Water and Electrolyte Balance in Elementary and Secondary Physical Education Students in a Hot Environment
LANGUAGE NOTE | Document text in Chinese; abstract also in English.
The present paper discusses the physiological and biochemical changes in elementary and secondary school students participating in physical activities in a hot environment. In addition the paper will evaluate the characteristics of water and inorganic electrolyte loss. There were very large differences in cardiovascular function, metabolism, perspiration and body temperature regulation between elementary and secondary school students, when exercising in a hot ambient environment. With this knowledge it is important that physical education classes be carefully developed, relative to duration and exercise intensity, when students are expected to be exposed to high ambient temperatures. Students should be encouraged to consume fluids, before, during and following exercise classes. Fluid replacement beverages should contain 6% carbohydrate and 18mMol/L of sodium.
