Mean value (SD) and confidence interval in brackets. Maximum values (max): mean values corresponding to the highest speed in each test series (NoMG, MGV, MGC). Submaximum values (sub): mean values corresponding to the series (NoMG, MGV, MGC) with the lowest maximum speed. Pre: pre-exercise values. ATlac (anaerobic lactate threshold): running speed corresponding to the lactate minimum (18) in Test B. * = significant.
