The purpose of this research is to analyze the effects of aerobic exercise on body
composition, cardiopulmonary function, serum lipid level and antioxidants of obese and
normal college female students. The subject group was made up of 13 normal students
(below 30% body fat ratio) and 12 obese students (above 30% body fat ratio). After a
pretest, the subjects were given an 8-week aerobic program. Then the subjects were
given a prosttest and analyzed of body composition, serum lipid level, antioxidants and
cardiopulmonary function after the 6th and the 8th week of the program. The program
schedule was made up of 4 days per week, 60 minutes per day
Test includes B.W., subscapular and triceps subcutaneous fat thickness, change of
respiratory gas, and two blood sampling before treadmill exercise and post all out state,
which analyzed serum lipid and antioxidants. The subjects performed treadmill exercise
starting with 4§°/hr of walking and then gradually increase the speed of 1§°/hr per
minute until all out state.
The obtained data were analysed using SAS program. The statistical methods
employed here were one-way ANOVA with repeated measure, Duncan Multiple range
test, paired -t test and t -test. The test results and conclusion of this research were as
follows.
1. The effects of aerobic exercise on body composition were as follows ; Percent body
fat was significantly reduced 6 weeks after the program and lean body mass was
significantly increased 8 weeks after the program in both groups(obese group F=3.44
P=.044, normal group : F=3.30 P=.048). subscapular skinfold of the obese group showed a
remarkable decrease after the 6th week (F=4.33 P=.021) triceps skinfold of the normal
group showed a remarkable decrease after the 6th and the 8th week (F=4.55 P=.017)
compared with readings before the aerobic program, the aerobic program made a bigger
difference concerning body fat, lean body mass, subscapular skinfold in the obese group
than in the normal group(t=2.41 P=.024, t=2.40 p=.025, 1=2.43 p=.028).
2. The effects of aerobic exercise on cardiopulmonary function were as follows,
Maximal O2 uptake/§¸ was significantly increased 6 weeks after the
program in the obese group(F=3.20 P=.054), but not much difference was observed in
the nor mal group. Maximal pulse rate was significantly reduced in both groups after 6
weeks of the program(obese group : F=2. 77 P=.087, normal group: F=7.17 P=.001).
3. The effects of aerobic exercise on serum lipid level were as follows. In a resting
period, total cholesterol, Triglyceride, and LDL-cholesterol were slightly higher in the
obese group than in the normal group, but HDL-cholesterol was higher in the normal
group. But, with the aerobic program, total-cholesterol, Triglyceride, LDL-cholesterol
were reduced gradually and HDL-choleterol got increased in both groups, but not much
change was noticed in the normal group. However, in the obese group, serum
HDL-cholesterol level got increased significantly(F=5.12 P=.012).
4. The effects of aerobic exorcise in serum antioxidants were as follows ; In a resting
period, the obese group's serum Free Radical and GSSG content were higher than the
normal group's and the normal group's serum GSH content was highier than the obese
group's. After 6 weeks of the aerobic program, Free Radical was reduced significantly
in both groups (obese group : F=13.87 P=.000, normal group: F=18.60 P=.000)
In the obese group, 8 weeks after the program, GSH was increased
significantly(F=13.78, P=.000). In the normal group, 6 weeks after the program GSH was
reduced but increased again after 8 weeks(F=6.07 P=.005).
Plasma GSSG was significantly increased after 8 weeks of exercise in both groups
(obese group: F=19.75 P=.000, normal group: F=22.42 P=.000,). Compared with readings
before the aerobic program, the aerobic program made a bigger difference serum GSH in
the normal group than in the obese group(t=3.37 p=.003).
As this result shows, it is known that the regular aerobic exercise improves
cardiopulmonary function, body composition, serum lipid effectively and through the
serum Free Radical reduction and antioxidant system activation, oxidant stress was
suppressed. This effect was higher in the obese group than in the normal one. At least
6weeks exercise period need for improvement of body composition, cardiopulmonary
function and activation of antioxidant system. This result suggest that improvement of
serum lipid profile was needed longer than 8weeks exercise period.
