Challenges and Solutions in Muscle Activity Measurement

This chapter explores the limitations of electromyography (EMG) in measuring muscle activity during exercises, discussing factors affecting accuracy and the significance of moment-arm data. It delves into using maximal voluntary isometric contractions for quality EMG data and highlights the importance of voluntary activation for muscle force measurement. The conversation underscores the need for aligning EMG and moment-arm data to comprehensively understand muscle recruitment, touching on dynamic contractions and motor unit recruitment.
