Abstract EN
Objective.
The aim of this study was to verify the possibility of lactate minimum (LM) determination during a walking test and the validity of such LM protocol on predicting the maximal lactate steady-state (MLSS) intensity.
Design.
Eleven healthy subjects (24.2±4.5 yr; 74.3±7.7 kg; 176.9±4.1 cm) performed LM tests on a treadmill, consisting of walking at 5.5 km⋅h−1 and with 20–22% of inclination until voluntary exhaustion to induce metabolic acidosis.
After 7 minutes of recovery the participants performed an incremental test starting at 7% incline with increments of 2% at each 3 minutes until exhaustion.
A polynomial modeling approach (LMp) and a visual inspection (LMv) were used to identify the LM as the exercise intensity associated to the lowest [bLac] during the test.
Participants also underwent to 2–4 constant intensity tests of 30 minutes to determine the MLSS intensity.
Results.
There were no differences among LMv (12.6±1.7%), LMp (13.1±1.5%), and MLSS (13.6±2.1%) and the Bland and Altman plots evidenced acceptable agreement between them.
Conclusion.
It was possible to identify the LM during walking tests with intensity imposed by treadmill inclination, and it seemed to be valid on identifying the exercise intensity associated to the MLSS.
