The present study was conducted to study the morphological, physiological and biochemical characteristics of Indian National boxers as well as to assess the cardiovascular adaptation to graded exercise and actual boxing round. Two different studies were conducted. In the first study [N = 60, (junior boxers below-19 yrs, n = 30), (senior boxers-20-25 yrs, n = 30)] different morphological, physiological and biochemical parameters were measured. In the second study (N = 21, Light Weight category- <54 kg, n = 7; Medium weight category <64 kg, n = 7 and Medium heavy weight category <75 kg, n = 7) cardiovascular responses were studied during graded exercise protocol and actual boxing bouts. Results showed a significantly higher (p < 0.05) stature, body mass, LBM, body fat and strength of back and grip in senior boxers compared to juniors. Moreover, the senior boxers possessed mesomorphic body conformation where as the juniors' possessed ectomorphic body conformation. Significantly lower (p < 0.05) aerobic capacity and anaerobic power were noted in junior boxers compared to seniors. Further, significantly higher (p < 0.05) maximal heart rates and recovery heart rates were observed in the seniors as compared to the juniors. Significantly higher maximum heart rates were noted during actual boxing compared to graded exercise. Blood lactate concentration was found to increase with the increase of workload during both graded exercise and actual boxing round. The senior boxers showed a significantly elevated (p < 0.05) levels of hemoblobin, blood urea, uric acid and peak lactate as compared to junior boxers. In the senior boxers significantly lower levels of total cholesterol, triglyceride and LDLC were observed as compared to junior boxers. No significant change has been noted in HDLC between the groups. The age and level of training in boxing has significant effect on Aerobic, anaerobic component. The study of physiological responses during graded exercise testing may be helpful to observe the cardiovascular adaptation in boxers. Key PointsStudy on Indian boxersLaboratory testing.Physical, physiological and biochemical monitoring.Performance analysis during actual boxing and laboratory testing.
本研究旨在研究印度国家拳击手的形态、生理和生化特征,以及评估心血管对递增运动和实际拳击回合的适应能力。进行了两项不同的研究。在第一项研究中[N = 60,(19 岁以下的初级拳击手,n = 30),(20-25 岁的高级拳击手,n = 30)],测量了不同的形态、生理和生化参数。在第二项研究中(N = 21,轻量级类别-<54 公斤,n = 7;中量级类别-<64 公斤,n = 7 和中量级类别-<75 公斤,n = 7),研究了心血管在递增运动方案和实际拳击回合中的反应。结果显示,高级拳击手的身高、体重、瘦体重、体脂和背部及握力明显较高(p < 0.05)。此外,高级拳击手具有中胚层体型,而初级拳击手具有外胚层体型。初级拳击手的有氧能力和无氧能力明显较低(p < 0.05)。此外,与初级拳击手相比,高级拳击手的最大心率和恢复心率明显较高。与递增运动相比,实际拳击时的最大心率明显较高。在递增运动和实际拳击回合中,随着工作量的增加,血乳酸浓度升高。与初级拳击手相比,高级拳击手的血红蛋白、血尿素、尿酸和峰值乳酸水平明显升高。与初级拳击手相比,高级拳击手的总胆固醇、甘油三酯和 LDL-C 水平明显较低。两组之间的高密度脂蛋白胆固醇水平没有显著变化。拳击的年龄和训练水平对有氧、无氧成分有显著影响。在递增运动测试期间进行生理反应的研究可能有助于观察拳击手的心血管适应能力。关键点:印度拳击手研究实验室测试身体、生理和生化监测实际拳击和实验室测试期间的表现分析。
