“…Seven trials using randomised parallel-group design were included, with a total of 231 participants including children and adults. Three studies included children only (Selvadurai et al, 2002;Klijn et al, 2004;Turchetta et al, 2004), and two notable studies included adults and children (Cerny, 1989;Schneiderman-Walker et al, 2000). Overall, these trials showed some evidence of benefits of short-and long-term physical training for people with CF, and this was also the conclusion provided by other reviews in the field (Smidt et al, 2005;Bradley et al, 2006;Shoemaker and Hurt, 2008).…”
