Abstract

The objective of this research was to test the effect of a speed training versus strength training approach in power development. It was hypothesized that a speed-training program would be more efficient in power development than a strength program. Sixty-five football players participated in an off-season weight-training program. All players lifted three times per week and used the same program with one exception. Fifteen athletes performed a timed hip sled program, while the remaining 40 athletes performed a squat program designed to develop strength. The Margaraia-Kalamen (M-K) power test was used as a measure of power in watts. Baseline and follow-up weight/height2 (BMI), power clean, push press, squat and vertical jump measures were recorded. Using group comparison and paired t-tests, and analyses of covariance and ordinary least squares mathematical modeling procedures, no difference could be found between the two groups on any of the measures. Modeling was used to test the effect of the training group on power development while controlling for initial differences; no group differences in training effect were found. It was concluded that while speed training was not found to be superior to strength training, it could be an equivalent substitute. Future studies should evaluate a combined speed and strength approach for maximum efficiency in power development. Verf.-Referat
