Beaudoin, C. M., & Whatley, J. (2001). An examination of flexibility and running economy infemale collegiate track athletes. Medicine and Science in Sports and Exercise, 33(5), Supplement abstract 128.

The relationships between lower limb and trunk flexibility and running economy were investigated in female track athletes (N = 10). Economy of running was measured by assessing VO2max, and three 10-min accommodation runs at 2.01 m/s.

Repeated measures of flexibility were highly correlated. Trunk rotations to both sides were moderately correlated with running economy.

Implication. Moderate levels of trunk rotational flexibility are associated with more economical running.
