[Change in the concentration of lipoprotein parameters following swimming training in health resort patients]

Abstract

On 197 patients who were admitted to a sanatorium for the purpose of a heart and circulation cure the influence of a daily swimming training, 20-30 minutes 6 times a week with intensities of about 50-60% VO2 max, on the lipid and lipoprotein spectre, respectively was investigated. In the whole group of patients HDL-cholesterol (HDL-C) did not change. In patients with increased risk n = 40 (initial HDL-C: lower than 0.91 mmol/l) HDL-C significantly increased in the course of the cure. In group I n = 157 (without increase of HDL-C) as well as in group II n = 40 (with increase of HDL-C) LDL-cholesterol significantly decreased. The lipid index after Klimov and the quotient LDL-C/HDL-C decreased at the end of the treatment and they showed the most distinct change in group II. The separation of the lipoproteins by disc electrophoresis and the establishment of their percental distribution resulted in a decrease of the beta-lipoproteins and an increase of the alpha-lipoproteins for the two groups (I and II). The quotient beta-lipoprotein/alpha-lipoprotein also significantly decreased in the two groups. For the apolipoproteins A and B in group II no statistically ascertained changes of concentration were established. At the end of the treatment in group I apolipoprotein B highly significantly decreased, while apolipoprotein A did not change. In accordance with the cholesterol index also the reduction of the apolipoprotein index apo B/A was significant.(ABSTRACT TRUNCATED AT 250 WORDS)
