Bodybuilding is a sport where coaches commonly recommend a variety of nutrition and exercise protocols, supplements, and, sometimes, performance-enhancing drugs (PEDs). The present study sought to gain an understanding of the common decisions and rationales employed by bodybuilding coaches. Focusing on coaches of the more muscular divisions in the National Physique Committee/IFBB Professional League federations (men's classic physique, men's bodybuilding, women's physique, women's bodybuilding) for both natural and enhanced athletes, coaches were recruited via word of mouth and social media, and 33 responded to an anonymous online survey. Survey responses indicated that participant coaches recommend three-to-seven meals per day and no less than 2 g/kg/day of protein regardless of sex, division, or PED usage. During contest preparation, participant coaches alter a natural competitor's protein intake by -25% to +10% and an enhanced competitor's protein intake by 0% to +25%. Regarding cardiovascular exercise protocols, approximately two-thirds of participant coaches recommend fasted cardiovascular exercise, with the common rationale of combining the exercise with thermogenic supplements while considering the athlete's preference. Low- and moderate-intensity steady state were the most commonly recommended types of cardiovascular exercise among participant coaches; high-intensity interval training was the least popular. Creatine was ranked in the top two supplements for all surveyed categories. Regarding PEDs, testosterone, growth hormone, and methenolone were consistently ranked in the top five recommended PEDs by participant coaches. The results of this study provide insight into common themes in the decisions made by bodybuilding coaches, and highlight areas in which more research is needed to empirically support those decisions.
健美运动是一项教练通常会推荐各种营养和锻炼方案、补充剂,有时还会推荐提高成绩药物(PEDs)的运动。本研究旨在了解健美教练所采用的常见决策和基本原理。研究聚焦于国家健体委员会/国际健美健身联合会(IFBB)职业联盟中肌肉量更大级别的教练(男子古典健体、男子健美、女子健体、女子健美),针对自然状态和使用提高成绩药物的运动员,通过口碑和社交媒体招募教练,33名教练回复了一项匿名在线调查。调查回复表明,参与调查的教练建议无论性别、级别或是否使用提高成绩药物,每天进食三到七餐,蛋白质摄入量不少于2克/千克/天。在备赛期间,参与调查的教练会将自然状态参赛选手的蛋白质摄入量减少25%至增加10%,将使用提高成绩药物的参赛选手的蛋白质摄入量增加0%至25%。关于心血管锻炼方案,约三分之二的参与调查教练推荐空腹进行心血管锻炼,常见理由是将这种锻炼与产热补充剂相结合,同时考虑运动员的偏好。低强度和中等强度稳态是参与调查教练最常推荐的心血管锻炼类型;高强度间歇训练最不受欢迎。肌酸在所有调查类别中都位列最常推荐的两种补充剂之中。关于提高成绩药物,睾酮、生长激素和美替诺龙一直被参与调查的教练列为最常推荐的五种提高成绩药物。本研究结果揭示了健美教练决策中的常见主题,并突出了需要更多研究以实证支持这些决策的领域。
