Keywords

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

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.

Interventions

BEHAVIORALCopenhagen Plank Exercise Program

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.

Design outcomes

Primary

MeasureTime frameDescription
Isometric Hip Adductor StrengthBaseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)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).

Secondary

MeasureTime frameDescription
Countermovement Jump HeightBaseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)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.
