“…However, the first article regarding fitness self-testing was published about 25 years ago (Knapik et al, 1992). Moving forward, research was nonexistent for 12 years (Corbin, 2004; Mikkelsson et al, 2005; Morgan et al, 2004), then, increased more recently (Graser et al, 2011; Huotari et al, 2009; Rubín et al, 2017). These studies concluded that: (a) HRF self-testing skills were important to students (Corbin, 2004) and could make students feel successful (Morgan et al, 2004); (b) students had positive perceptions of HRF testing, they understood the testing purpose of HRF testing, and made connections between the test results and their personal health (Graser et al, 2011); and (c) the sixth graders in Finland were able to accurately self-test their HRF (Huotari et al, 2009) while Rubín et al (2017) reported that 11–19 year old students in the Czech Republic could estimate their fitness well via self-testing.…”
