Body Heat and Sporting Activity

Date: 02/07/2020 | Source: Sports DPRK (En) | Read original version at source

Man consumes certain amount of energy every day, 20-30% of which is used for movement of muscles and remnant turns into heat to provide body temperature.

When doing exercise, heat production increases in muscles, and as a result body temperature also climbs 1℃ more than usual one minute later.

This improves flexibility of muscles as well as metabolism.

It also enhances the capacity of blood to carry oxygen and expands peripheral vessels, promoting supply of oxygen and nutrients, and excretion of waste materials.

As it is a good physiological condition for sports, it is advisable to raise temperature by warming up before training and competition.

It is more essential in cold weather.

Such artificial thermal stimulation as hot water shower also brings good effect without any warming up.

Playing matches without warming up in 800- and 1500-m races, football, basketball and other sports events raises body temperature too much, which may cause negative results.
