradually, your diet will become healthier and more delicious.
• Start slow and make changes to your eating habits over time.Trying to make your diet healthy overnight isn’t realistic or smart. Changing everything at once usually leads to cheating or giving up on your new eating plan. Make small steps, like adding a salad (full of different color vegetables) to your diet once a day or switching from butter to olive oil when cooking.  As your small changes become habit, you can continue to add more healthy choices to your diet.
• Every change you make to improve your diet matters. You don’t have to be perfect and you don’t have to completely eliminate foods you enjoy to have a healthy diet. The long term goal is to feel good, have more energy, and reduce the risk of cancer and disease. Don’t let your missteps derail you—every healthy food choice you make counts.

Healthy eating tip 2: Moderation is key 

People often think of healthy eating as an all or nothing proposition, but a key foundation for any healthy diet is moderation.  Despite what certain fad diets would have you believe, we all need a balance of carbohydrates, protein, fat, fiber, vitamins, and minerals to sustain a healthy body.

• Try not to think of certain foods as “off-limits.”When you ban certain foods or food groups, it is natural to want those foods more, and then feel like a failure if you give in to temptation. If you are drawn towards sweet, salty, or unhealthy foods, start by reducing portion sizes and not eating them as often. Later you may find yourself craving them less or thinking of them as only occasional indulgences.
• Think smaller portions. Serving sizes have ballooned recently, particularly in restaurants. When dining out, choose a starter instead of an entrée, split a dish with a friend, and don’t order supersized anything. At home, use smaller plates, think about serving sizes in realistic terms, and start small.  Visual cues can help with portion sizes—your serving of meat, fish, or chicken should be the size of a deck of cards. A teaspoon of oil or salad dressing is about the size of a matchbook and your slice of bread should be the size of a CD case.

Healthy eating tip 3: It’s not just what you eat, it’s how you eat

 

Healthy eating is about more than the food on your plate—it is also about how you think about food. Healthy eating habits can be learned and it is important to slow down and think about food as nourishment rather than just something to gulp down in between meetings or on the way to pick up the kids.

• Eat with others whenever possible.Eating with other people has numerous social and emotional benefits—particularly for children—and allows you to model healthy eating habits. Eating in front of the TV or computer often leads to mindless overeating.
• Take time to chew your food and enjoy mealtimes. Chew your food slowly, savoring every bite. We tend to rush though our meals, forgetting to actually taste the flavors and feel the textures of our food. Reconnect with the joy of eating.
• Listen to your body. Ask yourself if you are really hungry, or have a glass of water to see if you are thirsty instead of hungry. During a meal, stop eating before you feel full. It actually takes a few minutes for your brain to tell your body that it has had enough food, so eat slowly.
• Eat breakfast, and eat smaller meals throughout the day. A healthy breakfast can jumpstart your metabolism, and eating small, healthy meals throughout the day (rather than the standard three large meals) keeps your energy up and your metabolism going.

Healthy eating tip 4: Fill up on colorful fruits and vegetables 

Fruits and vegetables are the foundation of a healthy diet. They are low in calories and nutrient dense, which means they are packed with vitamins, minerals, antioxidants, and fiber.

Try to eat a rainbow of fruits and vegetables every day and with every meal—the brighter the better. Colorful, deeply colored fruits and vegetables contain higher concentrations of vitamins, minerals, and antioxidants—and different colors provide different benefits, so eat a variety. Aim for a minimum of five portions each day.

Some great choices include:

• Greens. Branch out beyond bright and dark green lettuce. Kale, mustard greens, broccoli, and Chinese cabbage are just a few of the options—all packed with calcium, magnesium, iron, potassium, zinc, and vitamins A, C, E, and K.
• Sweet vegetables. Naturally sweet vegetables—such as corn, carrots, beets, sweet potatoes, yams, onions, and squash—add healthy sweetness to your meals and reduce your cravings for other sweets.
• Fruit. Fruit is a tasty, satisfying way to fill up on fiber, vitamins, and antioxidants. Berries are cancer-fighting, apples provide fiber, oranges and mangos offer vitamin C, and so on.

