Abstract des Autors

Regarding the influence of the left ventricular (LV) adaptation by sports-specific factors the supposed endurance training have so far been compared mainly to strength conditioning. In the present study we investigated the echocardiographic LV measurements of endurance-trained athletes in different kinds of endurance sports (running and ball games) by using matched-pair procedures. We examined 22 male soccer players (S) and 22 male 400-m runners (R) on a regional up to a national level with - each similar in pairs - the following body mass (S: 75.7+/-5.0 kg; R: 75.2+/-5.6), body surface area (S: 1.97+/-0.09 m**2; R: 1.98+/-0.09), fat-free body mass (S: 68.4+/-4.6 kg; R: 68.3+/-5.3) and individual anaerobic threshold as a criterion to determine the running endurance (S: 14.23+/-0.79 km/h; R: 14.25+/-0.80). The body dimensions-related heart volume (HV/lean body mass: S: 14.2+/-1.5 ml/kg; R: 13.4+/-1.0) as well as the absolute and body surface-related LV internal diameter (EDD: S: 55.0+/-3.8 mm; R: 52.7+/-3.3; EDD/body-surface area: S: 27.8+/-1.9 mm/m**2; R: 26.6+/-1.3) were measured significantly higher in S as compared to R. In both groups, free LV wall thickness, enddiastolic diameter and LV muscle mass correlated significantly with the body dimensions (fat-free body mass: r=0.42-0.48-0.56; p<0.004, respectively). In conclusion, specific sport-related strain like frequent exercises in interval form (typical for ball games) and a different volume/intensity ratio could significantly influence the LV adaptation beside the endurance performance as well as constitutional and genetic factors.
