Abstract


The study aimed to suggest a specific anaerobic threshold test (AT) to slalom kayak athletes. The AT was determined by progressive kayak exercise (5.0, 6.0, 7.0, 8.0, 9.0 e 9.5km/h) until exhaustion. Two mathematical methods were used: visual inspection and the bi-segmental lactate kinetics (ATi) and by fixed lactate concentration at 4mM (ATobla) and 2.5mM. The ATi and AToblawere compared by ANOVA One-Way and Pearson correlation (p<0.05). The ATi was obtained in 6.98±0.16Km/h, at 2.53±0.25mM and the ATobla 4.0 was 6.95±0.28Km/h, at intensity 11,5% higher than ATi. In this way, it is possible to determine the AT using a specific test to slalom kayak and, if adopted the OBLA, the 2.5mM blood concentration seems to be applicable to slalom kayak athletes.
