Abstract-This study examined the effect of long term aerobic exercise on cardio-respiratory function, blood pressure and plasma lipid and enzyme profiles : triglyceride(TG), total cholesterol(TG), high and low density lipoprotein(HDL,LDL),
Apoprotein A
and B, glutamic oxaloacetic transaminase(GOT), glutamic pyruvic transaminase(GTP), lactic dehydrogenase(LDH) in old sedentary 10 female subjects(54.5±5.0 yrs).
Subjects were tested a incremental exercise to maximal capacity on a bicycle ergometer to determine VO2max They participated in one year of exercise training with on aerobic exercise for 150minutes per week. The intensity of exercise training was
set to
the level of 50% VO2max
Statistical evaluation of the data was performed using one way ANOVA with repeated measures and Duncan's post hoc tests. Statistical significance was chosen as P<0.1, @ES The findings of the present study were as follows:
@EN 1. VO2max increased slightly after one year of aerobic training exercise.
2. Resting systolic and diastotic blood pressure decreased(P<0.1) and maintained respectively, after training.
3. Plasma TG, TC, HDL, LDL and Apo-B levels were not changed significantly with the exercise training.
4. Plasma Apo-A level was increased significantly(P<0.01) from 128.4±17.6mg/dl to 176.4±36.48mg/dl.
5. Plasma GOT levels was increased significantly from 19.0±3.6 to 30.6±17.7IU/1(P<0.05)
6. GPT and LDH levels decreased significantly(P<0.05) after training
These results suggest that a long term of aerobic exercise is recommenable to improve the cardio-respiratory function and modify of the blood lipid composition in sedentary old subjects.
