Participants performed a progressive Copenhagen Plank exercise program twice weekly for 4 weeks in addition to their regular soccer training.

All sessions were supervised by a strength and conditioning coach.

Isometric Hip Adductor Strength
Isometric hip adductor strength of the dominant and non-dominant limbs was assessed using a Lafayette handheld dynamometer during the long-lever squeeze test. The highest value of three maximal voluntary isometric contractions was recorded and expressed in Newtons (N).
Time frame: Baseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)
Countermovement Jump Height
Countermovement jump height was measured using a Chronojump contact platform. Participants performed three jumps with their hands on their hips, and the highest jump height (cm) was recorded.
Time frame: Baseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)
