The body reacts more during exercise because increased muscle contraction requires more energy, leading to increased cell respiration and a greater need for oxygen.
El cuerpo reacciona más durante el ejercicio porque el aumento de la contracción muscular requiere más energía, lo que aumenta la respiración celular y la necesidad de oxígeno adicional.
| Front | Why does the body react more during exercise? |
|---|---|
| Back | This is because when you exercise, some of your muscles contract more frequently than normal so you need more energy, which comes from increased respiration, the increase in respiration in cells means you need to get more oxygen into them. |
