Abstract

The relationship of 11 measures of trunk and lower limb flexibility to the economy of treadmill walking and jogging as measured by steady‐state oxygen consumption (VO~2~) was studied. Subjects (38 women, 62 men, aged 20–;62 years) were tested at six speeds between 53.6 and 187.7 m/min. By combining scores from all flexibility tests, and beginning at speeds of 107.3 m/min, the β€œtightest” third used significantly less O~2~/m/kg (9%, p < 0.05) than the β€œloosest” third, with β€œnormals” in between. Two tests, trunk rotation and lower limb turnout, gave the best separation for walking/jogging economy, with the β€œtightest” third differing significantly from the β€œloosest” (8–12%) at all speeds tested (ANOVA with Scheffe). We conclude that nonpathological musculoskeletal tightness was associated with a decreased steady‐state VO~2~ for treadmill walking and jogging.
