In contrast, the long-term fractal scaling exponent (α2) was greater after exercise compared to baseline and during exercise for all groups (P less then 0.05). MDA significantly decreased after exercise compared to baseline (P less then 0.05). We also found significant correlations after exercise between salivary levels of MDA with HRV components (i.e., RMSSD, SD1, and α2) in asthmatic groups (all P less then 0.05). CONCLUSIONS Our findings showed that exercise in high humidity environment does not significantly differentiate the autonomic response among children with various conditions (i.e., obese, asthmatic and healthy). However, a significant relationship was found between HRV and MDA in asthmatic children after exercise, highlighting the inter-relationship between oxidative stress markers and autonomic function in asthmatic children.BACKGROUND This study aimed to describe a test protocol for the determination of the maximal lactate steady state (MLSS) in dogs. METHODS Ten animals were submitted to a variable number of sessions (3-5), with a duration of 30 minutes each. Every session started with a warm-up period of 10 minutes at 7 km/h, at a 0% inclination. The treadmill was then set at a 5% inclination and at a constant speed, maintained for 20m. In subsequent sessions, speed was increased or decreased 0,5km/h. Blood samples were collected, and blood lactate (BL), heart rate (HR), rectal temperature (RT) and glycaemia were determined at rest (T0), after the warm-up (T1) and every 5 minutes until the end of the test (T2-T5). RESULTS Significant variations were observed in BL, HR and RT, when comparing values at rest and T1 with those at the MLSS level (p less then 0.01). Mean speed at MLSS was 14.6±1.47km/h and BL was 2.7±0.45mmol/L, a value below 4mmol/L. A correlation between BL at MLSS and the visual lactate threshold was observed (0.87). A strong agreement between blood lactate levels at the MLSS level and LTv
