The effects of changing daily exercise habit on body fat, serum lipids and symptomlimited maximal exercise test (treadmill by Balke protocol) were evaluated in healthy males and males with mild hypertension (MHT) aged 30 to 59 yr during a period of one year. The subjects were selected from males who underwent physical examination. The results were as follows : A. HEALTHY MALES Study 1 : Subjects who exercised regularly (3 times or more/week) showed higher exercise tolerance and HDL cholesterol (HDLC) and less body fat. Compared to inactive subjects (sports 0〜2 times/week), exercise tolerance was higher in the group who tried to walk as much as possible in their every day life. Study 2 : Inactive subjects without a family history of HT were classified by percentage body fat into three groups (H, M and L). The obese group showed lower exercise tolerance, higher total cholesterol (TC) and lower HDLC. Heart rate (HR) and systolic blood pressure (BPs) at the same load during the exercise test were higher in the obese group. Study 3 : Revisited subjects who did not change their dietary habit for one year were selected from the average group of study 2. The subjects who increased their daily physical activity showed reduced body weight and body fat, increased exercise tolerance and HDLC, and lower HR and BPs under the same work load. B. MALES WITH MILD HYPERTENSION Study 4 : A similar study was conducted in inactive men with MHT (diastolic BP 90〜104 mmHg), non-drug therapy at the first visit and no change in dietary habit for one year. Subjects who increased their daily activity for one year showed reduced body weight and body fat, and both resting BPs and BPd fell by 7 mmHg. HR and BPs decreased under the same work load. These results suggest that an increase in daily physical activity improves physical fitness, reduces blood pressure and decreases body fat in previously healthy males and in males with MHT.
