This study's purpose was to evaluate the relationship between dance training volume, body composition, and habitual diet in female collegiate dancers.
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/m) 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 -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 ( < 0.05).
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).
Our findings emphasize the positive effect of adequate nutritional quantity and quality on body composition in female collegiate dancers.
本研究旨在评估舞蹈训练量、身体成分和女性大学生舞蹈运动员的习惯性饮食之间的关系。
来自三个舞蹈项目的 33 名女性大学生舞蹈运动员(20.4 ± 1.05 岁;165.4 ± 11.3cm,BMI 21.3 ± 3.4kg/m2)参与了“跨校艺术运动员研究评估(TIAARA)”研究。我们评估了舞蹈训练量、身体成分和习惯性饮食。使用描述性统计(均值 ± SD)分析数据。采用两样本 t 检验比较报告的摄入量值与运动营养建议。进行双侧 Pearson 相关分析(r),以评估身体成分和饮食摄入之间的相关性(<0.05)。
大学生舞蹈运动员的平均每学期学分修读数为 16 ± 2.09 个学分,其中 7.7 ± 3.8 个学分是舞蹈运动课程,每周额外有 3.0 ± 1.5 小时的排练时间。身体成分评估包括体脂肪(24.4 ± 6.8%)、去脂体重(LM)(42.4 ± 10.1kg)和总体水(32.6 ± 4.6L)。习惯性饮食反映出低热量饮食(1399 ± 648kcal/d),约 20%的舞蹈运动员摄入极低热量饮食(≤1000kcal/d)。舞蹈运动员报告蛋白质(54.3 ± 26.2g)和碳水化合物(171.8 ± 77.8g)的摄入量不足。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。
本研究结果强调了充足的营养数量和质量对女性大学生舞蹈运动员身体成分的积极影响。
