05). 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). SCR7 cost 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 was also observed. CONCLUSIONS The present results consist, to the authors' knowledge, in the first description of a protocol to determine the MLSS in dogs. It provides information for exercise monitoring and training planning.BACKGROUND This study examined the association of cardiorespiratory fitness (fitness) and adiposity (body mass index [BMI] and waist circumference [WC]) with ambulatory blood pressure (ABP) and tested the moderating effect of adiposity on the association between fitness and ABP. METHODS A cross-sectional study was conducted with 370 adolescents aged 11-16 years. Fitness was assessed by a height-adjusted step test and estimated by heart rate recovery, defined as the difference between peak heart rate during exercise and heart rate two minutes post- exercise. Adiposity was measured using dichotomized values for percentiles of BMI (≥ 85th) and WC (≥ 50th). ABP was measured every 30-60 minutes over 24 hours on a school day. Mixed- effects regression analysis was used. RESULTS Each unit increase in fitness was associated with a decrease of systolic blood pressure (SBP) [-0.058 mmHg, P = 0.001] and diastolic blood pressure (DBP) [-0.043 mmHg, P less then 0.001] after adjustment for WC and covariates. Each unit increase in fitness was associated with a decrease in SBP [-0.058 mmHg, P = 0.001] and DBP [-0.045 mmHg, P less then 0.001] after adjustment for BMI and covariates. Fitness and BMI ≥ 85th percentile (or WC ≥ 50th percentile) interactions were not associated with ABP after adjustment for covariates. CONCLUSIONS Our findings indicate a small but statistically significant inverse effect of fitness on ABP in adolescents. No evidence of a modifying effect of adiposity on this association suggesting that fitness and weight management have essential roles for maintaining lower ABP in adolescents.BACKGROUND The purpose of this study was to investigate the effect of advising sleep health optimization on anthropomorphic variables following 10 weeks resistance exercise training. METHODS 30 untrained healthy men were recruited for the study and 23 were included in the final analysis. Participants were randomly assigned to exercise and sleep optimization ExS (n=10) or exercise only Ex (n=12). Both groups performed a whole body resistance exercise program twice a week for 10 weeks. The ExS group received sleep health (SH) education on how to improve both sleep quantity and quality. RESULTS After 10 weeks of training both groups had increased lean body mass by a similar amount. The ExS group experienced an increase of 1.7kg ± 1.1kg while the Ex group experienced an increase of 1.3kg ± 0.8kg (p=0.29 for difference between groups). The men in the ExS group reduced fat mass significantly (-1.8kg ± 0.8kg) while the Ex group did not (0.8kg ± 1.0kg). p=0.02 for difference between groups. CONCLUSIONS This randomized controlled trial suggests that combining regular resistance exercise training with optimization of sleep health provide significant added benefits to body composition. This optimization provides a simple and cheap tool, applicable to the general healthy population.OBJECTIVE The objectives of this study were to find correlation between the clinical and ultrasound grading in anterior talofibular ligament and calcaneofibular ligament tear, and to determine the sensitivity and specificity of the two stability tests among the athletes. Subsequently, we would like to propose a new grading criteria for an ultrasound examination. METHODS Two blinded assessors examined thirty-five patients with a history of recent lateral ankle sprain. The first assessor performed physical examination on the injured ankle by using the anterior drawer test and talar tilt test, and the second assessor performed dynamic and static ultrasound assessment for anterior talofibular ligament and calcaneofibular ligament. The clinical laxity grading and sonographic extent of ligamentous injury was graded into a 3-point scale. RESULTS There was a moderate positive correlation between clinical test and ultrasound grading of anterior talofibular ligament and calcaneofibular ligament with Spearman's correlatcould result in a stronger correlation between clinical and ultrasound grading.
