Brief Summary

evaluate the effects of a 4-week Copenhagen Plank protocol on hip adductor strength and countermovement jump (CMJ) height in female soccer players and to determine whether adaptations were maintained during a 4-week follow-up.

Conditions

Strength Training Adaptations; Soccer Training

Keywords

Copenhagen Plank; female soccer; hip adductor strength; countermovement jump.

Outcome Measures

Primary Outcomes (1)

• 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).

  Baseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)

Secondary Outcomes (1)

• Countermovement Jump Height

  Baseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)

Interventions

Copenhagen Plank Exercise Program BEHAVIORAL

Participants performed a progressive Copenhagen Plank exercise program twice weekly for 4 weeks in addition to their regular soccer training. The program started with 2 sets of 8-10 repetitions per side and progressed to 3 sets of 12-15 repetitions per side during the final week. All sessions were supervised by a strength and conditioning coach.
