Our pilot study has demonstrated improvements in health outcomes through participation in a new sport, light volleyball (LVB), among older adults. In response to the promising results of the LVB pilot study and the priority of allocating resources to the prevention of age-related fitness degradation by the Hong Kong (HKG) government, the present study aims to investigate the effectiveness of a LVB intervention on physical and psychological health attributes among older adults at a larger scale in HKG.
METHODS/DESIGN: This study will apply both quantitative and qualitative methods with a large sample (approximately 315 participants). We will adopt a randomized controlled trial (RCT) design to further evaluate the effectiveness of a LVB intervention on health outcomes against a comparison group, Tai Chi (TC), and a control group (C). Older adults will be eligible to join the intervention if they are (a) aged 65 years and above; (b) living in the community independently; (c) absent of diagnosed cognitive impairment; (d) not regular participants in a structured PA program for two years preceding the study; and (e) able to achieve a passing score on the Timed-up-and-go test (TUG) and Abbreviated Mental Test (AMT).About 315 participants will be randomly assigned into 3 groups in 1:1:1 ratio. LVB group participants will receive 16-week LVB program; TC group will utilize a simplified 24-form Yang Style TC, and C group participants will be instructed to maintain their normal daily activity and join regular non-exercise social gatherings. Measurements will be collected before and after the intervention, and 6 months and 12 months after completion of the intervention.
This intervention, if effective, will enhance older adult's physical and psychological health, and provide the data and evidence to support policymaking in relation to future PA promotion for older adults.

我们的初步研究表明，通过参与一项新的运动——轻排球（LVB），老年人的健康状况得到了改善。鉴于轻排球初步研究取得了令人鼓舞的结果，以及香港特别行政区（HKG）政府将资源分配用于预防与年龄相关的体能下降的优先事项，本研究旨在更大规模地调查轻排球干预对香港特别行政区老年人身心健康属性的有效性。
方法/设计：本研究将采用定量和定性方法，样本量较大（约315名参与者）。我们将采用随机对照试验（RCT）设计，以进一步评估轻排球干预相对于对照组太极拳（TC）和控制组（C）对健康结果的有效性。如果老年人符合以下条件，则有资格参加干预：（a）年龄在65岁及以上；（b）独立生活在社区；（c）未被诊断出认知障碍；（d）在研究前两年内未定期参加结构化体育活动计划；（e）能够在计时起立行走测试（TUG）和简易精神状态检查表（AMT）中获得及格分数。约315名参与者将按1:1:1的比例随机分为3组。轻排球组参与者将接受为期十六周的轻排球计划；太极拳组将采用简化的24式杨式太极拳，控制组参与者将被指导保持正常的日常活动并参加定期的非运动社交聚会。将在干预前后以及干预完成后6个月和12个月收集测量数据。
如果这项干预有效，将增强老年人的身心健康，并为支持未来促进老年人体育活动的政策制定提供数据和证据。
