ABSTRACT
OBJECTIVES: To investigate the effects of physical training on depression and related quality of life in pre-frail and frail individuals. DESIGN: A systematic review and meta-analysis. PARTICIPANTS: Pre-frail and frail older adults. METHODS: Five electronic databases, including PubMed, Cochrane, Medline, CINAHL, and Wiley were searched through December 2023. Randomized controlled trials (RCT) comparing physical training with usual care, health education, or light-intensity exercise were included. Outcomes included depression and depression-related quality of life. The quality of the included studies was assessed using Physiotherapy Evidence Database (PEDro) score, and the Cochrane Risk of Bias Tool was used to assess the risk of bias. Meta-analysis was performed using the RevMan5.4. The certainty of the evidence was evaluated by The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. RESULTS: Ten articles with 589 participants met the inclusion criteria and were included. The pooled analysis indicated that depression (SMD = -0.55, 95%CI = -0.92, -0.17, p = 0.004) and mental health status in life (SMD = 1.05, 95%CI = 0.59, 1.50, p < 0.00001) improved significantly in the experimental group. The results of subgroup analysis revealed that the beneficial effects of physical training were significant only in frail older adults but not in pre-frail older adults. CONCLUSION: This meta-analysis showed that the positive effects of physical training on depression and related quality of life were evident for people with frailty. However, no positive results were observed in pre-frail older adults, indicating the need for further investigation in this subgroup.

OBJECTIVES: To document the effects of square-stepping exercise (SSE) on motor and cognitive function in older adults. METHODS: Five online databases were searched in May 2021. Controlled studies published from 2006 to May 2021 were included. The experimental group received SSE alone or SSE combined with other exercise(s), whereas the control group received no training or other exercise(s). Motor and cognitive outcomes included balance, fall risk, agility, endurance, gait speed, flexibility, muscle strength, reaction time, global cognitive function, memory, and executive function. RESULTS: Ten articles with a total of 920 participants were included. Static balance (p=0.0009), dynamic balance (p=0.0008), fall risk (p<0.00001), and agility (p=0.02) improved more in the intervention group than in the control group. However, SSE did not seem to exert beneficial effects on cognitive function. CONCLUSION: In older adults, SSE provided beneficial effects on motor function, including static and dynamic balance, risk of falls, and agility. However, positive effects on cognitive function were not observed and require further investigation.
