| ABSTRACT |
| 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.
