Abstract

Introduction: Karate is a highly popular martial art that involves participants from various age groups. In the kumite category, athletes are required to have optimal physical abilities such as speed, agility, and endurance to maintain competitive advantage.

Objective: Therefore, this study aims to compare the effects of plyometric training and ladder drills on speed, agility, and VO2max in karate athletes.

Methodology: The participants in this study included 30 karate (kumite) athletes aged 18-20 years with an average weight of 60.88±7.5 kg, who were divided into three groups: (A1; n=10) control group, (A2; n=10) plyometric group, and (A3; n=10) ladder drill group. Training was conducted with a frequency of 3x/week for 6 weeks. Speed, agility, and VO2max were measured before and after the intervention in all groups. Data analysis was conducted using one-way ANOVA followed by the Least Significant Difference (LSD) post-hoc test with a 5% significance level.

Results: The results showed that plyometric and ladder drill training for 6 weeks significantly improved the physical performance of karate athletes (p ≤ 0.05). Plyometric training was proven to be more effective in increasing sprint speed and aerobic capacity (p ≤ 0.05), while ladder drill training was more effective in improving agility (p ≤ 0.05).

Conclusions: This study found that the use of plyometric and ladder drill training in karate athletes is highly effective in improving speed, agility, and VO2max in Kumite athletes, providing practical guidance for coaches in designing effective and targeted training programs to enhance the physical performance of karate athletes.
