Effect of improving asymmetry through self-myofascial release in adolescent soccer player with hypomobility syndrome hip: A randomized controlled trial.

Background: Hypomobility syndrome (HMS), or limited hip range of motion (ROM), is often reported in adolescents who train heavily. This study was aimed to investigate the impact of traditional static stretching (STR) and self-myofascial release (MFR) in adolescents with HMS hip.

Methods: This study was a randomized controlled trial.

Aerobic and Anaerobic Fitness according to High-Intensity Interval Training Frequency in Youth Soccer Players in the Last Stage of Rehabilitation.

In the last stage of rehabilitation, high-intensity interval training (HIIT) for improving physical fitness is appropriate for return-to-play; however, some youth athletes visit the rehabilitation center less frequently due to conflict with their distance to center, and academic schedule. We tested the effects of short-term low-frequency HIIT in 54 youth male soccer players, after dividing them into a low-frequency group (LFG, = 27 players) and a high-frequency group (HFG, = 27 players). Muscle mass and body fat were measured using a body composition test, and VOpeak and exercise duration were measured using a treadmill.
