The present article aims to analyze child and youth labor in soccer, proposing a normative regulation, due to the possibility of risks to the physical and mental integrity of this population, in light of the Principle of Integral Protection, enshrined by the Constitution of the Federative Republic of Brazil (CRFB/88) and by international treaties, and that recognized to this population segment the condition of subject of rights. As a research methodology, the deductive method was chosen, through eminently bibliographical consultation, and study of the case of the players of Flamengo Regatta Club, victimized in 2019, as a method of procedure. Moreover, as the training of professional athletes in the soccer field is a reality in our country, reaching children and adolescents, and as such, it can be characterized as precocious work, depending on the conditions, the text aims to answer the research problem concerning whether child and youth work in soccer, considering its potential damage to physical and psychological development, is properly regulated in Brazil. The conclusion is that there is insufficient legislation related to the protection of the interests of this group regarding the activities developed in the context of soccer, which ends up denoting a disregard for the peculiar condition of a person in the process of development.

OBJECTIVE: Define the correlation between the rating of perceived exertion (RPE) and the power of the lower limbs before and after training in soccer athletes. METHODS: Were monitored 14 soccer athletes (under 17 years old) over four training sessions. With the following characteristics: height (173±6.81cm), weight (64.43±5.80kg) and fat percentage (14.74±3.11). RPE was monitored through the e-trimp app, 15 minutes after the end of each training session. Jumps were evaluated through the Jump System Pro jumping platform, 10 minutes before and after the training sessions. Data was analyzed in the SPSS statistical program using descriptive statistics and Spearman correlation. RESULTS: The correlation between the RPE and the difference of the relative power of the vertical jump test (pre/post training) was weak for all the sessions. Sessions 1 and 4 presented a negative correlation (r=-0.184, p=0.530; r=-0.159, p=0.587). Sessions 2 and 3 showed a positive correlation (r=0.010, p=0.973; r=0.373, p=0.188), respectively. CONCLUSION: There were no statistically significant correlations between the RPE and the relative jumping power in the evaluated athletes. [ABSTRACT FROM AUTHOR]

OBJECTIVE: This study aimed to compare the performance in the lower limb strength test and flexibility test of athlete of volleyball of the feminine gender, category sub-16, exclusively submitted to the strength training with athletes submitted to the strength training and flexibility training. METHODS: The athletes were divided in two groups. A group carried through the strength training (GTF) and the other group effected the strength training and flexibility training (GTFF). The period of training was of two months. For assessing lower limb strength and flexibility it was opted, respectively, for the horizontal jump test and to sit-and-reach test. It was verified normality of the data through the test of Shapiro-Wilk. Based in these results, Anova two way with post hock of Sidak was used to identify the effect of training in horizontal jump test and sit-and-reach test. For the difference between the initial and final test of each group, the Mann Whitney test was used to identify the difference of the improvement between groups in the strength test and independent test t was used to identify the difference of the improvement between groups of the sit-and-reach test. RESULTS: We found that there was a difference between the different test in the horizontal test [F(2.48)=10.282; p<0.05] and sit-and-reach test [F(2.48)=10.298; p>0,05]. In the horizontal jump test there was a difference in GTF group (p<0.05). In the flexibility test there was a difference in GTFF group. In the comparison between groups, the Mann Whitney test returned value from p=0.924 for the performance of the strength test. Besides that, independent test t returned value from p=0.106 for the performance of the flexibility test. CONCLUSION: We concluded that in view the importance of flexibility for volleyball athletes, it is not possible to refute the use of strength training combined with flexibility training.

In football clubs, favorable relations are expected between the formation of competitive teams, sports performance and financial performance. In Brazil, after Law 13,155/2015, management suffers a series of requirements and those who joined PROFUT add exposure to their finances. In this scenario, the study analyzes the relationships between investment in teams, the financial and sports performance of Brazilian football clubs, pre and post PROFUT membership. For this purpose, it uses data from the clubs that participated in the Serie A of the Brazilian Championship in 2016, the year following the limit for joining PROFUT, submitted to panel data regression. The results reveal favorable relations of investment in training and hiring athletes on sports and financial performance, with effects even after joining PROFUT. However, the expected links between sporting and financial performance have not been identified and alerts are made throughout the survey. The work contributes to discussions about football and finance, discusses moderating effects of joining PROFUT, proposes variables and makes recommendations to clubs. [ABSTRACT FROM AUTHOR]

