　View Summary

In the present study, we instiuted a long-term mild aerobic training program for older patients with hypertension and investigated its effects on serum lipids and lipoprotein concentrations. The intensity of exercise in mild aerobic training was adjusted to the lactate threshold level (LT), i. e., the level at which the blood lactate concentration began to increase nonlinearly with increasing work intensity. The training group (15 patients, 7 men and 8 women) and control group (15 patients, 7 men and 8 women) were 65∼83 year-old patients with mean ages of 75.5±5.6 and 73.7±4.4 (mean±S. D), respectively, who had never exercised regularly up to that time. Treadmill training at the LT was carried out for 30 min/day 3∼6 times/week and continued for 9 months under the supervision of exercise physiology specialists. In the training group, LT speed significantly increased from 3.43±0.65 km/h to 3.73±0.67 km/h (9.0%) in men, and from 2.75±0.57 km/h to 3.05±0.61 km/h (11.8%) in women (both P&lt
0.05). HDL-c was significantly increased 9 months after training both in men (19.2%) and women (20.9%) (both P&lt
.05). The TC/HDL-c ratio, an atherogenetic index, was significantly (P&lt
0.05) decreased by training in women but not in men. The other serum lipid and lipoprotein profiles were unchanged in both men and women. In the control group, all serum lipid and lipoprotein profiles were unchanged in both men and women. The HDL-c level in the training group was higher than in the control group after 9 months in both men and women (both P&lt
0.02). The TC/HDL-c ratio in the training group was lower only in women (P&lt
0.02). There were no significant differences in other values between the training group and the control group in either men or women. These results suggest that mild aerobic training at the LT is an effective method of improving the level of serum HDL-c, the TC/HDL-c ratio and aerobic capacity in the older patients with hypertension. © 1992, The Japanese Society of Physical Fitness and Sports Medicine.
