Strenuous activities demand more energy because they involve increased muscle work, higher metabolic rates, and greater expenditure of stored energy reserves to sustain prolonged physical effort.
Strenuous activities require more energy due to increased metabolic demands and heightened physiological efforts. Engaging in strenuous physical exertion, such as running or lifting heavy weights, demands a rapid and substantial energy supply to fuel muscle contractions, maintain body temperature, and support elevated heart and respiratory rates. The body’s energy requirements escalate to meet the heightened oxygen and nutrient needs for efficient cellular respiration. This metabolic response ensures an adequate supply of adenosine triphosphate (ATP), the energy currency of cells, to sustain the intensified physical effort and prevent fatigue. Thus, greater energy consumption is essential to meet the elevated demands imposed by strenuous activities.
