Contamination is commonly overlooked in randomized trials. The present study examined contamination (minutes of aerobic activity outside of exercise sessions) within an active control condition in a 6-month randomized exercise trial for older adults. We hypothesized that outside aerobic activity would be greater in the control condition compared to the intervention conditions. Participants (mea...

INTRODUCTION Regular physical activity can reduce age-related functional decline, as well people's risk for chronic diseases such as coronary heart disease, hypertension, colon cancer, and diabetes. The objective of this study was to estimate the level of participation in aerobic, muscle-strengthening, and flexibility activities among Americans aged 50 years or older. METHODS Using population...

OBJECTIVE To determine the relationship between change in physical activity level and change in directly measured maximal aerobic fitness in severely obese subjects participating in a 1-year lifestyle intervention, and to determine whether change in 6-min walk test (6 MWT) could be used as an indicator of change in aerobic fitness. METHODS Complete data on aerobic fitness (maximal oxygen cons...

Objective: The purpose of this study was to investigate the combined effect of aerobic activity and ginger supplementation on blood glucose and cardiovascular risk factors in overweight girls. Materials and Methods: In this semi-experimental study, 24 overweight female students were randomly divided into two groups; supplement group (n: 12, age: 25.88 (±0.46), Body Mass Index (BMI): 28.53 (±0.4...

purpose to translate long form, interview-administered international physical activity questionnaire (ipaq) from english to persian and evaluate its validity, reliability and reproducibility. methods a forward-backward translation procedure was followed to develop the persian version of the ipaq. a total of 218 respondents (53.7% women, aged 22–76 yr) completed the persian version in tehran, ir...

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...

abstract a previous study on agricultural drains in khuzestan province of iran has indicated that carbonate calcium is the main component of the deposited salts in drainage envelops. to investigate the process of precipitation of carbonate calcium under different conditions including chemical, bio-chemical, aerobic and an-aerobic, a through laboratory investigation on geotextile drain envelop w...
