장시간 운동과 단식에 의한 체중감량이 혈장량, 혈중 호르몬, 및 혈액 구성 성분 변화에 미치는 효과 = Effect Of Weight Loss Induced By Endurance Exercise and Fasted On Plasma Volume, Blood Hormones, Blood Components

다국어 초록 (Multilingual Abstract)

This study was conducted to elucidate the effect of weight loss induced by endurance exercise and fasted on physiological indexes including the plasma volume, blood hormones, blood components. Total 16 college and high school elite Ssirum players were participated, and randomly divided in to one of two groups; exercise group(n=8), fasting group(n=8). All participants were asked to 3% weight loss by assigned methods. No food (including water) consumption was allowed to all subjects in exercise group, except in fasting group who can drink only limited volume of plain water(300mL ‧ 3 h-1) after 24 hours from the starting time of their fasting, until all subjects reach their established body weight.
Blood samples were taken from antecubital veins at three different time points (i.e., fully rested, immediately after reaching at pre-set target body weight, 24 hr recovery). Factors were analyzed were included following components: body water and stress regulating hormone (i.e., aldosterone and cortisol), hemoglobin (Hb) and hematocrit (Hct), plasma glucose and lactate, blood gas compositions (PCO2, PO2, SO2), and ions (pH, Na+, K+, Ca++, HCO3-). The changes of plasma volume were also calculated by using the level of Hct and Hb.
Means and standard deviations were reported from all data, and 2 × 2 (treatment groups × time points) factorial analyses were performed to elucidate any interactive effects. When no interactions were found, main effects of individual factors were considered, and if any significant effects were found, Tukey's post-hoc test was conducted. To test the change of plasma volume, One-way ANOVA was used to find any mean differences from treatments, and paired t-test was adopted to test of mean differences between two time points.

The main conclusions of this research are the following:

First, the hematocrit level was significantly lower in rest-state compared with p ost-0 in exercise group

Second, the Hb level was significantly lower in recovery-24 compared with post -0 in exercise group

Thrid, there were significant group differences in aldosterone level. At post-o, fa sting group was higher than exercise group in aldosterone level

Fourth, there were both significant difference in pH and Na+ level in rest and re covery-24 compared with post-0 in exercise group.

Fifth, the PCO2 level was significantly higher in recover-24 compared with post -0 in exercise group.

Sixth, there were significant group differences in K+ level. At lest-state, fasting group lower than exercise group in K+ level.

Seventh, there were significant both treatment group and time point differences I n glucose level. At rest-state and post-o, fasting group lower glucose level compared with exercise group. In addition, it was significantly higher at recovery-24 compared with post-0 in fasting group. Those in exercise group, Whereas, that was significantly higher in post-0 compa red with recovery-24.

Eight, there were significant both treatment group and time point differences in lactate level. At recovery-24, fasting group higher lactate level compared with exercise group. In addition, it was significantly higher at rest-state a nd post-o compared with post-24.

Ninth, there was no different in cortisol, PO2, Ca2+, HCO3- level.

Based on these results, this study demonstrated that induced by endurance exercise and fasted, which effects on related to change of physiological indexes (ie., inner body temperature control) and the plasma volume, blood hormones, blood components. Futhermore, in terms of physiological index changes that were more influenced by endurance exercise than fasting treatment.
