Abstract

Sieben Marathonläufer (21-42 J.) wurden vor und nach dem Boston-Marathon von 1976 untersucht, um Daten der kardiorespiratorischen und wahrnehmungsbezogenen Erholung nach der Belastung zu gewinnen. Vor und nach dem Rennen durchgeführte Laufbandbelastungen von je 30 min Dauer mit simultaner Erhebung entsprechender Parameter zeigen, dass die subjektiv empfundene Belastungshöhe und die maximale Ventilation die muskuläre Erschöpfung bis 1 Woche nach dem Rennen widerspiegeln. Die kardiorespiratorische Effizienz scheint die Leistungsfähigkeit nach einem Marathonlauf nicht zu begrenzen. -schi-

Abstract

Seven male runners (21-42 years) were examined before and after the 1976 Boston Marathon to provide data concerning the cardiorespiratory and perceptual recovery from the performance. Treadmill runs, 30 min in duration, were administered 1 week prior to the marathon and 2-3, 6-7 and 13-15 days following. Treadmill speed was held constant and based on each runners planed racepace. Maximal performance data were collected 1 week before and 2 weeks after the race. Data were analyzed using a 2-way ANOVA (4 thirty min run data collection periods and 3 exercise time points - 5, 15 and 30 min) and t tests. Treatment effects were not observed for either HR or VE, however, perceived exertion (RPE) was significantly elevated 2-3 and 6-7 days postmarathon and V02 was significantly lower at 13-15 days. HR and RPE showed significant time effects indicating a non-steady state response. None of the maximal test variables were significantly displaced. All variables were returned to pre-marathon levels by 13-15 days except VO2 which was lower. Aerobic capacity was not a limiting factor in the recovery from a marathon run. Musclesoreness and stiffness seem to be related to the increased perceptual ratings following a marathon run. Verf.-Referat