The importance of getting vitamins from food—not pills

The antioxidants and other nutrients in fruits and vegetables help protect against certain types of cancer and other diseases. And while advertisements abound for supplements promising to deliver the nutritional benefits of fruits and vegetables in pill or powder form, research suggests that it’s just not the same.

A daily regimen of nutritional supplements is not going to have the same impact of eating right. That’s because the benefits of fruits and vegetables don’t come from a single vitamin or an isolated antioxidant.

The health benefits of fruits and vegetables come from numerous vitamins, minerals, and phytochemicals working together synergistically. They can’t be broken down into the sum of their parts or replicated in pill form.

Healthy eating tip 5: Eat more healthy carbs and whole grains

Choose healthy carbohydrates and fiber sources, especially whole grains, for long lasting energy. In addition to being delicious and satisfying, whole grains are rich in phytochemicals and antioxidants, which help to protect against coronary heart disease, certain cancers, and diabetes. Studies have shown people who eat more whole grains tend to have a healthier heart.

A quick definition of healthy carbs and unhealthy carbs

Healthy carbs (sometimes known as good carbs) include whole grains, beans, fruits, and vegetables. Healthy carbs are digested slowly, helping you feel full longer and keeping blood sugar and insulin levels stable.

Unhealthy carbs (or bad carbs) are foods such as white flour, refined sugar, and white rice that have been stripped of all bran, fiber, and nutrients. Unhealthy carbs digest quickly and cause spikes in blood sugar levels and energy.

Tips for eating more healthy carbs

 

• Include a variety of whole grains in your healthy diet, including whole wheat, brown rice, millet, quinoa, and barley. Experiment with different grains to find your favorites.
• Make sure you’re really getting whole grains. Be aware that the words stone-ground, multi-grain, 100% wheat, or bran can be deceptive. Look for the words “whole grain” or “100% whole wheat” at the beginning of the ingredient list. In the U.S., Canada, and some other countries, check for the Whole Grain Stamps that distinguish between partial whole grain and 100% whole grain.
• Try mixing grains as a first step to switching to whole grains. If whole grains like brown rice and whole wheat pasta don’t sound good at first, start by mixing what you normally use with the whole grains. You can gradually increase the whole grain to 100%.

Avoid: Refined foods such as breads, pastas, and breakfast cereals that are not whole grain.

Healthy eating tip 6: Enjoy healthy fats & avoid unhealthy fats

Good sources of healthy fat are needed to nourish your brain, heart, and cells, as well as your hair, skin, and nails.  Foods rich in certain omega-3 fats called EPA and DHA are particularly important and can reduce cardiovascular disease, improve your mood, and help prevent dementia.

Add to your healthy diet:

• Monounsaturated fats,from plant oils like canola oil, peanut oil, and olive oil, as well as avocados, nuts (like almonds, hazelnuts, and pecans), and seeds (such as pumpkin, sesame).
• Polyunsaturated fats, including Omega-3 and Omega-6 fatty acids, found in fatty fish such as salmon, herring, mackerel, anchovies, sardines, and some cold water fish oil supplements. Other sources of polyunsaturated fats are unheated sunflower, corn, soybean, flaxseed oils, and walnuts.

Reduce or eliminate from your diet:

• Saturated fats, found primarily in animal sources including red meat and whole milk dairy products.
• Trans fats, found in vegetable shortenings, some margarines, crackers, candies, cookies, snack foods, fried foods, baked goods, and other processed foods made with partially hydrogenated vegetable oils.

Healthy eating tip 7: Put protein in perspective

Protein gives us the energy to get up and go—and keep going. Protein in food is broken down into the 20 amino acids that are the body’s basic building blocks for growth and energy, and essential for maintaining cells, tissues, and organs. A lack of protein in our diet can slow growth, reduce muscle mass, lower immunity, and weaken the heart and respiratory system. Protein is particularly important for children, whose bodies are growing and changing daily.

Here are some guidelines for including protein in your healthy diet:

Try different types of protein. Whether or not you are a vegetarian, trying different protein sources—such as beans, nuts, seeds, peas, tofu, and soy products—will open up new options for healthy mealtimes.

