The aim of this study is to examine the effects of different plyometric training methods on the
biomotor and taekwondo technical performance of 14-16-year-old taekwondo athletes. The study
utilized two different training methods: plyometric exercises on sand and plyometric exercises on
taekwondo mats, with a control group performing only regular taekwondo training. The study
included 66 athletes, all with at least 5 years of taekwondo experience, from Trabzon, Turkey, in
2024. Participants were divided into two experimental groups: Group 1, performing plyometric
exercises on sand, and Group 2, performing plyometric exercises on taekwondo mats. After an 8-
week training program, biomotor and technical performance tests were applied to all groups for
comparison. The data were tested for normal distribution using the Kolmogorov-Smirnov test, and
since the data did not show normal distribution, non-parametric tests were used for analysis.
Wilcoxon tests were applied for within-group comparisons, while Kruskal-Wallis tests were used for
between-group comparisons. In cases where significant differences were found, Post hoc multiple
comparison tests with Bonferroni correction were used to identify which groups showed the
differences. The results showed that all groups demonstrated significant improvements in biomotor
and technical performance parameters after the training programs. Group 1, the sand-based
plyometric training group, showed more pronounced improvements in speed, agility, jump, balance,
and technical performance parameters. The findings suggest that sand-based plyometric training has
a significant impact on sports requiring speed, power, endurance, and technical skills, such as
taekwondo.
