校际排球是一项强大的运动，包括两到三个小时的比赛;因此，最佳的身体状况是最佳表现的关键。这项研究评估了2009年春季（无干预）和2010年春季（干预淡季）开始和结束时的营养和人体测量参数，以及干预后四个月的额外测量。计算受试者的身体成分、总能量、碳水化合物和蛋白质需求，并评估摄入量。干预措施包括每月一次的个人营养咨询会议的基础上，从三天的食物记录摄入量的分析。食物记录进行了分析，使用营养数据系统的研究软件验证采访。对人体测量和饮食测量进行依赖性T检验。结果显示，在2009年的休赛期，任何参数都没有显着变化，89%的受试者不在推荐的人体测量和饮食指南范围内。在2010年，身体成分显着下降到最佳水平的运动。此外，能量和常量营养素摄入量显著改善，接近推荐指南。四个月后，对受试者的摄入量和身体成分进行了评估，并将结果与2010年春季的结果进行了比较，没有明显变化。这些结果表明，提供营养评估和干预在运动员的体能训练中起着至关重要的作用。
Intercollegiate volleyball is a powerful sport that consists of two to three-hour matches; therefore, optimal physical condition is critical for top performance. This study assessed nutrition and anthropometric parameters at the start and conclusion of both the spring 2009 (no intervention and spring 2010 (intervention off-seasons as well as additional measurements four months after the intervention. The subjects’ body composition, total energy, carbohydrate and protein needs were calculated, and intakes were assessed. The intervention consisted of monthly individual nutrition counseling sessions based on analysis of intake from three-day food records. Food records were analyzed using Nutrient Data Systems for Research software verified by interview. Dependent T-tests were conducted on anthropometric and dietary measurements. The results revealed that during the 2009 offseason, there were no significant change in any parameters and 89% of subjects were not within recommended anthropometric and dietary guidelines. During 2010, body composition significantly decreased to optimal levels for the sport. In addition, energy and macronutrient intake significantly improved toward recommended guidelines. Four months later, the subjects’ intakes and body composition were assessed, and results were compared to the spring 2010 results with no significant changes. These results indicate the providing nutrition assessment and intervention plays a critical role in physical conditioning of athletes.