• Beans:  Black beans, navy beans, garbanzos, and lentils are good options.
• Nuts: Almonds, walnuts, pistachios, and pecans are great choices.
• Soy products: Try tofu, soy milk, tempeh, and veggie burgers for a change.
• Avoid salted or sugary nuts and refried beans.

Downsize your portions of protein. Many people in the West eat too much protein. Try to move away from protein being the center of your meal. Focus on equal servings of protein, whole grains, and vegetables.

Focus on quality sources of protein, like fresh fish, chicken or turkey, tofu, eggs, beans, or nuts. When you are having meat, chicken, or turkey, buy meat that is free of hormones and antibiotics.

Healthy eating tip 8: Add calcium for strong bones

Calcium is one of the key nutrients that your body needs in order to stay strong and healthy. It is an essential building block for lifelong bone health in both men and women, as well as many other important functions.

You and your bones will benefit from eating plenty of calcium-rich foods, limiting foods that deplete your body’s calcium stores, and getting your daily dose of magnesium and vitamins D and K—nutrients that help calcium do its job.

Recommended calcium levels are 1000 mg per day, 1200 mg if you are over 50 years old. Take a vitamin D and calcium supplement if you don’t get enough of these nutrients from your diet.

Good sources of calcium include:

• Dairy: Dairy products are rich in calcium in a form that is easily digested and absorbed by the body. Sources include milk, yogurt, and cheese.
• Vegetables and greens: Many vegetables, especially leafy green ones, are rich sources of calcium. Try turnip greens, mustard greens, collard greens, kale, romaine lettuce, celery, broccoli, fennel, cabbage, summer squash, green beans, Brussels sprouts, asparagus, and crimini mushrooms.
• Beans: For another rich source of calcium, try black beans, pinto beans, kidney beans, white beans, black-eyed peas, or baked beans.

Healthy eating tip 9: Limit sugar and salt

If you succeed in planning your diet around fiber-rich fruits, vegetables, whole grains, lean protein, and good fats, you may find yourself naturally cutting back on foods that can get in the way of your healthy diet—sugar and salt.

Sugar

Sugar causes energy ups and downs and can add to health and weight problems. Unfortunately, reducing the amount of candy, cakes, and desserts we eat is only part of the solution. Often you may not even be aware of the amount of sugar you’re consuming each day. Large amounts of added sugar can be hidden in foods such as bread, canned soups and vegetables, pasta sauce, margarine, instant mashed potatoes, frozen dinners, fast food, soy sauce, and ketchup. Here are some tips:

• Avoid sugary drinks. One 12-oz soda has about 10 teaspoons of sugar in it, more than the daily recommended limit! Try sparkling water with lemon or a splash of fruit juice.
• Eat naturally sweet food such as fruit, peppers, or natural peanut butter to satisfy your sweet tooth.

Salt

Most of us consume too much salt in our diets. Eating too much salt can cause high blood pressure and lead to other health problems. Try to limit sodium intake to 1,500 to 2,300 mg per day, the equivalent of one teaspoon of salt.

• Avoid processed or pre-packaged foods. Processed foods like canned soups or frozen dinners contain hidden sodium that quickly surpasses the recommended limit.
• Be careful when eating out. Most restaurant and fast food meals are loaded with sodium.
• Opt for fresh or frozen vegetables instead of canned vegetables.
• Cut back on salty snackssuch as potato chips, nuts, and pretzels.
• Choose low-salt or reduced-sodium products.
• Try slowly reducing the salt in your diet to give your taste buds time to adjust.

Intermittent fasting, whey protein, and weight loss?

For those of us who’re looking to lose weight, a recent study published in the British Journal of Nutrition might offer some hope.  Losing weight is never easy as it requires a lifelong commitment to changes in dietary habits as well as activity level.

Years ago, I read a book by Greg LeMond, the former three-time Tour de France winner.  I loosely recall him mentioning something about you can’t lose weight by sitting on your couch eating hot-fudge Sundaes.

Conventional wisdom being the usual edict of calories in and calories out holds true for the most part.  However, some recent research suggest that intermittent fasting might offer an unconventional weight loss strategy.

