NCT02018718

Brief Summary

The aim of this study is to demonstrate and quantify the micro architecture and micro vascular changes within skeletal muscles after marathon using 3T MRI (diffusion tensor and arterial spin labeling). Apparent diffusion coefficient, fractional anisotropy and flow parameters will be registered before and after the long-distance run on the lower leg. Axial T1 and axial SPAIR sequences will also be applied at the same time.Stress ox and inflammatory markers will be collected in blood and urine samples and compare with both MRI and Near-infrared spectroscopy (NIRS).

Outcome Measures

Primary Outcomes (1)

  • Fractional Anisotropy (FA) measure

    The measures will be made from sequences echoplanar (EAR), and will be extracted by post-treatment software Siemens untitled " Syngo" and "FSL", allowing a distortions correction.

    at 4 days

Secondary Outcomes (1)

  • Apparent Diffusion Coefficient (ADC) value

    at 4 days

Study Arms (1)
