Sažetak
The purpose of this study is to examine the relationship between the heart rate deflection point (HRDP) and the ventilatory anaerobic threshold (AT) and to determine whether changes in heart rate to workload linearity can be used to accurately estimate AT in elite basketball players. Forty-three professional male basketball players performed a graded maximal exercise test on a motor-driven treadmill. The anaerobic threshold was assessed by a nonlinear increase in carbon dioxide output to oxygen consumption ratio (V-slope method). The HRDP was determined using the method of deflection of linearity by visual inspection There was no statistically significant difference between the. the running speed (RS) at the AT (12.9± ; 1.0 km*h-1) and HRDP (13.0± ; 1.2km*h-1) (p>.05). However, a small but significant difference between the heart rate (HR) at the AT (163.3± ; 7.8 b*min-1) and HRDP (166.3± ; 8.6 b*min-1) was found (p<0.05). We can conclude that the intensity at the HRDP is a potential tool for non-invasive detection of the intensity at the AT based on HR response during graded exercise in professional basketball players.