Though I’m not going to bother citing a reference here, the Body for Life book by Bill Phillips was probably the first mention of the often promulgated advice of 6 small meals per day.  The purported benefit of this meal plan was that it would prevent your metabolism from slowing down while also keeping you in an anabolic state for those who engage in resistance training.

For most people, if you’ve ever tried the eat 6 small meals per day method, you probably find that you end up getting used to never feeling hungry.  After awhile, chances are you lose discipline over portion control and the next thing you know it leads to simply eating too much and too often.

Not wanting to stop at my intuitive feelings over the meal frequency myth, I found a very recent review study that has debunked this myth.  A review published in the Journal of Nutritionmade the following conclusion:

Taken together, these findings suggest that increased eating frequency (>3 eating occasions/d) has minimal, if any, impact on appetite control and food intake, whereas reduced eating frequency(<3 eating occasions/d) negatively effects appetite control.

Okay, so this review only addresses the effect of meal frequency on appetite control and food intake, what about weight loss?  From a study published in the British Journal of Nutrition, they found that meal frequency had NO benefit on promoting weight loss in obesity subjects on a calories restricted diet:

We conclude that increasing MF (meal frequency) does not promote greater body weight loss under the conditions described in the present study.

Intermittent Fasting?

Contrary to this diet regime, a recent study published in the International Journal of Obesitysuggest that intermittent fasting can not only be effective for lowering insulin resistance, blood pressure, and cholesterol, but also promotes weight loss.  This and other studies in this area contradict the fear that your metabolism will ‘slow down’ causing you to gain weight if you don’t eat 6 small meals per day.  In fact, intermittent fasting was more effective than calorie restriction at reducing insulin resistance in this particular study.

Okay, so now we’ve established that eating frequently won’t suppress your appetite , reduce your energy intake, or help you lose more weight.  If you want to improve your insulin resistance and lose weight, intermittent fasting is an option worth considering (in consultation with a health professional).  What if you just want to suppress your appetite to help you lose weight, is there anything that works?

Effects of whey protein on suppressing appetite:

Speaking of losing weight…  Another recent study, published in the British Journal of Nutrition, found that there’s a dose-response effect for drinking a whey protein beverage 90 minutes prior to eating.  Participants in this study, however, were already within a healthy weight range (BMI 19-25, both men and women).

In this study, the participants drank a 400 ml  [400 calorie] beverage 90 minutes prior to eating an ad libitum test meal.  In addition to a placebo beverage containing flavored water, they were also randomized to a 400 calorie beverage containing 12.5, 25, or 50% of the calories from whey protein.

Energy intake after preload:

• placebo – 987 Calories
• 12.5% protein beverage – 841 Calories
• 25% protein beverage – 808 Calories
• 50% protein beverage – 681 Calories

From this data, consuming a whey protein beverage prior to large meals, particularly dinner, may be beneficial for those looking to reduce their appetite and lose weight.

6 Great Reasons Why We Need to Exercise

I had never thought of sharing on “why exercise” and always assumed that we all believed and agreed that it was an essential part of everyone’s lifestyle regardless of whether one had the time or discipline to do it, until about two years ago I gradually pulled myself out from a sedentary lifestyle and I established a workout regimen in the morning and started to read more about the different types of workout such as aerobic training, resistance exercise and weight bearing activities. I reckon that exercising may be very often emphasized by all, but sometimes, its benefits may not be so clear and obvious to everyone.

1. Helps Strengthen Your Heart

Aerobic exercises benefit the circulation of your blood through your heart and blood vessels, that is, your cardiovascular system. They make our heart work harder, pump more blood, and reduce the risk of developing heart disease. With each beat of your heart, a surge of blood is pumped into your body’s intricate web of blood vessels. The pressure exerted on your artery walls as blood passes through helps keep the blood flowing smoothly (what you know as ‘blood pressure’). A build-up of plaques in your arteries, caused by cholesterol in your bloodstream can affect your blood flow and cause serious damage to your cardiovascular system.

A workout on a regular basis benefits your heart because it helps lower the build-up of plaques in arteries by increasing the concentration of high-density lipoprotein (HDL) cholesterol (the “good” cholesterol) and decreasing the concentration of low-density lipoprotein (LDL) cholesterol (the “bad” cholesterol) in your blood, while keeping the blood pressure at the optimal level.  As a result, your heart is able to do a better job in delivering oxygen to all parts of your body. Blood travels more efficiently, bringing much-needed oxygen from your lungs and nutrients to the rest of the body. That’s why people generally feel more refreshed and energetic after exercising.

