at high temperatures, metabolites accumulate in activated muscle fibers thus reducing endurance. at low temperatures neuromuscular electrical transmission of the contractile properties of the muscle may lead to fatigue
There are several substances and mechanisms that cause muscle pain. The most common are immediate onset and delayed onset pain. Immediate onset pain is caused by muscle fatigue which comes from exercise of physical activity and occurs when the muscle has rerached its conditioned fatigue point. Delayed onset pain occurs 24-48 hours after the muscles have been worked to their fatigue point and are rebuilding themselves. This is the muscle soreness that many people experience when they start a new exercise program.
Lactic acid builds up and causes muscle burn.

Sudden pain that occurs in the calf muscle during activity may be the result of a pulled or torn calf muscle. This is called a calf strain or a calf pull. It occurs when part of the muscles of the lower leg (gastrocnemius or soleus) are stretched beyond their ability to withstand the tension. This stretching can result in small microtears to the muscle fibers or, in a severe injury, a complete rupture of the muscle fibers.
Muscle Fatique occurs when low o2 conditions deplete Atp and cp stores acaerobic respiration creates lactic acid. drops in ph and o2 debt lead to failure of the muscle to maintaain contractions

Not sure but I think this person may be looking for the gastrocnemius muscle it is situated in the calf of your leg Sudden pain that occurs in the calf muscle during activity may be the result of a pulled or torn calf muscle. This is called a calf strain or a calf pull. It occurs when part of the muscles of the lower leg (gastrocnemius or soleus) are stretched beyond their ability to withstand the tension. This stretching can result in small microtears to the muscle fibers or, in a severe injury, a complete rupture of the muscle fibers, and when this happens you will be in no doubt due to the pain
