A total of 18 articles were included in the current systematic review. The resurfacing hip arthroplasty group exhibited faster functional recovery after surgery compared to total hip arthroplasty by improving the hip range of motions, peak vertical ground reaction force, and peak hip abduction moment. Evaluation of the biomechanical changes during stair negotiation and sit-to-stand transfers is further needed to evaluate comprehensive aspects of functional ability. The findings of this review provide a comprehensive overview and help to understand the biomechanical changes for patients with total hip arthroplasty vs. resurfacing hip arthroplasty during daily activities.

Subgroup analysis suggested that SIT with shorter work durations (less than 10s) was more effective in obesity control. In conclusion, both HIIT and SIT demonstrated similar effectiveness in improving body adiposity.

This review aims to synthesize existing research on hip adductor strength testing, highlighting the importance of developing clear guidelines for its implementation. This review covers various aspects of the test, including pre-test warm-up protocols, body positioning, device placement, test execution, verbal commands, data collection and selection, and timing of tests. Key findings suggest that standardized warm-up routines, consistent body and device positioning, clear verbal commands, and specific criteria for invalidating test trials are critical for enhancing the reliability and accuracy of the test. Furthermore, consistent timing and the documentation of test conditions are essential for effective athlete monitoring and injury prevention.
