Importance of students’ views and the role of self-esteem in lessons of creative dance in physical education
2016
Abstract The purpose of this study was to capture the student’s views in lessons of creative dance. A qualitative empirical research design was carried out using video-stimulated recall interviews. The participants in this study were 88 children (63 female and 25 male) between the ages of 9 and 11 years (M = 10.5, SD = 1.2) in physical education lessons. A total of 16 teaching units in dance, which took place once a week within a period of 16 weeks were conducted. Of the 88 children, a total of 37 young male and female subjects (M = 10.5 years) were interviewed about their personal views subsequently to the lessons. Transcripts were analyzed using qualitative content analysis. The analysis …
Evaluation of visual-motor reaction time and quality of response in rugby sevens players after the application of a neurocognitive training programme
2019
This work proposes a neurocognitive training (NCT) programme that seeks to optimise the mechanisms of visual perception, the processing of information and decision making. Also, to evaluate the eff...
Vitamin and Mineral Supplementation and Neuromuscular Recovery after a Running Race
2006
International audience; Purpose: This double-blind study investigated the effects of vitamin and mineral complex supplementation on the neuromuscular function of the knee-extensor muscles after a prolonged trail running race. Methods: Twenty-two well-trained endurance runners took either placebo (Pl group) or vitamins and minerals (Vm group) for 21 d before the race and for 2 d after the race. Maximal voluntary contractions (MVC) and surface EMG activity of the vastus lateralis (VL) muscle were recorded before (pre) and 1 h (post), 24 h (post 24) and 48 h (post 48) after the race. Central activation ratio (CAR), neural (M-wave), and contractile (muscular twitch) properties of the quadriceps…
Effets d'une complémentation nutritionnelle en vitamines et minéraux sur la chute de force et les marqueurs biologiques consécutifs à un exercice exc…
2007
Purpose. – The effects of vitamins and minerals complex supplementation on maximal voluntary contraction decrease (FMV) and biological markers following an eccentric exercise at old people. Method. – Sixteen elderly subjects took either placebo (Pl group) or vitamins and minerals (Isoxan Senior, NHS, Rungis, France) (group S) for 21 d before an eccentric exercise and for 3 d after the exercise. The FMV and surface EMG activity (RMS) of the vastus lateralis (VL), vastus medialis (VM) and rectus femoris (RF) were recorded before (Pre), immediately after (Post), 24 h (Post 24) and 48 h (Post 48) after the exercise. CCVThe creatine kinase (CK), lactate deshydrogenase, malondialdehyde, and tumor…
Influence d'une supplémentation en vitamines sur le rendement de la locomotion après une épreuve d'ultratrail
2006
International audience; Aim: The purpose of this study was to study changes in gross efficiency of locomotion after a prolonged trail running race (3000 m up and 300 m down). The second purpose was to investigate the effectiveness of supplementation in vitamin on gross efficiency variability.Materials and methods: Twenty-two well-trained endurance runners took part in this study. They had to perform four sub maximal tests before, 24, 48 and 72 hours after the race in order to estimate gross efficiency of locomotion and a maximal contraction test in the same period. They were divided in two groups either with supplementation (Isoxan Endurance ®) or without (placebo).Results: In both groups w…
Estudio comparativo de cinco revistas de ciencias del deporte indizadas en WoS
2012
La inclusión de las revistas en la Web of Science constituye un importante reconocimiento para sus comunidades científicas, pero los editores deben seguir mejorando su calidad. Por ello se realiza este trabajo de evaluación consistente en la comparación de cinco revistas españolas y brasileñas de ciencias del deporte a partir de 15 indicadores de transparencia, gestión editorial, visibilidad e internacionalización. Los resultados muestran la necesidad de ampliar la información que ofrecen, agilizar los procesos para reducir el tiempo entre recepción y publicación de los artículos y mejorar el factor de impacto. Como estrategias editoriales para incrementar los niveles de excelencia se propo…
Analysis of different key behavioral patterns to score in elite taekwondoists according to the weight category and gender
2021
Traditionally, research in taekwondo has focused on athletes' overall performance considering the entire sample of the tournament or analyzed selected bouts while ignoring behavioral differences of athletes according to their gender and weight category. Thus, the aim of this study was to analyze the behavioral patterns used to score points in the London Olympic Games according to gender and weight category [fin (FW), feather (FTW), light (LW), and heavy (HW)] of the athletes. A total of 24,940 actions were analyzed by using observational methodology, a mixed method methodology where lag sequential and polar coordinate analysis were applied. Different patterns could be seen in the actions pe…
Effects of different circuit training protocols on body mass, fat mass and blood parameters in overweight adults
2017
Benefits of exercise are known for a long time, but mechanisms underlying the exercise mode recommendations for specific chronic cardiovascular diseases remain unclear. The aim of this study was to compare the effects of different circuit training protocols in order to determine which is the best for weight loss and for specific overweight- related disorders. Forty-five female sedentary overweight participants from 20 to 50 years (average 31.8±11.2) were enrolled and assigned to three different groups; each group was compared with a control normal-weight group. Three different circuit protocols were randomly assigned to each overweight group: aerobictone- aerobic (ATA), aerobic-circuit-aero…
Parental and Familial Factors Influencing Physical Activity Levels in Early Adolescence: A Prospective Study
2020
Parental/familial factors are important determinants of the physical activity level (PAL) in children and adolescents, but studies rarely prospectively evaluate their relationships. This study aimed to evaluate the changes in physical activity levels among adolescents from Bosnia and Herzegovina over a two-year period and to determine parental/familial predictors of PAL in early adolescence. A total of 651 participants (50.3% females) were tested at baseline (beginning of high school education
Effects of school-based interventions on motivation towards physical activity in children and adolescents: A systematic review and meta-analysis
2020
Introduction Assuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents. Methods A comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation…
