The application of criterion OBLA in prescribing running endurance training intensity is limited = Uporaba kriterija OBLA pri določanju intenzivnosti vzdržljivostne vadbe pri teku je omejenaUšaj, AntonThe criterion "onset of blood lactate accumulation" (OBLA) determined in an incremental testing protocol frequently corresponds to maximal lactate steady state phenomenon (maxLAss) during continuous ... exercise. The aim of this study was to ascertain whether the above-mentioned relationship between both phenomena exists also for intermittent running. Nine healthy runners participated in an incremental testing protocol of repeated 1200 m distances and a training session of 8 x 2000 m, repeated at increased velocities until they were unable to complete the entire session at the required running velocity. Results showed that v[sub]OBLA corresponded to maxLAss during training for seven of the runners, but at increased [ LA] = 5.7 1.2 mmol/l, which is in contrast to LA[sub]OBLA = 4 mmol/l. In contrast, for the two remaining runners, [LA] changed in an non-linear manner. Heart rate (HR) reached steady values of 171[plus minus]8 b/min, similar as HR[sub]OBLA= 170[plus minus] 9 b/min. When the running velocity was increased to v[sub]OBLA+0.2 m/s, a dramatic decrease in running distance occurred because of exhaustion. This phenomenon was accompanied by an increase in [LA] . In contrast to expectations, HR did not increase significantly (175[plus minus]7 b/min). It may be concluded that OBLA may represent a velocity corresponding to maxLAss for most subjects, however it failed to influence blood [LA] response during the test and training sufficiently, to be taken as similar and/or predictable. It seems that HR[sub]OBLA cannot be used as a precise criterion for the determination of HR[sub]maxLAss during training, because it cannot differentiate between v[sub]maxLAss and higher velocity, which effects the early fatigue phenomenon. This means that the OBLA criterion may be a weak method for prescription of running intensity during endurance training.Source: Kinesiologia Slovenica : scientific journal on sport. - ISSN 1318-2269 (Letn. 6, št. 1/2, 2000, str. 57-62)Type of material - article, component partPublish date - 2000Language - englishCOBISS.SI-ID - 920497
