When muscles work harder, they require increased energy, which is primarily derived from adenosine triphosphate (ATP). This demand is met through enhanced oxygen supply and nutrients, particularly glucose and fatty acids, to support aerobic and anaerobic metabolism. Additionally, proper hydration and electrolytes are crucial for muscle contraction and overall performance. Adequate rest and recovery are also essential to replenish energy stores and repair muscle tissue.
