The present study examined the prevalence of dietary supplement use among elite figure skaters, gender differences in supplement use, and differences in nutrient intake of supplement users versus non-users. Male (n = 46) and female (n = 59) figure skaters completed a supplement survey and 3-day food records. Descriptive analysis, chi-square test, and independent t tests were used to analyze the data. Sixty-five percent of male (n = 30) and 76% of female (n = 45) figure skaters reported use of supplements. Forty-seven percent of males and 55% of females reported daily use of supplements. Multivitamin-mineral supplements were the most popular dietary supplements consumed by figure skaters. Significant gender differences were observed in the use of multivitamin-mineral supplements (61% males vs. 83% females, p < .05). Echinacea and ginseng were popular herbal supplements used by these skaters. The 3 main reasons given by male figure skaters for taking supplements were: to provide more energy (41%), to prevent illness or disease (34%), and to enhance performance (21%). Among female figure skaters, the 3 main reasons given were: to prevent illness or disease (61%), to provide more energy (39%), and to make up for an inadequate diet (28%). Significant differences (p < .05) were observed in protein, total fat, saturated fat, polyunsaturated fat intakes, and % energy from carbohydrate and total fat of male supplement users versus non-users, with supplement users having higher intakes except for percent energy from carbohydrate. Sodium was the only nutrient significantly different (p < .05) among female supplement users versus non-users, with supplement users having lower intakes. Given the popularity of dietary supplements, it is important to understand the factors influencing athletes' use of supplements, their knowledge and attitudes regarding supplements, dosage of supplements used, and the effectiveness of these dietary supplements in meeting the goals of the athletes.
本研究调查了优秀花样滑冰运动员使用膳食补充剂的情况、补充剂使用中的性别差异,以及补充剂使用者与非使用者在营养摄入方面的差异。男(n = 46)、女(n = 59)花样滑冰运动员完成了一份补充剂调查问卷和3天的饮食记录。采用描述性分析、卡方检验和独立样本t检验对数据进行分析。65%的男性(n = 30)和76%的女性(n = 45)花样滑冰运动员报告使用了补充剂。47%的男性和55%的女性报告每天使用补充剂。多种维生素 - 矿物质补充剂是花样滑冰运动员最常食用的膳食补充剂。在多种维生素 - 矿物质补充剂的使用上观察到显著的性别差异(男性为61%,女性为83%,p < .05)。紫锥菊和人参是这些滑冰运动员常用的草本补充剂。男性花样滑冰运动员服用补充剂的3个主要原因是:提供更多能量(41%)、预防疾病(34%)、提高成绩(21%)。在女性花样滑冰运动员中,给出的3个主要原因是:预防疾病(61%)、提供更多能量(39%)、弥补饮食不足(28%)。男性补充剂使用者与非使用者在蛋白质、总脂肪、饱和脂肪、多不饱和脂肪摄入量以及碳水化合物和总脂肪的能量百分比方面存在显著差异(p < .05),补充剂使用者的摄入量较高,但碳水化合物的能量百分比除外。钠是女性补充剂使用者与非使用者之间唯一有显著差异(p < .05)的营养素,补充剂使用者的摄入量较低。鉴于膳食补充剂的普遍使用,了解影响运动员使用补充剂的因素、他们对补充剂的知识和态度、所使用补充剂的剂量,以及这些膳食补充剂在实现运动员目标方面的有效性非常重要。
