The association of the step duration in an incremental protocol in the rower ergometer and the maximal lactate steady state intensity
ABSTRACT This study aims to analyse which are better step duration related to the maximum lactate steady-state test (MLSS) intensity and the intensity equivalent to the accumulation of 4mmol/L lactate (AnT4) determined through an incremental protocol using a rowing ergometer, using different steps durations (step3min, step5min, step7min). Ten elite Portuguese rowers (25.1± 4.82 years; 177.5± 5.50 cm; 69.8± 2.74 kg) performed rowing ergometer protocols to determine the maximum lactate steady state (MLSS). Subsequently, incremental tests were realised to determine AnT4, using different step durations (step3min, step5min, step7min). The results showed a strong correlation between MLSS and AnT4 (r> 0.90; p< 0.001) obtained AnT different steps (step3min, step5min, step7min). However, the determined intensity equivalent to 4 mmol/L obtained with different step durations that showed the highest correlation with MLSS (246.5± 35.20W) was verified in the protocol of 7minute steps (251.5± 35,72W). The present study indicates that the use of 7 minutes steps is the most appropriate for determining the AnT4 intensity related to the aerobic component of a high-performance rowing athlete.
