“…While a large body of literature exists regarding the effects of chronic exercise training on irisin in adults, the results of many studies have been far from conclusive, and no consensus has been reached. Some studies have shown the potential effects of exercise training on circulating irisin (Boström et al, 2012;Ercan et al, 2017;Ghanbari-Niaki et al, 2018;Kim, So, Choi, Kang, & Song, 2015;Moienneia & Hosseini, 2016;Zhao, Su, Qu, & Dong, 2017) and myostatin (Hinkley, Konopka, Suer, & Harber, 2017;Hittel et al, 2010;Roth et al, 2003;Saremi et al, 2010;Walker, Kambadur, Sharma, & Smith, 2004). While others have shown that irisin (Ellefsen et al, 2014;Hecksteden et al, 2013;Moienneia & Hosseini, 2016;Pekkala et al, 2013) and myostatin (Besse-Patin et al, 2014;Binns, Gray, Henson, & Fort, 2017;Hofmann et al, 2016;Ziaaldini et al, 2015) may not change after long-term exercise training.…”
