title: Analysis of the Physiological and Metabolic Responses between Two Types of Training in Wistar Rats

description: Abstract This study analyzed the responses of 24 sessions of High Intensity Interval Training (HIIT) and Continuous Moderate (CM) on tissue damage, oxidative stress and glycemic profile of rats in liquid medium. Twenty-four Wistar rats participated, divided into three groups: sedentary (GSED), the one who performed the HIIT (GHIIT) and the one who performed the CM (GCM). Performed three times a week alternately for 8 weeks, and the GHIIT performed 20 seconds of exercise for 10 rest. The CM was a moderate intensity swim. GHIIT increased creatine kinase compared to GSED (GSED: 140.40 + 35.48 U / I; GHIIT: 442.60 + 8.35 U / I; p = 0.0008, representing a percentage increase of 215.24); lactate dehydrogenase was increased in GHIIT and GCM compared to GSED (GSED: 112.8 + 28.08 U / I; GHIIT: 250.9 + 70.67 U / I, a percentage increase of 122.42; GCM: 241.8 + 100.70 U / I, with a percentage increase 114.36; p = 0.006), in contrast, GHIIT increased non-oxidized liver sulfhydryls compared to GCM (GHIIT: 498.70 + 214.30 nmol / ml; GCM: 270.50 + 104.40 nmol / ml, the percentage change was 84.36; p = 0.03). There was greater glycemic maintenance in the GCM (p = 0.0002). It is concluded that the protocols of HIIT and CM, of this study, point to a possible tissue injury, in contrast, HIIT develops the adaptive capacity of the hepatic antioxidant system and the CM promotes greater glycemic support.

title: Efficiency of the goalkeepers in the women’s World Handball Championship in Germany 2017

description: Abstract The performance of goalkeepers can predict the final ranking of teams in tournaments. The aim of the study was to examine the percentages of goalkeepers of different national teams, according to the position on the field from which the pitch was taken, the location of the pitch in the goal and the ranking of the game. To this end, a documentary study based on the data collected by the International Handball Federation was carried out with 24 national teams that took part in the last absolute handball world championship (Germany 2017). The sample consisted of 7606 pitches made in 83 matches. The results showed that the highest percentage of saves was obtained with shots taken from the 9 meters and to the central and middle zone of the goal, and the lowest with throws in fast-breaks and to the lower and lateral areas of the goal. There were no significant differences in the variables analyzed according to the game ranking, except in pitching zone 1.

title: Development and validation of an equation to estimate body fat in elderly women

description: Abstract The purpose of this present study was to develop and validate a prediction equation for body composition assessment using anthropometric measures of elderly women. This is cross-sectional correlational study with 243 older women ± 64.5 years old and body mass index (BMI) ± 28.70 kg/m². For the development of the equation it was utilized the method of hold-out sample validation. The participants were randomly divided into equation development group (96 elderly women) and a group for validation (147 elderly women). Total body mass, height, waist and hip circumferences, ratio waist-hip ratio and BMI were measured. The whole-body dual-energy X-ray absorptiometry (DXA) assessed body composition (percentage of body fat, fat mass, and fat-free mass). The equations were developed using multiple linear regression, with validation by the stepwise method; the comparison of the equations was analyzed by the paired Student's t test and the analysis of residual scores by the method of Blant and Altman. The New Equation presents a strong correlation (R = 0.83) and (R² = 0.69), and a standard error of estimation equals to 3.21% for percentage body fat prediction. The mean difference between the estimations of percentage body fat from DXA and the New Equation was 0.11% (t(0,180); P = 0.850). Therefore, the New Equation had an accuracy of 93.5% and a total error of 1.8%. The body fat estimation in older women using this New Equation based on BMI and age is valid and accurate.

title: Sources of self-efficacy for motor learning in children: systematic literature review in clinical trials

description: Abstract This study aimed to verify the effects of intervention models on the motor activity of children elaborated from the self-efficacy theory. The systematic review of randomized controlled clinical trials with the PRISMA strategy was used. Sixteen studies were descriptively analyzed and revealed that knowledge based on the self-efficacy theory related to motor activity has been more frequently integrated into broad intervention programs in the school environment, collectively applied, stimulating aspects related to children's health and prevention of childhood obesity. Important results were obtained in the development of self-efficacy and motor activity stimulation; however, results are not conclusive regarding the mediation among these variables. Contributions for intervention programs are detailed in this manuscript, allowing the visualization of strategies to build a mastery context, favoring the establishment of an adequate concept of motor self-efficacy in children and the development of self-regulation skills.

title: Post-exercise hypotension in concurrent training: a systematic review

description: Abstract Physical exercise is capable to reduce blood pressure (BP) acutely in a phenomenon described as post-exercise hypotension (PEH). However, the acute effect of concurrent training on PEH needs clarification. The present review aimed to verify and summarize the acute effect of concurrent training on PEH in normotensive and hypertensive subjects. The search was carried out in the databases PubMed, Scielo, and Lilacs, and resulted in 3806 articles. Only 14 studies met the eligibility criteria and were selected. According to included studies, concurrent training can promote PEH regardless of the order, volume, and intensity prescribed, being an effective strategy in the control of arterial hypertension. There is no consensus in the literature regarding the best prescription strategy, as well as the order of execution of the types of exercise.

