Verified step by step guidance

Understand the concept of muscle fatigue: Muscle fatigue occurs when a muscle loses its ability to contract effectively, often due to prolonged activity.

Identify common factors contributing to muscle fatigue: These typically include accumulation of lactic acid, ionic imbalances, and depletion of ATP.

Analyze each option: Consider how each factor affects muscle function. Accumulation of lactic acid can lower pH and affect enzyme activity. Ionic imbalances can disrupt electrical signals needed for muscle contraction. Depletion of ATP limits energy available for muscle contractions.

Evaluate the option 'Increased oxygen supply': Increased oxygen supply generally helps in reducing muscle fatigue by enhancing aerobic respiration, thus providing more ATP and reducing lactic acid buildup.

Conclude which factor does not contribute to muscle fatigue: Since increased oxygen supply aids in muscle recovery and performance, it is not a factor that contributes to muscle fatigue.
