: Preserving health and physical fitness is critical to ensure independent living across the lifespan. Lower levels of physical fitness are associated with age-related cognitive decline and a higher prevalence of mild cognitive impairment (MCI). Thus, this study investigates the influence of a six-month dance intervention on selected measures of physical fitness in older adults with MCI. : In this randomized controlled trial, 55 patients with MCI were randomized into a sportive dance training (IG; = 26; age: 70.7 ± 5.6 years; 62% female) or an inactive control group (CG; = 24; age: 69.1 ± 6.8 years; 46% female). The dance group received two 90 min dance training sessions per week over a duration of six-months, which focused on learning dance movement patterns. During the training sessions, heart rate was measured to control exercise intensity. Physical fitness was assessed using cardiopulmonary exercise testing (CPET), lower limb functional fitness via sit-to-stand test, handgrip strength, and heart rate variability (HRV). : We observed that the dance intervention preserved the cardiorespiratory fitness as measured by maximal oxygen uptake (VO) during CPET, which decreased in the CG. Furthermore, participants in the IG demonstrated increases in leg and handgrip strength, although these were not statistically significant. HRV displayed a non-significant decrease following the intervention. : The results of this randomized controlled trial suggest that sportive dance training can preserve elements of physical fitness (i.e., cardiorespiratory fitness) in older adults with MCI. Although improvements in the other parameters (i.e., leg and handgrip strength) were statistically non-significant, likely due to the small sample size, stabilizing muscular fitness and preventing age-related decline in older adults with MCI is important for maintaining functional independence. For future studies, we recommend a longer training duration paired with precise control of regular physical activity levels, an important confounding factor.
保持健康和体能对于确保一生的独立生活至关重要。较低的体能水平与年龄相关的认知衰退以及轻度认知障碍（MCI）的较高患病率相关。因此，本研究调查了为期六个月的舞蹈干预对患有MCI的老年人选定体能指标的影响。
在这项随机对照试验中，55名MCI患者被随机分为体育舞蹈训练组（干预组；n = 26；年龄：70.7±5.6岁；62%为女性）或非活动对照组（对照组；n = 24；年龄：69.1±6.8岁；46%为女性）。舞蹈组在六个月的时间里每周接受两次90分钟的舞蹈训练课程，重点是学习舞蹈动作模式。在训练课程期间，测量心率以控制运动强度。使用心肺运动测试（CPET）评估体能，通过坐立试验评估下肢功能体能、握力和心率变异性（HRV）。
我们观察到，舞蹈干预在CPET期间通过最大摄氧量（VO）测量保持了心肺适能，而对照组的心肺适能则有所下降。此外，干预组的参与者腿部和握力有所增加，尽管这些增加在统计学上并不显著。干预后HRV显示出不显著的下降。
这项随机对照试验的结果表明，体育舞蹈训练可以在患有MCI的老年人中保持体能要素（即心肺适能）。尽管其他参数（即腿部和握力）的改善在统计学上不显著，可能是由于样本量较小，但稳定患有MCI的老年人的肌肉适能并防止与年龄相关的衰退对于维持功能独立性很重要。对于未来的研究，我们建议延长训练时间并精确控制规律身体活动水平，这是一个重要的混杂因素。
