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)
MiAMP1 is a recently discovered 76 amino acid residue, highly basic protein from the nut kernel of Macadamia integrifolia which possesses no sequence homology to any known protein and inhibits the growth of several microbial plant pathogens in vitro while having no effect on mammalian or plant cells. It is considered to be a potentially useful tool for the(More)
The objective of this study was to examine the effectiveness of a core endurance exercise protocol. Forty-five college-age rowers (age 21 +/- 1.0) were assigned to either a core training group [core group] (n = 25), which took part in a core endurance intervention exercise protocol, or to a control training group [control group] (n = 20), which was not(More)
STUDY OBJECTIVES To examine the ventilatory responses of prepubescent children to submaximal and peak exercise using appropriate allometric modeling to control for differences in body size. DESIGN Cross-sectional study of a representative sample of children. SETTING Middle schools (8 to 11 years) in Exeter, UK. PARTICIPANTS We studied 101 boys and 76(More)
The purpose of this study was to investigate the effects of two, three times a week, 8-week training programmes on the aerobic power and anaerobic performance of 30 prepubescent girls, with a mean age of 9.6 y. Peak oxygen uptake assessed by an incremental discontinuous treadmill test, and peak power in 5 s and mean power over 30 s estimated from a Wingate(More)
PURPOSE A walking media station was developed, which enables normally seated screen activities to be conducted whilst walking. This study tests feasibility of the walking media station and provides preliminary evidence of the acceptability of the device in the home environment. METHODS Twenty-nine healthy children (mean age 9.6 years) participated in the(More)
PURPOSE The purpose of this study was to provide RT3 accelerometer thresholds to distinguish nonambulation from ambulation, as well as distinguish between low, moderate, and vigorous intensity ambulation in Chinese children. METHODS Thirty-five 8- to 12-yr-olds completed a laboratory-based experiment to calibrate the RT3 device across a range of(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)
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)
