Calculation of times to exhaustion at 100 and 120% maximal aerobic speed
The aim was to compare physiologic responses during exhaustive runs performed on a treadmill at 100. and 120% maximal aerobic speed (MAS: the minimum speed that elicits V O2max). Fourteen subelite male runners (mean+/-SD; age=27+/-5 years; V O2max=68.9+/-4.6 ml.kg- 1.min- 1; MAS=21.5+/1km.h-1) participated. Mean time to exhaustion (t) at 100% MAS lim100% (269+/-77s) was similar to those reported in other studies. However, there was large variability in individual t MAS (CV=29%). MAS was positively. lim100% correlated with V O (r=0.66, p< 0.05) but not with t MAS 2max lim100% (r=-0.50, p < 0.05). t MAS was correlated with t at 120% MAS lim100% lim (r=0.52, p< 0.05) and to blood pH following the rest at 120% MAS (r=-0.68, p< 0.05). The data suggest that running time to exhaustion at MAS in subelite male runners is related to time limit at 120% (t) MAS. Moreover, lim120% anaerobic capacity determined by the exercise to exhaustion at 120% MAS can be defined as the variable 'a' in the model of Monod and Scherrer (1954).
