Adaptation of the Questionnaire on Teacher Interaction in Tunisia: Teaching Strategies to Promote Sustainable Education in Schools

none7siThe objective of the study was the translation and adaptation into Arabic language of the Questionnaire on Teacher Interaction and the examination of psychometric properties among students in Tunisia. A set of students (N = 778) were recruited to complete a translated, Arabic version of the Teacher Interaction Questionnaire (AQTI). The subjects represented both female and male with an average age of 15.98 ± 2.17 years. The subjects were divided into exploratory (N = 226) and confirmatory (N = 552) samples. For the exploratory sample, the female sex represented 46.90% and the male 53.10% (N = 120). Likewise, the confirmatory sample consisted of females (48.01%) and males (51.99%). The scale designed in Arabic AQTI presented eight components for exploratory factor analysis. The result was a first factorial solution, which kept these eight components of the predetermined instrument. The confirmatory factor analysis provided good fit indices. Similar results for instrument reliability were confirmed for all dimensions, through good Cronbach’s coefficient, which were superior to 0.80. The Arabic version of AQTI is valid and reliable and can be administered to assess teacher/student interactions in Tunisia. However, further research needs to examine the construct validity of the instrument.openSamia Boukari; Noomen Guelmami; Sabri Gaied Chotrane; Sami Bouzid; Aymen Khemiri; Antonella Muscella; Riadh KhalifaBoukari, Samia; Guelmami, Noomen; Gaied Chotrane, Sabri; Bouzid, Sami; Khemiri, Aymen; Muscella, Antonella; Khalifa, Riad

Lower quarter Y balance test: reliability and relation to anthropometric parameters

This study aimed to analyze the Lower Quarter Y Balance Test (Y-BT) reliability in prepubescent male soccer players, as well as the relation between this dynamic balance test performance and some anthropometric parameter

The Effect of Combined Isometric and Plyometric Training versus Contrast Strength Training on Physical Performance in Male Junior Handball Players

Exploring resistance training methods is crucial for optimizing performance programs. Isometric muscle actions have gained popularity in athletic training, but their impact on dynamic performance is uncertain. Isolated isometric actions also lack ecological validity. We compared the effects of 8-week combined isometric and plyometric (COMB) training and contrast strength training (CST) programs on junior male handball players. Thirty-six male first national division players (17.6 ± 1.0 years) were enrolled and randomly assigned to COMB, CST, or control (CONT) groups (all n = 12). Sprinting, change of direction, ball throwing velocity, jumping, and strength were assessed pre- and post-intervention. A significant group × time interaction was observed between the COMB and CONT groups for 20 and 30 m sprints (p ≤ 0.002) and between the COMB and CST groups (p ≤ 0.042). The COMB group had the largest improvements in change of direction and the modified T-test, with significant group × time interactions between the COMB and CONT groups (p ≤ 0.021). Significant group × time interactions were observed between the COMB and CST groups and between the COMB and CONT groups for 3 step running throw (p = 0.003; p p = 0.02; p = 0.031), and jumping throw (p = 0.001; p p = 0.014), with the COMB group outperforming the other groups. Generally, COMB yielded larger improvements than CST. Coaches should consider incorporating a combination of isometric and plyometric exercises for in-season strength training

