Important Note: Redirection of Services to ChiCTR
We would like to inform you that the Clinical Trial Registry page will discontinue the function of updating trial information directly on this platform. However, you will still be able to view the existing registration details. For any updates to trial information, you can use the China Clinical Trial Registry (ChiCTR) directly at https://www.chictr.org.cn. This change will be fully implemented by 2024-Aug-05. Thank you for your attention.

Moderate-intensity exercise-based intervention
The moderate-intensity endurance exercise training will be conducted by a research assistant with baccalaureate training in physical education or sport medicine (RA1). The Co-Is (S. Ng and P.Siu) who are academicians in physiotherapy and exercise physiologist will conduct a 3-day training to the RA1. The exercise training is designed with the assistance of the Co-Is according to the recommendations of the American College of Sports Medicine (ACSM)’s position stand on Exercise and Physical Activity for Older Adults. Our proposed exercise intervention is a moderate-intensity 7.5cm-high bench stepping exercise program for Seniors. It is a 16-week program, with three 60-minute group training sessions (group size: around 10) per week. Each session starts with a 10-minute warm-up period using stretching exercise and stationary mobilizing exercise for trunk and limb joints at both upper and lower bodies (e.g. shoulders, elbows, wrists, hips, knees and ankles), and followed by a session of moderate-intensity endurance exercise. The duration of the endurance exercise will increase gradually from 20 minutes to the targeted 40 minutes in four weeks’ time. The endurance exercise includes bench stepping exercise using a 7.5cm-high stable wooden platform. This exercise has been shown to be very suitable for older people who are less physically active or have reduced joint flexibility and reduced bone strength. Subjects will perform the bench stepping exercise in bouts of at least 10 minutes each (with maximum 5 minutes of rest in between the exercise bouts) to reach the targeted duration (i.e. 40 minutes of endurance exercise). Close monitoring and verbal encouragement will be provided by the attending RA. Moderate-intensity exercise has been widely used among older people and is even safe for older patients with chronic diseases. The Borg Rate of Perceived Exertion will be used to monitor the exercise intensity. This 15-point scale with scores ranging from 6-20. Descriptors are attached throughout the scale with higher scores indicating more perceived exertion. Physical activity that results in a rating of 12-14 (descriptor: “somewhat hard”) on the Borg RPE is identified as reaching a moderate intensity.24 The RA1 will explain the Borg RPE scale to the subjects and instruct them to speed up or slow down their movements in order to achieve a feeling of ‘somewhat hard’ at the Borg RPE rating of 12-14. The training session will end with a 10-minute cool down session with walking exercise and stationary trunk and limb mobilizing exercise involving joints of shoulders, elbows, wrists, hips, knees, and ankles. The training will follow the ACSM safety guidelines with assessment done on BP, HR and contradictory symptoms prior to training. Attendance rate and adverse events will be recorded. The PI (Professional Nurse) and Co-I (J Woo; Geriatrician) will manage any adverse events.

3 sessions/ week for 16 weeks
The 16-week health education programme will be delivered as a non-active attention placebo by a part-time research nurse (RA2). It includes sixteen 60-minute education sessions delivered on a weekly basis. Various health topics on home safety, brain health, foot care, flu prevention, medication management, aging and nutrition, common chronic illness among older adults, voucher scheme for elderly, smart grandparenthood, tips in choosing health screening, etc. will be included. No information relating to sleep and physical activity will be included.
