Human body and everything that its made of, is made to perform optimally at 36.5°C
To warm
- Blood circulates and acts as an inner cooling system. blood vessels open to gift the heat to the streams. Stream reaches trough embranchement the layers where the sweatglands are. sweat is created to exchange heat with surface.
- This proces happens each time when you work out. However when its to warm, this requires additional efford and energy that isnt going to the lifting/cardio.
- To fasten it up, the heart will pump faster. This lowers the ammount your hearbeat can go up while excercising.
(normal : 70 -> 180 = it can rise 110) (now : 95 ->180 = it can rise 95)
To cold
- Muscle contraction requires optimal temperatures and acidity. Like an engine, "cold muscles" arent good because the fluids dont flow as efficient as they should, and the tissue is more rigid.
- lower flexibility of tissue can lead to injuries
- low temperature effects the carnosine working, meaning your muscles operate at a lower ph, wich will give more muscular pain and less good recovery afterwards
Id say, a powerlifter has more issues when its to warm, and a runner has much more issues when its to cold
