the main purpose of this study was to determine which correlate, perceived motor competence or motor skill competence, best predicts girls' physical activity behavior.a sample of 352 girls (mean age=8.7, sd=0.3 yr) participated in this study. to assess motor skill competence and perceived motor competence, each child completed the test of gross motor development-2 and physical ability sub-scale...

Why are performance trade-offs so rarely detected in animals when their underlying physiological basis seems so intuitive? One possibility is that individual variation in health, fitness, nutrition, development or genetics, or 'individual quality', makes some individuals better or worse performers across all motor tasks. If this is the case, then correcting for individual quality should reveal ...

Transfer (i.e., the application of a learned skill in a novel context) is an important and desirable outcome of motor skill learning. While much research has been devoted to understanding transfer of explicit skills the mechanisms of skill transfer after incidental learning remain poorly understood. The aim of this study was to (1) examine the effect of practice schedule on transfer and (2) inv...

Learning to perform a complex motor task requires the optimization of specific behavioral features to cope with task constraints. We show that when mice learn a novel motor paradigm they differentially refine specific behavioral features. Animals trained to perform progressively faster sequences of lever presses to obtain reinforcement reduced variability in sequence frequency, but increased va...

results in the control group, barthel and fugl-meyer indices showed significant improvement (p = 0.01, p = 0.00), while in the experimental group, significant improvement in barthel and fugl-meyer indices and dynamometers has been observed (p = 0.01, p = 0.00, p = 0.007). conclusions rtms can improve hand muscle force and functions of patients with chronic hemiplegia, while conventional treatme...

BACKGROUND AND PURPOSE The most remarkable behavioral asymmetry is handedness. The preferred hand often has better performance, motor strength, nonpreferred hand. However, whether these components are associated with skill learning is not clear. METHODS We evaluated healthy right-handers by setting a series of motor-performance tasks including skill learning, grip strength, and speed. RESUL...

objectives: developmental coordination disorder (dcd) is a motor skill disorder which impacts upon a child, s ability to perform age-appropriate activity of daily living and academic performance. they have problems in gross & fine motors, their upper limb coordination are impaired, too. in this way, we decided to compare motors skills with botmp test in children with dcd and their normal peers....
