In urban low-income neighborhoods, child wellbeing is highly dependent on the school ecosystem. The schoolyard, specifically, provides opportunities for physical and social development during recess. The purpose of our study was to examine the impact of various schoolyard design features and green space on unstructured recess play behaviors accordi...
Background:
Green schoolyard renovations lead to immediate positive changes in moderate to vigorous physical activity (MVPA) and social behavior. This pilot study examines whether these benefits are equally distributed across gender and age and maintained 16 months postgreening.
Methods:
Physical activity and social interactions during recess we...
Introduction:
Nature exposure is associated with many wellbeing benefits. However, the influence of green space on the physical activity and social behaviors of children is not completely understood. The purpose of the study was to complete a stepwise impact evaluation of a large-scale playground greening project at a Title 1 elementary school in...
Hospital nurses play an important role in the nation’s short- and long-term patient care. At the same time, nurses often experience high levels of occupational stress and participate in low levels of physical activity (PA). The purpose of this study was to examine the impact of self-monitoring and a poster campaign on the PA behaviors of hospital n...
Background: Acute physical activity breaks lasting 10–60 min have been related to positive effects on student focus and academic performance. The aim of this study was to evaluate the impact of repeated brief physical activity-infused academic lessons (1–5 min) on student retention and on-task behavior. Methods: One class from each K-2 grade level...
This study examined the impact of iPad integration on performance in an undergraduate gross anatomy course. Two out of six course sections were assigned to one of the following conditions: control (no iPad, n = 61); limited access (laboratory iPads, n = 58); and unlimited access (personal iPads, n = 47). Student knowledge was assessed over time dur...
Background and Purpose: Limited access to physical activity resources contributes to elevated prevalence of obesity in Hispanic women living in low-income urban Los Angeles neighborhoods. Purpose: The purpose of this study was to determine the benefits of training with fitness zone equipment recently made available in public parks. Methods: Six ove...
Calcium-calmodulin/dependent protein kinase II (CaMKII), AMP-activated protein kinase (AMPK), and extracellular signal-regulated kinase (ERK1/2) have each been implicated in the regulation of substrate metabolism during exercise. The purpose of this study was to determine whether CaMKII is involved in the regulation of FA uptake and oxidation and,...
Data show that extracellular signal-regulated kinase 1/2 (ERK1/2) may be involved in the regulation of fatty acid (FA) uptake during muscle contraction via stimulation of CD36 translocation to the plasma membrane. The perfused hind limb model was used to determine (1) the importance of ERK1/2 signaling on contraction-induced FA uptake and (2) the e...
Muscle contraction activates AMP-activated protein kinase (AMPK) and extracellular signal-regulated kinase (ERK1/2), two signaling molecules involved in the regulation of muscle metabolism. The purpose of this study was to determine whether activation of AMPK and/or ERK1/2 contributes to the regulation of muscle fatty acid (FA) uptake and oxidation...
The purpose of this experiment was to investigate the role of extracellular signal-regulated kinase 1/2 (ERK1/2) signalling in the contraction-induced increase in muscle FA uptake.
Male Wistar rats (n = 41) were randomly assigned to either a resting or stimulated group. Within each group, animals were randomly assigned to receive PD-98059, an inhib...
To determine the role of AMP-activated protein kinase (AMPK) activation on the regulation of fatty acid (FA) uptake and oxidation, we perfused rat hindquarters with 6 mM glucose, 10 microU/ml insulin, 550 microM palmitate, and [14C]palmitate during rest (R) or electrical stimulation (ES), inducing low-intensity (0.1 Hz) muscle contraction either wi...
