Importance: More research is required to clarify the association between physical activity and health in "weekend warriors" who perform all their exercise in 1 or 2 sessions per week. Objective: To investigate associations between the weekend warrior and other physical activity patterns and the risks for all-cause, cardiovascular disease (CVD), and cancer mortality. Design, Setting, and Participants: This pooled analysis of household-based surveillance studies included 11 cohorts of respondents to the Health Survey for England and Scottish Health Survey with prospective linkage to mortality records...

In later life, people are faced with a multitude of risky decisions that concern their health, finance, and personal security. Older adults often exercise caution in situations that involve risk. In this research, we asked whether older adults are also more responsive to warnings about potential risk. An answer to this question could reveal a factor underlying increased cautiousness in older age. In Study 1, participants decided whether they would engage in risky activities (e.g., using an ATM machine in the street) in four realistic scenarios about which participants could be expected to have relevant knowledge or experience...

Being overweight is a major risk factor for developing knee osteoarthritis (OA). The purpose of the current study was to: (a) determine participant adherence to a quadriceps exercise and weight management program after completion of the intervention; and (b) examine whether a quadriceps exercise and weight management program can reduce knee pain and improve knee function and weight loss in 40 community-dwelling overweight Thai older adults with knee OA at 6- and 12-month follow up. Twenty-nine (76.3%) participants completed at least 75% of the program...

This cluster-randomized trial was designed to determine the efficacy of a 6-month exercise-nutritional supplement program (ENP) on physical function and nutritional status for older adults and the feasibility of implementing this program in a senior living setting. Twenty senior living facilities were randomized to either a three day per week group-based ENP led by a trained facility staff member or a health education program (SAP). Participants (N=121) completed a short physical performance battery, 400 meter walk, handgrip strength test, and mini-nutrition assessment...

Regular exercise is promoted as a therapeutic strategy for age-associated endothelial dysfunction. Improvements in endothelial function are observed with endurance exercise in older men, but are diminished or absent in older women. This review examines the hypothesis that sex hormones modulate vascular adaptations to exercise training by influencing antioxidant defense systems, mitochondrial function, oxidative stress, and intracellular signaling.

The senior population in Hawai'i is growing at a dramatic pace. In the older population, falls and fall-related injuries are leading causes of morbidity and mortality. Moreover, the health care costs for falls are very high. The State of Hawai'i has taken measures to prevent falls through the promotion of medication reviews, vision checks, home assessments, and exercise. However, current published examinations of fall preventive measures have been insufficient, and more research is needed to confirm risk factors, effectiveness of preventive measures, and to explore future objectives...

Our study examined the relationship between habitual high levels of vigorous physical activity on large and small artery compliance via radial artery pulse wave analysis. Eighty-three healthy men (n = 44) and women (n = 39), aged 18-78 years, were recruited as habitually less active (light-to-moderate exercise ≤3 times/wk) or habitually highly active (vigorous exercise ≥5 times/wk). A multivariate analysis of variance revealed a significant interaction of age and activity level; habitual vigorous activity was associated with greater compliance in large and small arteries in older adults (40-78 years) and younger adults (18-22 years)...

BACKGROUND: Physical inactivity ranks as a major contributing factor in the development and progression of chronic disease. Lifestyle interventions reduce the progression of chronic disease, however, compliance decreases over time and health effects only persist as long as the new lifestyle is maintained. Telephone counselling (TC) is an effective way to provide individuals with ongoing support to maintain lifestyle changes. Remote physical activity monitoring and feedback (RAMF) via interactive technologies such as activity trackers and smartphones may be a cost-effective alternative to TC, however, this comparison has not been made...

BACKGROUND: Change in cognitive ability is a commonly reported side effect by breast cancer survivors (BCS). The underlying etiology of cognitive complaints is unclear and to date there is limited evidence for effective intervention strategies. Exercise has been shown to improve cognitive function in older adults and animal models treated with chemotherapy. This proof-of-concept randomized controlled trial (RCT) tested the effect of aerobic exercise versus usual lifestyle on cognitive function in postmenopausal BCS...

BACKGROUND: Improvements in cognition often accompany fitness improvements in older adults, and research suggests insulin-like growth factor 1 (IGF-1) may influence this association. No prior work has examined this in mild cognitive impairment (MCI). We predicted that IGF-1 would moderate the relationship between cognition and aerobic endurance improvement, such that greater baseline IGF-1 would accompany a stronger relationship between cognition and aerobic endurance change. METHOD: Twenty-seven individuals with MCI completed assessments of aerobic endurance (2-minute step test [2MST]) and global cognition (Modified Mini-Mental State [3MS]) before and after a 6-month period of twice-weekly exercise...

BACKGROUND: Self-perceived uselessness is associated with poor health and high mortality among older adults in China. However, it is unclear which demographic, psychosocial, behavioral and health factors are associated with self-perceived uselessness. METHODS: Data came from four waves (2005, 2008, 2011 and 2014) of the largest nationwide longitudinal survey of the population aged 65 and older in China (26,624 individuals contributed 48,476 observations). This study aimed to systematically investigate factors associated with self-perceived uselessness based on the proposed REHAB framework that includes resources (R), environments (E), health (H), fixed attributes (A) and behaviors (B)...

: Background/Study Context: Whereas computer-assisted cognitive rehabilitation (CR) programs show promise as tools for improving cognition in certain populations, there is not a consensus regarding their efficacy. This study focuses on restorative CR, a treatment designed to improve cognitive functioning affected by progressive brain changes due to disease or aging, through computer-assisted cognitive exercises. The purpose of this study was to investigate the efficacy of a computer-assisted restorative CR intervention for improving cognitive functioning in older rehabilitation patients with relatively mild cognitive deficits...

BACKGROUND: frailty impacts older adults' ability to recover from an acute illness, injuries and other stresses. Currently, a systematic synthesis of available interventions to prevent or reduce frailty does not exist. Therefore, we conducted a scoping review of interventions and international policies designed to prevent or reduce the level of frailty in community-dwelling older adults. METHODS AND ANALYSIS: we conducted a scoping review using the framework of Arksey and O'Malley. We systematically searched articles and grey literature to identify interventions and policies that aimed to prevent or reduce the level of frailty...

PURPOSE OF REVIEW: Memory loss can be due to a wide variety of causes. We provide new information about the biology of common genetic and acquired causes of memory loss in older adults. RECENT FINDINGS: New data are available about the genetics of Alzheimer disease (AD), dementia with Lewy bodies (DLB), and frontotemporal dementia. Amyloid PET, FDG-PET, and MRI have improved our understanding of how mild cognitive impairment evolves to AD. Several studies have shown links between concussion and chronic traumatic encephalopathy...

The circadian clock regulates many physiological functions including physical activity and feeding patterns. In addition, scheduled exercise and feeding themselves can affect the circadian clock. The purpose of the present study was to investigate the relationship between physical/feeding activity and expression of clock genes in hair follicle cells in older adults. Twenty adult men (age, 68 ± 7 years, mean ± SE) were examined in this cross-sectional study. Prior to hair follicle cell collection, the participants were asked to wear a uniaxial accelerometer for one week...
