Summary
The aim of our study was to compare the effects of different types of short-term endurance training on lipid metabolism in patients with ischaemic heart disease. The study group consisted of 110 male patients (60 after MI and 50 after CABG), aged between 33 and 68. The training was performed on a bicycle ergometer 5 times a week, for 3 weeks. Before and after training program, blood levels of lipids were determined. The models of interval and continuous training were compared. In the next stage, the effect of prolongation of continuous training unit from 30 to 40 minutes was analysed. In patients subjected to continuous training, total cholesterol levels decreased from 213,5 ±12,6 to 199,7 ±10,3 mg/dl (mean ±SEM) (p<0,05) while HDL levels increased from 48,3 ±2,1 to 54,2 ±2,8 mg/dl (p<0.05). In interval training group the significant increase in HDL levels from 38,9 ±1,6 to 43,3 ±2,1 mg/dl (p<0.01) was found only in subjects who initially had low HDL levels. Prolongation of the continuous training unit resulted in beneficial changes in LDL-cholesterol levels from 121,4 ±7,9 to 105,1 ±7,7 mg/dl (p<0,01). Conclusion: 1. The rehabilitation course based on short-term endurance training favourably modifies the cholesterol profile. This effect refers especially to patients with initially worse lipid levels. 2. The continuous training appears to be more effective than interval one with regard to metabolic effects. 3. Prolongation of the training unit causes more favourable modification of lipid profile.
