Plyometrics: Controlled Impact/Maximum Power


The Eastern Europeans first used plyometrics in the 1970s to develop greater strength and power in their Olympic athletes. They based their programs on scientific evidence that stretching muscles prior to contracting them recruits the ''myotactic'' or stretch reflex of muscle to enhance the power of contraction. This prestretching of muscles occurs when you perform jumps one after the other.

One study found that participants in a well-designed program of stretching, plyometric training and weight training reduced their landing forces from a jump by 20 percent, and increased their hamstrings strength by 44 percent. Both of these factors contribute to reducing an individual's potential risk of injury.

A safe and effective plyometric program stresses quality, not quantity of jumps. Safe landing techniques, such as landing from toe to heel from a vertical jump, and using the entire foot as a rocker to dissipate landing forces over a greater surface area, also are important to reduce impact forces. In addition, visualization cues, such as picturing yourself landing ''light as a feather'' and ''recoiling like a spring'' after impact promotes low-impact landings.

If you are considering plyometrics, proceed with caution. Carefully considering the type of jumps selected for the program, enlisting a coach or trainer for supervision, and gradually increasing to more difficult exercises can make a plyometric program both safe and effective.

Learning from Losers

For the past dozen years, researchers Rena Wing, Ph.D., and James Hill, Ph.D., tracked about 6,000 people in their National Weight Control Registry: Participants lost at least 30 pounds and maintained that for at least a year. (The average is 70 pounds off and for six years.) The successful losers didn't turn to wacky eating plans, fad diets, or extreme measures like gastric-bypass surgery. Instead, what worked was common sense-they modified their diet and increased their physical activity to change their caloric balance.

Most people who have lost weight (and kept it off) adopted these five habits. It'll be your loss if you adopt them, too:

Keep Up the Carbs Most successful losers get about 49 percent or more of the calories from carbs, about 29 percent from fat, and the remainder from protein. The key is selecting the foods rich in fiber which proviies a sense of fullness. Research shows that a diet that includes 34 or more grams of fiber daily actually drops the number of calories your body takes up from your food. Over a year, this could equal a 10-pound weight loss.

Take Good Notes Most dieters typically stop bothering to write down what they eat after a few months of weight loss. But many kept a food diary for years, taking measurements and noting precise portions and calorie counts. This allows them to respond quickly to changes in their eating patterns.

Become a Morning Person In one study, 78 percent of NWCR participants reported eating breakfast every day-a habit that may help curb appetite later in the day. Research shows that breakfast eaters, especially those who start the day with cereals (a natural for fiber), have a lower body mass index than those who skip the morning meal. Plus, protein often appears in breakfast foods in its proper proportion for sating appetite.

Weigh In Routinely stepping on the scale and checking body weight is another key way to stay on the losing side. To keep that routine from becoming obsessive, don't weigh yourself more than once a week. (You might want to forgo the scale at home to resist temptation.) There are normal weight fluctuations throughout the day. To keep an accurate gauge, weigh yourself on the same day of the week, at the same time.

Keep Moving The average person in the registry is burning about 2,800 calories a week in activity." Last year, the USDA established 60 to 90 minutes as the recommended daily physical activity for those trying to maintain weight loss. Research shows that people who exercise daily on average weigh less than sedentary folks but eat more.

Behind the Neck Lat Pulldowns: DON'T DO THEM!! Here's Why.

We see people doing these all the time, often they have heard that the exercise is not recommended but continue to do them anyhow. Who recommends against these? NFL trainers, the Mayo Clinic. I'll give you a link to the sources and summarize below.

Over time, performing pull downs behind the neck weakens the rotator cuff - you probably won't feel this immediately but weeks, months or years later you'll pay a high price, According to NFL trainer Dan Riley, this exercise puts the shoulder and specifically the rotator cuff muscles in a weak and vulnerable position. The shoulders are forced to rotate externally and the shoulder blades move to the center of the body, causing the external rotator cuff muscles to pull against the tight internal rotator muscles. If you work at a desk all day long your shoulders are internally rotated and the internal rotators are TIGHT! They simply are not made to bear this weight and stress. Over time they become weaker or fibrous, injury follows, and you can kiss your rotator cuff muscles goodbye. There is also risk to the cervical spine from bringing the head forward. Plus, this exercise is not even as effective in targeting the lats as pulldowns in front of the body.

Behind the neck shoulder presses and upright rows are two other exercises that should be avoided for the same reasons. When performing pulldowns and presses, keep the weight in front of the body.

So, You Want To Spot Reduce? Here's How...

Besides launching millions of sit-ups, leg lifts and torso twists, the desire for a toned and taut physique has sold a long line of exercise devices of dubious worth. Countless inventions, such as vibrating belts and ''gut-busting'' contraptions, have claimed to miraculously tighten and tone our trouble spots.

But the miracles we were expecting never materialized, and our ''spots'' remained ''unreduced.'' What's wrong with spot reduction?

Where did we go wrong? In our efforts to tone our bodies we neglected the most important factor: fat. Exercises such as crunches or leg lifts improve the tone and endurance of the muscles, but they don't burn fat. When we do exercises that elevate the heart rate, such as bicycling, walking or aerobic dance, the body will draw upon its fat stores for energy.

