Abstract

The aim of this study was to compare analytical methods to quantify muscle activation and muscle fatigue in prolonged cycling. Six endurance-trained male cyclists performed a simulated 100 km time trial ,in hot (34 QC) and cool (10 QC) climates. During the time trial EMG from the vastus lateralis was measured in five 1 km sprints and variables indicative of muscle activation and muscle fatigue were measured via two different methods. The results from this study indicate that different methods of EMG analysis may change some findings in exercise-induced fatigue studies. Further, this study confirms the need for research in multi-disciplinary models of fatigue that consider biomechanical, physiological, biochemical and cognitive factors.
