Because TLim is assumed to be a useful tool for intermittent training prescription, in the present study athletes completed five intervals at the vVO2max for a duration equal to 50% of the TLim, interspersed with an active recovery at 60% of the speed corresponding to vVO2max for a duration equal to the time of effort (i.e., 1:1 work:recovery ratio). The running speed during the HIIT was monitored by a GPS (GPS Forerunners 305).
