ABSTRACT
This study aims to identify the maximum lactate steady state (MLSS) in obese rats in order to provide a more effective tool in the exercise training prescription for this important animal model. To make such determination, obese (Zucker, n=5) (390.0±18.8 g) and lean (Wistar, n=5) (227.3±26.2 g) rats were studied. After adaptation of animals to treadmill, the MLSS was determined by using 3 different velocities (10 m.min⻹, 12.5 m.min⻹ and 15 m.min⻹ for Zucker and 15 m.min⻹, 20 m.min⻹ and 25 m.min⻹ for Wistar). The MLSS was defined as the highest blood lactate concentration that increased up to 1 mmol.L⻹ during constant exercise. In obese rats, the MLSS was found in a velocity considerably lower than in lean controls (12.5 m.min⻹ and 20 m.min⻹), respectively (p<0.05). Therefore, the identification of MLSS in obese Zucker rats is an important tool for exercise prescription and evaluation in obese rat models.
