ABSTRACT

Aim: This study aims to recommend an optimal maximal voluntary isometric contraction protocol that will not cause muscle fatigue

Methods: Cross-sectional study design was conducted to measure the maximum torque values obtained during 10s self-paced gradually increasing force in 10 repetitions of maximum voluntary isometric contractions (MVICs). During the measurements, neuromuscular activity of biceps femoris (BF), gastrocnemius medialis (GM), rectus femoris (RF), vastus lateralis (VL), and vastus medialis (VM) muscles were recorded.

Results: In line with the results, intraclass correlation coefficient values in the range of 0.726-0.903 were found for all variables.

Conclusion: The maximum voluntary isometric contraction protocol proposed by the research gives consistent results between measurements.
