Triathlon is dev eloping very quickly nowadays. In our paper we are interested in cross triathlon. The road bike is replaced by the mtb mountain bike and the run is also done in the mountain. Triathlon is the endurance kind of sport where the AeT’s (aerobical threshold) a nd AnT’s (anaerobical threshold) level is the basic indicator of a sports performance. The curve of the both thresholds changes under the influence of a lot of factors during the year. We studied the influence of the running preparation on the aerobic and anaerobic threshold at the cross triathlon specialist during one year. We monitored the level, especially the changes in the sports performance during the ATC (annual training cycle). We valued the training proccess, the quantization of the training load and its influence on the triathlet’s performance with the intraindividual analysis.We gained the necessary data from the training diary and with help of the tests realized in the laboratory conditions .We detected the speed at the aerobic and anaerobic thr eshold by the running belt. Then we corelated them with the training parameters and we found out the addaction. We followed their actual influence on the performace and the influence of the training paramaters in the time intervals.

Incremental tests on a treadmill are used to evaluate endurance athletes; however, no criterion exists to determine the intensity at which to start the test, potentially causing the loss of the first lactate threshold. This study aimed to determine the ideal speed for runners to start incremental treadmill tests. The study consisted of 94 runners who self-reported the average speed from their last competitive race (10-42.195 km) and performed an incremental test on a treadmill. The speeds used during the first three test stages were normalised in percentages of average competition speed and blood lactate concentration was analysed at the end of each stage. The relationship between speed in each stage and blood lactate concentration was analysed. In the first stage, at an intensity corresponding to 70% of the reported average race speed, only one volunteer had blood lactate concentration equal to 2 mmol·L-1, and in the third stage (90% of the average race speed) the majority of the volunteers had blood lactate concentration ≥2 mmol·L-1. Our results demonstrated that 70% of the average speed from the subject’s last competitive race - from 10 to 42.195 km - was the best option for obtaining blood lactate concentration <2 mmol·L-1 in the first stage, however, 80% of the average speed in marathons may be a possibility. Evaluators can use 70% of the average speed in competitive races as a strategy to ensure that the aerobic threshold intensity is not achieved during the first stage of incremental treadmill tests.
