title: Intra and inter-rater agreement of the Dynamic Movement Assessment ™ Agreement of the DMA™

description: Abstract Aims: To investigate the inter-and intra-rater agreement of the Dynamic Movement Assessment (DMA™) risk classification. Method: In this study, after the anthropometric measurements were made, 17 female soccer athletes were filmed performing the six DMA™ tests (full squat, step-up, single-leg squat, jump test, test plank, and side plank). Both, major and secondary deviations, were observed during the tests. Two experienced health professionals performed video analysis using Kinovea 8.15.0 (inter-rater agreement). To assess the intra-rater agreement, the same video analysis was performed two months later. Participants were rated from 0 to 21 points and at low, medium, moderate, and high risk of developing musculoskeletal injuries. To assess the reliability of the assessment of movement patterns of DMA, the intraclass correlation coefficient (ICC) was performed with a 2-way random-effects model with an absolute agreement (inter-rater) and a 2-way mixed-effects model and consistency (intra-rater). Weighted Kappa Agreement Analysis (kw) was performed with linear weights to assess the level of agreement related to the risk classification of DMA (high, moderate, medium, or minimum). The Analysis was performed with StatsDirect v.3 and SPSS (23.0). Results: Comparing the number of points between the inter-and intra-rater, the ICC was 0.91 (95% CI = 0.74-0.97) and 0.84 (95% CI = 0.59-0.94), respectively, with kw = 0.46 (P = 0.02) intra -rater and kw = 0.46 (P = 0.006) inter-rater (Table 9). Conclusion: DMA has excellent inter-and intra-rater reliability to evaluate movement patterns and classify the risk of musculoskeletal injuries.

title: Biomarker responses of cardiac oxidative stress to high intensity interval training in rats

description: Abstract Aim: The present study aimed to verify the cardiac oxidative stress biomarker responses to high-intensity interval training (HIIT) in rats. Methods: Sixteen male Wistar rats weighing 250 to 300 g were equally divided into two groups (8 animals/group): sedentary control (SC) and trained group (HIIT). The exercise protocol consisted of high-intensity swimming (14% of body weight, 20 s of activity with 10 s of pause performed 14 times) which was performed for 12 consecutive days. Results: The cardiac tissue concentrations of malondialdehyde and carbonylated proteins showed no significant changes; on the other hand, hydroperoxide levels were higher in the HIIT group than in the SC group. The activities of superoxide dismutase, catalase, and glutathione peroxidase enzymes and the levels of reduced glutathione and sulfhydryl remained unchanged. Conclusion: It is possible to conclude that short-term high-intensity interval training induces changes in the cardiac oxidative stress biomarker but with no effect on the antioxidant enzymes.

title: Energy expenditure and intensity of HIIT bodywork® session

description: Abstract Aim: Several programs using total body weight exercise methods have been applied in several populations especially using HIIT. The present study assessed the oxygen consumption, heart rate, and energy expenditure of a HIIT body work® session. Methods: Twelve male participants performed 20 minutes of a HIIT body work, consisting of 20 sets of 30 seconds of stimulation in all-out intensity, followed by 30 seconds of passive recovery. Five cycles were performed for each exercise (jumping jack, burpee, mountain climb, and squat jump). Results: The mean VO2 of the session was 34 ± 7 ml.kg.min-1 (80.35% of the VO2 peak obtained in the session). The energy expenditure of the session was 251±27 kcal (13±1 kcal.min-1) and 39 ± 8 kcal (75±1 kcal.min-1) during the recovery time. The heart rate values were 160±18 bpm (91% of the peak HR of the session) and 125±22 bpm (71%) in recovery. In addition, significant differences (p&lt;0.05) in maximal VO2 were found between jumping jack, mountain climber, burpee and squat jump. Conclusion: Based on the present data, a HIIT bodywork® session presented energy expenditure as a typical high-intensity exercise profile.

