The book STRETCHING was first self-published by Bob and Jean Anderson in 1975 when fitness awareness was in its infancy. In 1980 Shelter Publications revised and published STRETCHING (Random House, the distributor) and since then STRETCHING has sold over three million copies in the U.S. And has been published in 24 languages for worldwide distribution.In 2000 the 20 th Anniversary edition of the STRETCHING book was published by Shelter Publications (distributed by PGW, Berkeley CA). This edition contained 25 new stretching routines, the sections on nutrition, walking/running, cycling, strength development were omitted (our book GETTING IN SHAPE covers these topics), there were new sections on PNF stretching and the use of body tools, and it was made available in a spiral binding by Stretching Inc.Now there is a 30 th Anniversary edition of STRETCHING.
Stretching By Bob Anderson
A stretchingIn its most basic form, stretching is a natural and activity; it is performed by and many other. It can be accompanied. Stretching often occurs instinctively after waking from sleep, after long periods of inactivity, or after exiting confined spaces and areas.Increasing flexibility through stretching is one of the basic tenets of physical fitness. It is common for athletes to stretch before (for ) and after exercise in an attempt to reduce risk of injury and increase performance.: 42Stretching can be dangerous when performed incorrectly. There are many techniques for stretching in general, but depending on which muscle group is being stretched, some techniques may be ineffective or detrimental, even to the point of causing, instability, or permanent damage to the, and fiber.
The physiological nature of stretching and theories about the effect of various techniques are therefore subject to heavy inquiry.Although static stretching is part of some routines, a study in 2013 indicated that it weakens muscles. For this reason, an active dynamic warm-up is recommended before exercise in place of static stretching. Contents.Physiology Studies have shed light on the function, in stretching, of a large within the of skeletal muscles named. A study performed by Magid and Law demonstrated that the origin of passive muscle tension (which occurs during stretching) is actually within the, not extracellularly as had previously been supposed.Due to neurological safeguards against injury such as the, it is normally impossible for adults to stretch most muscle groups to their fullest length without training due to the activation of muscle antagonists as the muscle reaches the limit of its normal range of motion.
Types of stretches. Assisted stretching may be performed when the athlete is unable to stretch optimally independently. For example, during cramping of the hamstrings, assistance in stretching out the muscles may help.Stretches can be either static or dynamic, where static stretches are performed while stationary and dynamic stretches involve movement of the muscle during the stretch. Stretches can also be or passive, where active stretches use internal forces generated by the body to perform a stretch and passive stretches involve forces from external objects or people to facilitate the stretch. Stretches can involve both passive and active components. Dynamic stretching Dynamic stretching is a movement based stretch aimed on increasing blood flow throughout the body while also loosing up the muscle fibers. Standard dynamic stretches typically involve slow and controlled active contraction of muscles.

An example of such a dynamic stretch are lunges. Another form of dynamic stretching is ballistic stretching, which is an active stretch that involves bouncing or swinging back and forth at a high speed in order to take a muscle beyond its typical range of motion using momentum. Ballistic stretching may cause damage to the joints. Static stretching The simplest static stretches are static-passive stretches, which bring the joint to its end range of motion and hold it there using external forces. There are more advanced forms of static stretching, such as proprioceptive neuromuscular facilitation (PNF), which involves both active muscle contractions and passive external forces.: 42 PNF stretching may involve contracting either the antagonist muscles, agonist muscles, or both (CRAC). Effectiveness. A athlete stretchingStretching has been found both effective, and ineffective based on its application for treatment.Although many people engage in stretching before or after exercise, the has shown this has no meaningful benefit in preventing specifically muscle soreness.Stretching does not appear to reduce the risk of injury during exercises, except perhaps for runners.
There is some evidence that pre-exercise stretching may increase athletes' range of movement.There are different positives and negatives for the two main types of stretching: static and dynamic. Static stretching is better at creating a more intense stretch because it is able to isolate a muscle group better. But this intense of a stretch may hinder one's athletic performance because the muscle is being over stretched while held in this position and, once the tension is released, the muscle will tend to tighten up and may actually become weaker than it was previously.
Also, the longer the duration of static stretching, the more exhausted the muscle becomes. This type of stretching has been shown to have negative results on athletic performance within the categories of power and speed.Dynamic stretching, because it is movement-based, may not isolate the muscle group as well or have as intense of a stretch, but it is better at increasing the circulation of blood flow throughout the body, which in turn increases the amount of oxygen able to be used for an athletic performance. This type of stretching has shown better results on athletic performances of power and speed, when compared to static stretching.However, both of these types of stretching have been shown to have a positive impact on flexibility over time by increasing muscle and joint elasticity, thus increasing the depth and range of motion an athlete is able to reach.
This is evident in the experiment 'Acute effects of duration on sprint performance of adolescent football players.' In this experiment, football players were put through different stretching durations of static and dynamic stretching to test their effects. They were tested on maximum sprinting ability and overall change in flexibility. Both static and dynamic stretching had a positive impact on flexibility but, whereas dynamic stretching had no impact on sprint times, static stretching had a negative result, worsening the time the participants were able to sprint the distance in. While the duration of stretching for dynamic had no impact on the overall results, the longer the stretch was held for static, the worse the results got, showing that the longer the duration of stretching held, the weaker the muscle became.
