“…This increase in the HDL cholesterol level has also been observed in men after a 70-km ski long-run (11). In recently performed tests on participants of a 20-day marathon over 1100 km, the participants also sh wed an increase in HDL cholesterol levels during the first five days (19). In another study on female participants in a 100km run, increased HDL cholesterol levels were also found after the run (20).…”

“…Although there are studies examining the influence on HDL cholesterol levels of short-term physical activity and physical training (9), there have so far been very few reports on the changes in HDL cholesterol following a single prolonged exercise Session (10 -13). One study showed that male participants in a 100 km run had clearly higher HDL cholesterol values after the run (13). This increase in the HDL cholesterol level has also been observed in men after a 70-km ski long-run (11).…”

“…There are only a few reports on changes of the other HDL components following a severe endurance test. In a recent study of a 20-day run over 1100 km, no changes in apolipoprotein A-I values were observed during the first five days (19). Similarly, in male 100km runners, differences in apolipoprotein A-I were not found when comparing pre-and post-exercise values (13).…”

“…With the exception of 6 participants, the individuals tested consumed moderate amounts of alcohol (beer or wine) Blood samples were taken immediately before and immediately after the run.

“…The majority of the research projects examining this effect, however, tend to treat physical exercise over a short period of time (9). There are relatively few reports on the influence of intensive and long-term exercise, such äs a 100-km run, and these furthermore usually relate to men (10)(11)(12)(13). The influence of long-term, intensive exercise on HDL levels in women is to date largely unknown.…”

Summary: The serum concentrations of total cholesterol and triglycerides äs well äs the cholesterol, phosphatidyl choline, and apolipoprotein components of HDL were tested in 19 participants immediately before and immediately after a 100-mile run.After the run, taking into account any alterations in total protein, the following changes were observed: a decrease in total cholesterol (p < 0.001), äs well äs in triglycerides (p < 0.05), and an increase in HDL cholesterol (p < 0.05), and HDL phosphatidyl choline (p < 0.01). The concentrations of HDL apolipoprotein A-I and HDL apolipoprotein A-II were not affected.The results indicate a change in composition of HDL following extreme prolonged physical exercise in women. Zur Veränderung der HDLrKomponenten bei weiblichen Teilnehmern eines Ultralangstreckenlaufes über 100 MeilenZusammenfassung: Bei 19 weiblichen Teilnehmern eines 100-Meilen Laufes wurden unmittelbar vor und unmittelbar nach dem Lauf die Konzentrationen von Gesamtcholesterin und Triglyceriden sowie der Cholesterin-, Phosphatidylcholin-und Apolipoproteinkpmponenten der HDL im Serum untersucht.Bei Berücksichtigung von Veränderungen des Gesamteiweißes war nach dem Lauf eine Verminderung von Gesamtcholesterin (p < 0,001), und Triglyceriden (p < 0,05) sowie eine Erhöhung der Werte von HDLCholesterin (p < 0,05) und HDL-Phosphatidylcholin (p < 0,01) zu beobachten, während die Konzentrationen von HDL-Apolipoprotein A-I und HDL-Apolipoprotein A-II durch den Lauf nicht beeinflußt wurden.Die Ergebnisse deuten auf eine Änderung in der Komposition der HDL nach extrem ausgedehnter körperlicher Ausdauerbelastung bei Frauen hin.

The influence was examined of ultra-long-distance running (1000 km race lasting 20 days) on changes in serum lipids. The 110 participants received two types of diet, a conventional Western diet and a wholesome vegetarian diet. Of the 55 finishers the serum concentration of total cholesterol, low density lipoprotein (LDL)-cholesterol, apolipoprotein B and triglycerides decreased significantly during the first 8 days of the run, but rose again towards the end of the race without reaching pre-race levels. The high density lipoprotein (HDL)-cholesterol increased initially but decreased in the final days of the run. The values for apolipoprotein A-I were not correlated with HDL-cholesterol. The free fatty acids and free glycerol showed marked increases (five times the prerace concentration), falling towards the end of the run. Changes in serum lipids showed no correlation with changes in body mass. Similar changes were observed in both dietary groups.

Long-distance runners have higher high-density lipoprotein (HDL)-cholesterol concentrations and lower adiposity than sedentary men. Most cross-sectional studies claim that the runners' elevated HDL-cholesterol is not due to the runners' leanness. However, when cross-sectional studies use analysis of covariance (ANCOVA) to adjust for adiposity, or when they compare runners with lean sedentary men, they make an incorrect tacit assumption. They assume that the relationship between change in adiposity and change in HDL-cholesterol in men who have lost fat by running is the same as the cross-sectional difference in HDL-cholesterol between naturally fat and lean sedentary men. Regression slopes for HDL-cholesterol versus adiposity during and at the end of 1 year of running in 35 initially sedentary men suggest this assumption is incorrect; the increase in HDL-cholesterol that accompanies weight loss (−4.28 ± 1.0l mg/l00mL per kg/m 2 ) is considerably greater than the increase in HDL-cholesterol that is associated with lower adiposity cross-sectionally (−0.78±0.46 mg/l00mL per kg/m 2 ). These results suggest the following theory: long-distance runners have the HDL metabolism of men who are below their sedentary set-point weight rather than the HDL metabolism of men who are naturally lean without exercising or dieting. This theory was applied to data from 23 published comparisons between long-distance runners and sedentary men. The differences were highly correlated (r = 0.80) with the theory's predictions (ie, the HDL-cholesterol differences predicted by applying the regression slope for change in HDL-cholesterol vs. change in adiposity to the average differences in adiposity between the runners and sedentary men). These analyses suggest that comparing long-distance runners to a reference population suitably matched for adiposity, and adjusting for adiposity by ANCOVA may each seriously underestimate the contribution of the runners' leanness to their HDL concentrations. These results suggest that the elevated HDL-cholesterol concentrations of long-distance runners are primarily a phenomenon of reduced adiposity.Long-distance runners have higher high-density lipoprotein (HDL)-cholesterol concentrations and lower adiposity than sedentary men [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Most cross-sectional studies claim that the runners' elevated HDL-cholesterol is not due to the runners' leanness. This claim is based on three observations: (1) long-distance runners have significantly higher HDL-cholesterol than sedentary men when adjusted for differences in adiposity by analysis of covariance (ANCOVA) [1,10,14]; (2) long-distance runners have significantly higher HDL-cholesterol than naturally lean sedentary men [18,[20][21][22]; and (3) HDL-cholesterol and adiposity levels are only weakly correlated in cross-sectional samples of runners and sedentary men [6,17,23]. There are experimental data from longitudinal studies that contradict these cross-sectional observations. They suggest that ...
