Background and Objective: The present research aimed to determine the effect of a period of high-intensity interval training (HIIT) on serum levels of parathormone, alkaline phosphatase, and bone mineral in postmenopausal women.
Materials and Methods: In a semi-experimental research, 24 sedentary postmenopausal women were randomly divided into control (n=12) and training (n=12) groups. The training group performed HIIT, 3 sessions per week for 8 weeks. 24 hours before the experimental period and 48 hours after the last training session, the subjects' anthropometric characteristics, including height, weight, skeletal muscle mass (SMM), body fat mass (BFM), body fat percent (BF%), body mass index (BMI), waist-to-hip ratio (WHR), and serum levels of parathyroid hormone, alkaline phosphatase, phosphorus, and calcium were measured. To compare the mean of two groups at two times, two-way repeated measures analysis of variance was used.
Results: There was no significant difference between the weight and BMI of the two groups at two times (P>0.05), but there was a significant difference between the SMM, BFM, BF%, and WHR (P<0.05), so SMM of the training group increased significantly compared to the control group and BFM, BF%, and WHR decreased significantly (P<0.05). Also, there was a significant difference between serum levels of parathormone, alkaline phosphatase, phosphorus, and calcium of the two groups at two times (P<0.05), so these variables in the training group increased compared to the control group (P<0.05).
Conclusion: A period of HIIT with improving anthropometric characteristics can have a positive effect on serum levels of parathormone, alkaline phosphatase, and bone mineral in postmenopausal women.
