“…It is known that isokinetic dynamometer is a valid and reliable method in predicting muscle strength (Dekerle et al, 2014;Hadzic et al, 2014;Sattler et al, 2015) and it is frequently used in studies (Akarcesme et al, 2017;Markou and Vagenas, 2006;Teixeira et al, 2014). In the literature, there are studies in which isokinetic strength of athletes in different branches of sports and volleyball are measured (Cheung et al, 2012;Kabaciński et al, 2017), studies in which the role of different training programs on isokinetic strength is investigated in volleyball players (Mohammadi et al, 2012;Myer et al, 2006;Pau et al, 2012;Şahin et al, 2015;Yong-Youn and Si-Eun, 2016) and, 'in a remarkable way', many studies conducted on male volleyball players (Bamaç et al, 2008;Çelenk et al, 2019;Cheung et al, 2012;Hadzic et al, 2010;Kim and Jeoung, 2016;Markou and Vagenas, 2006;Özkan and Kin-İşler, 2011;Schons et al, 2018).…”
