Author's abstract

In order to investigate the comparability of two types of rowing ergometers (Gjessing, GJE, and Concept II, CON) routine exercise tests with a workload increasing step by step (starting with 200 W, increase by 50 W every 3 min with an interruption of 30 sec) were carried out in a random order in 12 rowers. Lactic acid concentration (<lac>), heart rate (HR), and oxygen consumption (VO2) were measured at the end of each workload. Despite identical maximum values for HR, <lac> and VO2 under both conditions the maximum working capacity displayed on the ergometer was significantly different (324 +/- 33,2 W on the GJE and 362,5 +/- 45 W on the CON (p<0,01)). Significant differences were found in submaximum workloads. At 200 and 300 W resp. the values for HR, <lac> and VO2 were higher in GJE compared with CON (p<0,01). As regards the biomechanical and biological examination, further research is needed. Verf.-Referat
