Blanpied, |
The average concentric force during shortening is higher for 50°/s stretch compared to 150°/s stretch | Dependent on stretch velocity |
Fukutani, |
After 1/4 of shortening: 329%, 1/2 of shortening 159% and ¾ of shortening 125% higher compared to pure shortening contraction. | |
Fukutani, |
Joint torque is increased at any time during the shortening phase for the angular velocity of 150°/s compared to 30°/s. | Dependent on angular velocity |
Fukutani, |
Joint torque is only increased in the early phase of the concentric contraction in the SSC condition compared to a pure shortening condition. | Pre-activation plays an important role in torque enhancement. |
Fukutani; |
Joint torque is increased at any time during the shortening phase compared to pure shortening contraction. Compared to a SSC with a delay between stretch and shortening, torque is only increased in the early phase of shortening. | Elastic energy plays an important role in torque enhancement. |
Svantesson, 2014 | 75% -166% higher compared to pure shortening contraction (measurement of torque near to the middle of the shortening phase) |
