Perceptions of the Body and Body Dissatisfaction in Primary Education Children According to Gender and Age. A Cross-Sectional Study.

Body image (BI) is a trending topic of study since health problems derived from a negative perception of the body are increasing and affecting people of all ages, with an increasing incidence among children from the age of eight. The objective of this study was to evaluate the current perception of the body against the desired body and the degree of body satisfaction of Galician primary education students. A total of 355 students (167 boys (47%)) between 9 and 12 years old participated (mean = 10.

Gender Influences on Physical Activity Awareness of Adolescents and Their Parents.

The imbalances between the actual physical activity (PA) of adolescents and the subjective perception both they and their parents have in this regard can play an important role in perpetuating inactive lifestyles. The aim of this study is to analyse these discrepancies by considering gender as a conditioning factor. The participants in the study were 1697 adolescents, 1244 mothers and 1052 fathers in the educational communities of 26 secondary schools located in urban environments of the Autonomous Community of Galicia (Spain).

Gender Differences on Motor Competence in 5-Year-Old Preschool Children Regarding Relative Age.

The aim of this study was to evaluate the differences on motor competence between 5-year-old boys and girls and to investigate the existence of Relative Age Effect (RAE) on their motor competence. A total of 232 preschool children were evaluated of whom 134 (57.8%) were boys and 98 (42.

Parental assessment of physical education in the school curriculum: A brief report on the influence of past experiences as students.

The aim of this study was to analyse the relationship between parents' past experience as Physical Education (PE) students and the importance they give to PE within the school curriculum. Parents of 1834 teenagers from Spain and Portugal participated in the study (1834 fathers and 1834 mothers). An 11 item questionnaire was used for data collection.

What is the best position to place and re-evaluate an unconscious but normally breathing victim? A randomised controlled human simulation trial on children.

Background: Current resuscitation guidelines endorse placing the unconscious and normally breathing victims in the recovery position (RP), but this technique might hinder breathing evaluation.

Aim: To compare breathing evaluation and cardiac arrest detection: placing the victim in RP and checking breathing regularly, placing the victim in RP while re-evaluating breathing every minute, and placing the victim on his back, maintaining an open airway with the head-tilt-chin-lift technique and continuously checking breathing.

Methods: Schoolchildren aged 10-12 with no previous cardiopulmonary resuscitation (CPR) training, from three different primary schools were randomly allocated into groups to receive a CPR course involving one of the three strategies.

Reliability of Sargent Jump Test in 4- to 5-Year-Old Children.

We assessed the test-retest reliability of the Sargent jump (VJ) for vertical jumping performed by 4 and 5 years old pre-schoolers. The VJ was administered three times (familiarization, test, and retest) to 163 children (mean age: 4.48 ± 0.

[Analysis of the reliability and validity of three self-report questionnaires to assess physical activity among Spanish adolescents].

Objective: To analyse the reliability and validity of the Weekly Activity Checklist (WAC), the One Week Recall (OWR), and the Godin-Shephard Leisure Time Exercise Questionnaire (GLTEQ) in Spanish adolescents.

Methods: A total of 78 adolescents wore a pedometer for one week, filled out the questionnaires at the end of this period and underwent a test to estimate their maximal oxygen consumption (VO2max). The reliability of the questionnaires was determined by means of a factor analysis.

The effect of immediate post-training active and passive recovery interventions on anaerobic performance and lower limb flexibility in professional soccer players.

The capacity to recover from intense training, competition and matches is considered an important determinant in soccer performance. At present, there is no consensus on the effect of post-training recovery interventions on subsequent training session. The aim of this study was to determine the effectiveness of active (12 min submaximal running and 8 min of static stretching) and passive recovery (20 min sitting on a bench) interventions performed immediately after a training session on anaerobic performances (CMJ, 20 m sprint and Balsom agility test) and lower limb flexibility 24 h after the training.

The effect of playing tactics and situational variables on achieving score-box possessions in a professional soccer team.

The aim of this study was to analyse the influence of playing tactics, opponent interaction and situational variables on achieving score-box possessions in professional soccer. The sample was constituted by 908 possessions obtained by a team from the Spanish soccer league in 12 matches played during the 2009-2010 season. Multidimensional qualitative data obtained from 12 ordered categorical variables were used.

Tensiomyography of selected lower-limb muscles in professional soccer players.

Tensiomyography is a non-invasive method of neuromuscular assessment used to measure muscle action characteristics, muscle tone, and muscle fiber type, and provides information on acute and chronic responses of muscle to different training loads. The aims of the present study were: to analyse differences in muscle response and mechanical characteristics of two major muscles of the lower extremity in a large group of Spanish soccer players according to playing position, and to provide group norms against which clinical findings may be compared. Data were collected from 78 professional soccer players (age 26.

The effect of recovery strategies on contractile properties using tensiomyography and perceived muscle soreness in professional soccer players.

The capacity to recover from intense training and matches is considered an important determinant in soccer performance. At present, there is no consensus on the effect of posttraining recovery interventions on subsequent training session. The aim of this study was to determine the effectiveness of active (12 minutes of submaximal running and 8 minutes of static stretching) and passive recovery (20 minutes sit on a bench) interventions performed immediately after a training session on muscle contractile properties using tensiomyography (TMG) and perceived muscle soreness 24 hours after the training.

The influence of a congested calendar on physical performance in elite soccer.

The aim of this study was to investigate recovery via analysis of activity profiles in a professional soccer team over an intense period of matches. A total of 172 outfield players from 27 Spanish League matches played by a professional team during the 2005-2006 season were analyzed using a multiple-camera match analysis system. The dependent variables were the distance covered by players at different intensities.

Game location and team quality effects on performance profiles in professional soccer.

Home advantage in team sports has an important role in determining the outcome of a game. The aim of the present study was to identify the soccer game- related statistics that best discriminate home and visiting teams according to the team quality. The sample included all 380 games of the Spanish professional men's league.

Game-Related Statistics that Discriminated Winning, Drawing and Losing Teams from the Spanish Soccer League.

The aim of the present study was to analyze men's football competitions, trying to identify which game-related statistics allow to discriminate winning, drawing and losing teams. The sample used corresponded to 380 games from the 2008-2009 season of the Spanish Men's Professional League. The game-related statistics gathered were: total shots, shots on goal, effectiveness, assists, crosses, offsides commited and received, corners, ball possession, crosses against, fouls committed and received, corners against, yellow and red cards, and venue.
