Background: Functional movements involving hip extension and lumbo-pelvic stabilization are important for individuals with non-specific low back pain (NSLBP). Although bridge and sling bridge exercises are commonly used to improve these functions, comparative evidence on their effects, particularly in terms of muscle activity, rating of perceived exertion (RPE), and heart rate variability (HRV), remains limited. Purpose: This study was conducted to compare the electromyographic activity of the gluteus maximus (GM), biceps femoris (BF), and multifidus (MF), as well as rating of perceived exertion and heart rate variability, during bridge and sling bridge exercises in individuals with non-specific low back pain. Study design: Cross-sectional design Methods: Twenty male participants with non-specific low back pain (NSLBP) performed bridge and sling bridge exercises in a randomized order. Muscle activity of the gluteus maximus (GM), biceps femoris (BF), and multifidus (MF) was measured using electromyography and recorded for 5 seconds after achieving the final exercise posture. Heart rate variability (HRV) was assessed using the Apple Watch Series 7 before and immediately after each exercise, while the rating of perceived exertion (RPE) was measured immediately after each exercise. Data were analyzed using paired t-tests (α = 0.05). Results: As a result of comparing the bridge exercise and the sling bridge exercise, the muscle activity of the GM, BF, and MF and HRV were significantly higher during the sling bridge exercise compared to the bridge exercise (p<0.05). However, the GM/BF and MF/BF ratios were significantly higher during the bridge exercise (p<0.05). While no significant difference was found in the RPE between both exercises. Conclusions: In the early stages of rehabilitation, bridge exercises should be prioritized to selectively activate the GM. In the later stages of rehabilitation for individuals with NSLBP, sling bridge exercises are recommended, as overall activation of various lower extremity muscles and HRV is necessary.
