“…The 20-m shuttle run test was preferred in numerous experimental studies and other major field-based test batteries, such as EUROFIT (Council of Europe Committee for the Development of Sport [CECDS], 1988) and ASSO-fitness (Bianco et al, 2015;Tabacchi, 2011) because it has been considered as a valid test for estimating cardiorespiratory fitness (Colombo-Dougovito, 2013;Leger, Mercier, Gadoury, & Lambert, 1988;Mayorga-Vega, Aguilar-Soto, & Viciana, 2015). The handgrip strength and the standing broad jump tests are reliable assessments of musculoskeletal fitness and have been used in scientific studies for more than 50 years (Barfield, Channell, Pugh, Tuck, & Pendel, 2012;Everett & Sills, 1952;Kane & Meredith, 1952;Newman et al, 1984;Wind, Takken, Helders, & Engelbert, 2010). The 4 × 10-m shuttle run test, which demonstrates speed and agility, is a proven positive indicator of bone mass in young people, and many investigations prefer it as a simple and useful field-based fitness test (Ortega et al, 2011;Ortega, Ruiz, Castillo, & Sjöström, 2008).…”
