背景:近年来关于有舞伴型拉丁舞和无舞伴型拉丁有氧舞蹈的研究日益增加,其原因可能是这类舞蹈培训班在主流舞蹈与健身受众中日渐普及,但这些活动的健康促进作用目前尚不清楚。本研究旨在以某一社区中不积极锻炼的女性为样本,对她们接受莎萨舞和尊巴健身舞培训过程中的生理反应和心理体验进行同步评估。方法:对24名受试者(22-56岁)在实验室进行分级运动试验,测试其最大摄氧量和最大心率。然后,受试者在2周内参加了有舞伴型莎萨舞和无舞伴型尊巴健身舞培训课程各2次,课程顺序在参与者间进行了平衡。每次课程长度为1 h,由英国皇室管辖区及伦敦周边社区健身场馆的认证教师授课。通过腕部佩戴加速度计(ActiGraph wGT3X+)和心率监视器收集受试者生理数据,用已有的针对舞蹈的可靠技术加工分析数据,用主观锻炼体验量表测量心理体验。结果:尊巴健身舞用于中高强度体力活动的时间(51.2±3.1 vs.32.6±5.9 min)、总能量消耗(411±66 vs.210±46 kcal)及总步数(556±6773 vs.4108±781步)显著高于莎萨舞(p<0.001)。在两种舞蹈中都观察到积极幸福感(p<0.01,局部η~2=0.41)与心理压力(p<0.001,局部η~2=0.72)在课后较课前有明显改善。结论:对有舞伴型拉丁舞和无舞伴型拉丁有氧舞蹈课程的短期反应表明,对不积极锻炼的女性而言,参与以社区为基础的体力活动和心理健康促进活动确实有效。
BACKGROUND: In recent years, there has been an increasing number of studies on Latin aerobic dance with dance-dancing and dance-free Latin dance because of the increasing popularity of such dance classes among mainstream dance and fitness audiences, but the health promotion of these activities is currently still not clear. The aim of this study is to evaluate women’s physical activity and psychological experience during their training in the Sasa dance and Zumba fitness training by taking samples from women who are not actively exercising in a community. Methods: Twenty-four subjects (22-56 years old) were scored in a lab for grading exercise and their maximal oxygen uptake and maximum heart rate were tested. The subjects then participated in two dance-dance and dance-free Zumba fitness dance classes each two weeks in two weeks, and the order of the courses was balanced among participants. Each course is 1 hour long and is taught by certified instructors in the British Royal Jurisdiction and community gym facilities around London. The subject’s physiological data were collected through a wrist-mounted accelerometer (ActiGraph wGT3X +) and a heart rate monitor, the analytical data was processed using established reliable techniques for dancing, and the psychological experience was measured using a subjective exercise experience meter. Results: The duration of Zumba gymnastic exercise was 51.2 ± 3.1 vs.32.6 ± 5.9 min, the total energy expenditure was 411 ± 66 vs.210 ± 46 kcal and the total number of steps was 556 ± 6773 vs. 4108 ± 781 steps) was significantly higher than the sasa dance (p <0.001). Positive biceps (p <0.01, partial n = 2 = 0.41) and psychological stress (p <0.001, partial n = 2 = 0.72) were observed in both dances significantly after class. CONCLUSIONS: The short-term response to Latin dance with dancers and Latin dance without dance partners suggests that participating in community-based physical and mental health promotion activities is indeed effective for women who do not actively work.
