Detailed explanation-1: -Improper exercise, long time combat, military training and some related diseases (for example, cancer and stroke) can cause muscle fatigue, which negatively affects athletic achievement, military combat ability and patient recovery.
Detailed explanation-2: -Muscle fatigue has a number of possible causes including impaired blood flow, ion imbalance within the muscle, nervous fatigue, loss of desire to continue, and most importantly, the accumulation of lactic acid in the muscle.
Detailed explanation-3: -The decrease in temperature also causes our blood vessels to constrict, reducing the amount of oxygen and nutrients that reach our muscles. This can lead to a decrease in muscle performance and strength, as well as increased fatigue.
Detailed explanation-4: -The temperature affects how easily oxygen is released from hemoglobin to the muscle. In colder weather, the rate that oxygen is released is slower.
