Who can best report on children's motor competence: Parents, teachers, or the children themselves?
2018
Abstract Objective A positive perception of motor competence (MC) is important for children's health trajectory. It is purported that young children's perception is not well aligned with their actual ability. Alternative sources of perceptions are postulated from children's social context such as their parents or teachers. This study aims to analyse the associations among children's, parents' and Physical Education (PE) teachers' perception of children's MC and the children's actual MC, and whether these sources of information can report on children's actual MC. Design and method A convenience sample of 139 typically developed children (48.2% girls) from six schools participated in this cro…
El papel del profesor en la motivación y la salud mental de los estudiantes de educación física
2016
Resumen Introducción. La teoría de la autodeterminación sugiere que los sujetos con regulaciones autónomas mostrarán mayores niveles de funcionamiento óptimo que aquellos con regulaciones controladoras. Asimismo, la teoría ha defendido la importancia que tienen los factores sociales en los procesos motivacionales. En el contexto educativo, uno de los factores sociales que tiene un papel importante en la motivación de los estudiantes es el estilo interpersonal que utiliza el profesor cuando brinda instrucciones; por tanto, aquellos ambientes que fomenten la motivación autónoma serán importantes para el desarrollo óptimo y la salud mental de los estudiantes. Objetivo. Examinar si el grado en …

Influence of the distance in a roundhouse kick's execution time and impact force in Taekwondo.
2009
Taekwondo, originally a Korean martial art, is well known for its kicks. One of the most frequently used kicks in competition is Bandal Chagui or roundhouse kick. Excellence in Taekwondo relies on the ability to make contact with the opponent's trunk or face with enough force in as little time as possible, while at the same time avoiding being hit. Thus, the distance between contestants is an important variable to be taken into consideration. Thirty-one Taekwondo athletes in two different groups (expert and novice, according to experience in competition) took part in this study. The purpose of this study was to examine both impact force and execution time in a Bandal Chagui or roundhouse ki…

Relationships Between Personal Values and Leadership Behaviors in Basketball Coaches.
2018
Background: Based on the refined theory of basic individual values and transformational leadership theory, this study focuses on the associations between coaches' value priorities and their transformational leadership behaviors, exploring the potential mediation versus moderation effect of two alternative variables in this relationship: perceived club pressure or an autonomy supportive environment. Methods: Participants were 266 basketball coaches (85.7% men) from 17 to 66 years old (M = 32.82, SD = 9.2) from 119 different Spanish clubs. On average, they had worked for their current sport clubs for 5.02 years, and they had a mean of 11.10 years of experience. The coaches were all Spanish sp…
Examining Controlling Styles of Significant Others and Their Implications for Motivation, Boredom and Burnout in Young Swimmers
2021
The aim of the study was to examine the controlling style in two contexts of social influence: the team (i.e., coach and teammates) and the family (i.e., father and mother), as well as the mediational role of motivation (autonomous, controlled, and amotivation) and its relationship with boredom and burnout in young swimmers. To this end, 267 swimmers (140 girls and 127 boys) between 12 and 18 years of age (M = 14.26; SD = 1.61) were assessed. The results showed that in the team context, coaches’ controlling style directly promoted controlled motivation and boredom in their swimmers, and indirectly influenced burnout through the mediating role of swimmers’ controlled motivation. Teammates’ c…
Effect of Olympic Weight Category on Performance in the Roundhouse Kick to the Head in Taekwondo
2012
Effect of Olympic Weight Category on Performance in the Roundhouse Kick to the Head in Taekwondo In taekwondo, kick performance is generally measured using impact force and time. This study aimed to analyse performance in the roundhouse kick to the head according to execution distance between and within Olympic weight categories. The participants were 36 male athletes divided into three categories: featherweight (n = 10), welterweight (n = 15) and heavyweight (n = 11). Our results show that taekwondo athletes in all weight categories generate a similar relative impact force. However, the results indicate that weight has a large impact on kick performance, particularly in relation to total r…
Coaches’ Corrective Feedback, Psychological Needs, and Subjective Vitality in Mexican Soccer Players
2021
In the sport context, an essential aspect of an athlete’s development and performance happens during the interaction with the coach while receiving information on the aspects of performance that need to be modified (corrective feedback). Grounded in the Self-Determination Theory and particularly on the basic psychological needs theory, a structural equation model (SEM) was tested with the following sequence: perception of the amount of corrective feedback generated by the coach, perceived legitimacy of corrective feedback, satisfaction of basic psychological needs, and vitality in soccer players. Additionally, simple mediation and serial (double) mediation models were also tested. Participa…

Impact force and time analysis influenced by execution distance in a roundhouse kick to the head in taekwondo.
2011
The execution distance is a tactic factor that affects mechanical performance and execution technique in taekwondo. This study analyzes the roundhouse kick to the head by comparing the maximum impact force, execution time, and impact time in 3 distances according to the athletes' competition level. It also analyzes the relationship between impact force and weight in each group. It examines whether the execution distance affects the maximum impact force, execution time, and impact time, in each level group or 2 different competition levels. Participants were 27 male taekwondo players (13 medallists and 14 nonmedallists). The medallists executed the roundhouse kick to the head with greater im…

Effects of target distance on select biomechanical parameters in taekwondo roundhouse kick.
2013
The aim of this study was to investigate the effects of target distance on temporal and impact force parameters that are important performance factors in taekwondo kicks. Forty-nine taekwondo athletes (age = 24.5 +/- 5.9 years; mass = 79.9 +/- 10.8 kg) were recruited: 13 male experts, 21 male novices, 8 female experts, and 6 female novices. Impact force, reaction time, and execution time were computed. Three-way repeated measure ANOVAs revealed significant 'distance' effect on impact force, reaction time, and execution time (p = 0.001). Comparisons between distance conditions revealed that taekwondo athletes kicked with higher impact force from short distance (17.6 +/- 7.5 N/kg) than from l…
