Abstract:
The effects of long-term low intensity aerobic training and detraining on serum lipid and lipoprotein concentrations were examined in 10 older patients suffering from hypertension and coronary heart disease. Training was carried out for 30 minutes 3-6 times a week for a mean of 17.1 months using a treadmill with the intensity level set at the blood lactate threshold (LT) .
Following this training both LT and the serum HDL-c increased significantly (P<0.001, P<0.01, respectively) after 6 months while the TC/HDL-c ratio decreased singificantly (P<0.001) only after 1 month and stabilized at a steady favorable value throughout the remainder of the study. The serum TC, TG and LDL-c did not change significantly by the end of the training period. There was a significant negative correlation between the initial TC/ HDL-c level and the change in the TC/HDL-c level at 1 month after training (r=-0.71, P< 0.02) . Only 1 month after the detraining the HDL-c decreased significantly while the TC/HDL-c increased in comparison with the final training value (P<0.001, P<0.05, respectively) and then returned to the pre-training levels.
In conclusion, these results suggest that long-term low intensity aerobic training could improve the profile of the serum lipid and lipoprotein concentrations in older patients. However, these results might depend on such factors as a low HDL-c level, a high TG level, the length of the exercise period, or the frequency per week and the age of the patient, while the cessation of such training quickly returned the profile to that of pre-training levels.
