The purpose of this study was to investigate the effect of eight weeks of high intensity interval training (hiit) on osteopontin and some bone mineral indexes (calcium, phosphorus, magnesium, iron) on active young women. Materials and methods: in this semi-experimental study, 16 active women were selected and divided into two groups: hiit with mean age 22.2±1.2 years, height 162.8±6 cm, weight 57.6± 9 kg, and control with average age of 22.3±4 years, height 156.2±4 cm, and weight 54.6±7 kg. Running- based anaerobic sprint test (rast) with a 3-minute break-in interval, which was added every two weeks. Blood samples of participants were taken before and after the protocol, data were analyzed using independent t-test (p≤0.05) was analyzed. Results: the results showed a statistically significant difference between the two groups in the osteopontin index (p = 0.0001). The results also showed that there was no significant difference between calcium (p =0.259), magnesium (p =0.19), fe (p =0.883) and phosphorus (p =0.153) in the young women of the two research groups. Conclusion: the results of this study showed that the implementation of 8 weeks hiit exercises improved bone mineral density.
