  • 摘要:The aim of the study was to ascertain lactate concentration ([LA]) and heart rate (HR) kinetics during standardized interval endurance training on the flat water on the intensity corresponding to the onset of blood lactate accumulation criterion (OBLA). Eight members of the national slalom wild- water kayak team performed two experiments. The first experiment consisted of paddling 8x500 m on flat water through all the gates with the intensity that corresponded to the heart rate determined by OBLA (HROBLA). The second experiment consisted of paddling 8x500m on flat water with the intensity corresponding to the paddling velocity determined by OBLA (vOBLA). The results showed that HROBLA intensity influenced the increase of lactate concentration ([LA]) to 4.4 ± 1.1 mmol/l after the first repetition, however, with a continuous decrease to 3 ± 1.1 mmol/l (P<0.01) after the eighth repetition. When vOBLA was applied, then HR exceeded HROBLA after the second repetition by 8 ± 6 b/min (P<0.05) and further increased until the end. The [LA] reached steady individual values but at very different individual levels which in most subjects exceeded the level of 4 mmol/l (4.8 ± 1.6 mmol/l). In spite of the same phenomena (OBLA), the HROBLA-based endurance training on flat water represents a less intense, and vOBLA-based training a more intense training response.
