Abstract
This study aimed at examining physiological responses (i.e., oxygen uptake [VO2] and heart rate [HR]) to a semi-contact 3 × 3-min format, amateur boxing combat simulation in elite level male boxers. Eleven boxers aged 21.4 ± 2.1 years (body height 173.4 ± 3.7, body mass 74.9 ± 8.6 kg, body fat 12.1 ± 1.9, training experience 5.7 ± 1.3 years) volunteered to participate in this study. They performed a maximal graded aerobic test on a motor-driven treadmill to determine maximum oxygen uptake (VO2max), oxygen uptake (VO2AT) and heart rate (HRAT) at the anaerobic threshold, and maximal heart rate (HRmax). Additionally, VO2 and peak HR (HRpeak) were recorded following each boxing round. Results showed no significant differences between VO2max values derived from the treadmill running test and VO2 outcomes of the simulated boxing contest (p > 0.05, d = 0.02 to 0.39). However, HRmax and HRpeak recorded from the treadmill running test and the simulated amateur boxing contest, respectively, displayed significant differences regardless of the boxing round (p < 0.01, d = 1.60 to 3.00). In terms of VO2 outcomes during the simulated contest, no significant between-round differences were observed (p = 0.19, d = 0.17 to 0.73). Irrespective of the boxing round, the recorded VO2 was >90% of the VO2max. Likewise, HRpeak observed across the three boxing rounds were ≥90% of the HRmax. In summary, the simulated 3 × 3-min amateur boxing contest is highly demanding from a physiological standpoint. Thus, coaches are advised to systematically monitor internal training load for instance through rating of perceived exertion to optimize training-related adaptations and to prevent boxers from overreaching and/or overtraining.

Irrespective of the boxing round, paired sample t test showed no significant differences between VO2max values retained from the treadmill running test and VO2 outcomes of the simulated boxing contest (t = −2.00 to 0.06, df = 10, p > 0.05, d = 0.02 to 0.60)

Summary
Amateur boxing is one of the oldest combat sports and it has often been referred to as a “noble art” sport [1]. Amateur boxing is characterized by intermittent bouts of high-intensity activities interspersed with moments of active and passive recovery [3]. During simulated amateur boxing contests, Davis et al [4] demonstrated an activity-to-rest ratio of 9:2. This ratio emphasizes the high physical and physiological demands of amateur boxing. In this regard, a narrative review [1] reported that a well-developed aerobic fitness
