The Effect of Hand Band Resistance Training And Dumbbell On The Speed Ability of Chudan Tsuki Punches In Karate Athletes Inkanas

Abstract

Punching speed is one of the most important determinants of performance in karate, particularly in kumite competitions, where athletes are required to execute fast and accurate attacks to obtain points. However, observations at the INKANAS Tribun Timur Branch in Makassar City indicated that athletes exhibited suboptimal chudan tsuki punch speed, which affected their competitive performance. Therefore, this study aimed to examine the effects of hand resistance band training and dumbbell training on the speed ability of chudan tsuki punches among karate athletes. This study employed a quasi-experimental design using a two-group pretest–posttest approach. Twenty karate athletes were selected through random sampling and divided equally into a hand resistance band training group and a dumbbell training group. The intervention was conducted for 16 training sessions. Data were collected using the Chudan Tsuki Punch Speed Test and analyzed using descriptive statistics, normality and homogeneity tests, as well as paired and independent sample t-tests with SPSS version 22. The results showed that the hand resistance band group improved significantly from a mean score of 25.70 ± 0.823 to 29.30 ± 0.823 (t = 22.045; p = 0.000). The dumbbell group also improved significantly from 25.50 ± 0.707 to 26.70 ± 0.675 (t = 9.000; p = 0.000). Furthermore, a significant difference was found between the two training methods (t = 7.723; p = 0.000), indicating that hand resistance band training was more effective than dumbbell training. In conclusion, both training methods positively affect chudan tsuki punch speed, with hand resistance band training providing superior outcomes.
