Mode Specific Effects of Isokinetic Training of Hamstring on Hamstring to Quadriceps Ratio

Several studies in past have tried to examine the mode specificity of concentric and eccentric training of different muscles and at different angular velocities i.e. whether concentric training will increase the concentric strength only or both concentric and eccentric strength and whether eccentric training will increase eccentric strength only or both eccentric and concentric strength.

Since conflicting reports are available regarding mode specificity of eccentric and concentric isokinetic training therefore one study was needed that can examine the mode specificity of these training in hamstring muscles at slow angular velocity. The present study aimed to examine the mode-specific effects of six weeks of isokinetic concentric and eccentric training of the hamstring muscle at slow angular velocity on the PTecc/PTcon, AT, DT, and TPT.
