Aging is accompanied by a decline in multiple domains. Positive effects of dance practice on several health issues have been evaluated in young adults, while the effects of regular social dance practice on physical fitness, sexual health, and cognitive functions have not been studied yet in older experienced dancers. Thus, the aim of this study has been to investigate whether a 6-month social dance practice might influence fitness performance, sexual health, and specific cognitive functions and/or mood characteristics in older experienced dancers. Thirty experienced dancers (age: 71.2±5.1 years, 18 females/12 males) were enrolled from the dance school "NonSoloLiscio" of Catanzaro. Body composition, physical fitness, sexual health, and cognitive functions were assessed before (T0) and after (T6) intervention. After 6 months of dance practice, percent of fat mass (%FM) significantly decreased (p<0.01), while fat-free mass (FFM) significantly increased (p<0.01) in both genders. Moreover, significant main effects of time on physical fitness tests, such as chair stand test (CST) (p<0.01), gait speed (p<0.05), and timed up and go (p<0.05), were found. Sexual health was significantly higher in males than in females at T0 and no significant effects of dance on subjects' sexual health were found. Interestingly, trait of anxiety significant decreased (p<0.05) and perception of retrospective memory significantly increased (p=0.05) after training independently of gender. Our preliminary results suggest that, even in older intermediate-level dancer, the practice of social dance might positively influence body composition and also increase fitness performance, memory functions, and anxiety. In contrast, no effects on sexual health were observed after 6 months of dancing.
衰老伴随着多个领域的衰退。舞蹈练习对年轻人的多种健康问题的积极影响已得到评估，而定期社交舞蹈练习对老年有经验舞者的身体素质、性健康和认知功能的影响尚未得到研究。因此，本研究的目的是调查6个月的社交舞蹈练习是否可能影响老年有经验舞者的体能表现、性健康、特定认知功能和/或情绪特征。从卡坦扎罗的“NonSoloLiscio”舞蹈学校招募了30名有经验的舞者（年龄：71.2±5.1岁，18名女性/12名男性）。在干预前（T0）和干预后（T6）评估身体成分、身体素质、性健康和认知功能。经过6个月的舞蹈练习，男女两性的脂肪量百分比（%FM）显著下降（p<0.01），而无脂肪量（FFM）显著增加（p<0.01）。此外，还发现时间对身体素质测试有显著的主效应，如椅子站立测试（CST）（p<0.01）、步速（p<0.05）和定时起立行走测试（p<0.05）。在T0时，男性的性健康显著高于女性，且未发现舞蹈对受试者性健康有显著影响。有趣的是，训练后焦虑特质显著下降（p<0.05）且回顾性记忆感知显著增加（p=0.05），与性别无关。我们的初步结果表明，即使是老年中级水平的舞者，社交舞蹈练习也可能对身体成分产生积极影响，还能提高体能表现、记忆功能和减轻焦虑。相比之下，跳舞6个月后未观察到对性健康有影响。
