“…In a growing body of research, internal training load parameters have been measured using methods such as oxygen consumption (Castagna, Impellizzeri, Chaouachi, Abdelkrim, & Manzi, 2011), blood lactate measurement (Abdelkrim, et al, 2010;Castagna, et al, 2011;Marcelino, et al, 2016), heart rate monitoring Conte, Favero, Niederhausen, Capranica, & Tessitore, 2015, 2016Klusemann, Pyne, Hopkins, & Drinkwater, 2013;Puente, Abian-Vicen, Areces, Lopez, & Del Coso, 2016;Torres-Ronda, et al, 2015) and, the very simple method of rating of perceived exertion (RPE) (Arruda, et al, 2014;Leite, et al, 2012;Manzi, et al, 2010;Nunes, et al, 2014;Scanlan, Wen, Tucker, Borges, & Dalbo, 2014). Foster et al (2001) stated that the use of the session-RPE (sRPE) method might help coaches and athletes achieve their goals while minimizing undesired training outcomes and overtraining.…”
