The purpose of this study was to examine whether the addition of a motor component to video gaming alters energy consumption. To address this problem we used an experimental manipulation design with 9-13 year olds incorporating 'seated video game' and 'activity enhanced video game' conditions, whilst allowing snacks ad libitum. No difference in snacking(More)
The main purpose of this study was to investigate whether rehearsal, defined as the tendency to recurrently ruminate over upsetting aversive experiences, had an effect on pedometry reactivity. A total of 156 Hong Kong Chinese children aged 9-12 years were recruited. Participants completed the Rehearsal Scale for Children-Chinese (RSC-C; Ling, Maxwell,(More)
BACKGROUND This study was designed to investigate the relation between health-related physical fitness and weight status in Hong Kong adolescents. METHODS 3,204 students aged 12-18 years participated in the Hong Kong Student Obesity Surveillance (HKSOS) project in 2006-2007. Anthropometric measures (height, weight) and health-related fitness (push-up,(More)
Physical activity and sedentary behavior are central components of lifetime weight control; however, our understanding of dimensions of these behaviors in childhood is limited. This study investigated free-living activity pattern characteristics and the individual variability of these characteristics in 84 lean and obese Chinese children (7-9 y) during the(More)
Non-exercise physical activity (NEPA) is an important part of energy expenditure. This study aimed to investigate the prevalence of exercise and NEPA among adolescents. In the HKSOS project 2006-2007, the proportions of Hong Kong Chinese adolescents (N=32,005) achieving 60-minute exercise and 60-minute NEPA per day were analyzed. Exercise was defined as(More)
Roger (1997) defined rehearsal as "the tendency to rehearse or ruminate on emotionally upsetting events" (p. 71). The Rehearsal Scale for Children-Chinese (RSC-C) was developed from the original 14-item Rehearsal Scale of the Emotion Control Questionnaire (Roger & Nesshoever, 1987) after translation and modification for Hong Kong Chinese preadolescents(More)
BACKGROUND Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between(More)
This study examined the association between propensity for emotional rehearsal, body image self-perception and weight status in Chinese Hong Kong pre-adolescents. Children 8-12 years of age (n = 278) completed measurement of body mass index, body image and emotional rehearsal. Multinomial regression analyses revealed that body mass index was positively(More)
Background: The development of active gaming offers a choice for children to be physically active whilst participating in an activity that is enjoyable and highly valued. Children expend energy when they play activity enhanced video games, yet little is known about their choice when given active alternatives over seated play.
BACKGROUND There is increasing evidence that continuous activation of the hypothalamic-pituitary adrenal axis and the central sympathetic nervous system contributes to the pathogenesis of central adiposity via increased psychological stress. The purpose of this study was to examine the link between central adiposity and the propensity for Chinese children(More)
