The Effects of Plyometric Training on 50 Meters Crawl Swimming Speed Performance in Swimmers
Abstract
Background and Aim: This research aimed to study and compare the effects of plyometric training on crawl swimming speed performance in swimmers.
Materials and Methods: This research employed a quasi-experimental design. The subjects were selected from a population of 43 swimmers tested in a 50-meter freestyle swim. The times were recorded and ranked from highest to lowest. A total of 20 swimmers were selected using the ranking method, and they were divided into two equal groups of 10 by drawing lots: an experimental group and a control group. The experimental group performed plyometric training, while the control group underwent traditional training. Both groups trained twice a week for eight weeks. The 50-meter crawl stroke speed was measured before and after the experiment. The data were analyzed using means, standard deviations, and a t-test to determine the significant differences in performance before and after the experiment, as well as between the two groups.
Results: After eight weeks of training, the results indicated that: 1) The 50-meter crawl stroke speed in both the control and experimental groups improved significantly compared to pre-training levels (p < .05). 2) There were significant differences in the 50-meter crawl stroke speed between the control and experimental groups, with the experimental group showing greater improvement (p < .05).
Conclusion: The findings of this study demonstrated significant improvements in swimming speed for both the conventional and plyometric training groups at the 0.05 significance level. However, the plyometric training group showed notably greater improvements in speed compared to the conventional training group. These results suggest that plyometric training enhances 50-meter freestyle swimming performance by improving muscle strength, speed, and coordination. Incorporating plyometric exercises into conventional training programs could provide athletes with a competitive edge, as it focuses on both power development and the quick muscle response necessary for optimal swimming performance.
