A comprehensive assessment of the cross-training effect in ankle dorsiflexors of healthy subjects: A randomized controlled study.

•A crossed transfer of peak torque and work is reported in ankle dorsiflexor muscles.•Work increased more than peak torque, depending on the angular velocity employed.•Performance gains were significantly larger in the untrained than trained muscles.•Peak torque and work contribute in a different proportion to muscle strength.•Analysis of peak torque, work and their ratio allows a full assessment of strength.
