Effect of Eccentric Training on Ankle Plantar Flexor Strength in Recreationally Resistance-Trained Adults

This study compared the effects of two 6-week eccentric plantar-flexor training programs on loaded heel-rise performance in cecreational strength-training adults. Forty participants were randomly assigned to either a modified heel-drop training group or a horizontal leg-press training group. Both groups trained three times per week for 6 weeks. Loaded heel-rise performance was assessed at baseline and after 2, 4, and 6 weeks of training. The primary outcome was the highest external load with which participants could complete five technically correct repetitions of the assigned unilateral plantar-flexor exercise.
