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 deepwater 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 (Vo 2 max) by matching specific stride frequencies or running speeds. Vo 2 max, 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. Vo 2 max (DWR: 48.9 +/- 5.7 ml.kg(-1).min(-1); TMR: 59.2 +/- 5.6 ml.kg(-1).min(-1); p < 0.001) and HRmax (DWR: 174.1 +/- 9.6 beats.min(-1); TMR: 191.2 +/- 6.9 beats.min(-1); p < 0.001) were each lower during DWR vs. TMR.
