BACKGROUND: Determining the physiological profile of athletes in boxing match is important for defining aspects of physical performance that are important to competitive performance. Therefore, examination of the energy pathway of high-level boxers’ athletes can be very helpful for optimizing training and then improving boxing physical fitness and performance. Objectives: The current study was carried out to assess the physiological and cardiovascular responses during boxing matches and subsequent recovery.
METHODS: Fifteen male international level boxers (age: 19.56±3.6 years; body mass: 72.46±11.86 kg; height: 176.50±7.22 cm) participated in this study. Blood samples were drawn from the antecubital vein before and after the boxing matches (i.e. T1: pre-match rest measure at ~11:00 h, T2: at 3 min of post-match recovery; T3: at 60 min and T4: at 24 h post-match –match started at ~11:30 h). An analysis of glucose, triglycerides, lactate, cholesterol, creatinine, uric-acid, high density lipoprotein, and low density lipoprotein concentrations was performed for each sample. Participants did perform a maximal incremental test to measure HRmax. Heart rate responses to the matches were measured and expressed in percent of HRmax.
RESULTS: The average heart rate recorded during the match corresponded to 93±3.26 % of HRmax. The levels of glucose, lactate, and cholesterol increased significantly from T1 to T2. Likewise, creatinine levels increased significantly from T1 to T2 and T3. However, the cholesterol level decreased significantly at T3 in comparison with T1. Moreover, 24-h post- match, creatinine levels were significantly lower and triglyceride levels were significantly higher compared with T1.
CONCLUSION: The main results of this study revealed that the boxing matches stress the lipid metabolism system during boxing and post-mach (for at least 24h) even if it is widely recognized boxing being mainly composed of repeated short-duration “anaerobic’’ efforts.
