BLS SPOTLIGHT ON STATISTICS SPORTS AND EXERCISE www.bls.gov/spotlight Sports and Exercise May 2008 What percentage of people (aged 15 years and older) who live in the United States participated in sports and exercise activities on an average day in recent years? About 16 percent. In comparison, consider that the number of people who watched television on an average day is roughly five times larger. These charts, which display data from the American Time Use Survey, take a closer look

The tensile behaviour of common engineering polymers Abstract A polymer is a macromolecule made of long chains of carbon atoms. This structure gives to the polymers special properties such as rubber elasticity. This investigation focuses on the rubber elasticity of the polymers. Different common polymers are tested on a machine that stretches the polymer at different speeds. The test shows that some polymers stretch whereas others break instantly due to the tensile force. The structure of the

widely throughout professional and college athletics as a performance test. An athlete’s vertical jump can effectively determine how explosive they are and how efficiently they utilize their strength in athletic movements. In fact, in the NFL, the single biggest predictor of success isn’t one’s size, speed, or strength, but rather their vertical jump! Vertical Jump I Know – So Tell Me How I Can Improve It! Of course the reason you bought this manual was because just like everybody else you’re wondering

TheVertical Jump Development Bible A sample 12-week cycle might look something like this: Week 1-3: Higher volume lower and moderate intensity jump training (i.e. single and double leg jumps, hops, skips – depth jumps up to 18 inches) Week 4-6: High volume weights + low volume low intensity jump training Week 7-9: Moderate volume accelerated weight training (jump squats, speed pulls) + low volume shock jumps (depth drops) Week 10-12: Low volume general weights + high volume depth jumps EXERCISE

limited, and claims made by companies and pseudo-experts can be misleading. The purpose of this review is to analyse the potential mechanisms by which muscles respond to vibration and to summarise current knowledge of the effects of vibration on human strength and power performance. IS VIBRATION A NATURAL STIMULUS? During all sporting activities our bodies interact with the external environment and experience externally applied forces. These forces induce vibrations and oscillations within the tissues
