There has been very little research completed in the area of weight training for women. Many women have weight training facilities and equipment available to them, but for many reasons do not take advantage of it. There are many misconceptions of weight training that are of concern to the female, such as; loss of flexibility, developing large, bulky muscles and traits of masculinity. A problem also arises in the knowledge and proper use of equipment. Until the present time, the two main concepts of resistive exercise have been isotonic and isometric. In 1966, Ferrine pioneered the first isokinetic exerciser. Isokenetic exercise employs a simple physical principle which is controlling the speed of the body movements produced by the contracting muscles. This type of exercise allows maximum loading of the muscles throughout the full range of movement, due to an accommodating feature. The machines are designed to adjust constantly to the muscle contraction of the user and to give optimal resistance whatever the angle of pull. This type of resistance training allows for specific training of a desired muscle group. More research is needed in the area of isokinetic training to determine the effect it has upon females. If proven to be effective, this type of exercise might then be used by physical educators, physical therapists, coaches, trainers, and athletes to strengthen muscles and prevent injuries. The purpose of this investigation was to compare the effectiveness of isotonic training, isokinetic training and jumping practice on vertical jumping ability of selected South Dakota State University women enrolled within the Fitness and Lifetime Activities Program.