Want to consider some aerobic activities? Try swimming, basketball, rope skipping, jogging (or brisk walking), in-line skating, soccer, or biking.

2. Maintains Strong Bones and Muscles

I am sure most of us have tried doing push-ups, weight lifting in some form, or repeatedly used your muscles to counter some kind of resistance. These are called resistance exercises which the experts believe could strengthen our muscles; preserve bone mass, increase bone density. Regular resistance training can help prevent the bone-weakening disease, osteoporosis.

Walking and jogging are also important activities that bear your body’s weight and help build strong muscles and bones. Other resistance workout include pull-ups, running, kettlebell training, and rowing.

3. Helps Manage Your Weight

This benefit is well-known to all who are weight conscious or trying to lose the extra pounds.

Your body needs a certain amount of calories every day just to function. If you eat more calories than your body needs, it may be stored as excess fat. For instance, if you have an excess of 10kg fat, and each gram has some 9 calories, then you have 90000 calories for your body to use!

Exercising helps you achieve or maintain a healthy weight by stoking our metabolism, utilizing and burning the extra calories. And if you exercise, your body works harder and needs more fuel. Even after you stop exercising, your body continues to burn calories at a modestly increased rate for a few hours. The more intensely you workout, the more calories you burn. By burning more calories than you take in, you can reduce body fat, giving you a healthier body composition. Losing body fat can make you look and feel better and can reduce your risk of obesity.

4. Induces Quality Sleep at Night

Many people who have problems sleeping find doing moderate exercise at least three hours before bedtime help in relaxing and sleeping better at night.  The recent Hibernation Diet Theory teaches that regular exercise could activate production of recovery hormones during sleep, increases our body’s metabolic rate and promotes fat-burning. It makes a powerful association between poor sleep and obesity, a disease that has been rising dramatically in developed countries and has reached epidemic levels in the United States. While most of us would associate poor weight control with aging, low metabolism rate, and poor eating habits, many other research studies have also reported and pointed to the relationship between insufficient sleep and weight gain.

So start today, get a good night’s sleep, aim for eight hours a night if you can, and add resistance workouts will speed up your weight loss and the body will worker harder at night.

5. Puts You in a Better Mood

We all know that it definitely feels good to have a strong, flexible body that can do all the activities you enjoy and be able to move your arms and legs freely without feeling tightness or pain. But you may not know that exercising can actually put you in a better mood.

Exercise combats depression by activating the neurotransmitters, which are basically chemicals used by our nerve cells to communicate with one another and often associated with avoiding depression. The balance of these neurotransmitters, namely serotonin and norepinephrine plays a role in how we respond to daily events. When experiencing stress, our level of serotonin, norepinephrine or both may be out of equilibrium. Workouts may help synchronize those brain chemicals.

Exercising also stimulates the production of endorphins, another type of neurotransmitters that produce feelings of well-being, provide for “natural” pain relief, and help you relax.

Sounds good? If you just had a tough day at work and need to let off some steam, go for a workout or a brisk 30-minute walk to calm yourself down.

Well, if you have not any form of physical training for a long while and find it a pain to do so, I suggest that you start doing it 2 times a week and slowly increasing to 3 and then 5 times or more a week. You can do 10 or 15 minutes bouts of workout each time to make up a 30 minutes session a day.

6. Inspires Your Lymphatic System to Work Better

Now, this is a relatively new knowledge for me and thus has become my latest edition to this page (which was previously known as “5 Great Reasons Why We Need to Exercise”). While the above reasons have given us enough incentive to workout, there is yet another reason which I never knew before, the extremely essential lymphatic system. It is a vital network of vessels and nodes responsible for regulating fluids, distributing proteins and filtering out poisons in the fluid between the cells. It is a protector and a defence system against infection, viruses, bacteria, fungi, and disease. The three most important methods of lymphatic circulation are external massage, muscle expansion and contraction, and intense exercise. This means the more you move, the livelier it becomes. When the lymph is not overloaded, our health is maintained with nature’s own detox design. But if the lymph is running sluggish and there is too much waste, a blockage in the lymphatic system happens, leading to symptoms like chronic fatigue, water retention, eczema, allergies,  arthritis, and infections.

