Training: Why Endurance Training Lacks Staying Power

By Chad Tackett, president of Global Health and Fitness.

Benefits of Flexibility Training
Flexibility is a joint's ability to move through a full range of motion. Flexibility training (stretching) helps balance muscle groups that might be overused during exercise or physical activity or as a result of bad posture. It's important to clearly understand the many benefits that result from a good flexibility program.

Improved Physical Performance and Decreased Risk of Injury
First, a safe and effective flexibility training program increases physical performance. A flexible joint has the ability to move through a greater range of motion and requires less energy to do so, while greatly decreasing your risk of injury. Most professionals agree that stretching decreases resistance in tissue structures; you are, therefore, less likely to become injured by exceeding tissue extensibility (maximum range of tissues) during activity.

Reduced Muscle Soreness and Improved Posture
Recent studies show that slow, static stretching helps reduce muscle soreness after exercise. Static stretching involves a slow, gradual and controlled elongation of the muscle through the full range of motion and held for 15-30 seconds in the furthest comfortable position (without pain). Stretching also improves muscular balance and posture. Many people's soft-tissue structures has adapted poorly to either the effects of gravity or poor postural habits. Stretching can help realign soft tissue structures, thus reducing the effort it takes to achieve and maintain good posture in the activities of daily living.

Reduced Risk of Low Back Pain
A key benefit, and one I wish more people would realize, is that stretching reduces the risk of low back pain. Stretching promotes muscular relaxation. A muscle in constant contraction requires more energy to accomplish activities. Flexibility in the hamstrings, hip flexors, quadriceps, and other muscles attaching to the pelvis reduces stress to the low back. Stretching causes muscular relaxation, which encourages healthy nutrition directly to muscles; the resulting reduction in accumulated toxins reduces the potential for muscle shortening or tightening and thus reduces fatigue.

Increased Blood and Nutrients to Tissues
Another great benefit is that stretching increases blood supply and nutrients to joint structures. Stretching increases tissue temperature, which in turn increases circulation and nutrient transport. This allows greater elasticity of surrounding tissues and increases performance. Stretching also increases joint synovial fluid, which is a lubricating fluid that promotes the transport of more nutrients to the joints' atricular cartilage. This allows a greater range of motion and reduces joint degeneration.

Improved Muscle Coordination
Another little-known benefit is increased neuromuscular coordination. Studies show that nerve-impulse velocity (the time it takes an impulse to travel to the brain and back) is improved with stretching. This helps opposing muscle groups work in a more synergistic, coordinated fashion.

Enhanced Enjoyment of Physical Activities
Flexibility training also means enhanced enjoyment, and a fitness program should be fun if you want to stick with it. Not only does stretching decrease muscle soreness and increase performance, it also helps relax both mind and body and brings a heightened sense of well-being and personal gratification during exercise.

As you can see, flexibility training is one of the key components of a balanced fitness program and should be a part of your exercise routine. Without flexibility training, you are missing an important part of overall health. Flexibility training provides many important benefits that cannot be achieved by any other exercise or activity. Good luck: I hope you enjoy all the wonderful benefits of an effective flexibility training program.

Stretching Principles and Guidelines
Flexibility is one of the key components of a balanced fitness program. Without flexibility training (stretching), you are missing an important part of overall health. Flexibility prevents injury, increases your range of motion, promotes relaxation, improves performance and posture, reduces stress and keeps your body feeling loose and agile. Although there is still some controversy over which flexibility exercises are the best and how often one should stretch. Most fitness professionals agree that the principles and guidelines of flexibility training that are about to be discussed are the safest and most effective.

Use Static Stretching
Static stretching involves a slow, gradual and controlled elongation of the muscle though the full range of motion and held for 15-30 seconds in the furthest comfortable position (without pain). This is the first and most important stretching principle. In our opinion, all stretches for each muscle group should be done by using this static form of stretching.

How often you should stretch is still not fully understood. Most professionals would agree however, that daily stretching is best, during and after exercise sessions. Frequent stretching will help you avoid muscular imbalances, knots, tightness, and muscle soreness created by daily activities and exercise.

