Area of Science:

  • Biomechanics
  • Exercise Physiology
  • Sports Science

Background:

  • Assessing the reliability of functional electromechanical dynamometry (FEMD) is crucial for its application in strength training research.
  • Understanding the test-retest reliability of FEMD-controlled squat protocols informs its use in evaluating training adaptations.

Purpose of the Study:

  • To evaluate the test-retest reliability of two distinct functional electromechanical dynamometry (FEMD)-controlled squat training protocols.
  • To determine the reliability of various performance metrics during FEMD-controlled squats at different intensities.

Main Methods:

  • Twenty-eight healthy young adults participated in four laboratory sessions.
  • Participants performed squat protocols at 75% of one-repetition maximum (1RM) for 3 sets of 12 repetitions and 50% 1RM for 3 sets of 30 repetitions.
  • Key performance variables including range of movement (ROM), mean dynamic strength (MDS), peak dynamic strength (PDS), and work (W) were recorded and analyzed for reliability using intraclass correlation coefficient (ICC) and coefficient of variation (CV).

Main Results:

  • Very high reliability (high ICC, low CV) was observed for ROM, MDS, PDS, and W at both 50% and 75% 1RM.
  • High reliability was found for other measured variables, including mean velocity (MV), peak velocity (PV), mean potency (MP), peak potency (PP), and impulse (I), across both squat protocols.
  • The results indicate consistent measurements across repeated sessions for most parameters.

Conclusions:

  • Functional electromechanical dynamometry (FEMD) is a reliable tool for assessing a comprehensive set of performance variables during squat exercises.
  • The findings support the use of FEMD in both 50% and 75% 1RM squat protocols for reliable measurement in healthy young adults.
  • FEMD provides consistent and dependable data for evaluating strength and movement characteristics in exercise science research.
