- Abstract
Maximal oxygen uptake (Vo2max was evaluated after high-altitude training in rowers. Nine rowers trained in a camp at 1822 m for 3 weeks with no change in Vo2max or 6-min work capacity on a rowing ergometer at sea level. In contrast, 9 control rowers training at sea level increased Vo2max by 4 (0-8)% and work capacity by 3 (0-11)% (median and range). In rowers emphasizing endurance training during a summer of competitive rowing ( n=9), Vo2max and work capacity increased by 6 (0-13)% and 3 (-1-6)%, respectively and no significant changes were noted in rowers performing interval training ( n= 9). Exhaustive rowing on an ergometer was characterized by elevated plasma adrenaline, noradrenaline ( n=13) and lactate ( n=14) (to 19 (11-31), 74 (50-109) nmol l1 and 15 (11-22) mmol-I1, respectively). In heavyweight rowers (n=11), blood volume was 7.0 (5.9-8.3) litres, left ventricular wall thickness 13 (11-15) mm and end-diastolic diameter 57 (54-66) mm ( n=11). This study demonstrated an elevated blood volume in rowers as well as myocardial hypertrophy and large internal heart diameters. In well-trained rowers, endurance training is superior to interval training for elevating Vo2max and work capacity, but high-altitude training does not contribute to increasing Vo2max or work capacity at sea level.
