First author, year Force/torque during shortening phase in a SSC Contraction modalities
(Conclusion of the article)
Blanpied, 1995 The average concentric force during shortening is higher for 50°/s stretch compared to 150°/s stretch Dependent on stretch velocity
Fukutani, 2015a After 1/4 of shortening: 329%, 1/2 of shortening 159% and ¾ of shortening 125% higher compared to pure shortening contraction.
Fukutani, 2015b 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, 2016 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; 2017 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)
Dependent on angular velocity
Svantesson, 2015 30% -170% higher compared to pure shortening contraction
(measurement of torque near to the middle of the shortening phase)
Dependent on angular velocity and sex, no influence of age