Importance of Balance and Stability to Mastery of Sport Skills

It could be said that the world’s best athletes are always in control. It can be defined as mental control, as their recognition of specific situations within the game and how they can appropriately respond. Or as emotional control, their ability to ignore the things that don’t matter and focus on the things that do make a difference in the game’s outcome. But, certainly, the ability to control one’s physical self is a major issue for athletes. They must control their sports skills and execute them properly, despite numerous obstacles that are very physical in nature. An obstacle could be a rushing defensive lineman, in football; a tall, long-armed center, in basketball; or a quick-moving goalkeeper, in soccer. In all cases, a high level of physical control—more specifically, balance and stability—is required.

Balance and stability: The words may seem interchangeable, but they are not. The words are closely linked, of course, but they aren’t a two-way street, because it is possible for an athlete to have one but not the other.

Balance is the ability to neutralize forces that would disturb equilibrium. Most healthy people have balance to one degree or another. Simply watching a young toddler take those first steps is evidence of this. Further evidence of balance can be seen in a variety of movements: from someone simply standing on one leg, to an intricate, dynamic movement during execution of a specific sports skill. The topic of balance gets even more interesting when one throws moving, living, breathing obstacles in an athlete’s path. For instance, the football running back must demonstrate great balance as he ricochets off defensive linemen. Or notice the balance of the basketball point guard as she weaves around players on her way to the basket.

Balance comes in all levels of difficulty. The line that separates superiority in a specific sports skill is the concept of stability. Stability is measured in the level at which one can retain one’s balance while experiencing factors that disturb balance. In short, stability is described by the answer to the question, “How balanced are you?” Skilled athletes are able to employ certain tactics to increase their stability under oncoming forces, practically bracing themselves to be immovable.

The amazing athletic highlights seen on television are usually a result of dynamic stability, or stability on the move. The difference between balance and stability can be seen easily on the football field. A punter has great balance as he receives the snap and punts the ball 50–60 yd, elevating high on one leg and landing effortlessly on that same leg. The punter’s lack of stability is seen, however, when a defensive back comes flying into him while he is in the air or standing one-legged. The sacrifice of stability in the practice of balance usually results in a flattened punter. On the other hand, a 290-lb offensive lineman, his backside dropped into an athletic stance, can take on the maximal pushing of 400-lb defensive lineman and not fall down, because he has great balance and stability (remember, “How balanced are you?”).

Two other sports positions that thrive from a combination of balance and stability are the baseball catcher and the basketball post player. Both positions rely on some degree of balance and some degree of stability. The baseball catcher’s balance and stability, however, are an absolute necessity for the position, and the best basketball post players, too, understand the value of balance, stability, and leverage.

The baseball catcher, first, ideally has such physical traits as quick feet and hands, good arm strength, and good balance and stability. The catcher will spend much of the time on the field in the crouch position. The catcher’s weight will be on the heels, and the knees will be bent to place the upper leg below parallel to the ground. In this position, the rear end is near the back of the heels. The catcher’s back should not be curved; the shoulder blades should furthermore be pinched back. The catcher’s head should be held high and the gloved hand should be held out. This crouch position (and the ability to catch pitches) relies heavily on the catcher’s mastery of balance and linear stability.

Balance has been defined as ability to neutralize forces that might disturb equilibrium, while stability has been defined as the level of challenge at which one can still balance. Linear stability is putting up resistance against being moved in a given direction. The catcher’s linear stability is challenged by the action of stopping an 80- or 90-mph pitch. Linear stability is directly related to the mass of the object that applies force (here, the baseball pitch) and the object that resists the force (here, the catcher). Due to the “massive” difference between force mass and resistance mass, for catchers, linear stability is an easy battle.

