Low-Load Rehabilitation Strategies in Sports Injury Recovery: From Blood Flow Restriction to Hypoxic Training

Rehabilitation science increasingly emphasizes interventions that optimize recovery while minimizing mechanical stress on healing tissues. Traditional high-load training, though effective in restoring strength and function, often cannot be safely applied in the early stages of rehabilitation. This has prompted growing interest in low-load strategies, such as blood flow restriction (BFR) and hypoxic training, which aim to maintain muscle mass, neuromuscular performance, and cardiovascular conditioning under reduced mechanical demands. Recent studies have demonstrated that these interventions can trigger comparable anabolic and functional adaptations to high-intensity protocols through metabolic stress, hormonal signaling, and neuromuscular activation. Yet, despite promising findings, there remain important gaps in understanding their physiological underpinnings, safety considerations, and long-term effects across diverse athlete populations and injury profiles.This Research Topic aims to advance the understanding and application of low-load rehabilitation methods in sports injury recovery. The main objective is to consolidate current knowledge on how blood flow restriction and hypoxic interventions contribute to tissue repair, performance reconditioning, and functional reintegration after injury. Core questions include the mechanisms driving adaptation under reduced load conditions, how individual physiological responses differ across training modalities, and what evidence-based frameworks can optimize recovery, minimize reinjury risk, and improve return-to-sport outcomes. Contributors are encouraged to explore the translation of laboratory insights into clinical and field practice across varying sports settings.Covering a broad but clearly defined scope, this Research Topic focuses on rehabilitation strategies that reduce mechanical loading while sustaining or enhancing recovery outcomes.To gather further insights in athletic rehabilitation and clinical exercise science, we welcome articles addressing, but not limited to, the following themes:o Physiological and molecular mechanisms underlying blood flow restriction and hypoxic trainingo Comparative effects of low-load versus traditional high-load rehabilitation on muscle recovery and strength adaptationo Applications of low-load methods in musculoskeletal injury rehabilitation and return-to-play scenarioso Monitoring recovery and readiness through biomarkers, imaging, and neuromuscular assessmento Practical guidelines for implementing safe and effective low-load interventions in athletes and active individualso Technological or methodological innovations supporting precision rehabilitation approachesAccepted article types may include original research, systematic reviews, meta-analyses, brief reports, and perspectives.
