We investigated the relationship between sleep timing and the timing of the circadian rhythm of plasma melatonin secretion in a group of healthy young and older subjects without sleep complaints. The timing of sleep and the phase of the circadian melatonin rhythm were earlier in the older subjects. The relationship between the plasma melatonin rhythm and the timing of sleep was such that the ol...
Longitudinal studies suggest that hypertension in midlife is associated with cognitive impairment in later life. Cross-sectional studies are difficult to interpret because blood pressure can change with onset of dementia and the inclusion of subjects on treatment and with hypertensive end-organ damage can make analysis difficult. We examined cognitive performance in hypertensive and normotensiv...
Objectives: This study aimed to compare elderly fallers and non fallers by balance test under dual tasks conditions. Methods & Materials: This study was a analyse-comparative study. Subjects were chosen from three parks of Tehran. Subjects were 20 older adults with no history of falls (aged 72.60±5 years) and 21 older adults with a history of 2 or more falls in the last one year (aged 74.50±...
This study was designed to better understand the molecular mechanisms involved in the anabolic resistance observed in elderly people. Nine young (22 ± 0.1 years) and 10 older (69 ± 1.7 years) volunteers performed a one-leg extension exercise consisting of 10 × 10 repetitions at 70% of their 3-RM, immediately after which they ingested 30 g of whey protein. Muscle biopsies were taken from the vas...
Cognitive reserve (CR) is understood as capacity to cope with challenging conditions, e.g. after brain injury or in states of brain dysfunction, or age-related cognitive decline. CR in elderly subjects has attracted much research interest, but differences between healthy older and younger subjects have not been addressed in detail hitherto. Usually, one-time standard individual assessments are ...
The effect of age-related declines in proprioception and total knee replacement on postural control.
BACKGROUND An experiment was designed to examine the effects of a decrease in threshold joint position sense (TJPS) at the knee and ankle and of total knee replacement (TKR) on postural control in older adults. It was hypothesized that older adults with a decrease in TJPS and those who had undergone TKR would display increased center of pressure (COP) variance during quiet stance and late onset...
Objectives: The purpose of this study was to evaluate the concurrent validity of the Farsi version of Functional Gait Assessment (FGA), Timed Up & Go (TUG), and Gait Speed tests in Persian communitydwelling older adults. Methods: Subjects were 100 males in falling or no falling history group (50 subjects in each group). Subjects were community-dwelling adults aged 60-90 years who were living...
Objectives: The purpose of this study was to the relationship of physical activity and risk factors of coronary heart disease (CHD) in older men. Methods & Materials: The target population of this study was all older men in city of Kermanshah. Then, 123 healthy older men with mean age of 63.5±3.58 years, height 174.11±7.83 cm, weight 84.23±8.13 kg and body mass index 27....
OBJECTIVES To investigate the tolerability of tolterodine extended release (ER) in older subjects with overactive bladder (OAB). METHODS This was a retrospective analysis of pooled data from five large, randomised, double-blind, placebo-controlled trials. Subjects with OAB symptoms, including urinary frequency and urgency (and nocturia in two studies) with or without urgency urinary incontine...
This study was designed to compare the resting and exercise hemodynamics of older adults with moderate hypertension with those of age-matched normotensive controls. Thirty-one hypertensive (20 men, 11 women; mean age, 63.9 +/- 2.8 years) and 28 normotensive subjects (15 men, 13 women; mean age, 62.6 +/- 2.4 years) were studied. There were no differences between the groups in terms of body weigh...
