Experimental session
vastus lateralis stiffness
After the warm-up and baseline assessments (vastus lateralis stiffness, countermovement jump, and 10 m sprint time), the participants performed bilateral, unilateral CA, or no CA in a randomized order. The CA consisted of 3 sets of 5 bilateral drop jumps as a bilateral CA (B-CA) or 3 sets of 5 unilateral drop jumps as a stronger or weaker CA (S-CA or W-CA); depending on which limb it was performed). In the CTRL condition, no CA was applied. Following that, approximately at the 5
