Relationship Between the Functional Movement Screen and Isokinetic Muscle Strength of Knee in Different Sport Branches

This study was conducted to demonstrate the correlation between the functional movement screen and the isokinetic muscle strength with objective data. Investigators conclude that the use of FMS in combination with isokinetic systems will provide more detailed information on the prevention of injuries to sports and the improvement of performance.

About this study

This study was conducted to demonstrate the correlation between the functional movement screen and the isokinetic muscle strength with objective data. 60 athletes involved in volleyball, greco-roman, speed skating, athletics and taekwondo branches were included in the study. The functional movement of the athletes was assessed by Functional Movement Screening, lower extremity isokinetic muscle strength was assessed by ISOMED 2000® isokinetic device.

Treatment and study plan

Functional Movement Screen (FMS)

Other

FMS is an analysis system that evaluates muscle strength imbalance and functional performances on the dominant-non-dominant side in athletes. It aims to detect stability and mobility that can be ignored in the asymptomatic active population and athletes. It consists of 7 basic parameters determined by Gray Cook (Deep Squat, Hurdle Step, -In-line Lunge, Shoulder Mobility, Active Straight Leg Raise, Trunk Stability, Rotatory Stability). The athletes were evaluated after giving verbal instructions to the athletes about the head, trunk, knee and foot positions. For each parameter, the athletes were given points between 0-3 values. The total score was determined as 21 points. Completing the movement completely and without compensation was given 3 points, and 2 or 1 points were given according to the activation of the compensation mechanism and balance disorders. In case of any pain during or at the end of the movement in the evaluated parameter, 0 points were given to the athletes.

Isokinetic Muscle Evulation of Knee Muscles

Other

The isokinetic knee flexor and extensor group muscle strengths of the athletes participating in the study were measured on the dominant and non-dominant sides. Measurements were performed with an ISOMED 2000 (D&R Ferstl GmbH, Hemau, Germany) isokinetic measuring device. The test protocol was adjusted to be concentric/concentric. Measurements were made at angular velocities of 60°/sec and 180°/sec. At an angular speed of 60°/sec, the athlete was asked to perform 10 repetitions of voluntary knee flexion/extension at maximum strength. Then, after resting for 30 seconds, 30 repetitions of knee flexion/extension were performed at an angular velocity of 180°/sec. Before starting the test in both angular speeds, 3 repetitive attempts were made to learn the movement. The following parameters were evaluated at 60°/sec and 180°/sec angular speed.
