Effects of sprint training on leg strength

This study deals with the question of whether sprint training can contribute to strength gains in the lower extremities. In addition to sprint tests using light barriers the eccentric strength of the leg flexors with the hamstring board and the maximum strength including explosive strength of the leg extensors on a leg press were used for evaluation. The required data were collected at the sports centre in Rif. In total the data of 25 subjects (mean: age 26.3 years weight 72.9 kg) were presented and analysed in this study. There was a pre-test and a post-test which were separated by 6 weeks. The subjects were divided into two groups with the intervention group (n=13) having to perform sprint training twice a week. The control group (n=12) maintained their normal activities. The result shows that all variables were significantly increased by sprint training. The greatest improvements were achieved in hamstring strength. The study clearly confirms that not only competitive athletes but also hobby and recreational athletes can benefit from sprint training. Based on the results of this study sprint training can be considered as sport-specific strength training for athletes.
