  • Insights into the personality of 193 German elite youth football players and potential implications for the development of motor performance and injury risk

    Open Access•Sebastian Viktor Waldemar Schulz, Julia Holzapfel et al.•ARTICLE•Frontiers in Sports and Active…•2026•Referências: 1

    To our knowledge, this is the first study applying Cloninger's model in German elite youth football. These findings provide rare descriptive insights into adolescent athletes' personality profiles and suggest that personality may play a greater role in long-term development, resilience, and talent progression than in immediate physical performance

  • Handgrip strength in elite youth football

    Open Access•Sebastian Viktor Waldemar Schulz, Lucas Wizani et al.•ARTICLE•Frontiers in Sports and Active…•2025

    Handgrip strength (HGS) is a simple and reliable indicator of general muscular strength, yet its relevance in elite youth football remains insufficiently understood. This study examined the utility of HGS as a practical indicator of athletic performance in this population, focusing on its associations with sport-specific motor abilities and the moderating influence of age and biological maturation. A total of 221 elite male youth football players…

  • Effects of home confinement on mental health and lifestyle behaviours during the Covid-19 outbreak

    Open Access•Achraf Ammar, Kais Trabelsi et al.•ARTICLE•Biology of Sport•2021

    Although recognised as effective measures to curb the spread of the COVID-19 outbreak, social distancing and self-isolation have been suggested to generate a burden throughout the population. To provide scientific data to help identify risk factors for the psychosocial strain during the COVID-19 outbreak, an international cross-disciplinary online survey was circulated in April 2020. This report outlines the mental, emotional and behavioural cons…

  • Sleep Quality and Physical Activity as Predictors of Mental Wellbeing Variance in Older Adults during Covid-19 Lockdown

    Open Access•Kais Trabelsi, Achraf Ammar et al.•ARTICLE•International Journal of…•2021

    COVID-19 lockdown deleteriously affected physical activity and sleep patterns. Furthermore, change in the total PSQI score and total physical activity energy expenditure were significant predictors for the decrease in mental wellbeing

  • Effects of Covid-19 Home Confinement on Eating Behaviour and Physical Activity

    Open Access•Achraf Ammar, Michael Brach et al.•ARTICLE•Nutrients•2020

    Background: Public health recommendations and governmental measures during the COVID-19 pandemic have resulted in numerous restrictions on daily living including social distancing, isolation and home confinement. While these measures are imperative to abate the spreading of COVID-19, the impact of these restrictions on health behaviours and lifestyles at home is undefined. Therefore, an international online survey was launched in April 2020, in s…

  • Psychological consequences of Covid-19 home confinement

    Open Access•Achraf Ammar, Patrick Mueller et al.•ARTICLE•PLoS ONE•2020

    Background Public health recommendations and government measures during the COVID-19 pandemic have enforced restrictions on daily-living. While these measures are imperative to abate the spreading of COVID-19, the impact of these restrictions on mental health and emotional wellbeing is undefined. Therefore, an international online survey (ECLB-COVID19) was launched on April 6, 2020 in seven languages to elucidate the impact of COVID-19 restrictio…

  • Covid-19 Home Confinement Negatively Impacts Social Participation and Life Satisfaction

    Open Access•Achraf Ammar, Hamdi Chtourou et al.•ARTICLE•International Journal of…•2020

    These preliminary findings elucidate the risk of psychosocial strain during the early COVID-19 home confinement period in 2020. Therefore, in order to mitigate the negative psychosocial effects of home confinement, implementation of national strategies focused on promoting social inclusion through a technology-based solution is strongly suggested
