Abstract:
The ultimate of this research was to compare the effect of different training interventions on RSA performance (repeated sprinting ability in 7X35meter). As antecedents of RSA; fatigue index (FI), explosive power and 40 meter sprinting speed were assessed after the different intervention training in three different groups. And the improvement achieved was evaluated. For this, three different groups (“resistance group”, “plyometric group” and “combined group”) were given different training intervention as an experimental design. The “resistance group” was given resistance training plus RSE, the “plyometric group” was given plyometric training plus RSE and the “combined group” was given resistance training combined with plyometric training plus RSE. This way, each group received their specific training 2 days per week The RSE, which is similar for all groups, was given 2 days per week for about 4 weeks. The pretest was carried out in each fitness element and specifically the RSA prêt-test score has been used to assign the subjects in each group randomly after they have given ranks (3 ranks/levels based on the pre-test RSA score). Each subject from each rank has been randomly allocated in each treatment group. On the basis of the pre-test and post-test value for each fitness element paired sample t-test was conducted with the critical value P<0.05. In addition, with an intention of comparing the means of the three groups post-test 40 meter sprinting speed and RSA score, one-way ANOVA has been carried out. Even though only the “plyometric group” and the “combined” achieved significant improvement in RSA test score, the variance between the groups was found to be non-significant. The three groups achieved a statistically significant improvement in the 40 meter sprinting speed, though the variance was found to be non-significant. As a main factor for RSA performance, aerobic fitness (VO2 max) or exercises/training intervention need to be included during RSA workouts. Unless we improve our aerobic fitness, our anaerobic fitness could not be too effective or functional to have a better RSA performance score. Furthermore, the length of the intervention during athletic training for performance or research purpose need to be more than 4 weeks for a visible or potent effect to be seen.
