The Multistage 20-m Shuttle Run Test for Predicting VOPeak in 6-9-Year-Old Children: A Comparison with VOPeak Predictive Equations.

This study aimed (i) to verify if using and carrying a portable gas analyzer (PGA) constrained the performance of school children on the multistage 20-m shuttle run test (20mSRT), (ii) to verify which peak oxygen consumption (VOpeak) predictive equations have greater agreement with VOpeak values measured by direct oximetry using the 20mSRT. The study participants were 130 children ((67 boys (age 7.76 ± 0.

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.

Behavioral Regulation Sport Questionnaire: Gender and Sport Invariance in Portuguese Athletes.

This study aimed to analyze measurement invariance of the Behavioral Regulation Sports Questionnaire (BRSQ) across gender and four different sports. In addition, we examined nomological validity via basic psychological needs satisfaction. Participants totaled 1,812 Portuguese athletes (1,220 males and 592 females; aged 15-59 years, Mage = 17.

Can Interpersonal Behavior Influence the Persistence and Adherence to Physical Exercise Practice in Adults? A Systematic Review.

Motivation seems to be a fundamental indicator of long-term physical exercise adherence. Self-Determination Theory (SDT) argues that social environment plays a central role in the satisfaction of basic psychological needs, which might directly affect the quality of one's motivation. Individuals who appear to be more self-determined tend to persist longer at certain behaviors.

The Behavioral Regulation in Exercise Questionnaire (BREQ-3) Portuguese-Version: Evidence of Reliability, Validity and Invariance Across Gender.

This study has as prime objective to analyze the psychometric properties of the Behavioral Regulation Exercise Questionnaire (BREQ-3) in a sample of Portuguese exercisers and invariance across gender. Two independent samples (448 calibration; 374 validation), aged between 16 and 78 years ( = 40.29; = 16.

Perceived Effort in Football Athletes: The Role of Achievement Goal Theory and Self-Determination Theory.

This study examined the motivational determinants of athletes perceived effort in football considering the four-stage motivational sequence at the contextual level proposed by Hierarchical Model of Intrinsic and Extrinsic Motivation: task-involving climate, basic psychological needs, self-determined motivation (SDM), and perceived effort. Additionally, SEM multi-group analysis across different age-groups (U15, U17, U19, and U21 years) and serial mediation of basic psychological needs (BPNs) and SDM on the task-involving motivational climate and the perceived effort were also analyzed. Two independent samples of male football athletes ( = 403, = 403), aged 13-20 years were enrolled in this study.

Determinants and Reasons for Dropout in Swimming -Systematic Review.

The present research aims to systematically review the determinants and reasons for swimming dropout. The systematic review was conducted through electronic searches on the Web of Knowledge and PsycInfo databases from 2 February to 29 July 2015, using the keywords dropout, withdrawal, motives, reasons, sport, framework-theories, motivation, swim*, review, attrition and compliance. Fifteen studies were found and six were fully reviewed and its data extracted and analysed.

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.

Reasons for dropout in swimmers, differences between gender and age and intentions to return to competition.

Background: This study's main purpose was to analyze reasons for dropout in competitive swimmers and differences between gender and age groups. The influence of dropout on swimmers intentions to return to competition, invariance across gender and validation of Questionnaire of Reasons for Attrition were also analyzed.

Methods: Study 1 - 366 athletes participated (N.

Cross-Cultural Validation of the Basic Psychological Needs in Physical Education Scale between Portugal and Brazil Samples.

The main propose of this study is the cross-cultural validation of the Basic Psychological Needs in Physical Education Scale among Portugal and Brazil samples, through the study of measurement model invariance. Participated in this study, two independent samples, one with 616 Portuguese students, of the 2nd and 3rd basic grade of public school, aged between 9 and 18 years old and another with 450 Brazilian students, from 1st, 2nd and 3rd middle grade of public and private school, aged between 14 and 18 years old. The results support the suitability of the model (three factors, each one with four items), showing an adequate fit to the data in each sample (Portugal: χ2 = 203.

Self-Determination and Physical Exercise Adherence in the Contexts of Fitness Academies and Personal Training.

This research aimed to analyze the validity of the relations hypothesized by the theory of self-determination in predicting adherence to physical exercise in fitness academy users and subjects following personal training. A total of 588 persons from Pelotas / RS / Brazil (405 gym users and 183 subjects following personal training) completed the Portuguese version of the three questionnaires, i.e.

Behavioral regulation assessment in exercise: exploring an autonomous and controlled motivation index.

The main purpose of this study was to examine the psychometric properties of the Portuguese version of the Behavioral Regulation in Exercise Questionnaire (BREQ-2) and to test the hypothesis that the different types of behavioral regulation can be combined on a single factor to assess autonomous and controlled motivation. Data were collected from 550 members of private fitness centres who ranged in age from 14 to 69 years. The analysis supported an 18-item, 5-factor model after excluding one item (S-B chi2 = 221.

Validation of the Basic Psychological Needs in Exercise Scale in a Portuguese sample.

In line with self-determination theory (SDT: Deci & Ryan, 1985, 2002) the satisfaction of the basic psychological needs for autonomy, competence, and relatedness has been identified as an important predictor of behavior and optimal functioning in various contexts including exercise. The lack of a valid and reliable instrument to assess the extent to which these needs are fulfilled among Portuguese exercise participants limits the evaluation of causal links proposed by SDT in the Portuguese exercise context. The aim of the present study was to translate into Portuguese and validate the Basic Psychological Needs in Exercise Scale (BPNES: Vlachopoulos & Michailidou, 2006).
