摘要

背景:超极限高强度间歇训练(HIT)计划在外部研究环境中具有挑战性。本研究旨在结合运动参与者和教练的观点,探讨其在社区环境下对老年人的可行性。方法:采用融合混合方法设计的实用可行性研究,包括来自一家训练机构的4名运动教练和21名老年运动参与者(14名女性,年龄范围65-78岁)。以前使用的HIT计划包括20分钟的训练,包括热身、10次6秒的间歇和冷却。教师首先围绕这些核心内容调整课程以适应他们的环境,然后进行了25次会议。同时收集定性(个人访谈)和定量(估计最大耗氧量、估计6秒功率、运动相关动机和自我效能)数据并进行分析(内容分析和描述性统计)。实施结果的分类被用作分析矩阵。结果:参与者和教练的经验表明,培训结构被认为是引人入胜的,令人愉快的,并且支持建立常规和促进培训进展的所有权。参与者发现了个性化和激励的方法来参与项目,并增强了对自己能力的信心。运动相关动机和自我效能感的变化呈现个体差异,无群体趋势。完成干预的参与者在估计的6秒功率和最大耗氧量方面显示出正的中位数变化,尽管个体反应有所不同。经历过的挑战包括在间隔期间协调任务和管理方案的信心。保真度和放大的障碍与实际的复杂性和固定的结构有关。结论:通过适当的支持,包括个体化的基于瓦特的强度和结构化的进展,可以在社区环境中对老年人实施超最大化HIT。研究结果强调了参与者如何掌握自己的强度进步,使他们能够挑战自己的极限。然而,管理短间隔的固定结构和复杂性可能会对更广泛的采用构成障碍。为了增强可行性和可扩展性,建议简化区间管理并提供清晰、结构化的指导。这些见解有助于改进和优化社区环境中老年人的最高HIT实施。试验注册:2023年1月31日开放科学框架(https://doi.org/10.17605/OSF.IO/B7T2G)。

Background: Supramaximal high-intensity interval training (HIT) programmes can be challenging to replicate outside research settings. This study aimed to explore its feasibility for older adults in a community setting, incorporating perspectives from exercise participants and instructors.

Methods: A pragmatic feasibility study using a convergent mixed- methods design involving four exercise instructors from one training facility and 21 older adult exercise participants (14 women, age-range 65-78). The previously used HIT programme consisted of 20-minute sessions that included a warm-up, ten 6-second intervals, and cool-down. Instructors first adapted the programme around these core components to their setting and then conducted 25 sessions. Both qualitative (individual interviews) and quantitative (estimated maximal oxygen consumption, estimated 6-second power, exercise- related motivation, and self-efficacy) data were collected and analysed (content analysis and descriptive statistics) in parallel. A taxonomy for implementation outcomes was used as an analytical matrix.

Results: Experiences of both participants and instructors revealed that the structure of the training was regarded as engaging, enjoyable, and supportive for establishing routines and promoting ownership of training progression. Participants found personalised and motivating approaches to engage with the programme and confidence in their abilities grew. Changes in exercise-related motivation and self-efficacy showed individual variation without a group trend. Participants who completed the intervention showed a positive median change in estimated 6-second power and maximal oxygen consumption, although individual responses varied. Experienced challenges included coordinating tasks during intervals and confidence in managing the programme. Barriers to fidelity and to scale-up were related to the practical complexity and fixed structure.

Conclusions: Supramaximal HIT can be implemented for older adults in a community setting with appropriate support, including individualised watt-based intensity and structured progression. The findings highlight how participants took ownership of their intensity progression, enabling them to challenge their limits. However, the fixed structure and complexity in managing short intervals may pose barriers to broader adoption. To enhance feasibility and scalability, simplifying interval management and providing clear, structured guidance are recommended. These insights help refine and optimize supramaximal HIT implementation for older adults in community settings.

期刊介绍: European Review of Aging and Physical Activity (EURAPA) disseminates research on the biomedical and behavioural aspects of physical activity and aging. The main issues addressed by EURAPA are the impact of physical activity or exercise on cognitive, physical, and psycho-social functioning of older people, physical activity patterns in advanced age, and the relationship between physical activity and health.
