Trends in resting pulse rates in 9-11-year-old children in the UK 1980-2008

Little is known about whether levels of physical fitness, which is related to adiposity and physical activity (PA), have changed in children, particularly the progressive increase in childhood obesity levels. We aimed to examine the time trends in resting pulse rate (a marker of physical fitness) among UK children, in order to better understand the trends in levels of physical fitness in recent decades

Discordant blood flow velocity waveforms in left and right brachial arteries in growth-retarded fetuses

Objective: To determine if the increase in cerebral blood flow (''brain-sparing'' effect) with fetal hypoxemia is associated with discordant hemodynamics in the upper extremities
