Clinical Report: Evaluation of Neurophysiological Changes Following Exercise Training

Overview

This systematic review and meta-analysis evaluated the effects of exercise training on TMS-derived neurophysiological markers and motor performance in healthy adults. Statistically significant improvements were observed in both areas.

Background

Transcranial magnetic stimulation (TMS) is a non-invasive technique used to assess motor cortical and corticospinal function. Understanding how structured exercise training influences TMS-derived markers and motor performance is crucial for optimizing rehabilitation strategies. This systematic review aims to clarify these effects through a comprehensive analysis of randomized controlled trials.

Data Highlights

Key Findings

• 12 randomized controlled trials were included in the analysis.
• Statistically significant pooled effects were observed for TMS-derived markers (Hedges' g = 0.53).
• Motor performance also showed significant improvement (Hedges' g = 0.58).
• Moderate heterogeneity was noted for both outcomes (I² = 64.8% for TMS markers, 54.0% for motor performance).
• Subgroup analyses suggested potential differences by intervention duration and training modality, but findings were hypothesis-generating.
• Certainty of evidence was assessed as moderate due to risk of bias and inconsistency.

Clinical Implications

Further research is needed to establish definitive training parameters regarding exercise training's effects on motor performance and neurophysiological markers.

Conclusion

Further research is necessary to confirm the findings and their applicability.
