This study investigated the efficacy of participation in culture-specific dancing to meet current physical activity recommendations and increase cardio-respiratory fitness in postmenopausal women. Sedentary postmenopausal women (n = 24), aged 63 ± 8 years and with BMI of 28 ± 3 kg/m completed a 4-week Scottish dancing study. The dancing sessions of approximately 75 min were performed twice a week and each session was based on five Scottish dances performed in 3 sets. Heart rate (HR) measurements were obtained during all dances to evaluate whether the intervention achieves the criteria of moderate to vigorous aerobic exercise intensity. Body composition, waist circumference, and HR during Chester Step test were measured before and after dancing intervention. HR achieved during individual dances ranged from 64 ± 5% to 80 ± 5% of HRmax and the mean HR of the five dances corresponded to 72 ± 7% of HRmax. Post-intervention mean HR was lower throughout Level 2 (Pre, 112 ± 13 bpm; Post, 106 ± 13 bpm; = 0.005) and Level 3 (Pre, 122 ± 14 bpm; Post, 115 ± 14 bpm; = 0.006) of the Chester test compared with baseline values. The intervention had no impact on body weight or body fat but reduced waist circumference (Pre, 94 ± 8 cm; Post, 91 ± 9 cm; = 0.006). Thus, traditional Scottish dancing should be advocated to sedentary postmenopausal women, emphasising its potential in meeting current physical activity recommendations in relation of weekly duration and exercise intensity and improving cardiorespiratory fitness.
本研究旨在探讨参与特定文化的舞蹈活动是否能达到当前的身体活动建议标准,并提高绝经后妇女的心肺健康水平。24 名久坐的绝经后妇女(年龄 63 ± 8 岁,BMI 为 28 ± 3 kg/m)参加了为期 4 周的苏格兰舞蹈研究。舞蹈课程大约 75 分钟,每周进行两次,每次课程包括 5 种苏格兰舞蹈,分为 3 组进行。在进行所有舞蹈时测量心率(HR),以评估干预措施是否达到中等至剧烈有氧运动强度的标准。在跳舞干预前后测量身体成分、腰围和 Chester 步测试时的 HR。个别舞蹈的 HR 范围为 HRmax 的 64 ± 5%至 80 ± 5%,5 种舞蹈的平均 HR 对应 HRmax 的 72 ± 7%。干预后,Chester 测试的第 2 级(干预前 112 ± 13 bpm,干预后 106 ± 13 bpm; = 0.005)和第 3 级(干预前 122 ± 14 bpm,干预后 115 ± 14 bpm; = 0.006)的平均 HR 均低于基线值。该干预措施对体重或体脂没有影响,但减少了腰围(干预前 94 ± 8 cm,干预后 91 ± 9 cm; = 0.006)。因此,应提倡传统的苏格兰舞蹈给久坐的绝经后妇女,强调其在满足当前身体活动建议方面的潜力,包括每周持续时间和运动强度,并提高心肺健康水平。
