Acute Responses and Chronic Adaptions
RESPONSE 1 : Sweating Sweating is a part of puberty. Sweating helps maintain body temperature by cooling us down. Our body heats up because our muscles are working harder and our blood circulates faster.
Response 2 : Heavy Breathing
Our breathing rate increases because our muscles need more oxygen as they are working harder and faster, so they require more air to keep them going. Breathing heavier during exercise also rids the body of carbon dioxide.
Adaption 1 : A bigger heart
With exercise, the heart increases in size. Athlete's hearts can be one third larger than an average heart because their muscle fibres are thicker. Having a bigger heart can effect your body, making you healthier and stronger.
Adaption 2 : Our Blood
More red blood cells are produced, which allow the blood to transport more oxygen to the muscles, so the muscles can grow and we have more blood circulating the body on a regular basis, especially when exercising.
Adaption 3 : Our Lungs
With training, the total volume (the amount of air that we breathe in and out) increases, also the alveoli further develops which allows for more to go in exhange.
