“…Ziv and Lidor (2009) stated that 86.20 ± 5.30% of HR peak was achieved during the first half and that 86.70 ± 4.30% of HR peak was achieved during the second half of the warm up match (U18 category). Average heart rate, measuring from 87 to 91% of HR peak, was examined in studies that focused on a cohort of top senior basketball players (Matkovič R.
