Abstract:

BACKGROUND: Based on the blood and urine biochemical changes in different intensities and types of exercise, this research describes the impact of exercise on bone metabolism. Meantime, these biochemical indexes also show a method of marking physiological differences of certain individuals, and also reflect the impact of exercise on bone. These can be regarded as a monitoring index of bone growth and metabolism.

OBJECTIVE: To study exercise effect from the biochemical indicators in bone metebolism, and make a further discussion about its influence on bone formation and bone resorption.
METHODS: Databases of CNKI and PubMed were retrieved by computer with key words of “exercise; bone metabolism; biochemical indicators” in Chinese and English, respectively, by screening titles and abstracts to search papers related to exercise effects on the blood and urine biochemical indicators. Totally 236 papers were initially found, and only 38 papers were included in result analysis.
RESULTS AND CONCLUSION: Low-intensity exercise shows less effect on the bone, but excessive exercise is harmful to the bone that can cause stress fractures. What’s worse, it causes a lack of female hormone and reduce bone mass. Exercise can alter the blood and urine biochemical indicators in aspects of types of exercise and intensities. Only the exercise at appropriate intensity makes positive effects on bone formation and resorption, and assists bone mineral density and bone biomechanical indicators to develop exercise prescription and arrange rehabilitation exercises. MechanismS of bone turnover need further discussion at the cellular level.