title: Psychometric properties of the Brazilian version of the Athlete Burnout Questionnaire (ABQ) in a sample of young and adult athletes

description: Abstract Aims: This study investigated the psychometric properties of the Brazilian version of the Athlete Burnout Questionnaire (ABQ). Methods: Participants were five hundred and nineteen young and adult athletes who responded to the ABQ and Competitive State Anxiety Inventory-2R. Data analysis was conducted through Confirmatory Factor Analysis (CFA), Cronbach’s alpha, Composite reliability, average variance extracted, multigroup analysis, and Pearson’s correlation (p&lt;0.05). Results: The results of the CFA confirmed the structure with three dimensions (Physical and emotional exhaustion (PEE), reduced sense of sports accomplishment (RSSA), and sports devaluation (SD) [χ²/gl=2.92; CFI=.92; TLI=.91; RMSEA=.06]. Internal consistency was satisfactory (&gt;.70). External validity revealed a positive correlation between PEE (r=.14) and RSSA (r=.23) with somatic anxiety and a positive correlation of PEE (r=.15), RSSA (r=.30), and SD (r=.14) with cognitive anxiety. Further, all dimensions of burnout had negative correlations with the self-confidence (r=.17-.23). In the factor invariance analysis, satisfactory data were found in the model’s fit, establishing good factor loadings, variance/covariance, and residuals in both age groups (up to 18 years and over 18 years) and genders (men and women). Conclusion: It was concluded that the Brazilian version of the ABQ is satisfactory for the application of possible studies involving burnout syndrome in the Brazilian sports context in different group extracts.

title: Acute Strength Exercise Decreases Satiety by Modifying Blood Cytokines Levels in Physically Active Men

description: Abstract Aim: Exercise elicits adaptations in several physiological systems, such as the gastrointestinal tract. We evaluated the effects of an acute strength exercise (acute-SE) on gastric satiety and its correlation with creatinine kinase (CK), lactate, and plasma cytokine levels in humans. Methods: Anthropometric parameters, body composition, muscular strength, and satiety (drink test protocol) at rest and exercise were assessed. Results: In the squat, bench press, and T-bar row exercises, we observed a significant decrease (p&lt;0.05) in muscular strength in the second, third, and fourth sets compared with that in the first set. Compared with rest, we observed a significant increase (p&lt;0.05) in CK and lactate levels after acute-SE. In the drink test, acute-SE significantly increased (p &lt;0.05) the total intake, calories ingested, and a total time of ingestion. Concerning cytokines, there was a significant increase (p&lt;0.05) after acute-SE of IL-1β and IL-6 levels at the beginning of the test and a decrease in IL-6, -10, -13, and TNF-α levels after acute-SE at the end of the test (p&lt;0.05). There was a correlation between CK, lactate, and total intake after acute-SE (p&lt;0.05) as well as between IL-6, 13, TNF-α, and volume ingested in the last score of the drink test after acute-SE (p&lt;0.05). Conclusion: Acute-SE decreases satiety associated with changes in lactate, CK, and plasma cytokine levels in healthy humans.

title: Superficial thermal response to CrossFit® workout

description: Abstract Aims: Recently, high-intensity training methods have become popular, integrating the cardiovascular and neuromuscular training in a single training session, among these methods is CrossFit®. The objective of this study was to analyze the superficial thermal response to CrossFit® exercise in men and women, in order to use this knowledge to prevent overuse injuries. Methods: Nineteen volunteers involved in CrossFit® exercise for more than 6-month (12 males and 7 females) were recruited. The acquisition of the thermal images was performed in a climatized room in two moments, at rest (before exercise), and after one CrossFit® training session. The training session lasted 45min, comprising warm-up (10-min), accessory work (15-20min), and workout of the day (15-20-min). Before the first image acquisition, volunteers were acclimated for 15 min. The Wilcoxon signed-rank test was used to compare the skin temperature between pre- and post-exercise. Results: Temperatures rose significantly pre- to post-exercise in the forearm and anterior thigh regions, while it decreased in the anterior thorax and dorsal lower back regions. These results were found both, in the overall sample, and the male volunteers, but not when the female results were isolated. Conclusion: It can be concluded that superficial thermal response to one CrossFit® training session was characterized and was different for men and women. The superficial thermal responses were aligned with the physiological alterations promoted by other modalities, such as resistance training, cycling, and running.