Brackground: Pre-competitive anxiety is one of the most studied themes among psychological factors for performance in high performance competitions. When it comes to grassroots categories this pressure can be higher considering the psychic structure and age of these little athletes. Objective: The objective of this report is to discuss theoretically the concepts of pre-competitive stress and anxiety, describing an experience of acquiring participants' techniques and behaviors through a training of mental skills on the day of competition. Methods: This study was conducted from the observations of four athletes between 11 and 13 years old at the Brazilian Judo Championship in 2018, after a seven-month period of mental skills training, performed in an intervention project in Sports Psychology. Results: Through reports and observations, it was observed the use of strategies and techniques for anxiety reduction, used by the four athletes participating in the project. Conclusion: The results showed that situational factors such as somatic body sensations and dysfunctional thoughts, denoted the main ways anxiety was experienced by these children. The techniques learned in the mental training experienced by the athletes were applied in competition and had a positive impact on the control of cognitive and somatic anxieties.

With this article, we aim to offer a conceptual synthesis of some of the most important developments in past decades on the subject of talent in sport, while also helping sports stakeholders, particularly managers and coaches, to recognize and apply these conclusions in their practices. The article starts with a brief historical review, which explores how there has been a shift from a talent detection perspective to a talent development perspective and to a holistic vision of athletes and their background context. Secondly, the article presents an overview of the main theoretical models put forward in literature on sport psychology, including career-transition-based models and talent-and-expertise-based models. Finally, as the conceptual model most widely referred to in literature, a detailed analysis of the Development Model of Sports Participation (Côté, Baker & Abemethy, 2007), is made, especially with regard to development processes relating to standards of practice (e.g. diversification and specialization) and psychosocial influences, aspects that form the basis of all-round athlete development.

Introduction: Basketball is a sport that is characterized by the predominance of anaerobic metabolism in providing energy with the importance of power on the different fundamentals, especially in the ability of jump. With intermittent actions in the game, the production of fatigue and decline in athletes' performance is a factor to be investigated. Objective: the objective of the study was to analyze vertical jumps of basketball athletes, playing in different quarters and positions, in two matches. Methods: Study participants were 11 male athletes (age 22.8 ± 3.7 years, body mass 94.15 ± 13.9 kg, height of 196 ± 9.1 cm) in different positions and evaluation of explosive strength of lower limbs was performed with the technique of Counter Movement Jump with the help of arms. he players were evaluated at the beginning of the match and at the end of all quarters. For data analysis we used mean and standard deviation, the Kruskal-Wallis test for normality, Student's T for paired data, comparing the positions. Results: he main results of the jumps indicates to the homogeneity of the initial data for all quarters of the game in both matches and in relation to the playing time and participation, the guards shown significant differences (p <0 , 05) at the jumps evaluated at the second and third quarter, of game 2 and 1, respectively. Conclusion: he results are in accordance with findings of other studies, implying that the lack of fatigue in lower limbs in the act of jumping could be linked to the physiological responses and the number of jumps during the matches.

This exploratory study aimed to analyse the magnitude and duration of the impact generated on the athletes' body during training in Ippon-Seoi-Nage judo technique. Two black belt judo athletes were studied, the tori (the thrower) weighting 75 kg and having 19 years of practice, and the uke (the thrown) weighting 72 kg and having 15 years of practice. A Bruel & Kjaer 4321 Accelerometer Triaxial, fastened to the fist, hip and ankle of the uke, was used. Data were collected in the laboratory. Ten falls were performed for each of the three articulations investigated. The largest impact values were observed for the fist in the vertical axis (351.95 g) and the smallest values were for the hip anterior posterior axis (5.18g). Impact duration times were greater in the hip vertical axis (.58 s) with no differences for the impact on fist and ankle. Considering these high impact values as well as the high frequency of falls during judo training, it is suggested a reevaluation of this training pattern and the sort of tatami adopted, in order to decrease the resulting harmful effects over the time.

The purpose of the present study was to analyze the attacking tasks and tactical organization of elite Women's Water Polo. The sample consisted of 442 attack sequences of 8 games played by the top teams in a European Championship. Seventeen variables were analyzed according to the position and player's participation, tactical organization and playing styles, as well as the efficacy of actions performed. The results from this study indicate that positional attack was the predominant performance factor in the attacking process. To this occurrence, the mixed floating defense was identified as the most frequent opposition. The counter-attack proved to be the most efficient strategy. The attacking process frequently started by ball recovering, in anticipation, and by the defense of the goal-keeper in the 2m zone. In central path, a first long-range pass to the right wing predominated. Teams preferred spontaneous shot on goal supported by assisted displacements, and extra player man offence situations. In general, the attacking sequences, do not take longer than 35s to be developed.) Teams efficiency emerged related to the tactical means adopted, namely the spontaneous shot at goal on the front line and numerical superiority of players in attacking game situations.
