Evaluating the Effect of Six Weeks Strength Training on the Speed of Sprinters Among Debre Markos University Male Sport Science Students, Ethiopia
Purpose: The purpose of this study was to investigate the effects of six weeks strength training interventions on speed performance of sprinters. Furthermore, the purpose was to compare the effects of strength training on some anthropometry of sprinters among University sport science students. Methods: To achieve the purpose of the study, six male student athletes were selected as subjects purposively. The study was formulated as experimental (pre and post-test) study design. All Selected subjects participated on proposed exercises training program for six consecutive weeks, with four days per week for a total of thirty two training sessions. The outcome variables were measurement of calf, thigh, chest, biceps and triceps circumference and 100m and 200m speed. The data were analyzed using paired t-test with comparison of means at 95% confidence intervals. Results: The results indicated there were significant improvement on selected variables weight, biceps and triceps muscle circumference and speed of 100m and 200m (p< 0.05). In other variables like calf, thigh, and chest had a change but significant differences were not observed. The mean differences (MD) between pre and post tests for weight were 1.4, biceps triceps 2.5, chest 0.5 thigh 0.833, calf 0.5 and speed of 100m 0.143, 200m 0.6. Conclusion: This study confirmed that strength training has an impact on speed and anthropometry. The study showed that student athletes who were exposed to six weeks strength exercise training have positive outcomes on speed.
