The effect of contrast training in increasing taekwondo athlete’s strength and power

Abstract

Purpose. This study aimed to examine the effects of contrast training on taekwondo athletes' strength and power. Contrast training, which combines heavy and low loads in the same training session, was investigated to see if it could improve the taekwondo athletes’ performance. Material and methods. In an experimental study with a pre-test-post-test control group design, 10 taekwondo athletes underwent contrast training for seven weeks. This training served as the independent variable, whereas strength and power were the dependent variables. Following that, the data were evaluated using multiple statistical tests, including Levene's test for variance homogeneity and the Kolmogorov-Smirnov test for data normality. The independent samples t-test or ANOVA was also performed to compare the means of the contrast training group and the control group. Results. Athletes were placed into two groups in this experimental study: the treatment group and the control group. According to the findings of this study, contrast training has a substantial influence on boosting taekwondo athletes’ strength and power. When compared to the control group, the contrast training group had higher average strength and power (p < 0.05). The contrast training group had an average post-test strength of 6.868 while the control group had an average post-test strength of 6.766. Conclusions. This study has found that contrast training has a significant positive effect on developing taekwondo athletes’ strength. Taekwondo athletes who received contrast training had higher average strength and power than the control group (p < 0.05). Thus, it can be concluded that contrast training is an effective strategy for enhancing taekwondo athletes’ strength and power.
