Instantaneous Frequency based Study of the Effects of Physical Training on Muscle Fiber Recruitment Strategy

The paper explores the application of instantaneous frequency (IF) analysis on EMG signals measured voluntarily across a period of 10 week physical training. The aim is to explore the effects of training on the muscle fiber recruitment strategy. The findings are presented and discussed, which suggest a link between training and motor unit synchronization. The paper also show-cases the effectiveness of IF methods for EMG data analysis.
