Effects of Vertical Water Training on Knee Extensors Strength in Swimmers

Muscle strength is one of the most important motor qualities, which largely influences the speed of execution of movements and activities that requires strength and skill. Muscle strength is a fundamental property of human performance, which provides important information on effort capacity by assessing the effects of training. In this study we investigated a group of fifteen athletes, swimmers, assessing knee extensor strength. We can see the average value over a time interval of 5 seconds of maximal isometric force moments measured in two different angles of knee extensor muscles, 1000 and 1200. Measurements were performed using the Isokinetic Kin-Com ® Dynamometer. The research results show an improvement in muscle strength after six weeks of weight training in water.
