The relationship between skeletal muscle DTI metrics and athletic performance in track and field sprinters
Motivation: To optimize athletic performance, it is needed to understand the characteristics of muscles. Diffusion tensor imaging (DTI) can reveal muscle microstructure. Goal(s): To clarify the relationship between changes in DTI metrics of the tibialis anterior (TA) after dorsiflexion exercise and Wingate test metrics, which assess anaerobic capacity, and athletic records. Approach: Twenty male sprinters underwent MRI scans before and after dorsiflexion exercise. DTI metrics and the cross-sectional area (CSA) of the TA were analyzed for correlations with performance metrics. Results: λ3 before exercise showed positive significant correlation with athletic records. CSA consistently showed significant correlations with the Wingate power and peak power. Impact: Our findings demonstrated that DTI has the potential to evaluate muscle microstructure and for developing training strategies and optimizing performance.
