Abstract

The purpose of this study was to develop a suitable test on kayak ergometer to determine the work capacity of kayakers, and to observe the effects of specific training. The test was carried out on 24 kayakers (aged 16 - 29 years). The test lasted 4 min, the resistance force range 4.0-5.5 kp, the rate of paddling was individualy maximal. The total work done, the mean power output as well as the change of power in relation to time were calculated. Oxygen uptake, pulmonary ventilation, and heart rate were measured during the work with the use of Jaeger system. Blood lactic acid concentration, pH and base excess were determined at rest and after work. It was concluded that metabolic response to work on kayak ergometer was similar to 1000 m race. There was high negative correlation (r = 0.794) between the total amount of work done during the test and the time of 1000 m. The seniors were characterized by significantly higher work capacity than juniors. Three months training affected the 15 increase in total work done. Verf.-Referat
