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)
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)
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)
This study was designed to enhance understanding of the assessment and interpretation of the aerobic fitness of prepubertal children. Written informed consent to participate was obtained from 70% of the children in year six of the 15 state schools in the city of Exeter. Twenty-five per cent of the eligible children in each school were randomly selected from(More)
OBJECTIVE To examine energy expenditure and cardiovascular responses in children during seated and active gaming. DESIGN Comparison study. SETTING Children's Exercise Laboratory, University of Hong Kong. PARTICIPANTS Eighteen children (aged 6-12 years) recruited from local primary schools. MAIN EXPOSURE Active and seated computer games played by all(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)
Performance in sport takes place within a matrix of bio-cultural characteristics but boys' success in elite youth sport is underpinned by a range of age-and maturity-related physical and physiological variables which act in a sport-specific manner to influence performance. Stature, body mass, and muscle mass increase with growth and maturation and earlier(More)
OBJECTIVE The objective of this study was to test whether heart-rate feedback prompts increased physical activity (PA) in primary school students. METHODS A controlled trial with 210 9-11 year olds from subsidized Hong Kong Government primary schools was completed in December 2006. Schools were randomly assigned to one of three groups: Control (CG);(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)
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)
