Common traits of mobile computing are time critical tasks and interruptions that require multitasking. Essential for success of a mobile web task is quick and accurate performance. To facilitate performance in response to interruptions, an understanding of factors that influence multitashng during mobile computing is required. This study examines the effect of anticipation and origin (i.e. inst...

This paper describes some preliminary results from a 20-week study on the use of Compaq iPAQ Personal Digital Assistants (PDAs) by 10 senior developers, analysts, technical managers, and senior organisational managers. The goal of the study was to identify what applications were used, how and where they were used, the problems and issues that arose, and how use of the iPAQs changed over the stu...

<p>The current study investigated the validity of Greek version International Physical Activity Questionnaire-short form (IPAQ-SF, seven days recall period, Craig et al., 2003). Specifically, criterion and construct were examined in a sample 120 adults (<em>M</em> ± <em>SD</em> = 30.52 14.87 years). In addition, factorial internal consistency second 726 physically ...

We assessed commuting patterns in adolescents from 10 European cities and examined associations with physical activity (PA). A total of 3112 adolescents were included. PA was objectively measured with accelerometry. Commuting patterns and overall PA were self-reported using questions from the International Physical Activity Questionnaire modified for adolescents (IPAQ-A). Adolescents reported t...

Pedometer-determined physical activity (PA) levels in Belgian adults were provided and compared to PA scores reported in the International Physical Activity Questionnaire (IPAQ). The representative sample (N=1239) of the Belgian population took on average 9655 (4526) steps/day. According to pedometer indices 58.4% were insufficiently active. Steps/day differed significantly between gender (F = ...

PURPOSE This study explored definitions of sedentary behavior and examined the relationship between sitting time and physical inactivity using the sitting items from the International Physical Activity Questionnaire (IPAQ). METHODS Participants (N = 289, 44.6% male, mean age = 35.93) from 3 countries completed self-administered long- and short-IPAQ sitting items. Participants wore acceleromet...

Sedentary lifestyle is a major underlying cause of death, disease, and disability worldwide. This survey in 2006 aimed to estimate the current level of physical activity among 293 school and university teaching staff and 246 support staff working in the education sector in Dohuk city, Iraq. The short form of the international physical activity questionnaire (IPAQ) was used to estimate physical ...

BACKGROUND In the last decade, there has been increasing interest in the health effects of sedentary behavior, which is often assessed using self-report sitting-time questions. The aim of this qualitative study was to document older adults' understanding of sitting-time questions from the International Physical Activity (PA) Questionnaire (IPAQ) and the PA Scale for the Elderly (PASE). METHOD...

BACKGROUND An increasing body of evidence associates a high level of sitting time with poor health outcomes. The benefits of moderate to vigorous-intensity physical activities to various aspects of health are now well documented; however, individuals may engage in moderate-intensity physical activity for at least 30 minutes on five or more days of the week and still exhibit a high level of sitt...
