Muscle sympathetic nerve activity at rest increases with age in humans. The respective influences of the aging process per se and gender on this increase and whether age and gender effects on muscle sympathetic nerve activity can be identified with plasma norepinephrine concentrations, however, have not been established. To examine these issues, nine young women (aged 24 +/- 1 years; mean +/- S...
BACKGROUND AND PURPOSE Estimating age- and sex-specific population attributable risks (PARs) of major risk factors for stroke may be a useful strategy to identify risk factors for targeting preventive strategies. METHODS For this case-control matched study, consecutive patients aged 18-90 years and admitted to nine nationwide hospitals with acute ischemic stroke between December 2008 and June...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Objectives: The purpose of this study was to compare the static balance in active and inactive adult and elderly men. Methods & Materials: 55 active adult and elderly men and 49 inactive adult and elderly men participated in this cross sectional- comparative study. Static balance was measured by stork stand test with opened and closed eye. Gait velocity (time) in active subjects was measured...
Introduction: Several studies indicate that peak bone mass, reached during the third decade in life, is an important determinant of osteoporosis later in life. Physical activity with dynamic loading of the bone is an important determinant of peak bone mass. Exercise especially before and during puberty is associated with increased bone density and cortical bone size in children and young adults...
We examined the effect of an age-related leftward shift in the force-frequency relationship on the comparative quadriceps fatigability of nine young (27 +/- 1 yr old) and nine old men (78 +/- 1 yr old) during low-frequency electrical stimulation. Two different protocols of intermittent trains (6 pulses on, 650 ms off) of electrical stimulation at 25% maximum voluntary contraction were performed...
the purpose of this study was to determine the effect of six-week high intensity interval training (hiit) on fibrinolytic factors (t-pa, pai-1 & t-pa/pai-1) in sedentary young men. eighteen inactive young men voluntarily took part in this study and were randomly divided into two groups including the experiment group (n: 9, age: 24.33 ± 1.41, height: 176.22 ± 4.91 and weight: 72.27 ± 6.59) and c...
Background and purpose: Aging is a set of progressive changes with gradual decrease in physiological function and homeostasis capacity that increases the risk of disease and mortality. the purpose of this study was to investigate the effect of interval training on indices of antioxidants in inactive older men. Methods and Materials: In this quasi-experimental study, 20 inactive elderly men wer...
OBJECTIVES Normative data for the SF-36 measure of health-related quality of life (HRQOL) exist for those over 25 years of age, based on data from the population-based Canadian Multicentre Osteoporosis Study (CaMos). CaMos recently recruited a sample of young Canadians aged between 16 and 24 years. The purpose of this study was to develop normative SF-36 data for this age group. METHODS After...
BACKGROUND Our purpose was to determine if aging had an influence on muscle blood flow independent of habitual physical activity levels. METHODS Blood flow was measured in the femoral artery by Doppler ultrasound after cuff occlusion of 10 minutes. Active and inactive older subjects (73 +/- 7 years) were compared to active and inactive young subjects (26 +/- 6 years). RESULTS Peak blood flo...
