abstract: background: diabetes is a major problem for health systems and physical activity is one of the most important modifiable and life style factors to management of diabetes. this study aimed to determine the status of physical activity (pa) in patients with type 2 diabetes based on trans theoretical model (ttm). methods: this study was conducted on 393 diabetic patient’s type 2 diabetes ...

BACKGROUND The Pregnancy Physical Activity Questionnaire (PPAQ) assesses physical activity practices of pregnant women. The purpose of this study was to identify specific pregnancy practices that were associated with a healthy gestational weight gain (GWG). METHODS Associations between PPAQ scores, pedometer steps, energy intakes (EI), energy expenditures (EE), and rate of GWG were assessed f...

BACKGROUND Physical activity (PA) is important for controlling childhood obesity, but a comprehensive PA model for school-aged children is lacking. OBJECTIVES Guided by the youth PA promotion (YPAP) model, this study estimated the direct and indirect effects of self-efficacy, enjoyment, parental influence, and environment on self-reported PA and pedometer steps. A secondary purpose was to exp...

The purpose of this study was to explore the relationship between objectively determined ambulatory activity and simple cardiorespiratory parameters (heart rate and blood pressure at rest and during submaximal exercise) in individuals who were stratified for self-reported participation (yes/any vs. no/none) in vigorous physical activity (PA). Ninety-eight subjects (African Americans: 7 M, 16 F;...

BACKGROUND Facilitating healthy levels of physical activity (PA) during chemotherapy is important for the psychosocial and physical health of breast cancer survivors. The primary objective of this feasibility study was to examine the effects of a broad-reach PA behavior change intervention among women with breast cancer receiving adjuvant chemotherapy.

Disturbed sleep is independently associated with adverse pregnancy outcomes. The primary aim of this research which tested Pender’s Model of Health Promotion was to evaluate the contribution of physical activity (PA) to sleep parameters in pregnant women, with pre-pregnant body mass index (BMI) as a confounder. Sleep and physical activity data were drawn from a parent study in which 29 sedentar...

Background: To establish a balance between work (physical exercise) and human, the aerobic capacity (VO2max) could be used as a measure. Assessing heart rate in association to physiological symptoms is the most commonly used tools for the assessment of fatigue during physical exercise. This study aimed to investigate the association between the aerobic capacity and the heart rate of workers fro...

background physical activity (pa) patterns during pregnancy have not been explored in depth and most previous studies lack assessment of variables such as type, frequency, duration and intensity of activity. objectives this study had two goals: 1) to analyze pa patterns during pregnancy according to weekly time spent on different types of activity; and 2) to determine women’s perception about h...
