“…To date, studies focused on training load quantification in soccer have largely focused on isolated training drills (Coutts et al, 2009;Casamichana and Castellano, 2010;Buchheit et al, 2015) or mesocyles of up to 10 weeks (Impellizzeri et al, 2004;Gaudino et al, 2013;Scott et al, 2013;Clemente et al, 2019). In contrast, while a plethora of studies have documented the long-term (season long) periodisation models adopted in other football codes (Gabbett and Jenkins, 2011;Moreira et al, 2016;McGahan et al, 2017), little data currently exists in elite soccer. encountered by players competing in the Spanish reserve league (Los Arcos et al, 2017;Martin-Garcia et al, 2018), Dutch Eredivisie League (Stevens et al, 2017), and the English Premier League (Malone et al, 2015;Anderson et al, 2016).…”
