Abstract: Objective To explore the characteristics of gait and surface electromyography (sEMG) of underwater treadmill training (UWTT). Methods From January to September, 2015, gait and sEMG parameters of ten healthy adults were synchronously collected using three-dimensional gait analysis system and sEMG systems on land and UWTT. Results When walking in self comfortable speed, compared with walk on land, there was significant increase in gait cycle (t=-11.411, P<0.001) and percentage of the swing phase (t=-5.252, P<0.05), significant reduction in walking speed (Z=-2.803, P<0.01) and step frequency (t=7.421, P<0.001). There was no significant difference in step strength (Z=-0.357, P>0.05). The integral electromyography of biceps femoris, gastrocnemius, tibialis anterior muscle were significant less than iEMG on land (t>3.984, P<0.01), but no significant difference of rectus femoris (t=0.054, P>0.05). Conclusion There are signifi-cant differences in gait and muscle contraction intensity between land walking and UWTT. The dynamic physiology and neural control of UWTT need further study.