Profil épidémiologique des épicondylites latérales en milieu de rééducation

Introduction: l´épicondylite latérale, mieux connue sous le nom de « Tennis elbow », fait partie des troubles musculo-squelettiques du membre supérieur et constitue un problème majeur de santé publique. Le but de notre étude est d'évaluer le profil épidémio-clinique et les modalités thérapeutiques des patients suivis au service de médecine physique et réadaptation, pour épicondylite latérale. Méthodes: il s'agit d'une étude rétrospective sur 6 ans (2012-2017) portant sur des patients adressés au Service de Médecine Physique et de Réadaptation Fonctionnelle au CHU Tahar Sfar Mahdia pour une épicondylite latérale. Les caractéristiques sociodémographiques et cliniques ainsi que les modalités thérapeutiques ont été évalués pour chaque patient. Résultats: cinquante patients ont été inclus. L´âge moyen était de 44,82 ans, avec une prédominance féminine (72%). La moitié de nos patients étaient actifs et la majorité (60%) effectuait un travail type bureautique. Le membre supérieur droit était le plus touché dans 78% des cas. La durée moyenne des symptômes était de 14,66 mois. L´examen clinique a révélé une triade tendineuse positive, au niveau des épicondyliens latéraux dans 96% des cas. L´examen radiologique a été réalisé pour 8 patients, et l´échographie pour 6 patients. Tous les patients ont reçu un traitement antalgique, 84% des patients ont reçu des anti-inflammatoires non stéroïdiens et seulement 8 patients ont bénéficié d´une infiltration de corticoïdes. Un seul patient a bénéficié d´un traitement chirurgical après échec de la prise en charge médicale. Des séances de rééducation ont été prescrites chez 92% des patients. Une amélioration totale a été notée chez 42% des patients, 46% ont rapporté une amélioration transitoire et 12% ont évolué vers la chronicité. Conclusion: l´épicondylite latérale est une source fréquente de douleur du coude. Sa prise en charge en Médecine Physique repose sur un traitement médical et une rééducation fonctionnelle adaptée. Mais aucune option thérapeutique ne semble être clairement supérieure à l´autre

An 8-week program of plyometrics and sprints with changes of direction improved anaerobic fitness in young male soccer players

This study examined the effects of 8 weeks of twice-weekly combined plyometric and sprint with change-of-direction (CPSCoD) training into habitual training regimes of young male soccer players. Participants were randomly allocated to an experimental group (n = 17, age: 14.6 ± 0.44 years, body mass: 61.2 ± 7.34 kg, height: 1.67 ± 0.09 m, body fat: 11.2 ± 1.56%) and a control group (n = 16, age: 14.6 ± 0.39 years, body mass: 61.1 ± 3.96 kg, height: 1.67 ± 0.05 m, body fat: 11.8 ± 1.47%). Measures obtained pre- and post intervention included vertical and horizontal jump performance (i.e., squat jump (SJ), countermovement jump (CMJ), and standing long jump (SLJ)), and sprint performance (i.e., 5 m and 20 m sprint). In addition, Measures obtained pre- and post-intervention included change-of-direction ability (4 × 5 m sprint test (S 4 × 5 m) and sprint 9–3–6–3–9 m with backward and forward running (SBF)), repeated change of direction (RCoD), and static balance performance (stork balance test). The training group experienced superior jump (all p < 0.05; d ≥ 0.61), sprint (all p < 0.05; d ≥ 0.58), change-of-direction (CoD) ability (all p < 0.05; d ≥ 0.58), RCoD (all parameters except the fatigue index p < 0.01; effect size (d) ≥ 0.71), and static balance (all p < 0.05; d ≥ 0.66) improvement. Adding twice-weekly CPSCoD training to standard training improves the anaerobic performance of U15 male soccer players

Mental Fatigue Effects on the Produced Perception of Effort and Its Impact on Subsequent Physical Performances

The purpose of this study was to investigate the relationship between mental fatigue induced by a demanding cognitive task and impaired physical performance in endurance due to a higher perception of effort. A total of 12 healthy adults and volunteers, who had previously practiced endurance activities for 4 to 8 h per week, performed a one-hour cognitive task involving either the process of response inhibition (Stroop task) or not (visualization of a documentary as control task), then 20 min of pedaling on a cycle ergometer at a constant perception of effort while cardio-respiratory and neuromuscular functions were measured. The Stroop task induces subjective feelings of mental fatigue (vigor: 3.92 ± 2.61; subjective workload: 58.61 ± 14.57) compared to the control task (vigor: 5.67 ± 3.26; p = 0.04; subjective workload: 32.5 ± 10.1; p = 0.005). This fatigue did not act on the produced perceived effort, self-imposed, and did not affect the cardio-respiratory or neuromuscular functions during the subsequent physical task whose type was medium-term endurance. Regardless of the mental condition, the intensity of physical effort is better controlled when the participants in physical activity control their perception of effort. Mental fatigue does not affect subsequent physical performance but estimated perceived exertion, which increases with the intensity and duration of the exercise
