Acrobatics & Tumbling (A&T) is an emerging sport in the National Collegiate Athletic Association that lacks research regarding the dietary intake and health of A&T student-athletes (A&Tsa). This study assessed the dietary intake adequacy, estimated energy availability (EA), self-reported menstrual health, and body composition of A&Tsa.
Twenty-four female A&Tsa participated during week 8 of the preseason (11 top: Age= 20.1 ± 0.9 years; BMI= 22.1 ± 1.7 kg/m; 13 base: Age= 19.5 ± 1.3 years; BMI= 26.2 ± 2.7 kg/m). Total energy intake (TEI) and macronutrient intakes were assessed a paper-based 3-day dietary recall. Resting Metabolic Rate [RMR = 500 + 22 * fat-free mass (FFM)] and energy availability [EA = (TEI - exercise energy expenditure)/FFM)] were estimated; and LEAF-Q assessed menstrual health. Body composition was measured using Dual-Energy X-Ray Absorptiometry. Macronutrient intakes and EA were compared to sports nutrition recommendations (carbohydrate: 6-10 g/kg; protein: 1.2-2.0 g/kg) and the Acceptable Macronutrient Distribution Range (carbohydrate: 45-65%; protein: 10-35%; fat: 20-35%).
TEI was 1753 ± 467 kcal (top) and 1980 ± 473.8 kcal (base). A total of 20.8% of A&Tsa failed to meet RMR with TEI, with a higher prevalence in the top (-266 ± 219.2 kcal, = 3) . base (-414.3 ± 534.4 kcal, = 2) A&Tsa. Top and base A&Tsa had both low EA (28.8 ± 13.4 kcals·FFM; 23.8 ± 9.5 kcals·FFM) and inadequate carbohydrate intake averages (4.2 ± 1.3 g/kg; 3.5 ± 1.1 g/kg, < 0.001), respectively. A total of 17% of A&Tsa reported secondary amenorrhea, with a higher prevalence in the top (27.3%, = 3) . the base (7.7%, = 1).
TEI and carbohydrate intake of the majority of A&Tsa were below recommendations. Sports dietitians should encourage and educate A&Tsa about following an adequate diet that meets energy and sports-specific macronutrient needs.
竞技体操是美国全国大学体育协会(NCAA)中的一项新兴运动,但缺乏关于竞技体操学生运动员(A&Tsa)饮食摄入和健康的研究。本研究评估了 A&Tsa 的饮食摄入充足性、估计能量可用性(EA)、自我报告的月经健康状况和身体成分。
24 名女性 A&Tsa 在季前赛的第 8 周参加了研究(11 名顶尖运动员:年龄=20.1±0.9 岁;BMI=22.1±1.7kg/m;13 名基础运动员:年龄=19.5±1.3 岁;BMI=26.2±2.7kg/m)。通过纸质 3 天饮食回忆评估总能量摄入(TEI)和宏量营养素摄入量。静息代谢率[RMR=500+22*去脂体重(FFM)]和能量可用性[EA=(TEI-运动能量消耗)/FFM]进行估算;LEAF-Q 评估月经健康状况。身体成分使用双能 X 射线吸收法进行测量。将宏量营养素摄入量和 EA 与运动营养建议(碳水化合物:6-10g/kg;蛋白质:1.2-2.0g/kg)和可接受的宏量营养素分布范围(碳水化合物:45-65%;蛋白质:10-35%;脂肪:20-35%)进行比较。
TEI 分别为 1753±467kcal(顶尖运动员)和 1980±473.8kcal(基础运动员)。有 20.8%的 A&Tsa 的 TEI 未能满足 RMR,其中顶尖运动员的比例更高(-266±219.2kcal,=3)。基础运动员(-414.3±534.4kcal,=2)。顶尖和基础 A&Tsa 的 EA 均较低(28.8±13.4kcal·FFM;23.8±9.5kcal·FFM),碳水化合物摄入量也均不足(平均 4.2±1.3g/kg;3.5±1.1g/kg,<0.001)。共有 17%的 A&Tsa 报告继发性闭经,其中顶尖运动员的比例更高(27.3%,=3)。基础运动员(7.7%,=1)。
大多数 A&Tsa 的 TEI 和碳水化合物摄入量均低于建议量。运动营养师应鼓励和教育 A&Tsa 遵循充足的饮食,以满足能量和特定运动的宏量营养素需求。
