Resumo
The present study aimed to describe heart rate (HR) responses during a simulated
Olympic boxing match and examine physiological parameters of boxing athletes. Ten
highly trained Olympic boxing athletes (six men and four women) performed a maximal
graded exercise test on a motorized treadmill to determine maximal oxygen uptake
(52.2 mL ⋅ kg -1 ⋅ min -1 ± 7.2 mL ⋅ kg -1 ⋅ min -1 ) and ventilatory thresholds 1 and 2. Ventilatory
thresholds 1 and 2 were used to classify the intensity of exercise based on respective HR during
.
a boxing match. In addition, oxygen uptake (V O 2 ) was estimated during the match based on
.
the HR response and the HR-V O 2 relationship obtained from a maximal graded exercise test
for each participant. On a separate day, participants performed a boxing match lasting three
rounds, 2 minutes each, with a 1-minute recovery period between each round, during which
.
HR was measured. In this context, HR and V O 2 were above ventilatory threshold 2 during
.
219.8 seconds ± 67.4 seconds. There was an increase in HR and V O 2 as a function of round
(round 3 round 2 round 1, P 0.0001).These findings may direct individual training
programs for boxing practitioners and other athletes.
