A comparison between sprint training vs. resistance training and their effects on speed, strength, power and muscle endurance in college aged males

The purpose of this study was to determine whether the Power Pull device provides consumers with a legitimate training device that maximizes the athlete's speed, strength, power and muscle endurance. The measured variables consisted of: (1) speed as measured by the 40-yard dash, (2) strength as measured by a one repetition maximum in the squat, (3) power as measured by the vertical jump and long jump and (4) muscular endurance as measured by the 70 percent of one repetition maximum to failure in the squat. Upon approval from The University of Southern Mississippi Human Subjects Protection Review Committee, twenty-three college-aged males served as subjects. Each group underwent a pre, mid and post-test. Using the results of the pretest, subjects were match-paired and randomly divided into two groups. Group A participated in workouts involving the Power Pull device along with upper body strength training. Group B participated in traditional sprint training along with the same upper body strength training as Group A. The subjects worked out twice a week for a 12 week period. The statistical analysis for this study included Analysis of Variance (ANOVA) and Multivariate Analysis of Variance (MANOVA) via SPSS software. The significant level was established at less than or equal to (p ≤ .05). Comparisons were made between the groups to establish whether there was any significant difference in speed, strength, power and muscular endurance. No statistically significant differences (p ≤ .05) between groups were noted for speed, power and muscular endurance. Although speed, power and muscular endurance were not significantly different between the groups, each group showed a significant increase over time for the pre, mid and post-test assessment times. However, a significant difference on the measure of strength both between and across groups was found, with the Power Pull group indicating significantly higher strength increases. Therefore, the Power Pull apparatus is a legitimate training device that can improve a person's performance in the measures of speed, power, strength and muscular endurance.
