Abstract
isometric dynamometry. Models of best fit for gross oxygen cost and gross caloric unit cost were observed across the majority of velocities when the leg extensor/flexor strength ratio and handgrip strength were combined (R2 = 0.207–0.525 and R2 = 0.152–0.475, respectively). Additionally, the oxygen cost differed statistically for
the majority of velocities when participants were split by the median of leg extensor strength (12.3–26.3 ml∙kg−1∙km−1, p < 0.05) and the average of all strength variables (13.9–30.3 ml∙kg−1∙km−1, p < 0.05). Our data underline the importance of maintaining maximal strength in order to perform activities with low to moderate oxygen demands.
