Eighteen trained volunteers (12 men and 6 women: age = 22.0 ± 2.8 years, height = 170.79 ± 7.67 cm, weight = 71.54 ± 12.63 kg) participated in 2-minute, randomized fitness boxing trials, wearing 0.34-kg punching gloves, at various tempos (60, 72, 84, 96, 108, and 120 b·min-1). During each trial, oxygen uptake (Vo2), heart rate (HR), and ventilation (VE) were measured continuously. A rating of perceived exertion (RPE) was attained at the conclusion of each trial. Subjects were able to attain Vo2 values ranging from 26.83 to 29.75 ml·kg-1.min1, which correspond to 67.7–72.5% of Vo2max. The HR responses yielded results ranging from 167.4 to 182.2 b-min-1, or 85 to 93% of HRmax. No significant difference (p > 0.05) was seen with Vo2 between trials, although a significant difference (p < 0.05) was observed with HR, VE, and RPE. It appears that boxing speed is associated with increased VE, HR response, and perceived effort but not with Vo2. Energy expenditure values ranged from 9.8 to 11.2 kcal-min-1 for the boxing trials. These results suggest that fitness boxing programs compare favorably with other exercise modalities in cardiovascular response and caloric expenditure.
