Repeatability of Brain Activity as Measured by a 32-Channel EEG System during Resistance Exercise in Healthy Young Adults.

Electroencephalography (EEG) is attracting increasing attention in the sports and exercise fields, as it provides insights into brain behavior during specific tasks. However, it remains unclear if the promising wireless EEG caps provide reliable results despite the artifacts associated with head movement. The present study aims to evaluate the repeatability of brain activity as measured by a wireless 32-channel EEG system (EMOTIV flex cap) during resistance exercises in 18 apparently healthy but physically inactive young adults (10 men and 8 women).

The Influence of an Enriched Sport Program on Children's Sport Motivation in the School Context: The ESA PROGRAM.

Purpose: Besides the evident positive effect on body development, physical activity has proven to boost executive functions, especially if the exercises are enriched with cognitive stimuli. Previous studies have shown that introducing challenging exercises in the physical activity routine can also enhance motivation. Therefore, enriching a physical education program with cognitively challenging exercises may also foster children's motivation during physical education classes, where the motivation is high at the beginning of the school year and low at the end of it.

Validation and adaptation of the Physical Activity Enjoyment Scale (PACES) in fitness group exercisers.

Background: Recently, Mullen et al. (2011) presented an 8-item version of the Physical Activity Enjoyment Scale (PACES) that provides a valid instrument for assessing enjoyment in physical activity. The present paper investigated the psychometric properties of a Portuguese adaptation of PACES.

Motivational determinants of physical education grades and the intention to practice sport in the future.

Unlabelled: Self-Determination Theory (SDT) is amongst motivational frameworks the most popular and contemporary approach to human motivation, being applied in the last decades in several domains, including sport, exercise and physical education (PE). Additionally, Achievement Goal Theory (AGT) has presented evidence of how contextual factors may influence student's behavior in this particular context. The main purpose of this study was to analyze the motivational climate created by the teacher in the classroom, students' satisfaction of Basic Psychological Needs (BPN), and how their behavioral regulation could explain PE grades and intention to practice sports in the future.

Effects of school-based interventions on motivation towards physical activity in children and adolescents: protocol for a systematic review.

Background: Recent studies have observed low levels of physical activity in children and adolescents worldwide. Physical activity interventions are increasingly carried out to counteract this development. The school environment is an ideal setting for such interventions to take place as large numbers of children and adolescents can be addressed.

Motivational Climate Sport Youth Scale: Measurement Invariance Across Gender and Five Different Sports.

The aim of this study was to analyze the psychometric properties of the Portuguese version of the Motivational Climate Sport Youth Scale (MCSYSp) and invariance across gender and different sports (swimming, soccer, handball, basketball, futsal). A total of 4,569 athletes (3,053 males, 1,516 females) from soccer (1,098), swimming (1,049), basketball (1,754), futsal (340), and handball (328) participated in this study, with ages between 10 and 20 years (M = 15.13; SD = 1.

Relationship between group cohesion and anxiety in soccer.

Group cohesion in sport is a widely spread theme today. Research has found cohesion to be influenced by several individual and group components. Among the cognitive variables that relate to cohesion we found competitive anxiety.
