A framework is presented of how theoretical predictions can be tested across the expert athlete to disabled patient skill continuum. Common-coding theory is used as the exemplar to discuss sensory and motor system contributions to perceptual-motor behavior. Behavioral and neural studies investigating expert athletes and patients recovering from cerebral stroke are reviewed. They provide evidence of bi-directional contributions of visual and motor systems to perceptual-motor behavior. Majority of this research is focused on perceptual-motor performance or learning, with less on transfer...

BACKGROUND: Socioeconomic status (SES) is the most accurate predictor of academic performance in US schools. Third-grade reading is highly predictive of high school graduation. Chronic physical activity (PA) is shown to improve cognition and academic performance. We hypothesized that school-based PA opportunities (recess and physical education) would moderate the negative association between SES and third-grade reading. METHODS: Schools serving third-grade students were surveyed (N = 1279) for minutes/week of PA opportunities...

INTRODUCTION: The purpose of this study was to examine the effects of a short-term fast eccentric and ballistic complex training program on muscle power, rate of force development (RFD), muscle fiber composition and cross-sectional area (CSA). METHODS: Sixteen male physical education students were randomly assigned to either a training group (TG, n=8) or a control group (C, n=8). The TG followed a 6-week low volume training program, including fast eccentric squat training with an individually optimized load of 74±7% of maximal half-squat strength (1RM) twice per week and a ballistic training session with loaded (30% 1RM) and unloaded jump squats, once per week, all combined with unloaded plyometric jumps...

PURPOSE: The consensus is that physical activity (PA) and sedentary behavior (SB) are independent behaviors, but past findings suggest that they may be influenced by common underlying factors. To clarify this issue, we examined associations between enjoyment of PA and participation in both PA and SB in a large sample of 4th- to 12th-grade US youth. METHODS: A total of 18,930 students from 187 schools completed the youth activity profile, a self-report 15-item survey that assesses time spent in PA and SB in school and home settings...
