This position stand aims to provide an evidence-based summary of the energy and nutritional demands of tactical athletes to promote optimal health and performance while keeping in mind the unique challenges faced due to work schedules, job demands, and austere environments. After a critical analysis of the literature, the following nutritional guidelines represent the position of the International Society of Sports Nutrition (ISSN).
Nutritional considerations should include the provision and timing of adequate calories, macronutrients, and fluid to meet daily needs as well as strategic nutritional supplementation to improve physical, cognitive, and occupational performance outcomes; reduce risk of injury, obesity, and cardiometabolic disease; reduce the potential for a fatal mistake; and promote occupational readiness.
Energy demands should be met by utilizing the Military Dietary Reference Intakes (MDRIs) established and codified in Army Regulation 40-25. Although research is somewhat limited, military personnel may also benefit from caffeine, creatine monohydrate, essential amino acids, protein, omega-3-fatty acids, beta-alanine, and L-tyrosine supplementation, especially during high-stress conditions.
Specific energy needs are unknown and may vary depending on occupation-specific tasks. It is likely the general caloric intake and macronutrient guidelines for recreational athletes or the Acceptable Macronutrient Distribution Ranges for the general healthy adult population may benefit first responders. Strategies such as implementing wellness policies, setting up supportive food environments, encouraging healthier food systems, and using community resources to offer evidence-based nutrition classes are inexpensive and potentially meaningful ways to improve physical activity and diet habits. The following provides a more detailed overview of the literature and recommendations for these populations.
本立场声明旨在提供有关战术运动员的能量和营养需求的循证总结,以促进最佳健康和表现,同时牢记由于工作时间表、工作要求和艰苦环境而面临的独特挑战。在对文献进行批判性分析后,以下营养指南代表了国际运动营养学会(ISSN)的立场。
营养考虑因素应包括提供和安排足够的卡路里、宏量营养素和液体,以满足日常需求,以及战略性营养补充,以提高身体、认知和职业表现结果;降低受伤、肥胖和心血管代谢疾病的风险;降低致命错误的可能性;并促进职业准备。
应通过利用陆军条例 40-25 中确立和编纂的军事饮食参考摄入量(MDRIs)来满足能量需求。尽管研究有些有限,但军人可能还受益于咖啡因、肌酸一水合物、必需氨基酸、蛋白质、ω-3 脂肪酸、β-丙氨酸和 L-酪氨酸补充剂,特别是在高压力条件下。
特定的能量需求未知,可能因特定职业的任务而异。对于娱乐运动员的一般热量摄入和宏量营养素指南,或者对于一般健康成年人的可接受宏量营养素分布范围,急救人员可能会受益。实施健康政策、建立支持性食品环境、鼓励更健康的食品系统以及利用社区资源提供基于证据的营养课程等策略是提高身体活动和饮食习惯的廉价且有意义的方法。以下提供了针对这些人群的文献和建议的更详细概述。
