Behavioural patterns of university students during the COVID-19 pandemic: A cross-sectional study of the effects of active transportation, uninterrupted sitting time, and screen use on physical activity and sitting time.

Background: The closure of universities due to the coronavirus disease 2019 (COVID-19) pandemic may alter the behaviour of students. This study aimed to determine the effect of active transportation duration, uninterrupted sitting time, and screen time to study on physical activity and sitting time during the lockdown.

Relative Age Effects and Self-Organized Sport Practices Among Adults.

Given that previous research on relative age effects (RAEs) has only focused on organized sport, the aim of this exploratory study was to examine whether this phenomenon also existed among self-organized practitioners. In relation to that, a second aim was to know whether self-organized sport practices could be favored by late-born practitioners as a result of a strategic adaptation. Representative sub-samples of 474 soccer players, 363 basketball players, 2,536 swimmers, 1,788 strength training practitioners, 1,873 pétanque players, 973 table tennis players and 2,136 runners were analyzed.

Sports practice in Japan and France: A comparative analysis.

This article aimed to compare the sports participation of populations from two distinct societies with huge cultural differences: France and Japan. At a macro-statistical level and using a societal approach based on two national ad-hoc surveys-in contrast with functionalist and culturalist analyses-it analysed the differences in sports participation between the two populations. The angle adopted for analysing sports participation was that of voraciousness (number and types of sports and physical activities practised).

The team effect on doping in professional male road cycling (2005-2016).

This article questions organizations' (clubs, teams, etc) responsibility in doping use from the case of anti-doping rules violations (ADRVs) sanctioned by the Union Cycliste Internationale in professional cycling. We built a database with 271 caught riders among 10 551 professional riders employed from 2005 to 2016 in the three first world divisions. We developed a time-discrete event history model with a multilevel perspective to consider if the ADRV is related to the characteristic of a rider's career path (level 1) and/or the team by which the rider is employed (level 2).
