• Despite widespread use of balance training, the effects of day(s) per week (frequency) as one of the three training components (intensity, duration, and frequency) on the balance ability are as yet unclear. This study investigated the effects of different frequencies of balance training on the balance ability using a seesaw-like platform. In total, 35 of 40 healthy male subjects aged 20 to 22 yrs completed the study. The subjects were assigned to the following subgroups: (a) 1 d x [wk.sup.-1] training group (W1; n = 9); (b) 2 d x [wk.sup.-1] training (W2; n = 10); (c) 3 d x [wk.sup.-1] training (W3; n = 7); and (d) a control group without training (Control; n = 9). No significant difference in baseline of balance keeping time (BKT) among the four groups was confirmed. The training period was 8 wks. The subjects maintained balance as long as possible at each trial, and the BKT was determined by recording the platform movement and head acceleration for postural control. This trial was repeated 10 times a day consisting of a 1-day training session. After an 8-wk training period, absolute changes in BKT from baseline ([DELTA]BKT) in W2 and W3 were significantly larger than in W1 (P<0.01 and P<0.05, respectively). Moreover, pre-post comparison of [DELTA]BKT within W1 showed no significant training effect as well as the non-training control group. These findings indicate that balance training frequencies of more than 2 d x [wk.sup.-1] for at least 8 wks with 10 consecutive trials are effective in the improvement of balance ability.
