Background
Many patients do not maintain physical activity levels after completion of phase III exercise-based cardiac rehabilitation.
Design
This study determined the effect of an exercise consultation on maintenance of physical activity and cardiorespiratory fitness 12 months after completion of a phase III exercise programme. Seventy cardiac patients were randomized to ...
Purpose
To examine whether physical activity logbooks influence estimates of validity of 7-d recall physical activity questionnaires.
Methods
A convenience sample of 551 adults aged 18-75 yr wore an MTI accelerometer for seven consecutive days and were then randomly administered two of four 7-d recall physical activity questionnaires that varied in ...
Activity level (AL) is a highly salient feature of child behaviour that has been linked to developmental outcome. Twin studies of parent-rated, observer-rated and mechanically assessed AL in childhood find that AL is genetically influenced. Few studies, however, consider whether different methods of assessing AL have a shared genetic etiology. ...
Purpose
There currently is a paucity of well-validated instruments to quantitatively measure physical activity (PA) levels in patients with fibromyalgia syndrome (FMS). This study aims to determine the construct validity and test–retest reliability of two self-report physical activity questionnaires [short-form international physical activity questionnaire (s-IPAQ) and community health activities ...
Background
Although the positive effects of physical activity have been well established, the majority of people remain sedentary. Ecological models state that it is important to understand multiple influences on physical activity to develop appropriate interventions. Demographic and psychosocial correlates have been studied extensively, but physical environmental variables much less. ...
Background
The health benefits of physical activity for children are well established. Although objective measures of physical activity are increasingly used there is still a lack of adequate data on physical activity in children. Sex differences in physical activity have been consistently demonstrated and lower levels of physical activity in ...
Purpose
To evaluate the differences between Caucasians and non-Caucasians with regard to cardiorespiratory fitness, physical activity and obesity measures.
Methods
Four hundred and ten 9-year old children and 347 15-year old youths participated in a cross-sectional study as a part of the European Youth Heart Study. The non-Caucasians constituted 17% of the ...
Objective
To describe the levels of physical activity and energy intake in a sample of Bolivian Adolescents.
Setting
La Paz, September-October 2004. Methodology: 45 secondary school students (19 males; 26 females; mean age 15.6 SD 1.25) wear accelerometers (Actigraph-7164; http://www.theactigraph.com) during three days. Anthropometric measurements were registered. A semi-quantitative food frequency-questionnaire was used ...
Purpose The effect of physical activity during pregnancy on maternal and fetal health remains controversial and studies have yet to identify the optimal dose of physical activity associated with favorable pregnancy outcomes. The aim of this study was to develop and validate a pregnancy physical activity questionnaire (PPAQ).
Methods To ...
This study compared the determinants of physical activity in active and low-active African-American sixth grade students (N = 108, 57 F, 51 M). Objective assessments of physical activity over a seven-day period were obtained using the CSA 7164 accelerometer. Students were classified as active if they exhibited three or more 20-minute bouts of moderate to ...