title: Body segments and biological maturation to estimate the propulsive force of the arm in young swimmers

description: Abstract This study aimed to estimate the propulsive force of the arm (PFA) in young freestyle swimmers and propose an equation to estimate propulsive force, considering anthropometric variables and maturity offset. Seventy-six competitive swimmers [boys: n= 53; age= 13.58 ± 1.79; girls: n= 23; age= 12.98 ± 1.79] participated in this study. Height, lean mass, sitting height, leg length, arm span, triceps skinfold, arm muscle area (AMA), and maturity offset were assessed. The propulsive force of the arm was measured by the tethered swim test. A multiple linear regression (concurrent model) was used to develop the equation using the variables AMA, arm span, and maturity offset. The Bland–Altman method was used to compare the values found between PFA and propulsive force–estimated (PFE). There was a significant correlation between the variables PFA and AMA (R²=0.12; p&lt;0.01), arm span (R²=0.21; p&lt;0.01), and maturity offset (R²=0.20; p&lt;0.01) for boys, whilst in girls theses values were: AMA (R²=0.07;p=0.20), arm span (R²=0.50;p&lt;0.01), and maturity offset (R²=0.44;p&lt;0.01). Two linear equations were established to predict the PFA in boys and girls Bland-Altman analysis showed an agreement between PFA and PFE. In conclusion, the equation is a valuable tool to monitor training and help improve swimmer performance.

title: Aerials and their influence on World Surfing League surfer performance (WSL flights)

description: Abstract This research aimed to verify whether the number of airplanes run by surfers in the 2016 Word Surf League (WSL) men's season and their grades were related to their final classification in the events and season. Were viewed 3475 waves from 49 surfers and selected for analysis 275 waves. Spearman's correlation test, one-way ANOVA, and t-test, with p?0.05, were used for statistical analysis. The air proved to be an effective maneuver in isolated clashes, helped to reach the finals and decide events, but did not prove to be the main determinant of the season's final standings. The average of the marks attributed to the reverse 360 ??aerial was significantly higher than the notes attributed to the reverse aerial, however, the variables the position of the surfer in front or back to wave and whether or not to grab the board edge did not present significant differences.

title: Low level of physical activity and sedentary behaviour in elderly: a systematic review of the parameters

description: Abstract Sedentary behavior tends to increase with aging and several studies have focused on analyzing the components which may influence this pattern of behavior. Indirect and direct measuring have been used to determine the relative parameters to this phenomenon while there is no consensus about which parameter should be adopted to conceptualize sedentary behavior, making difficulty to establish comparisons among the studies on this population. The aim of this study was to systematically review the characterization of low level of physical activity and sedentary behavior in studies with older people. Electronic search on Scielo, LILACS, MEDLINE, PubMed, and ISI Web of Knowledge was carried out. Selection of the studies included: original manuscripts, with elderly analyzing sedentary behavior or low-level pf physical activity through direct and indirect measure. Search initially screened 190 manuscripts yielding 10 relevant studies. Questionnaire, self-reported questionnaire and accelerometer were the instruments used in the studies. Sedentary behavior or low level of physical activity was characterized by analyzing sitting time, physical activity on leisure time, counts per minute, engaging in moderate or vigorous intensity during day or performing physical activities with MET &lt;1.5. There is no standardization of the parameters adopted to characterize sedentary behavior on studies, generating divergent results and making it difficult to establish comparisons.

title: Differences in the physical demands between handball and beach handball players

description: Abstract Handball is one of the most practiced team sports worldwide that consists of different modalities, with the aim of reaching as many users as possible. One of the modalities with increasing interest in the last years is Beach Handball, as it takes the advantage of the absence of competitive calendar in the standardized modality so that users continue practicing. A comparative analysis was performed between standard handball (indoor) and beach handball athletes in order to determine the demands of both modalities and determine if they are similar. The competition was evaluated by analyzing external load variables: number of steps, jumps, impacts and Player load. The selected sample was composed of U-16 players from both modalities. Each player was equipped with WIMUTM inertial device. The results showed that the standard modality requires greater physical demands than the beach modality. For this reason, the physical demands of the different modalities require different training processes to obtain the best possible results in the competition.

title: “Cross” modalities: are the AMRAP, RFT and EMOM models applicable to health?

description: Abstract Currently, training models based on the maximum number of repetitions/rounds or on the execution of a proposed task in the shortest possible time have been gaining ground among Physical Education professionals. However, in our opinion, these models have significant drawbacks that oppose their use in the health context. Thus, we provide an analysis of the problems related to the control and magnitude of the training load (volume and intensity), distribution, duration, and characteristics of the recovery intervals and, of course, the intra-session density. This analysis was made without having measured each of these proposals directly. It is based on the reflection of the dynamics of the efforts made and potential fatigue generated. We hope to be able to verify and provide accurate and reliable data that may support and confirm the hypothesis generated through this analysis.
