Muscle Activity and Physiological Responses During Running in Water and on Dry Land at Submaximal and Maximal Efforts

Masumoto, K, Mefferd, KC, Iyo, R, and Mercer, JA. Muscle activity and physiological responses during running in water and on dry land at submaximal and maximal efforts. J Strength Cond Res 32(7): 1960–1967, 2018—We investigated muscle activity, oxygen uptake, heart rate, and rating of perceived exertion during running in water and on dry land at submaximal and maximal efforts. Eleven recreational runners performed deep-water running (DWR) and treadmill running (TMR) graded exercise tests on separate days. On the third-test day, the subjects exercised at their 60, 80, and 100% of maximal oxygen uptake (V[Combining Dot Above]O2max) by matching specific stride frequencies or running speeds. V[Combining Dot Above]O2max, maximal heart rate (HRmax), and rating of perceived exertion at maximal effort (RPEmax) were measured. Furthermore, muscle activity from the rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius were measured. V[Combining Dot Above]O2max (DWR: 48.9 ± 5.7 ml·kg−1·min−1; TMR: 59.2 ± 5.6 ml·kg−1·min−1; p 0.05). Muscle activity from all tested muscles was different between modes (p