Two of the most important skills a catcher performs are blocking a bad pitch and throwing out a runner attempting to steal a base. Blocking bad pitches many times involves leaving the crouch position to throw oneself in front of the pitch and keep it from passing behind one. The nature of the crouch position reflects three important principles of stability:

1. A broader base of support increases stability. (A catcher’s stance places feet more than hip-width apart.)
2. Centralizing the line of gravity inside the support base increases stability. (A straight back and head held upright centralize the line of gravity.)
3. A lower center of gravity increases stability. (Crouching’s deep knee bend lowers the center of gravity.)

Because of these three products of the crouch position, a catcher can quickly maneuver the entire body (most importantly, the line of gravity) in front of a speeding pitch moving well outside of the strike zone.

Many times, stability depends on an athlete’s ability to put the line of gravity towards an oncoming force. The movement temporarily unbalances the athlete, but then the impact of the force re-balances him or her. But for the catcher blocking the bad pitch, this is not the case. Despite its velocity and momentum, the baseball has very little mass. This means that the catcher must first quickly throw his line of gravity in front of the ball, then also quickly re-balance, exploiting the advantage of the baseball’s force. It is for this reason the catcher often blocks a pitch by dropping to the knees. Dropping to the knees lowers the center of gravity even further, providing the catcher with greater stability.

The skill employed when a catcher challenges a runner’s attempt to steal is, in some ways, a reversal of balance and stability principles. As when blocking bad pitches, the catcher must position the line of gravity in front of the force to throw out the runner. In the skill of rising and then throwing to the base, the catcher applies force rather than resists it. As the catcher rises, the line of gravity must remain centered to prevent falling over before the ball can be thrown. As the catcher draws back to throw, weight must be shifted onto the back foot, to the rear of the base of support. In some extreme examples, the “thrower” actually shifts the line of gravity temporarily outside the base of support. As the throwing motion begins, the line of gravity shifts from the rear of the support base, through the center and front, ending up in front of the support base.

As for the basketball post player, things have changed in the past two decades. What was once a position for massive, slow-footed players playing 5– 10 ft from the basket is now more commonly given to players who, although still very tall and long, have lesser mass in exchange for better foot speed and more perimeter-oriented skills. The old-fashioned post player may have become an endangered species, but the importance of balance and stability for a large post player cannot be overstated.

Basketball post players are subject to several particularly important principles when attempting to enhance stability in order to deter a bigger, stronger player (or when themselves presenting the bigger, stronger player attempting to dominate). The first principle is the player’s own mass, which should be taken advantage of. Athletes automatically have greater stability when they have greater mass. Not only does Shaquille O’Neal have great footwork, he also has what few others in the NBA have: enormous mass. At one time early in his career, it was speculated that O’Neal weighed 380 pounds, less than 10% representing body fat. Imagine how stable a mass like that is! At times, however, athletes of enormous mass can be put at a disadvantage when their momentum is used against them. The more mass one has, the harder it is to get going and the harder it is to stop or change direction. The mad rush of a 400-lb sumo wrestler is fairly easily used against him if the opponent sidesteps and adds to the momentum with a grab or push propelling the first wrestler on down his initial course. Basketball players of such size have a great advantage. The nature of their position does not require large amounts of momentum, and since they typically operate within 5–10 ft of the basket, their mass can rarely be used against them.

The second principle is the value of a wide base when posting up or blocking out. Again, stability can be increased by widening the base of support. Many post players miss out on prime positioning because they simply do not have a wide enough base. This is especially true if a player with less mass is attempting to gain an advantage on a player with more mass. In short, get wide. The third principle is the value of lowering the center of gravity. This happens to some extent whenever the base is widened; but that is not enough. Post players must learn to play with a wide base and bent knees. A player with a mass advantage will become dominant when he or she masters the value of bending the knees and lowering that massive center of gravity. In short, get low.

The fourth principle involves the need to extend the base of support in the direction of an oncoming force. Rotary stability has taught us that shifting the line of gravity in the direction of that force can help us stabilize and defend against the applied force. However, the defending post player must not shift the line of gravity too close to the support base’s front perimeter. When that happens, the player moves out of the base of stability, becoming unbalanced.

In sum, the application of principles of balance and stability when performing specified sports skills is necessary to success. Many coaches would be wise to spend more time studying sport mechanics like balance and stability in order to improve the performance of their players.
