The debate about a possible relationship between aerobic fitness and motor skills with cognitive development in children has recently re-emerged, because of the decrease children's concomitant pressure schools to enhance performance. As literature young is scarce, we examined cross-sectional longitudinal spatial working memory attention preschool children.

Alpha-band activity (8-13 Hz) is not only suppressed by sensory stimulation and movements, but also modulated attention, working memory mental tasks, could be sensitive to higher motor control functions. The aim of the present study was examine alpha oscillatory during preparation simple left or right finger contrasting external internal mode action selection. Three conditions were examined using a precueing paradigm with S1 as preparatory S2 imperative cue: Full, laterality instructed S1;...

To assess the effect of a governmentally-led center based child care physical activity program (Youp’là Bouge) on motor skills. We conducted single blinded cluster randomized controlled trial in 58 Swiss centers. Centers were randomly selected and 1:1 assigned to control or intervention group. The lasted from September 2009 June 2010 included training educators, adaptation built environment, parental involvement daily activity. Motor skill was primary outcome body mass index (BMI), quality...

We performed a cross-sectional study in 450 nonreferred preschool children aged 4 to 6 years assess the association between hyperactivity/inattention with adiposity and lifestyle characteristics. Measurements included scores of hyperactivity/inattention, adiposity, objectively measured physical activity, television viewing, eating habits. Higher were associated lower percentage body fat, higher levels less time spent sedentary activity (all P ≤ .01). However, also more viewing healthy habits...

Abstract Contextual interference (CI)—the practice of tasks in a random rather than blocked order—is known to impair immediate performance while enhancing long-term learning and transfer. In simple aiming tasks, CI has been shown improve movement accuracy. However, whether these greater improvements extend unpracticed parameters, such as novel distances or the contralateral hand—a relationship informed by schema theory—remains unexplored. Additionally, non-sequential affect processes that...

The purpose of this study was to compare the accuracy a smartphone application and mechanical pedometer for step counting at different walking speeds mobile phone locations in laboratory context. Seventeen adults wore an iPphone6© with Runtastic Pedometer© (RUN), 3 (belt, arm, jacket) (YAM) waist. They were asked walk on instrumented treadmill (reference) various (2, 4 6 km/h). RUN more accurate than YAM 2 km/h (p < 0.05) = 0.03). At two devices equally accurate. precision increased speed...

Abstract Associative learning abilities vary considerably among individuals, with attentional processes suggested to play a role in these variations. However, the relationship between and individual differences associative remains unclear, whether variations reflect event-related potentials (ERPs) is unknown. This study aimed investigate by recording electrocortical activity of 38 young adults (18–32 years) during an task. Learning performance was assessed using signal detection index d’ ....

Over the last decades, a decline in motor skills and physical activity an increase obesity has been observed children. However, there is lack of data young We tested if differences according to weight or gender were already present 2- 4-year-old children.Fifty-eight child care centers French part Switzerland randomly selected for Youp'là bouge study. Motor assessed by obstacle course including 5 skills, derived from Zurich Neuromotor Assessment test. Physical was measured with accelerometers...

Anticipation is the ability to accurately predict future actions or events ahead of act itself. When attempting anticipate, researchers have identified that at least two broad sources information are used: contextual relating situation in question; and biological motion from postural cues. However, neural correlates associated with processing these different across groups varying expertise has yet be examined empirically. We compared anticipation performance electrophysiological activity...

The purpose of the study was to twofold: investigate gender-related differences in asymmetry aiming with preferred and non-preferred hand right-handed adults, examine effect spatial requirements task on these asymmetries. hypothesis that if cognitive functions are more asymmetrically localised men than women, one should observe greater left-right some variables women. Eleven eleven women were required aim fast accurately at three possible targets under a choice reaction time protocol....

Abstract The aim of this study was twofold: (a) analyze the development reaction time (RT) and movement (MT) for bimanual unimanual movements (b) investigate interaction age sex on changes in RT MT. Participants (5-, 8-, 11-year-olds) were asked to at target buttons under three conditions movement: unimanual, symmetrical, nonsymmetrical. As expected, RTs symmetrical shorter than nonsymmetrical 5-year-olds. By 8, still yielded longer movements, which no differed from each other. Regarding MT,...

Recent findings suggest that an acute physical exercise modulates the temporal features of EEG resting microstates, especially microstate map C duration and relative time coverage. Microstate has been associated with salience state network, which is mainly structured around insula cingulate, two brain nodes mediate cardiovascular arousal interoceptive awareness. Heart rate variability (HRV) dependent on autonomic balance; specifically, increase in sympathetic (or decrease parasympathetic)...

Exercise-induced fatigue affects the motor control and ability to generate a given force or power. Surface electroencephalography allows researchers investigate movement-related cortical potentials (MRCP), which reflect preparatory brain activity 1.5 s before movement onset. Although MRCP amplitude appears increase after repetitive single-joint contractions, effects of large-muscle group dynamic exercise on such pre-motor potential remain be described. Sixteen volunteers exercised 30 min at...

Abstract Inhibitory control (IC), the ability to suppress inappropriate actions, can be improved by regularly facing complex and dynamic situations requiring flexible behaviors, such as in context of intensive sport practice. However, researchers have not clearly determined whether how this improvement IC transfers ecological nonecological computer-based tasks. We explored spatiotemporal dynamics changes brain activity three groups athletes performing sport-nonspecific sport-specific Go/NoGo...

ABSTRACT Contextual interference (CI) enhances motor learning by practicing skill variations in a random rather than blocked order. It has been demonstrated that performing aiming distances order increased electrophysiological (EEG) markers of perceptual, attentional, and working memory processes. However, only the effect CI on these before training was assessed, without evaluating whether they would decrease with participants trained under compared to condition, indicating enhanced neural...

Abstract Contextual interference (CI) enhances learning by practicing motor tasks in a random order rather than blocked order. One hypothesis suggests that the benefits arise from enhanced early perceptual/attentional processes, while another posits better is due to highly activated mnemonic processes. We used high-density electroencephalography multi-scale analysis approach, including topographic analyses, source estimations, and functional connectivity, examine intertwined dynamics of...
