The submaximal shuttle-run tests were developed to monitor training responses with heart rate measures as part of a standardized warm-up routine. There are currently two versions of the protocol that have been tailored for use in two specific training groups of basketball and badminton players. ---------- ![ Fig 1 ][1] Example of heart rate (HR) recordings during submaximal shuttle runs as part of preseason performance testing in a semi-professional basketball player.
