Fatigue is a complex phenomenon with multiple contributing factors. While glycogen depletion is a significant factor, others include:
Decreased Blood pH (A): Lactic acid buildup during intense exercise can lower blood pH, leading to acidosis and fatigue.
Lactic Acid Accumulation (B): High levels of lactic acid can interfere with muscle contraction and contribute to fatigue.
Oxygen Depletion (C): Insufficient oxygen supply to muscles can limit energy production and lead to fatigue.
Dehydration (E): Dehydration can reduce blood volume and impair blood flow to muscles, limiting oxygen delivery and waste removal.
Muscular Tension (D): While muscular tension can contribute to fatigue, it is not as direct a factor as the other options.
