Abstract
The aim of the study was to compare the currently methodics for identification functional and anaerobic thresholds on a bicycle ergometer by triathletes. The sample included triathletes (men), regular participants in the Czech triathlon cup (n = 10, age 35.89 +- 7.94 years, body height 181.83 +- 6.52 cm, weight 80.65 +- 6.53 kg).
In the study, we compared the evaluation methodics using lactate curve, respiratory parameters, theoretical calculation, motor test and Conconi test. For statistical data processing we used the Repeated Measures, for evaluating the significance of differences between each test method then pairwise comparation (Bonferroni test).
Results showed statistically significant differences (p = 0.000). Significantly higher values are reached in Conconi test (173 +- 14.2 beats.min-1, 313 +- 74.8 W).
In pairwise comparison of methodics are differences between lactate and Conconi test in HR values (p = 0.037) as well as the difference between HR lactate test and theoretical calculation (p = 0.039). Most statistical variations in the watts evaluation is found again in connection with Conconi test (time trial: p = 0.039; lactate test: p = 0.013; spiroergometry: p = 0.041).
