Special Issue Information

Dear Colleagues,

Population aging is one of the primary challenges facing contemporary societies, with profound implications for public health, the economy, and quality of life. In this context, healthy lifestyles are essential strategies to promote healthy aging and mitigate the adverse effects of biological aging. 

Scientific evidence has shown that lifestyle modifications in factors such as diet and physical activity have the potential to reduce the risk of age-related disorders, disabilities, or chronic diseases that promote increased physical and/or cognitive frailty. Multimodal interventions on diet, physical activity or exercise, sleep, etc., are used to promote healthy aging; however, there is still a lack of evidence on the efficacy and mechanisms of multimodal interventions on age-related conditions and disorders such as frailty and sarcopenia, cognitive impairment, and chronic diseases.

This Special Issue of Nutrients, "Healthy Diet, Physical Activity and Aging", aims to submit original research and literature reviews on these topics.

With a sustained increase in lifespan, understanding and promoting the synergies between a healthy diet and physical activity is crucial to changing the paradigm of aging, taking a preventive rather than a reactive approach. These interventions can improve longevity and preserve quality of life and autonomy in older people.

Background/Objectives: Exercise is a key nonpharmacological strategy for the management of sarcopenic obesity (SO), characterized by low muscle mass and excess fat. However, long-term interventions and specific modalities, such as power training (PT), remain unexplored in this population. Methods: In this 32-week randomized controlled trial, 40 community-dwelling women (mean age: 77.0 ± 6.8 years) with sarcopenic obesity (per the EWGSOP2 and ESPEN criteria) were assigned to power training (PT), multicomponent training (MT), or a non-exercise control group (CG). Body composition, strength, and function were assessed pre- and post-intervention using within- and between-group analyses with effect size estimation. Nutritional intake was evaluated at baseline. Results: Significant pre–post intervention between-group differences were observed in appendicular skeletal muscle mass index (ASMI; p = 0.039), body fat percentage (BF%; p = 0.002), visceral fat (VF; p = 0.044), appendicular muscle mass (ASM; p = 0.021), gait speed (GS; p = 0.018), timed up and go test (TUG; p = 0.005), five-times sit-to-stand test (5STS; p < 0.001), and Short Physical Performance Battery (SPPB; p = 0.002). Large effect sizes (Cohen’s d > 0.8) were found in the PT group for all these variables. Post hoc analyses indicated that PT was significantly superior to MT in improving 5STS (p = 0.005) and TUG (p = 0.025). Notably, 35.7% of the PT participants no longer met diagnostic criteria for SO after the intervention. Conclusions: PT was more effective than MT and the CG in improving muscle mass, reducing fat, and enhancing functional performance in older women with SO. These findings support PT as a feasible and promising intervention. Full article
