to investigate the effect of exercise on cortisol responses and energy expenditure in obese and lean men, we measured the energy expenditure (ee) and salivary cortisol responses of six obese (age 22.83± 1.9 yr; vo2max,35.45±3.9 ml/min/kg; bmi 18.2±1.3 kg/m2) sedentary men. the protocol was running on a treadmill for 30 minutes with 65% maximal oxygen consumption. student t-test and one-way anov...

BACKGROUND N-terminal pro-brain natriuretic peptide (NT-proBNP) and high sensitivity Troponin T (hsTnT) are markers of cardiac injury used in diagnosis of heart failure and myocardial infarction respectively, and associated with increased risk of cardiovascular disease. Since physical activity is protective against cardiovascular disease and heart failure, we investigated whether higher levels ...

OBJECTIVES To compare physical activity (PA) subcomponents from EPIC Physical Activity Questionnaire (EPAQ2) and combined heart rate and movement sensing in older adults. METHODS Participants aged 60-64y from the MRC National Survey of Health and Development in Great Britain completed EPAQ2, which assesses self-report PA in 4 domains (leisure time, occupation, transportation and domestic life...

BACKGROUND Patterns of physical activity (PA), domestic activity and sedentary behaviours are changing rapidly in Asia. Little is known about their relationship with obesity in this context. This study investigates in detail the relationship between obesity, physical activity, domestic activity and sedentary behaviours in a Thai population. METHODS 74,981 adult students aged 20-50 from all re...

BACKGROUND Physical activity in leisure time seems to reduce the risk of low back pain, but it is not known whether occupational activity, as recorded in a representative working population, produces a higher or lower risk. OBJECTIVE To study associations between physical activity level at work and risk of chronic low back pain. METHODS Associations were examined in a Norwegian prospective ...

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...

Article received on April 28th, 2010 Article accepted on July 19th, 2010 Abstract Objective: To investigate the effect of physical activity in leisure time (LTPA) on the prognosis of patients two years after coronary artery bypass grafting (CABG). Methods: Cohort study with 202 elective CABG patients, mean age of patients was 62 ± 10 years, 134 (66%) men divided into sedentary and active accord...

UNLABELLED The purpose of this study is to evaluate whether the use of an activity monitor providing feedback has an effect on physical activity (PA) in young men. A population-based sample of 276 conscription-aged (mean = 17.9, SD = 0.7 years) men participated in a 3-month randomized controlled trial in Oulu in 2012. Participants were randomized to an intervention group (INT, N = 137) and a co...

BACKGROUND The relative contributions of decreases in maximal heart rate, stroke volume, and oxygen extraction and of changes in body weight and composition to the age-related decline in maximal oxygen uptake (VO2max) are unclear and may be influenced by sex and level of physical activity. METHODS AND RESULTS To investigate mechanisms by which aging, sex, and physical activity influence VO2ma...
