Aging is a complex process of physiological and social changes that leads to various diseases. The number of elderly people in the world is increasing dramatically and it should be noted that rapid population aging represents a major public health burden. On the other hand, providing an appropriate and low-cost approach to control and prevent complications such as chronic diseases, physical dysfunction, and the geriatric syndrome is necessary. Also, numerous studies have shown that participation in physical activity and exercise training reduces the incidence of dysfunctional capacity, cardiovascular and metabolic disease, as well as the premature death rate in older adults. After plenty of precise observations about the role of exercise on aging-related diseases and geriatric syndromes articles, the benefits of exercise and physical activity in older adults will be more tangible. Therefore, the first purpose of the present review was to investigate the mechanisms of PA and exercises that are involved in the prevention of aging-related diseases and GS using current evidence (from 2015 onwards). Also, the purpose of this study was to provide an exercise guideline (aerobic and resistance training) based on recent evidence (from 2015 onwards). El envejecimiento es un proceso complejo de cambios fisiológicos y sociales que conduce a diversas enfermedades. El número de personas de edad avanzada en el mundo está aumentando drásticamente y cabe señalar que el rápido envejecimiento de la población representa una importante carga para la salud pública. Por otro lado, es necesario brindar un enfoque adecuado y de bajo costo para controlar y prevenir complicaciones como enfermedades crónicas, disfunción física y síndrome geriátrico. Además, numerosos estudios han demostrado que la participación en la actividad física y el entrenamiento físico reduce la incidencia de disfunciones, enfermedades cardiovasculares y metabólicas, así como la tasa de muerte prematura en los adultos mayores. Después de muchas observaciones precisas sobre el papel del ejercicio en los artículos sobre enfermedades relacionadas con el envejecimiento y síndromes geriátricos, los beneficios del ejercicio y la actividad física en los adultos mayores serán más tangibles. Por lo tanto, el primer propósito de la presente revisión fue investigar los mecanismos de actividad física y ejercicios que están involucrados en la prevención de enfermedades relacionadas con el envejecimiento y síndrome geriátrico utilizando la evidencia actual (de 2015 en adelante). Además, el propósito de este estudio fue proporcionar una guía de ejercicio (entrenamiento aeróbico y de resistencia) basada en evidencia reciente (de 2015 en adelante).

AbstractEnhancing physical activity promotes positive health trajectories throughout the life course. Physical activity should be tailored and graded to suit older adults’ capacities and needs and can be combined with rehabilitation interventions to manage geriatric syndromes and disability. This chapter provides a summary of current evidence about the role of physical activity for older adults, emphasizing nutritional aspects. We also present strategies to help health-care professionals to enhance physical activity participation.

Cognitive decline is a common feature of aging. Physical activity is a modifiable lifestyle factor that has been identified as positively impacting cognitive health of older adults. Here, we review the current evidence from epidemiological (i.e., longitudinal cohort) and intervention studies on the role of physical activity and exercise in promoting cognitive health in older adults both with and without cognitive impairment. We highlight some of the potential underlying mechanisms and discuss some of the potential modifying factors, including exercise type and target population, by reviewing recent converging behavioral, neuroimaging, and biomarker evidence linking physical activity with cognitive health. We conclude with limitations and future directions for this rapidly expanding line of research.

Physical activity is a promising strategy for dementia prevention and disease modification. Here, we provide a narrative review of the current evidence from epidemiological and intervention studies on the role of physical activity and exercise in promoting cognitive health in older adults both without and with cognitive impairment. We highlight some of the potential underlying mechanisms and discuss biological sex as a potential moderating factor. We conclude with limitations and future directions for this rapidly expanding line of research.

Physical activity and exercise have emerged as potential methods to improve brain health among older adults. However, there are currently no physical activity guidelines aimed at improving cognitive function, and the mechanisms underlying these cognitive benefits are poorly understood. The purpose of this narrative review is to present the current evidence regarding the effects of physical activity and exercise on cognition in older adults without cognitive impairment, identify potential mechanisms underlying these effects, and make recommendations for exercise prescription to enhance cognitive performance. The review begins with a summary of evidence of the effect of chronic physical activity and exercise on cognition. Attention then turns to four main biological mechanisms that appear to underlie exercise-induced cognitive improvement, including the upregulation of growth factors and neuroplasticity, inhibition of inflammatory biomarker production, improved vascular function, and hypothalamic-pituitary-adrenal axis regulation. The last section provides an overview of exercise parameters known to optimize cognition in older adults, such as exercise type, frequency, intensity, session duration, and exercise program duration.

Objectives. The aim of this study was to explore social engagement and social comparisons as mechanisms to increase physical activity among older adults. Methods. Participants (N = 60, mean age = 65.7) were randomly assigned to one of two conditions. Participants in the treatment condition used the application to track their daily walking steps and interact via text messages with their group members for 4 weeks. Participants in the control group used the application only to track their own walking steps. Outcome variables included mean weekly steps, exercise self-efficacy, and social engagement. Results. The results revealed that participants in the experimental condition significantly increased their mean weekly steps and social engagement from the pretest to the posttest whereas the control group did not. These effects were maintained at the 1-month follow up. Discussion. The study expands our understanding of the motivational role of social engagement and social comparison in increasing PA among older adults.

Alzheimer's disease is a chronic illness characterized by clinical cognitive impairment. A behavioral strategy that is being explored in the prevention of Alzheimer's disease is physical activity. Evidence from randomized controlled trials (RCTs) testing the effects of physical activity for cognitively normal older adults supports that physical activity benefits cognitive performance. Evidence from prospective studies supports a protective effect of physical activity with reductions in the risk of cognitive decline ranging from 28% to 45%. RCTs with cognitively impaired older adults also generally support positive effects with greater benefits evident for aerobic interventions. Research examining the potential moderating role of apolipoprotein E (APOE) has yielded mixed results, but the majority of the studies support that physical activity most benefits those who are at greatest genetic risk of Alzheimer's disease. Future directions for research are considered with an emphasis on the need for additional funding to support this promising area of research.

The role of dietary protein intake on muscle mass and physical function in older adults is important for the prevention of age-related physical limitations. The aim of the present study was to elucidate links between dietary protein intake and muscle mass and physical function in older women meeting current guidelines of objectively assessed physical activity. In 106 women (65 to 70 years old), protein intake was assessed using a 6-day food record and participants were classified into high and low protein intake groups using two Recommended Dietary Allowance (RDA) thresholds (0.8 g·kg−1 bodyweight (BW) and 1.1 g·kg−1 BW). Body composition, aerobic fitness, and quadriceps strength were determined using standardized procedures, and self-reported physical function was assessed using the SF-12 Health Survey. Physical activity was assessed by accelerometry and self-report. Women below the 0.8 g·kg−1 BW threshold had a lower muscle mass (p < 0.05) with no differences in physical function variables. When based on the higher RDA threshold (1.1 g·kg−1 BW), in addition to significant differences in muscle mass, women below the higher threshold had a significantly (p < 0.05) higher likelihood of having physical limitations. In conclusion, the present study supports the RDA threshold of 0.8 g·kg−1 BW of proteins to prevent the loss of muscle mass and emphasizes the importance of the higher RDA threshold of at least 1.1 g·kg−1 BW to infer additional benefits on constructs of physical function. Our study also supports the role of protein intake for healthy ageing, even in older adults meeting guidelines for physical activity.
