Introduction: Balance is a key component of motor control and plays a crucial role in maintaining postural stability during dynamic tasks such as landing and changing direction. Time to stability is a sensitive indicator of neuromuscular efficiency in restoring balance after mechanical perturbations.
Purpose of study: The purpose of this study was to examine the effects of balance training with and without stroboscopic glasses on TTS in physically active individuals.
Methods: In this Randomized Controlled Trial study, 39 physically active men aged 18–30 years were randomly assigned to three groups: balance training with stroboscopic glasses, conventional balance training, and control. Participants completed six weeks of progressive balance exercises. TTS during single-leg landings from 30, 50, and 70 cm was measured using a force plate. Data were analyzed using ANCOVA and Bonferroni post hoc tests with a significance level of 0.05.
Results: The results of the analysis of covariance (ANCOVA) indicated that both training groups showed a significant improvement in time to stabilization compared with the control group (p < 0.05).A significant main effect of group was observed at 30 cm (η² = 0.34, F = 8.40, p = 0.001), 50 cm (η² = 0.25, F = 5.33, p = 0.010), and 70 cm (η² = 0.30, F = 6.96, p = 0.003).
The reduction in time to stabilization was greater in the stroboscopic eyewear group at the 50- and 70-cm landing heights and was accompanied by larger effect sizes. At the 30-cm height, both training groups demonstrated similar improvements.
Conclusion: Intentional visual perturbation using stroboscopic glasses enhances reliance on proprioceptive and vestibular inputs, improving dynamic balance control. Integrating stroboscopic glasses into balance training programs may be an effective strategy to enhance performance and reduce the risk of lower-limb injuries in athletes.
