We suggested three-ball sports (handball, soccer, and basketball) share common performance indicators, as rapid intermittent movements primarily characterize each ball sport. Methods: We selected one-hundred and ten, handball (n=30), basketball (n=40), and soccer (n=40) players male and female from local clubs in Hungary. Seventy-nine males and thirty-one females participated in our study; their average age was 14.51 and 14.56, respectively.   They participated in laboratory testing; the protocol included a body composition analysis and spiroergometric tests. We measured body composition and physiological parameters utilizing an In Body 720 device and a standard Bruce treadmill protocol. Although we were aware of the Bruce protocol limitations in elite athletes, we choose this protocol as a safer alternative for younger inexperienced athletes. Results and conclusions: We concluded that in young male soccer and basketball players, mean peak /load (W), peak/VE (l), peak/Vtex (l), peak/ VO 2 (ml/min), peak/VCO 2 (ml/min), and peak/ O 2 pulse (ml) data is a reliable indicator of the sport-specific performance.  We may also suggest that in our male basketball and handball players' population, peak/Vtex (l) is the only variable, which is significantly different. Between groups of male handball and soccer players, peak/VO 2 /kg (ml/min) may be a valid performance indicator. Among female basketball and handball players, we found a significant difference in three performance variables: peak/Vtex (l), peak/VO 2 (ml/min), and peak/ O 2 pulse (ml).application/pdfSport physiology, performance analysis, ball-sports, talent identificationSport physiology, performance analysis, ball-sports, talent identificationfolyóiratcikkOpen AccessJózsef Márton Pucsok, Gergely Ráthonyi, Katalin Varga, Gabriella Perényi, Andrea Lenténé Puskás, Zoltán Bács, László Baloghhttps://doi.org/10.36439/SHJS/2020/2/8595Stadium - Hungarian Journal of Sport Sciences23Stadium2676-9506
