Previous studies show that in-person dance training is a beneficial form of physical activity that involves mental, social, and physical dimensions. This exploratory study investigated the benefits of a 12-week online dance training intervention on mental and physical health outcomes for older women.
A convergent parallel mixed-method design was used. Forty-five older adults (74.0 ± 5.3 yrs old, 44 women) were recruited through advertisements at activity and rehabilitation centers in the North Denmark region. The intervention consisted of two weekly 60-min classes of improvisation and salsa delivered online through video call applications. Changes in physical health outcomes (body mass and composition, resting blood pressure, Senior Fitness Test battery) and self-rated health and wellbeing (health-related quality of life (HRQOL), feelings of loneliness) were assessed prior to and after 12 weeks of dancing. Focus group interviews were conducted post-intervention to further explore the benefits as well as the participant's experience of the intervention. Thematic analysis of the qualitative data was conducted.
Thirty-two participants (all women) completed the study. Significant improvements in fitness were found for the number of arm curls performed (baseline: 12.3 ± 3.0; post-intervention: 13.7 ± 3.0, P = 0.005), 2-min step test performance (baseline: 66.5 ± 20.0 reps.; post-intervention: 73.8 ± 22.6 reps., P = 0.016), and chair sit-and-reach (baseline: 0.4 ± 11.3 cm; post-intervention: 5.5 ± 10.1 cm, P < 0.001). There was a significant increase in body mass from baseline to post-intervention (P < 0.015). The themes from the focus groups included (1) Participation, (2) Challenges, (3) Progression, (4) Motivation, (5) Perceived health and wellbeing, and (6) Online dance instruction. No significant changes were reported in HRQOL and loneliness from the quantitative data, although the qualitative data did reveal improved feelings of physical health and wellbeing.
The intervention improved several aspects of fitness in older women and improved the participants' perceptions of their own physical abilities and wellbeing. While most participants found the online intervention enjoyable, several participants missed the feedback from the instructors that naturally occurs with in-person instruction.
先前的研究表明，亲身参与的舞蹈训练是一种有益的身体活动形式，涉及心理、社会和身体等多个方面。本探索性研究调查了为期 12 周的在线舞蹈训练干预对老年女性的心理健康和身体健康结果的影响。
采用汇聚平行混合方法设计。通过在丹麦北部地区的活动和康复中心发布广告，招募了 45 名老年女性（74.0±5.3 岁）。该干预措施包括每周两次的 60 分钟即兴和莎莎舞在线课程，通过视频通话应用程序进行。在 12 周的舞蹈训练前后，评估了身体健康结果（体重和成分、静息血压、老年人健康测试电池）和自我评估的健康和幸福感（健康相关生活质量（HRQOL）、孤独感）。干预后进行焦点小组访谈，进一步探讨干预的益处以及参与者的体验。对定性数据进行主题分析。
32 名参与者（均为女性）完成了研究。在完成的 32 名参与者中，发现手臂弯曲次数（基线：12.3±3.0；干预后：13.7±3.0，P=0.005）、2 分钟踏步测试表现（基线：66.5±20.0 次；干预后：73.8±22.6 次，P=0.016）和坐站测试（基线：0.4±11.3 厘米；干预后：5.5±10.1 厘米，P<0.001）等方面的健身表现有显著提高。与基线相比，身体质量有显著增加（P<0.015）。焦点小组的主题包括（1）参与，（2）挑战，（3）进展，（4）动机，（5）感知健康和幸福感，以及（6）在线舞蹈教学。从定量数据来看，HRQOL 和孤独感没有显著变化，尽管定性数据确实显示出身体更健康和幸福感的改善。
该干预措施改善了老年女性的多个方面的健康，提高了参与者对自己身体能力和幸福感的认知。虽然大多数参与者认为在线干预很有趣，但一些参与者错过了与亲自指导时自然产生的来自教练的反馈。
