OBJECTIVES The aims of this study were to design a best fit linear regression model to estimate VO2max (estimated VO2) and to compare the ability of VO2 values (measured and estimated) predicting cardiorespiratory complications in a series of patients undergoing lung resection for lung cancer. METHOD This was a prospective, observational study performed in 83 patients. Variables analyzed were...

BACKGROUND While the health benefits of physical activity are well established, little is known about health effects of physical activity programs initiated by employer. METHODS Background data and level of physical activity were collected by questionnaire among 78 men and 43 women working in road maintenance pre and post an 8-week physical activity motivational program. As a part of the prog...

BACKGROUND Physical activity (PA) has been identified as a central component in the promotion of health. PA programs can provide a low cost intervention opportunity, encouraging PA behavioral change while worksites have been shown to be an appropriate setting for implementing such health promotion programs. Along with these trends, there has been an emergence of the use of pedometers as a self-...

BACKGROUND AND OBJECTIVES PA is a multi-factorial behavior that is affected by interpersonal, intra personal, environmental and social factors. In this study we applied explanatory model to determine the total, indirect and direct impact of physical environment, personal factors and social support on PA among employed women. METHODS This study was a correlational cross-sectional study which w...

the purpose of this study was to examine the relation between daily steps and aerobic steps, and anthropometric variables, using the waist-to-hip ratio (whr) and waist-to-height ratio (whtr).the participants in this cross-sectional study were taken the measurements of by a trained anthropologist and then instructed to wear an omron pedometer for seven consecutive days. a series of statistical t...

coronary artery disease (cad) is the number one killer of adults in the iran. fibrinogen is cad risk factor that participation in both the atherogenic and thrombogenic processes. also playing a role in thrombosis and atherogenesis is homocysteine, as a risk factor for cad. long-term exercise training and physical activity favorably modified several of the conventional cad risk factors. no such ...

BACKGROUND Trials in primary care to increase physical activity (PA) typically experience poor recruitment rates and may not recruit those with lower PA levels and who are most in need of the intervention. Despite the well-publicised benefits of physical activity, the majority of adults in the UK remain inactive and, therefore, at greater risk of many health problems. Our aim was to investigate...

Physical performance is determined both by biophysical and physiological limitations and behavioral characteristic, specifically motivation. We applied an experimental evolution approach combined with pharmacological manipulation to test the hypothesis that evolution of increased aerobic exercise performance can be triggered by evolution of motivation to undertake physical activity. We used a u...
