Relative Energy Deficiency in Sport (RED-S), a potential consequence of low energy availability (LEA) can impact athletic health and performance. Bone health, growth and development can be adversely impacted. The 2023 International Olympic Committee Consensus Statement on RED-S recommends assessment for impairment of bone health, growth and development with DXA scanning and measurement of growth hormone (GH) and insulin-like growth factor 1(IGF-1). We aim to investigate if elite female Gaelic Athletic Association (GAA) players are at risk of RED-S using bone health and growth and development markers. We recruited 44 intercounty GAA players, who underwent extensive blood testing panels including the following: bone profile, 25-hydroxyvitamin D, parathyroid hormone (PTH), GH, IGF-1 and bone turnover markers. Thirty players had DXA scans to assess bone density. These have been completed pre-season to assess the baseline levels and will be repeated mid-season and end-season to evaluate the impact of intense training. Preliminary results from our study include the following. All 30 participants who underwent a DXA scan had normal bone density, with an average T score of 1.1 (17 participants > 20 years old) and average Z score of 0.9 (13 participants < 20 years old). Bone profile and PTH for the 44 participants were within the appropriate reference intervals. 12 (27%) participants were vitamin D insufficient (25-50 nmol/l). The mean GH was 274ng/ml (range 178-362) and IGF-1 was 5.02 ng/ml (range 0.05 – 17.52). This is the first study evaluating the bone health of female GAA players. The preliminary results from the suggested indicators for monitoring are unremarkable to date. We await the analysis of the bone turnover markers and further interval evaluation, to assess the impact of the playing season. We hope that our study will lead to improved education and ultimately better health, performance and safe participation for women in sport.
