Introduction: Although many forms of exercise are known to have positive effects on bone metabolism in postmenopausal women, the effect of high-intensity interval training (HIIT) has not been investigated in this setting. This study aimed to evaluate the impact of the 6-week HIIT program on body composition, biochemical parameters, and bone turnover markers in overweight and obese postmenopausal women. Methods: A total of 32 postmenopausal women were randomly assigned to exercise (n=15) or control (n=17) groups. The blood samples and body composition were analyzed. The exercise group participated in a 6-week stationary bike HIIT exercise [(3 days/week; 30 sec work-90 sec resting intervals with 90-95% of the heart rate reserve-12 to 16 min/day)]. The control group was not involved in any exercise program. Results: In the exercise group, significant reductions were noted in waist and hip circumference, low-density lipoprotein, total cholesterol, triglycerides, phosphorus, calcium, albumin, bone-specific alkaline phosphatase, type 1 collagen C-terminal telopeptide, and osteocalcin levels, in addition to significant increases in high-density lipoprotein, free thyroxine, thyroid-stimulating hormone, vitamin D (25-hidroksi vitamin D), and cortisol levels, when compared with the control group (p
