The Effects of 6-Week Training with Junior Weight Vest (JWV) for Arm Strength and Running Speed in Junior Martial Arts Athletes

Abstract

Strength and speed are very important components in martial arts. The use of Junior Weight Vest (JWV) in training has the potential to increase strength and speed of junior martial arts athletes. This study aimed at determining the effect of wearing JWV on arm strength and running speed of junior martial arts athletes aged 9-15 years, totalling 20 people. This research was conducted for 6 weeks, 3-4 times per week and 50 minutes per day. Two groups were utilized, namely control group and experimental group using MANOVA analysis. The control group was treated with martial arts training using their own body weight and the experimental group was treated with martial arts training by wearing JWV weighing 650 grams -1000 grams. The conclusions of the study are: 1) there was a difference in the effect of using JWV on arm strength (p 0,001 < 0,05), 2) there was a difference in the effect of using JWV on running speed (p 0,001 < 0,05), and 3) there was a difference in the effect of simultaneously using JWV and Non JWV on arm muscle strength and running speed in junior martial arts athletes (p 0,000 < 0,05). This research shows that the arm strength and running speed of junior martial arts athletes can be increased by using JWV. Trainers, sport teachers, parents, community, sports organizations, and leaders in the field of sports can be informed that the results of this research have a measurable benefit in increasing arm strength and running speed using the Junior Weight Vest (JWV). The application of JWV in other sports such as badminton, basketball, volleyball, tennis, and even swimming can be considered as a topic for further researches.
