In the last decade, there has been greater appreciation of the harmful consequences of Relative Energy Deficiency in Sport (RED-S), particularly in adolescent female athletes. Coaches act as both important moderators in the development of the condition and as identifiers of athletes at risk. Research suggests that coaches lack knowledge on this topic. At present, it is unclear if RED-S education is incorporated into coach accreditation pathways. The aim of this scoping review was to describe the extent to which RED-S education is incorporated into the coach accreditation pathways of endurance sporting organizations. Five national sporting organizations (Cycling Australia, Athletics Australia, Swimming Australia, Triathlon Australia, and Rowing Australia) were contacted to participate. First, each sporting organization’s website was scoped, then semi-structured interviews were conducted online. One investigator transcribed each interview verbatim. Transcripts were analyzed for thematic content. Four of the sporting organizations provided little to no RED-S education. Rowing Australia delivered a program of RED-S content via an affiliated sports dietitian. The barriers identified for implementation of RED-S content were: limited time, resources, and coaches’ preexisting knowledge and beliefs. Based on these results, RED-S education is, indeed, lacking in some coach accreditation programs for endurance-based sporting organizations. Support for these organizations is required to overcome existing barriers and to facilitate inclusion of RED-S education within the coaching curriculum to support female athlete health.

In team sports, it has been found that team mistakes were reported as a stressor by both males and females, and at every playing level (e.g., club, university, national). The purpose of this study was to examine the impact of partners’ play on performance, emotions, and coping of doubles racquet sport athletes. Seventeen one-on-one semistructured interviews were conducted over the course of 6 months. Inductive and deductive analysis produced the main themes of overall impact on performance (i.e., positive, negative, or no impact), negative emotions (i.e., anger), positive emotions (i.e., excitement), emotion-focused coping (i.e., acceptance), and problem-focused coping (i.e., team strategy). These athletes acknowledge that how their partner plays significantly affects not only their emotions but also their own play and their choice of coping strategies. Future research should try to understand which forms of coping reduce the impact of partners’ play.

Purpose: To compare the accuracy and precision of a hip-worn accelerometer to predict energy cost during structured activities across motor performance and disease conditions. Methods: 118 adults self-identifying as healthy (n = 44) and those with arthritis (n = 23), multiple sclerosis (n = 18), Parkinson’s disease (n = 17), and stroke (n = 18) underwent measures of motor performance and were categorized into groups: Group 1, usual; Group 2, moderate impairment; and Group 3, severe impairment. The participants completed structured activities while wearing an accelerometer and a portable metabolic measurement system. Accelerometer-predicted energy cost (metabolic equivalent of tasks [METs]) were compared with measured METs and evaluated across functional impairment and disease conditions. Statistical significance was assessed using linear mixed effect models and Bayesian information criteria to assess model fit. Results: All activities’ accelerometer counts per minute (CPM) were 29.5–72.6% less for those with disease compared with those who were healthy. The predicted MET bias was similar across disease, −0.49 (−0.71, −0.27) for arthritis, −0.38 (−0.53, −0.22) for healthy, −0.44 (−0.68, −0.20) for MS, −0.34 (−0.58, −0.09) for Parkinson’s, and −0.30 (−0.54, −0.06) for stroke. For functional impairment, there was a graded reduction in CPM for all activities: Group 1, 1,215 CPM (1,129, 1,301); Group 2, 789 CPM (695, 884); and Group 3, 343 CPM (220, 466). The predicted MET bias revealed similar results across the Group 1, −0.37 METs (−0.52, −0.23); Group 2, −0.44 METs (−0.60, −0.28); and Group 3, −0.33 METs (−0.55, −0.13). The Bayesian information criteria showed a better model fit for functional impairment compared with disease condition. Conclusion: Using functionality to improve accelerometer calibration could decrease variability and warrants further exploration to improve accelerometer prediction of physical activity.
