“…Concerning the intervention effects on students' health-related fitness knowledge, 27 (79.4%) of the selected studies had positive intervention effects, and seven studies (20.6%) (Demetriou, Sudeck, & H€ oner, 2014;Gorely, Nevill, Morris, Stensel, & Nevill, 2009;Morris, Gorely, Sedgwick, Nevill, & Nevill, 2013;Mott et al, 1991;Plotnikoff et al, 1999;Ronsley, Lee, Kuzeljevic, & Panagiotopoulos, 2013;Zaremba-Morgan et al, 2014) reported no significant effects. Overall, it is striking that the information provided when presenting the study results is mostly restricted on whether the statistical tests reached significance when analysing students' health-related fitness knowledge levels.…”
