Summary
Response time during the modified Star Excursion Balance Test (mSEBT) improved with practice, indicating it is a learned skill. Muscular fatigue did not significantly impact response times in this study.
Area of Science:
- Biomechanics and Motor Control
- Human Performance and Exercise Science
Background:
- The Star Excursion Balance Test (SEBT) is widely used to assess dynamic standing balance.
- Response time (RT) is a crucial cognitive factor in postural control, but its integration with SEBT, especially under fatigue, is underexplored.
Purpose of the Study:
- To investigate response times during a modified SEBT (mSEBT).
- To examine the impact of muscular fatigue on response times during the mSEBT.
Main Methods:
- Sixteen healthy adults performed an mSEBT with an integrated response time task (Blazepod™).
- Participants completed the mSEBT before and after a low-intensity fatigue protocol.
- A 2x2x3 repeated measures ANOVA analyzed differences in mean RT across trials, fatigue states, and reach legs.
Main Results:
- Response time significantly improved across testing trials (p = 0.023), with Trial 3 showing faster RT than Trial 1 (p = 0.021).
- No significant differences in RT were observed between fatigue states or between the dominant and non-dominant reach legs.
Conclusions:
- Response times during the mSEBT improve with practice, suggesting a learning effect.
- Further research should explore extended familiarization and more intense fatigue states to better understand RT dynamics in the mSEBT.
