Effect of high intensity interval training on hormonal factor affecting bone metabolism

High interval training changes the bone metabolism. The present study was aimed at investigating the effect of High Intensity Interval Training (HIIT) on biochemical factor of adult male Wistar rat. In this semi-experimentral studu sixteen male Wistar rats aged 6 weeks old with weight of 250±20 g were divided into control (n=8) and experimental groups (n=8). After a week of orientation training protocol، eight weeks of incremental HIIT training program was followed. 24 hours after the last training session، anesthesia and sacrificed blood samples were taken directly from the animal''s heart. Serum PTH and ALP were determined with RAI (Imonotopic CA kit)، kinetic (Pars azmon kit)، Ca and P were determined with Arsenazo، Phosphomolydate and independent t-test was used for statistical analysis. The result indicated that the level of PTH and ALP increased significantly whereas calcium and phosphate of experimental group did not show significant rise. High intense interval training، possibly through increased PTH and protein factors، control bone mass density and volume and thus effecting bone metabolism.
