This study aims to compare the effects of different training durations on a visual feedback-based balance training program by applying it with varying durations across different groups.
Participants were randomly assigned to three groups. The visual feedback balance training groups were divided into 10-minute, 20-minute, and 30-minute groups(n=16 per group).
For the visual feedback-based balance training program, the MFT Challenge Disc 2.0 (Germany) was used. This equipment consists of a 44 cm diameter force plate and specialized software.
To enhance participants' immersion in visual feedback, a 65-inch monitor was used during the training. The visual feedback-based balance training program was designed by referencing previous studies and included visual feedback-based posture adjustment training, dynamic balance training, and weight-shifting training with targets or pathways
The Wintack system (Medicapture, France) was used to measure the effects of the intervention. Participants' center of pressure (COP) and plantar pressure were measured using this device before and after the experiment.
To compare the effects between groups according to the intervention, one-way analysis of variance (ANOVA) was used. The statistical significance level was set at p 0.05.
For the 10-minute group, significant differences were observed in the left foot area(p0.05). In the 20-minute group, significant differences were found in the total COP length and total COP area(p0.05). For the 30-minute group, significant differences were noted in the foot support areas(p0.05), as well as in the maximum and average pressure on both sides (p0.05). Additionally, significant differences were observed in the total COP length and total COP area.
Comparing the effects of visual feedback-based balance training based on training time, the 30-minute group showed a significant difference in the maximum pressure and Total COP length compared to the 10-minute group (p0.05), though there was no significant difference between the 20-minute and 30-minute groups.
Based on the results of this study, 10 minutes of VFBT training may only be effective in changing control of the foot support surface, but 30 minutes of training may show significant differences in control of the foot support surface and body sway.
Rather than improving performance through a long-term program, it may be effective to perform a program of at least 20 minutes or more to induce immediate improvement in balance ability during warm-up or before a game.
