“…Regarding the type of study, three were randomised-controlled trials (Combs et al, 2013;Jansen et al, 2017;Ciaccioni et al, 2019), one was a non-randomised (pre-experimental) trial (Fleisher et al, 2020), and three had a longitudinal design (Marie-Ludivine et al, 2010;Lantheaume et al, 2017;Dawson et al, 2020). Of these, three studies were developed in the United States of America (Combs et al, 2013;Dawson et al, 2020;Fleisher et al, 2020), one in Canada (Marie-Ludivine et al, 2010), one in Italy (Ciaccioni et al, 2019), one in Germany (Jansen et al, 2017), and one in France (Lantheaume et al, 2017). Regarding the modality of OCS practised, three were interventions with karate (Marie- Ludivine et al, 2010;Jansen et al, 2017;Fleisher et al, 2020), two with boxing (Combs et al, 2013;Dawson et al, 2020), one with judo (Ciaccioni et al, 2019), and one with fencing (Lantheaume et al, 2017).…”
