Introduction To minimise adverse health events among older adults, physical activity (PA) is considered one of the most fundamental and effective forms of lifestyle. Therefore, an urgent effort to promote a physically active lifestyle among our older adults is needed, in which walking could be a better choice, especially for mass promotion. Besides, the types of PA interventions were also shown to affect their effectiveness on older adults’ psychosocial outcomes. Hence, the overall aim of the project is to examine the effectiveness of supervised group-based walking intervention by comparing it with unsupervised group-based walking and unsupervised individual-based walking interventions on improving physical, psychological and social outcomes among older adults in Hong Kong.Methods and analysis The research will conduct a four-group (supervised group-based, unsupervised group-based walking, unsupervised individual-based, control group), double-blind, randomised control trial, targeting 184 older adults in Hong Kong. The primary outcomes will be measured by participants’ changes in resting heart rates, body compositions, resting blood pressures, walking performance, loneliness, perceived social support and PA enjoyment. The results will be analysed using repeated analysis of variance and one-way analysis of covariance, as well as by conducting in-depth interviews with selected participants. Also, the outcomes of the research will be used as references for designing an effective walking operation manual for promoting healthy ageing among older adults in the community.Ethics and dissemination The current study involves human participants, and the research protocol has been approved by the research ethics committee at Hong Kong Baptist University (Ref: R2022-2023-0013). All participants will be provided with written informed consent to participate. The outcomes of the intervention protocol will be disseminated through manuscript publications.Trial registration number The trial is registered at the ClinicalTrials.gov PRS (Trial ID: NCT05907252; date of first posted: 16 June 2023).

Walking is widely recognized as one of the most common and effective forms of physical activity, particularly for older adults. This study examined the comparative effects of two types of walking interventions, including supervised group-based intervention (SGBI) and non-supervised individual-based intervention (NSIBI), on frailty syndrome, cognitive functions or skills, and health-related quality of life among sedentary older Saudi individuals. A 15-week double-blinded, randomized controlled trial (RCT) including three groups (two were intervention groups while the other was the control group) was conducted among older adults who were inactive to examine the effect of different forms of walking interventions on frailty syndrome, cognitive functions, and health-related quality of life. A total of 107 participants, including 65 males and 42 females, were divided into three groups, which include SGBI, NSIBI, and the control group. Frailty syndrome was measured using the physical performance test (PPT), while cognitive function and health-related quality of life were assessed using the Mini-mental State Examination (MMSE) and the Short Form 36 (SF 36) health survey questionnaire. One-way repeated measures analysis of variance (ANOVA) and one-way analysis of covariance (ANCOVA) with the pre- and post-tests were performed for within- and between-group differences. while post-test data for the control group participants were absent due to the change in elderly center regulation, and they were excluded from the analysis. Hence, the comparison was stated only between the intervention groups. Both of the intervention groups (SGBI and NSIBI) showed significant within-subject differences in the Physical Function subscale of the health-related quality of life scale only, with F(1,20) = 23.03, p < 0.001, and F(1,18) = 27.22, p < 0.001, respectively. On the other hand, the Physical Performance Test revealed significant [F(2,51) = 9.21, p < 0.001] between-group differences in the post-test based on the baseline values. In addition, the average step count of older adults was increased from 4000 steps per session to around 7000 steps per session in the intervention group. The average heart rate of the NSIBI group did not show a visible change, and the resting heart rate of both groups showed a slightly declining trend throughout the intervention period. The walking intervention significantly increased participants’ physical function, which is a component of health-related quality of life and physical performance (frailty level), along with average daily step counts for older adults in Saudi Arabia. Regular engagement in the recommended level of walking is strongly advisable for Saudi Arabian older adults to maintain their overall quality of life at this stage.

Esports is a rapidly growing industry worldwide, and it is making significant inroads in Hong Kong as well. However, owing to debates regarding the distinction between Esports and video gaming and the potential negative effects of engaging in Esports, its development in Hong Kong is still in its infancy. Therefore, this qualitative study investigated the perceptions and attitudes of teenagers and young adults toward Esports development and engagement, using the theory of planned behavior. Twenty-five teenagers and young adults (male = 24, female =1) participated in this study, with their ages ranging from 15 to 29 years. Our results revealed the views of Hong Kong teenagers and young adults on the beneficial and deleterious outcomes (goal setting and achievement, physical health, socialization and teamwork, psychological benefits, academics and time distribution, physical strain, negative social image, and perception toward sport participation), subjective norms (parents, peers, teachers, and modeling effect), and barriers and facilitators (balance between academics and Esports, capability, career prospects and future reality, psychological benefits, and peer encouragement and support) of participating in Esports. Additionally, the results of this qualitative study may contribute toward a deeper understanding of Hong Kong Esports players to develop a theory of planned behavior construct for capturing the beliefs and perceptions of Hong Kong teenagers toward Esports.
