Isometric Abdominal and Specific Gluteus Medius Work in Soccer Players (COREGLUTFEM)

Isometric Abdominal and Specific Gluteus Medius Work in Soccer Players. A Randomized Pilot Study

The problems of lack of lumbo-pelvic stability, as well as weakness or mobile restriction of the adductor muscles, may be the origin of lower limb injuries. Both intrinsic and extrinsic factors are key in the probability of suffering an imbalance. A protocol of abdominal isometric strength, accompanied by specific exercises of the gluteus medius, can be useful in order to prevent such dysfunctions.

The objective is to compare the efficacy of abdominal isometric work against the specific work of gluteus medius in the improvement of lumbo-pelvic stability and strength and elasticity of the adductor muscles.

Study design. Randomized, longitudinal, experimental, prospective, multicentre and single-blind clinical trial. It will take place at the facilities of the Soccer Club Fuenlabrada S. A. D. and the European University of Madrid.

The subjects will be randomly divided into two groups: control group and experimental group. The intervention period will last eight weeks, performing 2 weekly sessions, of approximately 20 minutes (depending on the group to which each subject belongs). The variables to be evaluated before and after the intervention will be the lumbo-pelvic stability and the strength and elasticity of the adductor muscles. For the statistical analysis, the SPSS program version 19.0 will be used.

It is expected to find how gluteal work produces improvements in lumbo-pelvic stability, as well as an increase in strength and adduction elasticity.

Study Overview

• Status: Completed
• Conditions: Young Soccer Players
• Intervention / Treatment: Other: Experimental group; Other: Control group

Detailed Description

Each session will last 20 minutes, taking place during 2 days a week, in a period of 8 weeks. The intervention will be carried out at the beginning of the training session. This intervention consists of an abdominal work protocol, and a gluteal work protocol added to the previous protocol, performed by the control group and the experimental group, respectively.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline lumbo-pelvic stability after treatment and at 1 month	With a universal goniometer, the subject slightly lowers the extended legs, and the moment the lumbar spine loses contact with the ground, the angle is measured whose legs form with the ground	Screening visit, within the first seven days after treatment and after one month follow-up visit

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline elasticity of the adductor muscles after treatment and at 1 month	With the subject sitting on the floor, and both legs extended and separated as much as possible, passively, place the goniometer with the axis parallel to the floor at the level of the pubic symphysis and both arms moving along the axis of the femur. The normative values: the normal range is from 0º to 180º	Screening visit, within the first seven days after treatment and after one month follow-up visit
Change from baseline adductor muscle strength after treatment and at 1 month	With a manual dynamometer, hooked to a fixed point and perpendicular and lateral to the leg to be treated, at the height of the distal third of the tibia, and the subject standing, the subject had to perform a hip adduction, generating a Progressive maximum isometric contraction.	Screening visit, within the first seven days after treatment and after one month follow-up visit
