“…In a recent large-scale study (Chekroud et al, 2018), it was found that people who physically exercise, have approximately 43% fewer days/per month of poor mental health than those who do not exercise. Moreover, sufficient research evidence supports the value of several types of leisure-time PA and physical exercise, such as popular team sports (Chekroud et al, 2018), tennis (Groppel & DiNubile, 2009;Yazici, Gul, Yazici, & Gul, 2016), dance (e.g., ballroom dance [Haboush, Floyd, Caron, LaSota, & Alvarez, 2006], Greek traditional dance [Mavrovouniotis, Argyriadou, & Papaioannou, 2010]), aerobic exercise (Broman-Fulks, Berman, Rabian, & Webster, 2004;McAuley et al, 2000), and mindful exercise (Hofmann, Sawyer, Witt, & Oh, 2010) for positive psychological outcomes. It is interesting to note that several researchers report that even one single session of leisure-time PA/ physical exercise, such as aerobic gymnastics (Genti, Goulimaris, & Yfantidou, 2009;Lox & Rudolph, 1994;Netz & Lidor, 2003;Panagopoulou, Charalampopoulos, Piperidou, & Rokka, 2016;Rokka, Mavridis, & Kouli, 2010), Greek traditional dance (GTD) (Genti et al, 2009), or mindful exercise (Netz & Lidor, 2003) can trigger positive psychological responses.…”
