Psychometric Evaluation of the Norwegian Versions of the Modified Group Environment Questionnaire and the Youth Sport Environment Questionnaire
2021
This study aimed to translate the modified Group Environment Questionnaire (GEQ) and the Youth Sport Environment Questionnaire (YSEQ) into Norwegian, examine the factor structure and reliability of the scales through independent clusters model confirmatory factor analysis (ICM-CFA) and exploratory structural equation modeling (ESEM), and examine differential item functioning (DIF) as a function of sex. Three-hundred-and-thirty-three athletes (M(SD)age = 18.7(2.60) years; 33% females) completed the GEQ. Three-hundred-and-three athletes (M(SD)age = 15.0(1.48) years; 26% females) completed the YSEQ. Results indicated acceptable fit indices for a four-factor, a second-order two-factor (task a…
Assessment of sleep disturbances with the athlete sleep screening questionnaire in Chinese athletes.
2021
This study investigated the factors that are associated with sleep disturbances among Chinese athletes. Sleep quality and associated factors were assessed by the Athlete Sleep Screening Questionnaire (ASSQ, n = 394, aged 18–32 years, 47.6% female). Sleep difficulty score (SDS) and level of sleep problem (none, mild, moderate, or severe) were used to classify participants' sleep quality. Categorical variables were analyzed by Chi-square or fisher's exact tests. An ordinal logistic regression analysis was used to explore factors with poor sleep (SDS ≥8). Approximately 14.2% of participants had moderate to severe sleep problem (SDS ≥8). Fifty-nine percent of the athletes reported sleep distu…
Accelerometer-based physical activity in need satisfaction profiles of schoolchildren: A 3-year follow-up
2023
This study examined moderate-to-vigorous physical activity (MVPA) trends in physical education (PE) classes and beyond school hours in children's need satisfaction profiles over 3 years. Participants were 445 (girls 256, boys 189) Finnish schoolchildren ( Mage = 11.26 ± 0.32 years). Need satisfaction self-reports and accelerometer-based MVPA data were collected in 17 comprehensive schools over four assessment phases. Four latent profiles based on the need satisfaction trends over time were found: Profiles with Large Decrease, Small Decrease, Small Increase, and Large Increase. The children with the most prominent need satisfaction decreases showed a significant decline in out-of-school MVP…
High training volume is associated with increased prevalence of non-allergic asthma in competitive cross-country skiers.
2022
BackgroundCross-country skiers have a high prevalence of asthma, but its phenotypes and association with success in competitions are not known.ObjectiveTo investigate, by means of a postal survey, the relative proportions of allergic and non-allergic asthma in competitive cross-country skiers compared with the general population, to study how performance level and training volume are related to asthma and its type and to assess the possible risk factors for allergic and non-allergic asthma in competitive skiers.MethodsAll Finnish cross-country skiers enrolled in the largest national competitions in winter 2019 (n=1282), and a random sample (n=1754) of the general population of the same age …
Perceived teaching efficacy and coeducational vs. single-sex grouping in physical education teachers
2021
In many countries, sex equality is an essential aim of physical education (PE) curricula, while the PE grouping practices are widely hetero-normative. As far as there is a discrepancy between the curricula and practice, equality will not fully take place. This study examined the associations between PE teachers’ perceived teaching efficacy (student engagement, instruction, class management) and preferences for single-sex (i.e. juridical sex) vs. coeducational grouping in PE. The analysis, based on a cross-sectional online survey of 175 Finnish PE teachers, showed that higher perceived class management was associated with the stronger preferences for single-sex PE. Associations of teacher’s …
Un football des champs et un football des villes : analyse géographique du service football dans un cadre régional
2006
National audience; Le football représente une des formes d'activités de loisir les mieux représentées en France. Au regard de la population concernée par la discipline, il est légitime de la qualifier de service. Cet article propose une lecture géographique de l'offre du service football (les clubs) et de la demande exprimée par les pratiquants. La spatialisation des composants de ce service sportif dans un cadre régional (la Franche-Comté) a pour objectif d'apporter des éléments de connaissance permettant d'ajuster au mieux l'offre des clubs à la demande sociale.
Heteronormativity meets queering in physical education : the views of PE teachers and LGBTIQ+ students
2021
Background and purpose: In school physical education (PE) lessons, gender is often produced heteronormatively. Lesbian, gay, bi, transgender, intersexual, and queer (LGBTIQ+) students have reported experiences of discrimination and obstacles to participation. This study analyzed Finnish PE teachers and LGBTIQ+ students’ talk about discrimination and problematic practices in PE and how equality in PE might be improved. Theoretical background: We draw on the concepts of heteronormativity and habitus. Habitus provides insight on how gendered norms and inequalities become embodied and contested in different social fields. In the PE context, we define social on the one hand as the heteronormativ…
Velocity-based resistance training: do women need greater velocity loss to maximize adaptations?
2021
Abstract Purpose Men and women typically display different neuromuscular characteristics, force–velocity relationships, and differing strength deficit (upper vs. lower body). Thus, it is not clear how previous recommendations for training with velocity-loss resistance training based on data in men will apply to women. This study examined the inter-sex differences in neuromuscular adaptations using 20% and 40% velocity-loss protocols in back squat and bench press exercises. Methods The present study employed an 8-week intervention (2 × week) comparing 20% vs. 40% velocity-loss resistance training in the back squat and bench press exercises in young men and women (~ 26 years). Maximum strengt…
Assessment of Asymmetrical Lower Limb Loading in the Short-Track Speed Skaters
2023
Background. Short-track speed skaters who regularly participate in training are exposed to the occurrence of asymmetry in the lower limb loading. 
 Objective. The study aimed to assess the symmetry of the lower limb loading in short track skaters and the relationship between age, training experience and anthropometric variables and symmetry of lower limb loading.
 Methods. The examined group consisted of 20 short-track speed skaters (12 men and 8 women), and the control group comprised 28 university students (14 men and 14 women). Two scales were used to assess the symmetry of lower limb loading, and the lower limb's loading symmetry index (LSI) was calculated. 
 Results. In …
Advances in Nanoliposomes Production for Ferrous Sulfate Delivery
2020
In this study, a continuous bench scale apparatus based on microfluidic fluid dynamic principles was used in the production of ferrous sulfate-nanoliposomes for pharmaceutical/nutraceutical applications, optimizing their formulation with respect to the products already present on the market. After an evaluation of its fluid dynamic nature, the simil-microfluidic (SMF) apparatus was first used to study the effects of the adopted process parameters on vesicles dimensional features by using ultrasonic energy to enhance liposomes homogenization. Subsequently, iron-nanoliposomes were produced at different weight ratios of ferrous sulfate to the total formulation components (0.06, 0.035, 0.02, an…
