Abstract
[Purpose] Subjects practiced crossing a net for 2 minutes, once a week for 6 weeks, and we measured the effects on net-crossing distance, and total path length, unit path length, unit path area, and circumferential area of body sway. [Subjects] The subjects were 12 men with an average age of 23.8 years. [Method] We conducted balance training of crossing a four-meter-long net, set at a height of 30 cm, for 2 minutes, once a week for 6 weeks. Before and after the training, we measured and compared the net-crossing distance and body sway on both legs and on one leg, with both the eyes open and closed. [Results] The net-crossing distance significantly increased after the training. There were significant reductions in: total path length, unit path length, and unit path area in one-leg standing on the right leg with the eyes open; in total path length and unit path length in one-leg standing on the right leg with the eyes closed; and in unit path area in one-leg standing on the left leg with the eyes open. [Conclusion] Net-crossing practice for 2 minutes once a week for 6 weeks improved balance factors.
