The physical literacy (PL) concept integrates different personal (e.g., physical, cognitive, psychological/affective, social) determinants of activity and has received growing attention recently. Although practical efforts increasingly adopt PL as a guiding concept, latest evidence shown that interventions often lack specification important theoretical foundations basic delivery information. Therefore, the goal present study was to develop an expert-based template supports researchers...

Circadian rhythms influence daily behavior, psychological and physiological functions, as well physical performance. Three chronotypes are distinguished according to the preferences people typically display for activity at certain times of day: Morning, Neither, Evening types (M-, N- E-types). The chronotype changes with age: eveningness tends be stronger in youth morningness older age. progressive shift toward during adolescence creates misalignment morning society schedules can lead a...

Dp was measured using an electro-mechanical towing device composition assessed bioelectrical impedance analyser. Body lengths circumferences were both standing simulated...

Military schools primarily aim to prepare young people for the admission procedures of military academies. In this specific environment, high overall load can generate burnout in cadets and consequent failure achieve scholastic objectives. The present study investigated how a training protocol based entirely on internal reflective approach military-type school context affects participants’ physical efficacy, efficiency, psychological outcomes. For study, 63 who were 17 years old from an...

Background: In physical activity, testing procedures generally require maximal efforts. They are not always administrable or appropriate (e.g., with beginners, elderly, in school); therefore, alternative submaximal might be more fitting. This study aimed to assess the criterion validity and reliability of tests based on perceptual variables used instead corresponding evaluate muscular endurance, flexibility, cardiorespiratory fitness. The sustainability this “educational” rationale achieve...

System Thinking is an actual construct supported by several scientific evidence that offer a perspective on how phenomena relate. Rhythm methodology, teaching-learning, and enjoyment in physical education are the main system elements we hypothesize interacting closely to determine direct or mediated effects motor creativity rhythmic perceptive capacity. Seventy-six elementary middle school students (8.9 ± 2.1 years) were randomly assigned two groups: a) intervention group received lesson...

One of the mechanisms responsible for enhancing muscular hypertrophy is high metabolic stress associated with a reduced oxygenation occurring during exercise, which can be achieved by reducing speed movement. Studies have tested that lowered muscle artificially induced an inflatable cuff, could provoke changes in prefrontal cortex oxygenation, hence, to central fatigue. It was hypothesized (1) exercising slow movement would result greater increase cerebral and decrease compared exercises...

The purpose of this study was to assess the effect prolonged sitting on vertical jump young basketball players. After a standard warm-up 15 minutes, players from five teams underwent countermovement (CMJ) and stiff leg (SL) tests (T1 time point). were repeated (T2 point) after participants spent 20 minutes under different conditions, one by each team: playing, sitting, standing, active while sitting. Sitting further resumed activity for two which CMJ SL repeated. Neither playing nor standing...

High-level physical performance in rhythmic gymnastics is influenced by numerous skills and anthropometric factors.