Always Warm-Up Before Stretching
A warm muscle is much more easily stretched than a cold muscle. Never stretch a cold muscle, always warm-up first to get blood circulating throughout the body and into the muscles. A warm-up should be a slow, rhythmic exercise of larger muscle groups done before an activity. Riding a bicycle or walking works well. This provides the body with a period of adjustment between rest and the activity. The warm-up should last about 5-10 minutes and should be similar to the activity that you are about to do, but at a much lower intensity. Once you have warmed up at a low intensity for about 5-10 minutes and have gotten your muscles warm, you can now stretch.

Stretch Before and After Exercise
I recommend stretching both before and after exercise, each for different reasons. Stretching before an activity (after the warm-up) improves dynamic flexibility and reduces the chance of injury. Stretching after exercise ensures muscle relaxation, facilitating normal resting length, circulation to joint and tissue structures, and removal of unwanted waste products, thus reducing muscle soreness and stiffness. Body temperature is highest right after the cardiovascular exercise program and/or after strength training. In order to achieve maximum results in range of motion and to receive other benefits, it is highly recommended that you do static stretching at this point in your workout, just after your cardiovascular program and during or after your strength-training program.

Stretch Between Weightlifting Sets
Both strength training and flexibility training are so important for everyone. Those of you who have a hard time finding time to incorporate a strength training program into your lifestyle, can combine your stretching with your strength training programs. If you have had any experience in strength training, you know that for each exercise for each muscle group you train, you have a certain number of sets, usually between one and four. Between each set, you need to rest and let your muscle recover before going on to the next set. Well, what better use of your resting time than to stretch that specific muscle that you're currently training? Think about it, you've just done a set of 10 reps on the Bench Press. Now you have to rest, usually about one to two minutes before doing the next set. This is a great time to stretch your chest-- your chest is warm and you have time before you start your next set.

How often do you see people who neglect to warm up before their cardiovascular exercise or strength-training sessions? They begin going through their stretching routine before their muscles are even warm. It makes more sense to stretch each specific muscle between sets of strength training exercises. For example, if you are on a strength-training program where you do one exercise of three sets of 10 reps for each major muscle group in the body, you will want to work each muscle group one at a time starting with larger muscle groups and proceeding to smaller groups. Do your first set with relatively light weight to warm-up, then rest for a minute or so and then increase the weight and go onto the next set of 10 reps (or whatever your goal reps happens to be).

After the second set, your muscles should be warm and ready to be stretched. While resting before your third set, stretch the muscle that you have just trained, remembering the important principles of a static stretch, then proceed to your third and final set. Stretch the muscle one more time, even a little further. Go on to the next exercise for the next muscle group and after it is warm, do your stretch for that muscle, and so on. When you have gone through each of your strength-training exercises, you will have stretched each muscle without taking-up any more time.

Stretch Before and After Cardiovascular Exercise
If it is your day off from strength training and you are just doing your cardiovascular exercise routine, first warm-up for 5-10 minutes at a low intensity (50-60 percent of your maximum heart rate ) and stretch the muscles used. Proceed doing a cardiovascular exercise for at least 20 minutes at a intensity of 50-85 percent of your maximum heart rate (refer to the Global Health and Fitness Cardiovascular Exercise Program). Then cool down for 5-10 minutes at a low intensity (50-60 percent of your maximum heart rate). Now, because your muscles are very warm you should stretch each of the major muscle groups involved in the exercise, using the static stretching techniques we explained previously. For example, if you walked on the treadmill, you should stretch your quadriceps, hamstrings, calves, and lower back. Proper technique for each stretch is absolutely critical for achieving maximum effectiveness in any one specific muscle group. In addition to stretching those muscles used in the exercise, now is also a good time to go through a full body stretching routine--since blood has circulated throughout your body and warmed-up your muscles.

I hope you have found the information in this article helpful. You now have the knowledge to achieve the results you desire and the benefits your body deserves. Your greatest challenge, however, is not learning new stretching exercises or the proper technique; it's not learning how long to hold the stretch or the best time to stretch. Nor is it deciding when to try new stretching exercises. The greatest challenge facing you at this moment is deciding whether you are willing to take action and make time for yourself and make flexibility training a priority.

When you begin achieving great results, the excitement and fun you experience will make the change well worth the effort. Action creates motivation! Good luck: I hope you enjoy all the wonderful benefits of an effective flexibility training program.