title: What is the effect of vigorous exercise on the brain?

description: Abstract Aims: This study aimed to verify whether vigorous exercise is capable of generating mental fatigue. Methods: To do so, 16 young adult male (29.4 ± 5.2 years old) cyclists (5.4 ± 4.6 years of training) underwent three visits: 1) control session (rest); 2) session with cognitive demand (20 minutes of AX-CPT); 3) session with vigorous exercise (10km time trial). Mental fatigue was assessed using the visual analog scale of fatigue in the pre-and post-session moments. A two-way ANOVA of repeated measures followed by the Bonferroni posthoc was used to verify the effect of the condition (control, cognitive demand, and exercise) and time (pre and post) interaction. The paired “t” test was used to compare the delta of mental fatigue (post - pre) of the sessions. The partial eta squared was used to determine the effect size of the variance. The significance adopted was p &lt; 0.05. Results: A condition x time interaction was observed (F (2.30) = 5.349, p = 0.010, partial η2 = 0.263). When comparing the deltas, a mean difference was found between the control and vigorous exercise (p = 0.033) conditions and cognitive demand and vigorous exercise (p = 0.017) conditions. Control and cognitive demand sessions showed no difference (p = 0.801). Conclusion: The findings suggest that intense physical exercise seems to cause mental fatigue after practice.

title: Physical activity, TV viewing, and human development index in Brazilian adolescents: Results from the National School Health Survey

description: Abstract Aim: This study aimed to examine the association between physical activity (PA) indicators and TV viewing as a function of the Human Development Index (HDI). Method: This cross-sectional study was based on data from the National School Health Survey, which was composed of 102,072 students (14.28±1.03; 51.3% girls). Total PA, active commuting to school (ACS) and TV viewing were assessed by questionnaires and classified through a gradual scale ranging from “F” (low) to “A+” (high). The correlation between total PA, ACS, TV viewing and HDI was verified by Spearman’s Correlation and presented in rs. Results: HDI was positively associated with total PA [girls: rs = 0.572 (p &lt; 0.001); boys: rs = 0.843 (p &lt; 0.001)] and ACS [girls: rs = 0.433 (p &lt; 0.001); boys: rs = 0.554 (p &lt; 0.001)]; while a negative correlation was found between HDI and TV viewing [girls: rs = -0.330 (p &lt; 0.001); boys: rs = -0.348 (p &lt; 0.001)]. Conclusions: Brazilian adolescents from states with higher HDI were more active and spent more time watching TV than their counterparts from states with lower HDI.

title: Do motor performance and specific-skill tests discriminate technical efficiency in small-sided games?

description: Abstract Aim: The aim was to compare performance in specific-skill tests and motor coordination between groups with different technical efficiency and verify possible variables related to specific skills and motor coordination that contribute to discriminate players into high- and low-technical efficiency. Methods: The sample consisted of 82 young soccer players (12-15 years). Body size, bone age, motor performance tests, soccer-specific skill tests, and frequency of technical actions in SSG were analyzed. Statistic cluster-derived ANOVA F was used to identify which variables related to technical action most contributed to classifying subjects with similar performance. Discriminant analysis (Stepwise Method) was used to verify which predictor variables discriminated players into groups of low- and high-frequency technical actions in SSG. Statistical significance was set at 5%. Results: The group of high technical efficiency presented better performance in motor tests, shuttle run (P = 0.04; ES = −0.55), jumping laterally (P = 0.02; ES = 0.58), kicking speed (P = 0.03; ES = 0.60), soccer-specific skill tests, leading the ball in a straight line (LBSL) (P = 0.01; ES = −0.75), and zig-zag ball control (ZZBC) (P = 0.04; ES = −0.55); variable leading the ball in a straight line correctly discriminated 60% of players into high- and low-frequency groups. Conclusion: The frequency of technical actions in SSG was poorly influenced by motor performance and specific skill tests, and only the LBSL test correctly classified players of different frequencies of technical actions in SSG.
