Relative Energy Deficiency in Sport (RED-S) syndrome is associated with undesirable health and performance outcomes. The aetiology of RED-S syndrome is low energy availability (LEA). LEA has been reported in male athletes in various sports, but there is little information in team sports. Therefore, the aims of this study were to assess the point-prevalence of surrogate markers of LEA in elite male volleyball players and examine the association between low and normal total-testosterone (TES) on endocrine markers, resting metabolic rate, bone mineral density (BMD), and history of injury/illness. Using a cross-sectional design, 22 elite male volleyball players underwent anthropometric, dual-energy X-ray absorptiometry (DEXA or DXA) and resting metabolic rate testing, bloodwork, dietary analysis, the three-factor eating questionnaire-R18, injury/illness questionnaire and Victorian Institute of Sport Assessment - patellar tendon questionnaire. The primary finding of this investigation was that 36% of athletes had ≥2 surrogate markers of LEA. Although fasted insulin was lower and cortisol was higher in players with low-total TES, low BMD, low RMR and various other endocrine markers linked to LEA were not observed. More research is required to define surrogate markers of LEA in male athletes. Thirty-six percent of volleyball players had ≥2 surrogate markers of LEA.The Cunningham, 1991 predictive RMR equation and/or the cut-off point (<0.9) may be unsuitable for detecting energy conservation associated with LEA in large male athletes.There was no association between total-TES and risk of bone stress injury, illness and patellar tendinopathy.
运动相关的能量不足（RED-S）综合征与不良的健康和运动表现结果有关。RED-S 综合征的病因是能量不足（LEA）。在各种运动项目的男性运动员中已经报道了 LEA，但在团队运动项目中，相关信息很少。因此，本研究的目的是评估精英男性排球运动员中 LEA 的替代标志物的现患率，并检查低和正常总睾酮（TES）与内分泌标志物、静息代谢率、骨密度（BMD）和损伤/疾病史之间的关联。使用横断面设计，22 名精英男性排球运动员接受了人体测量学、双能 X 射线吸收法（DEXA 或 DXA）和静息代谢率测试、血液检查、饮食分析、三因素饮食问卷-R18、损伤/疾病问卷和维多利亚州运动评估 - 髌腱问卷。本研究的主要发现是，36%的运动员有≥2 个 LEA 的替代标志物。尽管低总 TES、低 BMD、低 RMR 和与 LEA 相关的其他各种内分泌标志物的运动员的空腹胰岛素较低，皮质醇较高，但没有观察到这种情况。需要进一步研究来定义男性运动员的 LEA 替代标志物。36%的排球运动员有≥2 个 LEA 的替代标志物。Cunningham，1991 年预测的 RMR 方程和/或截止点（<0.9）可能不适合检测与 LEA 相关的大型男性运动员的能量节约。总 TES 与骨应激损伤、疾病和髌腱病的风险之间没有关联。
