Cardiovascular studies on former endurance athletes

摘要: Abstract 1. Sixty-one former champion endurance runners or cross-country skiers, 40 to 79 years of age, were submitted a thorough evaluation the cardiovascular system. In addition, study program included series anthropometric measurements and number laboratory tests. A control group 54 nonathletes same age was similar studies. The consisted men in sedentary semisedentary occupations. 2. athletes differed from controls by being shorter, having smaller sitting height body weight, but larger wrist breadth. There no difference ponderal index, knee breadth, biacromial bicristal ratio two latter measures. 3. Both mean systolic diastolic blood pressures ( 137 87 mm. Hg ) significantly lower than those 147 92 ). 4. serum cholesterol level hemoglobin concentration between groups. 5. Coronary heart disease diagnosed 17 15 61 athletes. Eight subjects, only 2 athletes, had symptoms coronary disease. 6. current physical activity greater controls. 7. fewer nonsmokers more heavy smokers, as well exsmokers, 8. Among aged 69, electrocardiogram, Minnesota Code, showed 5 49 1 55 Q QS patterns indicative old myocardial infarction (I1–3); S-T segment depression at rest (IV1–3), after submaximal exercise (XI1–3) 12 8 athletes; flat negative T waves (v1–3, XII1–3) 6 4 High amplitude R (III1) occurred 69. high associated with (6 8) rather hypertension (1 8); association intimate (5 6) loose 6). 9. Twenty-nine 38 considered “healthy” subgroups. subscapular skinfold healthy thinner that controls, whereas there significant upper arm thickness. As regards other measurements, comparison subgroups did not show any essential differences revealed total pressure 10. Healthy maximal QRS vector, roentgenologic volume, rate during exercise, consequently higher calculated oxygen uptake, 11. vector statistically positive correlation volume lack these parameters is suggest dilatation hypertrophy main determinant increased induced training. 12. prevalence electrocardiographic abnormalities compared observed series. “Ischemic” changes occur frequency general population. However, severe manifestations subjective may be rarer among
