Abstract

Background: This study's purpose was to evaluate the relationship between dance training volume, body composition, and habitual diet in female collegiate dancers.

Methods: Thirty-three female collegiate dancers from three dance programs (20.4 ± 1.05 yrs.; 165.4 ± 11.3 cm, BMI 21.3 ± 3.4 kg/m²) participated in "The Intercollegiate Artistic Athlete Research Assessment (TIAARA)" study. We assessed dance training volume, body composition, and habitual diet. Data were analyzed using descriptive statistics (means ± SD). Two-sample t-tests were conducted to compare reported intake values versus sports nutrition recommendations. Two-tailed Pearson correlations (r) were computed for body composition and dietary intake (p < 0.05).

Results: Collegiate dancers were enrolled in 16 ± 2.09 semester credits, with 7.7 ± 3.8 credits as dance movement courses and an additional 3.0 ± 1.5 h/week of rehearsal time. Body composition assessments included fat mass (24.4 ± 6.8%), lean mass (LM) (42.4 ± 10.1 kg), and total body water (32.6 ± 4.6 L). Habitual diets reflected a low-calorie diet (1399 ± 648 kcal/d), with ~20% of dancers consuming a very low-calorie diet (≤1000 kcal/d). Dancers reported under-consuming dietary protein (54.3 ± 26.2 g) and carbohydrate (171.8 ± 77.8 g). LM was positively correlated with daily total energy (r = 0.333), fat (r = 0.37), protein (r = 0.349), and leucine intake (r = 0.352).

Conclusions: Our findings emphasize the positive effect of adequate nutritional quantity and quality on body composition in female collegiate dancers.

女大学生舞蹈演员的舞蹈训练量、身体成分和习惯饮食之间的关系：校际艺术运动员研究评估（TIAARA）研究。

研究背景本研究旨在评估女大学生舞蹈演员的舞蹈训练量、身体成分和习惯饮食之间的关系：来自三个舞蹈专业的 33 名大学女生（20.4 ± 1.05 岁；165.4 ± 11.3 厘米，体重指数 21.3 ± 3.4 公斤/平方米）参加了 "大学间艺术运动员研究评估（TIAARA）"研究。我们对舞蹈训练量、身体成分和习惯性饮食进行了评估。数据分析采用描述性统计（均值±标准差）。采用双样本 t 检验比较报告摄入值与运动营养推荐值。对身体成分和饮食摄入量计算双尾皮尔逊相关性（r）（p < 0.05）：大学生舞蹈演员共修 16 ± 2.09 个学期学分，其中 7.7 ± 3.8 个学分为舞蹈动作课程，另外每周排练时间为 3.0 ± 1.5 小时。身体成分评估包括脂肪量（24.4 ± 6.8%）、瘦肉量（42.4 ± 10.1 kg）和身体总水分（32.6 ± 4.6 L）。习惯饮食反映出低热量饮食（1399 ± 648 千卡/天），约 20% 的舞者摄入超低热量饮食（≤1000 千卡/天）。据报告，舞蹈演员的膳食蛋白质（54.3 ± 26.2 克）和碳水化合物（171.8 ± 77.8 克）摄入不足。LM 与每日总能量（r = 0.333）、脂肪（r = 0.37）、蛋白质（r = 0.349）和亮氨酸摄入量（r = 0.352）呈正相关：我们的研究结果强调了充足的营养数量和质量对女大学生舞蹈演员身体成分的积极影响。
