Postural Control Profiles of Typically Developing Children From 6 to 12 Years old: An Approach Using Self-Organizing Maps
2020
The purposes of the present study were a) to establish postural control profiles for individuals 6–12 years of age, b) to analyze the participants’ characteristics (age, sex, weight, height, and physical activity) in those profiles, and c) to analyze the influence of visual information in the profiles found. Two hundred and eight typically developing children aged 6–12 years performed two trials in bipedal standing position with eyes open and closed. Feature extraction involved time, frequency, and sway-density plot variables using signals from the center of pressure. A Self-Organizing Map was used to classify and visualize the values of the participants in all the postural control variable…
Competing Effects Between Screen Media Time and Physical Activity in Adolescent Girls: Clustering a Self-Organizing Maps Analysis.
2016
Background:Previous research shows contradictory findings on potential competing effects between sedentary screen media usage (SMU) and physical activity (PA). This study examined these effects on adolescent girls via self-organizing maps analysis focusing on 3 target profiles.Methods:A sample of 1,516 girls aged 12 to 18 years self-reported daily time engagement in PA (moderate and vigorous intensity) and in screen media activities (TV/video/DVD, computer, and videogames), separately and combined.Results:Topological interrelationships from the 13 emerging maps indicated a moderate competing effect between physically active and sedentary SMU patterns. Higher SES and overweight status were l…
Overcoming acculturation: physical education recruits' experiences of an alternative pedagogical approach to games teaching
2015
Background: Physical education teacher education (PETE) programmes have been identified as a critical platform to encourage the exploration of alternative teaching approaches by pre-service teachers. However, the socio-cultural constraint of acculturation or past physical education and sporting experiences results in the maintenance of the status quo of a teacher-driven, reproductive paradigm. Previous studies have reported successfully overcoming the powerful influence of acculturation, resulting in a change in PETE students' custodial teaching beliefs and receptiveness to alternative teaching approaches. However, to date, limited information has been reported about how PETE students' accu…
Sustainable service-learning in Physical Education teacher education: examining postural control to promote ASD children’s well-being
2021
As classrooms become more and more diverse, it is imperative to provide physical education teacher education (PETE) students with opportunities to develop competencies that promote quality education for all students. In this study, PETE students applied a physical education servicelearning (SL) program aimed at enhancing Autism Spectrum Disorder (ASD) children’s motor domain and general well-being—objectives that are connected to the third focus of the United Nations’ Sustainable Development Goals (SDGs). Traditionally, research on SL has focused on students’ outcomes, and there is a call to examine SL’s effects on service receivers, which is the gap this paper aspires to fill. The aim of t…
Percentile values of the standing broad jump in children and adolescents aged 6-18 years old
2020
The standing broad jump (SBJ) is a valid, reliable and feasible field-based test, which can evaluate explosive strength of the lower limbs and physical fitness. This study aimed to provide normative data for the SBJ for male and female children and adolescents and describe differences in performance between age groups and genders. A total number of 2140 children and adolescents, sampled in seven European nations have been included for analysis. The SBJ was performed to derive percentile values for gender and each age group. In general, males have greater jumping performance compared to females. Data demonstrate a linear increase in the jumping distance for both males and females until adole…
Opening up to trans persons in Physical Education–Sport Tertiary Education: two case studies of recognition in queer pedagogy
2018
ABSTRACTBackground: In western societies, commitment to social justice claims for politics of recognition when referring to gender diversity. Gender non-conforming people, such as trans persons, re...
Influence of custom-made and prefabricated insoles before and after an intense run
2017
[EN] Each time the foot contacts the ground during running there is a rapid deceleration that results in a shock wave that is transmitted from the foot to the head. The fatigue of the musculoskeletal system during running may decrease the ability of the body to absorb those shock waves and increase the risk of injury. Insoles are commonly prescribed to prevent injuries, and both custom-made and prefabricated insoles have been observed to reduce shock accelerations during running. However, no study to date has included a direct comparison of their behaviour measured over the same group of athletes, and therefore great controversy still exists regarding their effectiveness in reducing impact …
Oxygen uptake, heart rate and blood lactate levels in female horseback riders during the obstacle test track
2020
The purpose of this study was to examine endurance performance by recording oxygen uptake, heart rate and blood lactate during the obstacle test track, equivalent to competitive performance in female horseback riders. In total 42 female riders participated in the study (show jumping, SJ n = 16, eventing, E n = 26). Age, height and weight of the total group were 29.0(9.2) yrs, 1.68(0.06) m, and 68.1(10.3) kg, respectively. Participants rode a minimum of 4 times per/week, and the riding level was from national to international. VO2peak/VO2mean and HRpeak/HRmean of the total group during the obstacle test track (OTT) were 34.4(5.0)/26.4(4.0) ml/kg/min and 184.4(9.6)/178.1(10.2) bpm. BLa concen…
An initial investigation of smokers’ urges to smoke and their exercise intensity preference: A mixed-methods approach
2016
The purpose of this study was to examine whether smokers preferred a “self-selected” form of physical activity (PA) in which they were allowed to determine themselves the intensity of PA or preferred a “set” form of PA in which the instructor chose the exercise intensity for them. In addition, we examined effects of ‘set” and “self-selected” intensity exercise, on urges to smoke. Participants were 20 (mean age = 27.10 ± 7.37) adults, non-physically active, heavy smokers. Four of them were also interviewed. Results demonstrated that smokers exhibited an enhanced preference for “self-selected” forms of PA as opposed to “set” forms of PA. Smoking urge was significantly lower immediately after…
Racing with superior and inferior team-members: an experimental test of effort changes in a cycling team sprint
2020
The study purpose was to investigate the effect of ability on effort within a sport-specific conjunctive task. The hypothesis was that, compared to working alone, inferior team members would increa...
