The purposes of this study were 1) to investigate the effect of blood lactate disappearance during maximal exercise load and recovery; 2) to deteermine changes of blood lactate concentrations during incremental maximal exercise for the training and non-training groups; 3) to estimate changes of chrdiopulmonary function during exercise and recovery; 4) to analyze changes of plasma epinephrine, and norepinephrine during exercise and recovery.
The subjects of this study consist of a total of 16 young adult women with a mean age of 22.1 year (7 basketball athletes and 9 women students) who are following at Physical Education department in S womens universilty.
Incremental maximal exercise load test and active recovery (Vo2max40%) and passive recovery after Vo2max 100% were conducted on the treadmill three times at a week interval.
1.The results of this study indicated that with increasing time of exercise during the same intensity of exercises oxygen uptake was significanatly「(P<.05) higher in non-training group than training group.
However, oxygen uptake was high in training group(52.34±9.87ml/kg/min) compare to non-training group(46.07±7.01ml/kg/min) at the level of all-out exorcise.
2.Respiratory exchange ratio at 10min absolute maximal exercise load was significantly high(P<.05) in non-training group(0.95 ±0.05) compare to training group(0.90± 0.05).
3.Hear rate at rest, during exercise, and recovery was high in non-training group compare to training group. Especially significant difference(p<.05) could be observde in heart rate between training(148.6±18.3beats/min, 175.0± 12.7beats/min) and non-training groups(164.1 ± 18.3bents/min. 189± 10. 1beats/min) at 6 and 10 min exercise.
4.Ventilation volume increased with increasing title and intensity of exercise and there was no difference between training and non-training groups.
5.Blood lactate concentrations during 6,8, 10, and 12 min of incremental maximal exercise load were significantly (p<.05) low in training group(1.51 ±0.41mM/l, 1.830mM/l. 1.84±0.37mM/l, 3.11 ± 0.33mM/l) compare to non-training group(2.28±0.51mM/l, 3.09±0.50mM/l. 4.85± 1.16mM/l. 6.09 ±0.99mM/1).
6.Blood lacate concentrations at recovery after a brief period of maximal exertcise load was found to be significantly low (p<.01) in trainging group compare to non-training group.
7.Recove rate of blood lactate aftar a brief period of maximal exercise load was significantly high(p<.05) in active recovery method(88.25± 10.85%. 76.30± 14.67%) compare to passive recovery method(42.41 ±8.93%, 46.69± 13.50%).
8.There was no significant change in plasma epinephrine for training 76.27±14.67pg/ml, 60.76±34.53pg/ml and non-training 72.37±23.46pg/ml, 77.10±28.58pg/ml groups at passive and active recovery after a brief period of maximal exercise load. However, plasma epinephring was significantly low(p<.05) in training group compare to non-training group.
9.There was no significant change in plasma norepinephrine for training (232.34±33.16pg/ml, 263.51±93.25pg/ml) and non-training(244.37±91.87pg/ml, 244.97±47.44pg/ml) groups at passive and active recovery after a brief of period of maximal exercise load. However, no significant difference was found in plasma norepinephrine between training antral non-training groups.
10.There were no differences in epinephrine and norepinephrine after a brief period of maximal exercise load for active(271.48±72.16pg/ml, 297.96± 101.21pg/ml) and passive recovery(271.70±81.28pg/ml, 311.69±109.38pg/ml) respectively.
11.No relationships could be observed between epinephrine and norepinephrine concentrations and maximal capillary blood locate values after a brief period of maximal exercise load.
In conclusion, blood lactate concentrations were significantly low in training group after maximal exercise load compare to non-training group. Recovery of blood lactate concentration after exercise was also faster in training group compared to non-training group. Especially, active recovery at rest was found to be more effective blood lactate disappearance. There were no changes in catecholamine after a brief period of maximal exercise load. Catecholamine concentrations were not affected by recovery method and it did not show to be influenced by blood lactate concentrations.
