New research shows that single-leg cycling drills may be a valuable way to address dominant/nondominant leg diﬀerences. University of Calgary researchers in Canada investigated aerobic performance in relation to leg dominance. What they found in a group of 12 young men was that both submaximal and maximal aerobic capacities were greater in the dominant leg than in the nondominant leg. The dominant leg, therefore, may not only be stronger, more coordinated and more powerful; it may also have more aerobic capability.
