Abstract Background: Moderate intensity continuous training (MICT) has been reported as an effective exercise on bone metabolism. However, very few studies have focused on high-intensity interval training (HIIT). The aim of this study was to investigate and compare the effects of HIIT and MICT training on bone density in middle-aged rats.Methods: 30 male Wistar rats (16 weeks old) were randomly divided into three groups: control, MICT and HIIT. Both test groups completed 8 weeks (5 sessions per week) of treadmill training in which the HIIT group performed 10 sessions of running at a speed of 35-47 m/min with a 2-minute active recovery, and the HIIT group ran continuously for 10-45 minutes at a speed of 15-20 meters per minute. The body composition and bone mineral density in the whole body were evaluated through Dual Xray absorptiometry (DXA) at the beginning and after the intervention. The data was analyzed using SPSS software and one-way analysis of variance and Tukey's post hoc tests.Results: After 8 weeks of intervention, BMD of the whole body and femur increased significantly in both groups (p0≥0.05), although the observed change was greater in the HIIT group (p≥0.05). In addition, in the case of BMD of the lumbar vertebra, no significant difference was observed between all three groups after the intervention (p≤0.05).Conclusion: These findings show that a period of HIIT and MICT training can improve bone density in middle-aged rats and compared to MICT, HIIT had more benefits on bone density.

Background: To improve the education of orthopaedic residents and enhance patient care in the Iran's healthcare system, it is necessary to gather information about the current status of scientific, practical, and research-based education for residents.Methods: The research project initially focused on examining the executive curriculum in 14 centers affiliated with 6 different medical universities. Subsequently, an investigation was conducted into human resources, infrastructure, operating room facilities, educational and research outcomes, as well as the regular implementation of practical examinations to evaluate the performance of residents during their residency years. All the aforementioned aspects were covered using a comprehensive questionnaire, which was distributed via the "Formafzar.com" website as a link to the heads of departments in these centers by the Iranian Orthopaedic Association. The relationship between facilities and equipment and passing the future specialized orthopaedic board examination was also evaluated.Results: Among the examined centers, only 20% adhered to the criteria of Iran educational curriculum in all aspects of human resources, education, and research.Conclusion: a regular evaluation of teaching methods used by international centers and the national curriculum is necessary for orthopaedic training centers in Iran. Additionally, regulatory systems should monitor the training process of orthopaedic residents to standardize services, equipment, and educational programs in the country.