Alternative solutions Eating a low-fat diet and following an exercise program that combines aerobic activity and strength training is the key to changing the shape of your body.

In addition to burning calories through aerobic activity, strength training will increase the amount of muscle, which burns even more calories. But many people shun the idea of intensive exercise, scared off by the idea of five-mile runs, barbells or aerobic classes.

Thankfully, any aerobic activity that elevates your heart rate can help you burn fat and take off unwanted pounds. Many experts recommend doing at least three sessions of 20 minutes of aerobic activity per week. Ideally, for long-term weight control, you should engage in at least four sessions per week, for 45 minutes each time.

Successful Weight Control: It's not just cutting calories

According to ACE, eating less, or cutting back on fat in your diet, won't keep the weight off. What you really need to do is strike a good balance between the number of calories you consume and the number you burn. And the only way to do that is to exercise. By exercising, you can lose weight while you eat more calories than if you simply went on a diet. Regular physical activity is much more effective at keeping the weight off in the long run than any diet.


One choice is aerobic exercise You'veprobably heard about exercise programs that turn your body into a ''fat-burning machine.'' An aerobic programcan help you lose weight more easily because it can stimulate your body and make it burn calories. Low-impact aerobics like walking, step aerobics and dance are your best bets. Some good no-impact aerobic activities you can benefit from include swimming, bicycling and rowing. Begin with as littleas 15 minutes of low-impact aerobics three times aweek. Gradually increase to 30 minutes of moderate aerobic activity four times a week.

Strength training = weight management Your muscles burn calories during physical activity. What you may not know is your muscles also burncalories when your body is at rest. Increase your muscle mass, and you'll be increasing your body's capacity to burn calories both during activity and at rest.

Success means good eating and good exercise Follow a moderate low-fat diet and an exerciseprogram that combines aerobic activity and strengthtraining. That's the key to losing weight - and keeping it off. And remember, you can't lose weight overnight. Set a realistic weight-loss goal for yourself - like one to two pounds a week - eat healthy, get going on a program of regular physical activity, and you'll be delighted by what you accomplish.

The NASM OPT Model: Periodized Training and Progression

Until now, most training programs have been based mainly on the experiences and goals of body builders, coaches and athletes. There's aproliferation of scientifically unsupported trainingprograms that are not designed to meet the needs of an increasingly deconditioned and injury-prone society. NASM’s Optimum Performance Training (OPT) method is a comprehensive training program based on scientific research that provides results specific to individual needs and goals.

Assessment At the center of the OPT method is the assessment. This fitness and performance evaluation assesses an individual’s strengths and weaknesses in the areas of posture, movement, strength, flexibility and athletic performance. Before embarking on a training program, it is essential to address any existing imbalances to ensure success.

Optimum Performance Training: Individualized Program Design The OPT method provides a system for exercise selection based on the client’s needs, abilities and goals. The endless choices of exercises and the unique progressions keep every program fun, dynamic and, most importantly, successful. The Pyramid of Success represents the various stages of the revolutionary OPT method. Clients will progress through the phases of training at regular intervals, with the specific phases and progression depending on goals and progress and conditioning. Most clients will cycle between 2-4 of the 7 phases, which include the following:

Corrective Exercise Training (CET) correctsmuscle imbalances, reconditions injuries, preparesbody for training, prevents training overload,enhances adaptation, improves the body’s work capacity and improves stabilization strength. In this phase, we work with fairly low intensities, repetitions can range from 15-25.
Integrated Stabilization Training (IST) improves neuromuscular efficiency, functional strength, core strength, dynamic stabilization and functional flexibility. Exercises increasing challenge the core and balance and we work with moderate intensities, repetitions can range from 12-20.
Stabilization Equivalent Training (SET) enhances stabilization strength and endurance during functional movement while increasing muscle mass, enhancing metabolism and improving stabilization strength. SET combines a stable exercise with one done in a less stable environment, such as a machine chest press and a pushup or stability ball press, intensities increase and reps range from 8-12 or 15.
Muscular Development Training (MDT) increases muscle mass for athletes such as football players and bodybuilders. We work at higher intensities with minimal rest, and reps range from 6-12.


Maximal Strength Training (MST) improves motor-unit recruitment, motor-unit synchronization and peak force. This is the highest intensity phase, reps range from only 1-5, rest period is 3-5 minutes.
Elastic Equivalent Training (EET) enhances neuromuscular efficiency and power production, especially for athletes who need to express force quickly. Similar to SET, this phase combines a strength and maximum power exercise, ranging from 5 adn 10 reps each to 3 and 8 reps each.
Maximal Power Training (MPT) increases speed strength and creates neuromuscular adaptations through an entire range of motion. Exercises use low weight, about 5-8% of body weight, but are done at very fast speed.

Assessing and Training for Better Posture: UPPER EXTREMITY POSTURAL DISTORTION

Part 3 of a series of 3 articles:
Some of the problems this posture can lead to include headaches, a painful nerve impingement in the shoulder, rotator cuff problems, and labored breathing or snoring. From an exercise standpoint, the body is not in an optimal position to perform many exercises such as overhead shoulder press, curls, chest press or fly, and so on. Individuals with this posture frequently mistake the soreness they experience in their upper back as muscle tightness when in fact the muscles are weak and extended - they need to be strengthened and not stretched.
