INTRODUCTION: To confirm the effects of 12-week K-Bar weight training on body alignment changes.
METHODS: The K-Bar weight training was applied to 18 junior elite athletes(age;14.25±1.05 years, height; 160.53±8.06cm, weight; 48.42±8.18kg, BMI; 19.00±1.98kg·m2) at physical education middle schools in S City four times per week for 12 weeks. Changes to their height, trunk length, and weight were compared and analyzed before and after the training.
RESULTS: The subjects’ height increased from 160.53±8.06cm before the training to 161.14±8.11cm(by about 0.38%) after the training in a statistically significant level(p<.01). Their trunk length also increased from 401.56±55.54mm to 416.78±64.58mm, but the increase was not statistically significant(p=.088). And their weight increased from 50.69±10.36kg before the training to 53.98±10.59kg after the training, and the increase was statistically significant(p<.01).
CONCLUSION: Possibility that acquiring the right posture through K-Bar weight training once a week for 12 weeks can have positive effects on body alignment.
