Summary
Functional electromechanical dynamometers (FEMD) reliably measure hamstring strength in soccer players during swing eccentric hamstring exercises (SEHE). This device is effective for assessing eccentric strength in athletes.
Area of Science:
- Sports Science
- Biomechanics
- Exercise Physiology
Background:
- Functional electromechanical dynamometers (FEMD) are proposed for evaluating movement patterns.
- Assessing the reliability of FEMD for specific exercises is crucial for its application.
Purpose of the Study:
- To determine the reliability of FEMD for swing eccentric hamstring exercise (SEHE) measures in soccer players.
Main Methods:
- Nineteen male soccer players performed SEHE at 20, 40, and 60 cm/s.
- Measurements were taken across four sessions, including familiarization and registration.
- Average and maximum load were calculated using FEMD (Dynasystem®).
Main Results:
- High reliability was observed for average load at 40 cm/s (ICC=0.94).
- Maximum load demonstrated high reliability at 20 cm/s (ICC=0.91-0.87).
- Maximum load exhibited the most consistent reliability.
Conclusions:
- The FEMD (Dynasystem®) is a reliable tool for assessing hamstring eccentric strength in soccer players.
- This finding supports the use of FEMD in evaluating athletic performance and injury prevention.
