Physical activity plays an important role for achieving healthy aging by promoting independence and increasing the quality of life. However, current guidelines for physical activity in older adults may be difficult to achieve in an older population. Indeed, there is evidence to suggest that increasing exercise intensity in older adults may be associated with greater reductions in the risk of cardiovascular disease and mortality. Therefore, the idea prescribing high-intensity exercise protocols such as high-intensity interval training and high-intensity resistance training becomes an intriguing strategy for healthy aging. Collectively, the literature review in this viewpoint will briefly focus on summarizing alternative/novel time-efficient approaches in physical activity toward healthy aging. Our goal is to hopefully open a discussion on possibly revising the current physical activity guidelines in older adults.

It has been suggested that gain-framed messages are more effective than loss-framed messages in promoting low-risk health behaviors such as physical activity. Because of a heightened health concern and possible medical complications, older adults with type 2 diabetes (T2D) may consider physical activity to be risky. This study examined whether a reverse message-framing effect would be found among older adults with T2D. The participants included 211 sedentary and older adults with T2D recruited from an outpatient clinic. The participants were randomly assigned to receive either gain-framed or loss-framed messages and wore an accelerometer to monitor their physical activity for 2 weeks. The participants who received loss-framed messages were more physically active than those who received gain-framed messages (β = 0.13, p = .033). This loss-frame advantage might be attributable to the heightened perceived risks among older outpatients with T2D and the temporarily activated prevention-focused orientation in a clinical setting.
