The purpose of this investigation was to determine the effect of selected explosive weight training exercises upon leg strength, free running speed, and explosive power. Twenty freshman male volunteer students at South Dakota State University were chosen from the investigator’s two activity classes by a table of random number to become subjects in the experimental group. The control group was a trampoline and handball activity class consisting of twenty freshmen male students at South Dakota State University. The subjects in the experimental group participated in a five-week explosive weight training program, during which they met for twenty training sessions; each session consisted of three circuits of explosive weight training. The control group continued in their regular activity classes. All subjects in both groups were tested at the beginning and at the end of the explosive weight training program. Leg strength, free running speed, and explosive power were investigated. The data collected during the testing were recorded and analyzed to determine what effect the explosive weight training program had upon leg strength, free running speed, and explosive power. A comparison was made between the experimental group and the control group; from this comparison a statistically significant improvement was noted in leg strength and free running speed in the experimental group. There was not statistically significant improvement in explosive power in either group in this investigation. (see more in text)
