| METABOLIC EFFECT OF PUNCHING TEMPO L. Greene, L. Kravitz, J. Wongsathikun, and T. Kemerly Current fitness industry trends include a growing interest in non-competitive boxing programs. The purpose of this study was to examine the physiological responses of punching at various tempos. Using commercially available boxing equipment, twelve boxing-trained subjects (six male, six female; age = 22.4±3.4, wt = 68.1±13.4 kg) performed straight left and right punches at six different tempos (60, 72, 84, 96, 108, and 120 b/min). Each trial lasted two minutes, similar to that of traditional boxing-round training. Oxygen consumption (VO2), ventilation (VE), and heart rate (HR) were monitored continuously during each round using open circuit spirometry and telemetry. Rating of perceived exertion (RPE) was recorded after each trial. MANOVA with repeated measures revealed a significant (p<0.001) within group effect for trials. Post-hoc comparisons and Friedman test results for RPE are shown below. Results indicate that faster punching tempos increase VO2, VE, and HR response, suggesting a direct relationship between the number of punches thrown per minute and cardiovascular response. |
