Key result
The ratio of one-leg to two-leg cycling aerobic capacity varied widely (0.58-0.96) and was primarily determined by one-leg V(O2peak) (r=0.71, P<0.0005) and muscle volume.
Cross-Sectional (n=71)
Effect estimate: r = 0.71
p-value: p=< 0.0005
Conventional endurance training prescribed at a set percentage of whole-body VO2max results in highly variable training stimuli for the leg muscles due to individual differences in muscle volume and single-leg VO2peak.

Conventional %VO2max prescriptions may yield inconsistent leg stimuli; hypothesis-generating for single-leg VO2peak-guided personalization.
McPhee et al. (2009) conducted a cross-sectional in Sedentary (n=71). One-leg cycling muscle aerobic capacity (V(O2peak)) vs. Two-leg cycling whole-body maximal oxygen uptake (V(O2max)) was evaluated on Ratio of one-leg cycling muscle aerobic capacity to two-leg cycling whole-body maximal oxygen uptake (Ratio(1:2)) (r = 0.71, p=< 0.0005). The ratio of one-leg to two-leg cycling aerobic capacity varied widely (0.58-0.96) and was primarily determined by one-leg V(O2peak) (r=0.71, P<0.0005) and muscle volume.
