NCT02511964

Brief Summary

The objective was to determine the effect of six running sessions of high intensity interval training (HIIT) at 1% and 10% incline on VO2max, peak of velocity (VPeak), and time limit of 1% (TLim1%) and 10% (TLim10%) of inclination, as well as the influence of the specificity of training on performance in the different inclines.
