Summary Introduction

To determine: The appropriate hypothesis regarding the cause of muscle fatigue, as shown in the graph given in the book.

Introduction: Muscle fatigue is a medical condition that is characterized by the decrease in the performance of muscles observed after a period of intense physical activity. It depends on various factors. This condition reduces the performance of an individual during exercise and playing sports. It is caused by the failure to generate and maintain power. In the experiment, four metabolites were tested for their role in causing muscle fatigue. The four metabolites were ATP, lactate, phosphocreatine (PCr), and creatine(Cr). The presence of these metabolites was measured before at rest and then after cycling. The results were represented in the form of a graph.
