PURPOSE To compare the variation patterns of ADC and T2 values in different age and intervertebral disc (IVD) levels, thus to identify their sensitivities in assessing age and disc level related IVDs changes. MATERIALS AND METHODS The T2 and ADC values were recorded from 345 IVDs of 69 volunteers. Kendall's correlation analysis was used to identify the relationship between age and T2/ADC mean...

The present commentary provides a brief overview of and reflections on the joint findings of two reviews of the present evidence regarding correlates, predictors and/or determinants of sedentary behavior among youth and older adults published in the International Journal of Behavioral Nutrition & Physical Activity.In both reviews, the included studies were predominantly conducted in Europe, the...

BACKGROUND The reference values for cardiopulmonary exercise testing (CPET) available in Brazil were derived from a cycle ergometer in a sedentary and relatively small population. OBJECTIVE Provide reference values for CPET in Brazilians of both sexes, either sedentary or active. METHODS From 2006 to 2008, 3,992 CEPT of healthy individuals were selected from our laboratory. Athletes, smoker...

Arteriosclerosis with aging leads to central arterial stiffening in humans, which could be a prime cause for increased cardiac afterload in the elderly. The purpose of the present study was to assess the effects of 1 yr of progressive exercise training on central aortic compliance and left ventricular afterload in sedentary healthy elderly volunteers. Ten healthy sedentary seniors and 11 Master...

Mean serum cholesterol and triglyceride concentrations were higher for two groups of sedentary middle-aged and elderly men than for a group of physically-active, middle-aged farmers, all from rural Puriscal, Costa Rica. The mean serum cholesterol, triglyceride, and high-density lipoprotein (HDL)-risk factor levels of the three groups were all higher than the comparable US means. Dietary fat and...

PURPOSE OF THE STUDY This study aims to investigate the effects of a walking program on aerobic endurance and function in a sample of sedentary elderly people. DESIGN AND METHODS For this study, 126 sedentary individuals were recruited: 63 individuals (mean age = 74.1±6.0 years) for the control group and 63 (mean age = 72.0±4.5 years) for the intervention group. The intervention consisted of ...

background the purpose of this study was to determine appropriate intensity of activity with fatmax during incremental exercise in the active and sedentary male participants. material and methods in this study, 11 active male students(vo2max42.87±1.75ml.kg-1.min-1,bmi 21.40±1.01 kg.m2) and 9 sedentary male students(vo2max36.57±2.95ml.kg-1.min-1, bmi 24.28±1.83kg.m2) were selected as the active ...

In order to assess the relative influence of age, resting heart rate (HR) and sedentary life style, heart rate variability (HRV) was studied in two different groups. The young group (YG) consisted of 9 sedentary subjects aged 15 to 20 years (YG-S) and of 9 nonsedentary volunteers (YG-NS) also aged 15 to 20. The elderly sedentary group (ESG) consisted of 16 sedentary subjects aged 39 to 82 years...

Sedentary aging is associated with endothelial dysfunction and nitric oxide (NO) impairment. The aim of the present study was to assess the effects of regular physical exercise on nitrite/nitrate (NOx) concentrations and microcirculatory function in older men compared with young individuals. We measured NOx plasma concentrations and baseline and stimulated skin blood flow (SBF) by laser Doppler...

BACKGROUND Sporadic renal cell carcinoma (RCC) is rare in young adults. In the present retrospective study we reviewed clinicopathological features and disease specific survival rates in young patients (<= 45 years) with RCC and compared them to old patients (>= 75 years) with RCC. METHODS Between 1992 and 2005 a total of 1042 patients were treated for RCC at our institution. We found 70 pati...
