The sustainability of VO2max: effect of decreasing the workload
The study examined the maintenance of V O 2max using V O 2max as the controlling variable instead of power. Therefore, ten subjects performed three exhaustive cycling exercise bouts: (1) an incremental test to determine V O 2max and the minimal power at V O 2max (P V O max ), (2) a constant-power te...
