Effect of 21 days of „living high - training high“ training on sea level swimming performance and haematological blood results in competitive swimmers
Background. The effect of altitude training is a function of both altitude acclimatization and hypoxic exercise The purpose. The purpose of this study was to investigate whether the training and life at an altitude of 2200 meters during three week period improves the speed of swimming at aerobic and anaerobic threshold after returning to sea level. The methods. The sample of subjects consists of 5 well-trained swimmers. The sample of variables consisted tests: aerobic threshold swimming speed before altitude preparation (VAet1), aerobic threshold swimming speed after altitude preparation (VAet2), anaerobic threshold swimming speed before altitude preparation (VAnt1), anaerobic threshold swimming speed after altitude preparation (VAnt2), red blood cell before altitude preparation (RBC1), red blood cell after altitude preparation (RBC2). Results. The results showed that the speed of swimming at Aet increased by 4.1%, and at Ant for 3.3% and number of RBC increased by 3.7% after returning from altitude training. Statistically significant changes between to measurement points were determined in variables: the speed of swimming at aerobic threshold (VAet1, VAet2 ; t= -3.13 ; p=0, 035), the speed of swimming at anaerobic threshold (VAnt1, VAnt2 ; t= -8, 57 ; p=0, 001) Red blood cells (RBC1, RBC2 ; t= -3.34 ; p=0, 029). Discussion and conclusions. Regarding the increase in VAet and VAnt, it can be said that the increase in speed measured during progressive swimming test occurred because of an increase in the number of erythrocytes which is responsible for increased oxygen supply to muscles (increased maximum oxygen consumption), and thus increased the speed of swimming.
