Disparities in physical activity should be investigated in light of social justice principles. This article critically evaluates evidence and trends in disparities research within an ecologic framework, focusing on multilevel factors such a...

The results of recent studies indicate that in healthy men and women aged beyond approximately 65 years, the energy-producing pathways in skeletal muscle may combine with changes in motor unit behavior and muscle contractile properties to p...

Although the kinematics and dynamics of overarm throws, such as baseball pitching, have been studied extensively, the relations between these measures remain largely unknown. This review uses a three-dimensional analysis to characterize the...
The structure of variability in human walking and running is speed-dependent [0.03%]

The variability of gait in human walking and running is not random but shows self-similarity that is dependent on the speed of locomotion. The strength of the long-range correlations for each gait pattern follows a U-shaped function that is...

High-speed ultrasonography has revealed that, in human locomotion, the nature of fascicle and tendon length changes varies depending on the task, contraction intensity, and the muscles involved. The findings emphasize that the active fascic...

In mice, targeted deletion of the basic helix-loop-helix transcription factor, nescient helix-loop-helix 2 (Nhlh2), leads to adult-onset obesity and reduced physical activity. We propose the novel hypothesis that transcriptional activity by...
Does AMP-activated protein kinase negatively mediate aged fast-twitch skeletal muscle mass? [0.03%]

The activity of 5'-adenosine monophosphate (AMP)-activated protein kinase (AMPK), a negative regulator of cell size, is up-regulated with age in resting and overloaded fast-twitch skeletal muscle but not slow-twitch muscle. Here, we provide...

Studies that did not directly measure sedentary behavior often have been used to draw conclusions about the health effects of sedentariness. Future claims about the effects of sedentary, light, and moderate-to-vigorous activities on health ...
