Most Effective Form of Stretching :: essays research papers
The American College of Sports Medicine defined fitness in 1990 by stating that physical fitness is ââ¬Å"a set of attributes that people have or achieve.â⬠(Cited in Dalgleish et al 2001) à à à à à This set of attributes can be further defined as cardiovascular fitness, muscular endurance, muscle strength, muscle endurance, motor skills and flexibility. à à à à à Cardiovascular fitness involves the heart and lungs supplying the required volume of oxygen to the working muscles. à à à à à Muscular endurance is the number of contractions or the length of time a muscle can contract before fatigue occurs. à à à à à Muscle strength is the maximum amount of force a muscle can generate in one contraction. à à à à à Motor skills is a general term, which covers co-ordination, speed, balance and power. à à à à à Flexibility is the range of motion (ROM) in a joint or in a series of joints. Flexibility is improved by stretching connective tissues, muscles and other soft tissue around a joint. Stretching exercises can be divided into different categories depending on the way the muscles and surrounding tissues are stretched. These forms of stretching are static stretching, dynamic stretching, ballistic stretching and proprioceptive neuromuscular facilitation (PNF). This report will define why athletes stretch and review current literature on each form of stretching and conclude from research which form is the most effective form of stretching. BENEFITS OF STRETCHING Stretching in sport was only used to warm athletes up before an event and cool them down after the event. Stretching was not used as a part of an athletes training programme until the benefits of stretching were recognised. Sigerseth (1971 cited in Elliot & Mester 1999) suggested that skilled performances could be improved by increasing the ROM around various joints. Performance can be improved due to stretching in three ways. à à à à à If range of motion is increased especially in throwing and racquet sports, more force or velocity can be produced. This is possible as this increases in ROM allows the throwing distance to increase and longer period of time in which force can be produced. This results in the speed of the racquet, bat or object being increased, which allows a more powerful, throw, kick or hit to occur. Examples of sports where this occurs is tennis, cricket, baseball and golf. Jobe and Moynes (1986 cited in Elliot and Mester 1999) Studied golfers and found that the higher skilled golfers had twice the range of trunk rotation compared to golfers of lesser skill. à à à à à Athletes who compete in sports where performance is judged on the aesthetics
