Abstract
This study aimed to clarify the influence of training using slackline on balance ability. The subject was a rugby player of 18 healthy male college students. Subjects were divided into three groups (slack line group; SL, front and side bridge group; FS, control group; Cnt), training was conducted twice a week for 4 weeks. We measured center of gravity fluctuation, muscle strength, reaction jump test before and after training, ratings of perceived exertion (RPE) was recorded every time immediately after training. The speed of the center of gravity fluctuation was
significantly decreased after SL and FS training. The back strength did not change between SL and FS, and Cnt showed a decreasing trend. The value of RPE was significantly lower in SL than in FS. It was suggested that the training using the slack line improved the balance ability as much as the stabilization type trunk training, and the subject felt the training strength small.
