Dynamic modulation transfer function: a method to characterize the temporal performance of liquid-cr

Dynamic modulation transfer function: a method to characterize the temporal performance of liquid-crystal displays.
A method to measure the dynamic modulation transfer function (DMTF) of a liquid-crystal display (LCD) is proposed to characterize its performance when rendering motion images. The method includes a measurement system to capture the temporal luminance variation of a […]

Children’s thermoregulation during exercise in the heat - a revisit.

Children\’s thermoregulation during exercise in the heat - a revisit.
The review revisits some child-adult differences relevant to thermoregulation and offers alternatives to accepted interpretations. Morphologically, children have a higher body surface area to mass ratio - a major factor in “dry” heat dissipation and effective sweat evaporation. Locomotion-wise, children are less economical […]

A pediatric perspective on inflammation and oxidative stress in response to exercise.

A pediatric perspective on inflammation and oxidative stress in response to exercise.
Dr. Oded Bar-Or was a giant in the area of pediatric exercise science and made numerous contributions to the health of children around the world. He also had a significant impact on a relatively new area of pediatric exercise science - […]

Non-invasive methods in paediatric exercise physiology.

Non-invasive methods in paediatric exercise physiology.
Oded Bar-Or\’s hypothesis that children may be “metabolic non-specialists”, even when engaging in specialized sports, has stimulated the study of paediatric exercise metabolism since the publication of his classic text Pediatric sports medicine for the practitioner in 1983. Evidence drawn from several methodologies indicates an interplay of […]

Acute physical activity and sports injuries in children.

Acute physical activity and sports injuries in children.
An increase in the physical activity of individuals has many health benefits, but a drawback of an increase in physical activity is the risk of related injuries. To reduce the short- and long-term effects in terms of social and economic consequences, prevention of physical activity […]

Pediatric exercise physiology symposium: a tribute to Oded Bar-Or.

Pediatric exercise physiology symposium: a tribute to Oded Bar-Or.
Dr. Oded Bar-Or was a pioneer in the study of children\’s physical activity, exercise, and health. His diverse research interests led to numerous scientific explorations on thermoregulation, aerobic and anaerobic capacity, physical activity, economy of movement, obesity, neuromuscular diseases, asthma, cystic fibrosis (CF), and […]

International conference on physical activity and obesity in children: summary statement and recomme

International conference on physical activity and obesity in children: summary statement and recommendations.
The increasing prevalence of obesity among the world\’s children and youth was the impetus for an international conference convened in Toronto, Canada, to examine issues related to physical activity and obesity in children (24-27 June 2007). The goal of the […]

Role of physiology and environmental factors on food intake control in boys.

Role of physiology and environmental factors on food intake control in boys.
To examine the hypothesis that physiologic regulation of short-term food intake (FI) in boys is affected by the interaction between physiological and environmental factors, four studies were conducted. The primary objectives were as follows: (i) to compare the effect of glucose […]

Metabolic syndrome in three ethnic groups using current definitions.

Metabolic syndrome in three ethnic groups using current definitions.
According to two current definitions, the prevalence of the metabolic syndrome (MetS) aamong black Haitians of Montreal was <20%, 30%-36% in Algonquin Indians of Quebec, and >45% in Mexicans of Oaxaca (all aged 35-60 y). Although phenotypes were different, high triglycerides and fasting dysglycemia […]
