Many high-level athletes do “cool downs” which consist of slowing down their actions, breathing deeply, and eating a snack. Why does this speed up their recovery process after an intense workout?
Breathing deeply they release more carbon dioxide which leads to more energy for cellular respiration to begin.
Cooling down in this way they are able to take in oxygen and sugar which allows their cells to produce energy through cellular respiration.
Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration.
When eating a snack, they take in energy which converts to sugar needed by the body to produce oxygen for the athletes muscles to begin cellular respiration.
