Exercise training for bone and lipid metabolisms: exercise intensity and duration are important factors / 中国组织工程研究

ABSTRACT

BACKGROUND: Rational exercise training promotes bone and lipid metabolisms, while over-trained exercise makes negative effect. There are many biomarkers and pathways in the progress of bone and lipid metabolisms, which have been explored in different suitable studies. OBJECTIVE: To summarize the indexes and pathways of bone and lipid metabolisms, especially the common biomarkers and pathways, and to explore the effects of exercise on bone and lipid metabolisms. METHODS: PubMed and CNKI databases were retrieved with the keywords of "exercise training, bone metabolism, lipid metabolism, index, pathway" in English and Chinese, respectively. Finally, 52 eligible articles were enrolled for result analysis. RESULTS AND CONCLUSION: Bone metabolic indexes include 25-hydroxy-vitamin-D, calcitonin, parathyroid hormone, tumor necrosis factor, interleukin 1, 2, 4, 6 and 11, insulin-like growth factor 1, transforming growth factor-beta, bone morphogenetic protein, interferon, macrophage colony-stimulating factor, fibroblast growth factor, platelet fireworks growth factor, tartrate-resistant acid phosphatase, collagen Ⅰ telopeptide, pyridinoline, urinary deoxypyridinoline, alkaline phosphatase, osteocalcin, osteoporogeterin, carboxyterminal propeptide of type Ⅰ procollagen and so on. While lipid metabolic indexes contain triacylglycerol, serum total cholesterol, high density lipoprotein, low density lipoprotein, leptin, adiponectin, apolipoprotein, oxidized low density lipoprotein, and low density lipoprotein receptor related protein. Exercise intensity and duration are important factors for bone and lipid metabolisms. While a long-term high-intensity exercise will do harm to bone and lipid metabolisms, and a short-time high-intensity exercise is beneficial for bone metabolism. The interaction of exercise intensity and duration on bone and lipid metabolisms still needs to be further studied.
