  • Research summary

    Relative Energy Deficiency in Sport (RED-S) syndrome is considered a serious medical condition that can result in negative long-term health and performance consequences. Currently, the International Olympic Committee (IOC) RED-S Clinical Assessment Tool and the Safe Exercise at Every Stage guidance are used by clinicians to inform decision-making during return to training following RED-S. It has been highlighted by the IOC that research is required to establish the efficacy of specific recommendations to improve long-term recovery outcomes after RED-S. Targeting musculoskeletal-related adaptations during early-phase recovery from RED-S is a recommended strategy to mitigate against future injury and maximise return to performance outcomes, yet empirical evidence is currently lacking. The purpose of this study is to examine the effect of strength training on muscular strength, muscle morphology, and markers of bone health in endurance athletes recovering from RED-S. The study will also explore the experiences and perceptions of participants following the intervention.

    The study will employ a mixed methods case-control design. A minimum of eight endurance athletes recovering from RED-S (age 16-35 years) will be required to take part. Healthy age- and sport-matched participants will also be recruited as a control group. Initially, all participants will undergo magnetic resonance imaging, dual x-ray absorptiometry, and peripheral quantitative computed tomography scans, and strength testing. Participants will also complete validated questionnaires to assess exercise psychopathology, wellbeing, and eating behaviours. A strength training intervention will then be delivered to the RED-S athletes 3 x per week for six months. Following the intervention, participants will be re-tested using identical protocols to those at baseline. Semi-structured interviews will also be used with RED-S participants to explore perceived benefits, barriers, and challenges of the intervention.
