Adolescents' postural control learning according to the frequency of knowledge of process
Feedback is one of the most influential factors for motor skills learning. Physical Education teachers commonly use verbal cues to provide knowledge of process (KP) when teaching motor skills, but the ideal presentation frequency for KP in adolescents is unclear. The aim of this study was to compare the effectiveness of the frequency of KP (i.e., 100%, 67%, 0%) on dynamic balance. Thirty adolescents, age 14–15 years, participated in the study. Performance on a stabilometer platform was used to assess dynamic balance. Participants received feedback after each trial (100%), in two out of three trials (67%), or no feedback during 12 30-s trials of practice. Adolescents who received feedback (6…
Judo as a tool for social integration in adolescents at risk of social exclusion: A pilot study
Purpose: Social policies of the advanced countries have begun to incorporate sport to speak on manifestations of social exclusion, as tool to reach out to young people, strengthen their identity or enhance self-esteem vulnerable groups. Judo can be a good tool for the fulfilment of this purpose because has a philosophy and educational practice that contains much of the core competencies of the educational system. The aim of this study is to analyse the incidence of judo practice in changing attitudes, values, norms and capabilities across organizational forms as a means of enhancing socialization in their interventions with young people at risk of social exclusion. Material/Methods: We used…
Efectos del uso de dispositivos de realidad virtual sobre el control postural y el cybersickness en jóvenes universitarios
espanolEl objetivo principal de este estudio fue analizar los efectos de jugar con sistemas de realidad virtual sobre el control postural y el cybersickness. La muestra del estudio estaba compuesta por 21 sujetos de 18 a 30 anos de edad. Todos los sujetos jugaron con un dispositivo de realidad virtual durante 30 minutos. Ademas, todos los sujetos realizaron dos pretest (30 minutos e inmediatamente antes de la prueba) y dos postest (inmediatamente y 30 minutos despues de la prueba). El control postural estatico con ojos abiertos y cerrados y el cybersickness fueron evaluados en todas las pruebas. Los resultados mostraron diferencias significativas entre el pretest 2 y el postest 1 en tres de…
Effects of an incremental maximal endurance exercise stress-induced cortisol on cognitive performance
Exercise; Cognitive functions; Cortisol Ejercicio físico; Funciones cognitivas; Cortisol Exercici físic; Funcions cognitives; Cortisol Objectives: It can be hypothesized that cognitive performance decreases after fatigue protocol when it coincides with the maximum peak of cortisol. The first aim of this study was to elucidate the effects of a single bout of high intensity exercise on behavioural (i.e., attention and memory) and physiological (i.e., salivary cortisol) responses. The second objective was to evaluate the effect of the performance of the cognitive tasks on cortisol levels. Methods: Thirty-four physically active men (at least 5 days/week of physical activity practice) 38.11 (1.5…
Effect of Concurrent Visual Feedback Frequency on Postural Control Learning in Adolescents.
The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequenc…
Dual task cost in balance control and stability in children from 4–7 years old
This study analyzed the development of postural control and the cost of the cognitive task on postural control in the bipedal standing position during childhood. Sixty-six normally developed childr...
Rate of concurrent augmented auditory feedback in postural control learning in adolescents
Introduction: The main objective of this study was to determine the rate of auditory concurrent feedback that best enhanced the learning of a continuous postural task in adolescents. Material and methods: A sample of thirty adolescents (13 to 14-years old) was used, who were assigned to three groups: i) control group (CG); ii) 100% auditory feedback group and iii) 67% auditory feedback group. The subjects performed a pre-test, practice, post-test and a retention (24 hours after the practice). In the postural control task subjects were instructed to remain on a seesaw (unstable in anteroposterior position) and keeping it as level as possible. Results: The results demonstrated that concurrent…

Obesity Affects Postural Control in Middle Childhood and Adolescence but not in Early Childhood
Introduction:Overweight/obese children have postural control differences compared with normal-weight children. Nevertheless, there are not studies that analyze the effect of obesity during the entire period comprised between childhood and adolescence. The objective of this study was to determine the differences in postural control between normal-weight and overweight/obese participants during early and middle childhood and adolescence.Methods:359 children were divided into six groups according to age and weight status. Each participant carried out one 30-s trial with eyes open (EO) and one 30-s trial with eyes closed (EC). Center of pressure signals were acquired using a Wii Balance Board. …
Validation of Using Smartphone Built-In Accelerometers to Estimate the Active Energy Expenditures of Full-Time Manual Wheelchair Users with Spinal Cord Injury
[EN] This study aimed to investigate the validity of using built-in smartphone accelerometers to estimate the active energy expenditures of full-time manual wheelchair users with spinal cord injury (SCI). Twenty participants with complete SCI completed 10 5-min daily activities that involved the upper limbs, during which their oxygen consumption and upper limb activity were registered using a portable gas analyzer and a smartphone (placed on the non-dominant arm), respectively. Time series of 1-min averaged oxygen consumption and 55 accelerometer variables (13 variables for each of the four axes and three additional variables for the correlations between axes) were used to estimate three mu…
Impact of COVID-19 on the self-reported physical activity of people with complete thoracic spinal cord injury full-time manual wheelchair users
The emergence of COVID-19 caused a new public health crisis, leading to major changes in daily life routines, often including physical activity (PA) levels. The main goal of this study was to analyze the differences in self-reported physical activity of people with complete spinal cord injuries between the time prior to the COVID-19 lockdown and the lockdown period itself. A sample of 20 participants with complete thoracic spinal cord injuries completed the Physical Activity Scale for Individuals with Physical Disabilities before and during the COVID-19 lockdown.
