简要总结
The study aims to compare the effects of two different adduction exercises on adduction strength. Young male football players will be individually randomized to perform one of these exercises in addition to their normal training. The two exercise protocols are of 8 weeks duration and are matched in terms of total load.
详细描述
Methods Participants Male football players 16 years or older, who are participating in full team training in Greece, will be included in the study. The study will be conducted pre-season. During that time each player will have at least 4 training sessions and 1 match per week.
Exclusion criteria were
- any systematic resistance training of the hip adductors (> 1/week) in the preceding 1 month before study initiation.
- groin pain resulting in loss of one or more football matches/training sessions in the preceding 1 month prior to study initiation.
- any longstanding injury (≥ 6 weeks) in the lower extremities or in the hip/groin in the preceding 6 months prior to study initiation.
- pain of more than 2/10 on a numeric rating scale (NRS) when performing the adduction strength tests or exercises were also excluded.
- For analysis, players will be excluded if there was an adherence of less than 75% of the exercise sessions.
Ethics Ethical approval was obtained from University of West Attica ethics committee and all players will give their informed consent prior to inclusion in accordance with the Declaration of Helsinki.
Randomisation Randomisation will be performed after baseline strength testing. Participants will be individually randomized to perform either the CA or the SQ exercise protocol. The randomisation sequence will be obtained using an online software (e.g. randomizer.org), and sealed, opaque envelopes containing group allocation will be prepared by an independent person not otherwise involved in the study, and who will be unaware of the baseline strength test results. All participants will be instructed not to perform any additional adductor exercise other than their allocated exercise and to keep their regular training as usual.

盲法说明
The person performing the strength tests will be blinded to group allocation, and participants will be instructed not to reveal any information about their group allocation. In addition, the physiotherapist supervising the intervention procedures will not be allowed to know the results of the strength measurements of each player.

结局指标
主要结局
Eccentric hip adductor strength
时间窗: Change from baseline eccentric adductor strength at 8 weeks
The athlete lies on the side of the tested leg with their hip and knee in a straight position. The hip and knee of the other leg are placed in 90deg of flexion with the knee placed on a box to maintain position of the pelvis. The athlete holds on to the side of the bed with one hand for stabilization. The examiner lifts the tested leg off the bed into full adduction and applies a downward force to the limb holding the HHD 5cm above the medial, while the athlete is asked to resist that force performing hip adduction "as hard as possible" Then the tester breaks the athlete's resistance applying a downward force. The procedure is performed three times with a 30-second rest between each of them and the highest value is recorded.
次要结局
- Unilateral isometric adduction strength(Change from baseline isometric adductor strength at 8 weeks)
- Delayed onset muscle soreness(Difference in mean muscle soreness at 8 weeks)
