The effects of a single 3-mg dose of melatonin on the postural control and cognitive performance of community-dwelling older adults were documented. The testing involved stepping down while performing a cognitive task (a Stroop test). Thirty-four older adults were recruited. Immediately before and 1 hr after taking a dose of melatonin, they completed a single-leg standing task after stepping down with and without a simultaneous Stroop test, and a double-leg standing task. The findings indicated a statistically significant increase in sway area under the dual-tasking condition after taking melatonin (p = ...

Routine physical activity is important for everyone and most urban areas have an infrastructure of neighborhood parks that are intended to serve as a setting for recreation and leisure. However, parks are not used proportionally by all age groups, genders and socio-economic groups. This paper explores factors associated with park use by different age and gender groups in low-income neighborhoods in Los Angeles, CA. We found that women's visits to parks generally centered around children, while men's visits were more likely to be associated with their own physical activity...

Exercise is effective in preventing falls amongst older adults. However, few studies have included people living with dementia and their carers and explored their experiences. The aim of this paper is to explore what affects the acceptability of exercise interventions to better meet the needs of people with dementia and their carers as a dyad. Observations, field notes containing participants and instructor's feedback, and focus groups with 10 dyads involved in Tai Chi classes for 3 or 4 weeks in two sites in the South of England were thematically analysed to understand their experiences...

The aim of this study was to verify if older adults would benefit from a self-controlled schedule of knowledge of performance (KP) in the motor skill learning. The study's participants included 22 women and 18 men, with an average age of 68 years (SD = 2.95 years). These were divided into two groups: "Self", in which participants had control over when they received KP, and "Yoked", in which participants received KP in a paired manner with the Self group. The learning task was golf putting...

According to ecological models of behaviour, the physical environment can influence physical activity engagement via a series of mediating and moderating processes. The present study tested such a model to identify factors relevant to older people's engagement in moderate-to-vigorous physical activity (MVPA). Sociodemographic, psychological, physical, and environmental factors were assessed in 432 Western Australians aged 60+ years. MVPA was measured objectively using accelerometers. No environmental variables were related to engagement in MVPA either directly or indirectly...

Stroke results in low physical activity, high sedentary behaviour (SB), and elevated C-reactive protein (CRP), which are associated with stroke recurrence. This study examined the association between physical activity, SB, and CRP in stroke. CRP data from 185 stroke survivors (mean age 65 years) from the National Health and Nutritional Examination Survey 2009-2010 were analyzed using weighted regression analysis. There was an interaction between physical activity and SB on CRP [estimated-β -0.079, 95% CI (-0...

Declining physical function is common among aging adults, however physical activity may decrease the rate of functional loss among adults with or at risk of developing osteoarthritis. Previous studies on this topic used subjective measures of physical activity and were subject to higher selection bias. This study employed propensity score matching techniques to reduce selection bias when measuring the association between objectively-measured physical activity and future physical function. 687 participants of the Osteoarthritis Initiative were included in either a physically active group (n=280) or a physically inactive group (n=407) according to baseline accelerometer data...

Older adults are often considered more vulnerable to environmental factors than are younger adults. We examined whether the associations of objectively-measured environmental attributes (Walk Score; street connectivity) with walking for transport differed between younger- (25-44 years), middle- (45-64 years), and older-aged (65-84 years) adults, using a large of Australian sample of 14,656. Walk Score and street connectivity were similarly associated with walking (any; 30+ min/day) in all age groups. Contrary to commonly held views, the study did not find any evidence suggesting that older adults may be more sensitive to their environment to get out and walk than are younger adults, at least for the environmental attributes examined in this study...

The potential benefits of Omega-3 fatty acids and branched-chain amino acids (BCAAs) supplements on exercise-induced apoptosis are not clear. In a crossover randomized study, 11 men (age 62.8 ± 2.2 y) performed an acute bout of resistance exercise and underwent one-week supplementation with either 20 grams BCAA or 2700 mg omega-3/day. Subjects performed the same exercise after supplementation protocols. Following a three-week washout period, subjects switched groups. Circulating levels of soluble Fas ligand (sFasL), cytochrome c, Bax, BCL-2, and NF-kB were measured before and immediately after exercise sessions...

While football training may be a potent strategy for health promotion in older men, the considerable risk of injuries may constitute a barrier for referral of clinical populations. The current study explored the attitudes of men with prostate cancer on risk in the context of injuries related to participating in a community-based football program. Four videotaped focus group interviews, and three individual in-depth telephone interviews were carried out with men with prostate cancer (n=35; mean age 68.8). Thematic networks technique was used to derive the global theme Injury-induced reinforced masculinity comprising five sub-themes: "Part of the game", "A good story to tell", "Like boys again", "An old, carefree body", and "Camaraderie"...

The Timed Up and Go (TUG) Test is recommended by the U.S. Centers for Disease Control and Prevention as an easy to administer clinical test to evaluate a senior citizen's fall risk. Limited evidence has been presented in the literature validating the TUG Test. In this study we sought to assess correlations between the TUG Test and various balance markers utilizing the OptoGait system. Fifty-one healthy seniors completed randomized trials of the TUG Test and a Gait Test utilizing OptoGait photoelectric technology...

Cardiovascular disease (CVD) is a negative health outcome of Obstructive Sleep Apnoea (OSA). Risk factors associated with OSA development include low physical activity (PA), high body mass index (BMI), and increasing age (>50 years) and weight loss is usually recommended as treatment. This cross-sectional study examined the association between PA, BMI and OSA severity in manual workers. Fifty-five participants, (23 females, 32 males) mean age 55.2, were examined for OSA and completed a PA and anthropometric assessment...

BACKGROUND: Physical function is positively associated with subjective well-being in older adults from high-income nations. This study tests whether this association is evident in low- and middle-income countries. METHODS: Data were drawn from the Study on global AGEing and adult health, using nationally-representative samples of individuals over 50 years old from China, Ghana, India, Mexico, Russia, and South Africa. Participant interviews measured well-being (quality of life, mood, happiness) and physical function (grip strength, usual and rapid gait speed)...

This study compared functional demand (FD) between older and younger women walking at habitual and fast speed and determined strength thresholds necessary to maintain FD below 80%. FD was calculated by expressing walking flexion and extension joint torques, of the ankle, knee, and hip, as a percentage of maximal strength. Young had an average FD of 65% across joint actions and speeds, whereas older women had FD of 90%. In older women the greatest FD occurred in the hip musculature. The hip, knee and ankle extensor strengths required to maintain FD below 80% were 1...
