What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Copenhagen Plank Exercise ProgramBehavioural
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.

|---|---|---|
| experimental group | Experimental | EXPERIMENTAL GROUP Receives: Behavioral: Copenhagen Plank Exercise Program |
| CONTROL GROUP | No intervention | Not described |
What is being measured
The primary outcome is the main question the study is designed to answer.
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).
Measured: Baseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)
Secondary outcomes (1)
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.
Measured: Baseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Isometric Hip Adductor Strength (time frame: Baseline, 4 weeks (post-intervention), and 8 weeks (4-week follow-up)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jul 2026.
