로윙에르고미터 최대하 운동 시 활성산소 및 피로물질의 변화에 관한 연구 = The Study on the Changes of Oxygen Free Radical and Blood Fatigue Factors during Submaximal Exercise in Rowing Ergometer

다국어 초록 (Multilingual Abstract)

The purposes of this study were to examine the changes of oxygen free radical and blood fatigue factors during sub maximal exercise using rowing ergometer and to provide the evidences for whole body exercise's effects as well as the rationales. In accomplishing such study purposes, a set of experiments were conducted using one group of 6 rowing players(RP) and the other group of 6 non rowing players(NRP) at the HRR 85~90% exercise intensity. Oxygen free radical was sampled 5 times including a rest period(ARP), immediate after exercise(IAE), 10 minutes after exercise(10MAE), 20 minutes after exercise(20MAE) and 30 minutes after exercise(30MAE). Plus, blood fatigue factors such as lactate, ammonia, lactate dehydrogenase were sampled 4 times including a rest period(ARP), immediate after exercise(IAE), 30 minutes after exercise(30MAE) and 60 minutes after exercise(60MAE). Data collected were analyzed with SPSS 14.0 using two way repeated measures ANOVA, independent t-tests and paired t-tests at the significance level of a=.05. Accordingly, following findings were derived from current study.

1. Oxygen Free Radical

The effects of interaction between groups and times were significant in oxygen free radical(p<.05) and post hoc tests revealed that significant differences occurred between 10MAE and 20MAE and between 20MAE and 30MAE.

2. Blood Fatigue Factors

1) Lactate
The effects of interaction between groups and times were significant in lactate(p<.05) and post hoc tests revealed differences between ARP and IAE and between 30MAE and 60MAE(p<.05).

2) Ammonia(NH3)
The effects of interaction between groups and times were significant in ammonia(NH3) and post hoc tests revealed differences between ARP and IAE, between IAE and 30MAE and between 30MAE and 60MAE(p<.05).

3) Lactate Dehydrogenase(LDH)
The effects of interaction between groups and times were not significant in LDH and thus post hoc tests revealed no difference in time.

To sum up, the effects of rowing ergometer exercise in the RP group were more positive than that in the NRP group and this findings can provide evidences for the effects of whole body exercise and necessity for rowing ergometer exercise.

In conclusion, future research ideas can be suggested as follows. First, further investigation should be done to examine oxygen free radical at more specified time period during recovery, analyze reverse effects of free radical and investigate free radical's recovery effects using more diversified subject groups. Such studies can provide more information on exercise prescription. Second, further study can be conducted to compare the differences in effects of rowing ergometer exercise with exercises, which use upper body or lower body alone, such as treadmill, cycle arm and arm ergometer.
