– Aim: The promulgation of the 1996 Education Guidelines and Bases Law promotes debate on the construction of National Curricular Parameters (NCPs) for Basic Education, emerging traditional disciplines and transversal themes. Considering the relevance of NCPs today, the objective of this research was to analyze NCPs related to health and to identify relationships between health and physical education in NCPs for Physical Education in Elementary and High School. Method: This is a documentary study that analyzed the respective documents. Paul Ricœur's hermeneutic approach was used for the interpretation of these documents. Discussion: In this section, it was identified that these documents recognize health as a right; present a dynamic conception of health and emphasize the importance of citizen education. However, the documents contradict each other by emphasizing a reduction of Physical Education to physical exercise, remodeling of habits, emphasized valorization of biological mechanisms, and contradictory facts to understand health dynamics. Conclusion: Finally, the conclusions emphasize the main points in each document, showing that there are advances but there are also divergences between them related to health issues and even setbacks. In addition, new investigations related to this theme are suggested.

Abstract Aims: This study aimed to analyze the influences of social isolation on the professional performance of Brazilian handball coaches and their expectations for the return of training sessions. Methods: Fifty-two handball coaches participated in this study (Mage=37.4 years; SDage=8.4), who coach U-8 to adult teams, and answered an online survey divided into two main sections: a) coaches' actions with athletes and/or teams throughout social isolation; b) professional learning during social isolation. Descriptive statistics were used for quantitative data analysis and Thematic Analysis for qualitative data analysis. Results: The coaches mentioned that the contact with the teams has been made mostly with WhatsApp (94.2%) and Google Meet or Zoom (75.0%), in which coaches mainly emphasize physical fitness (69.2%) and tactical knowledge (67.3%). For professional learning, coaches are participating in online lectures (96.2%), and virtual meetings (92.3%). Coaches also seek content mainly related to teaching approaches (82.7%), and specific handball exercises (75.0%). Regarding expectations after the social isolation, coaches reported concern about uncertainties for sports practice (restriction of physical contact, decreased incentives for teams, and competitions) and possible psychological benefits (motivation to practice, overcoming difficulties, and learning new resources). Conclusion: The coaches revealed the concern about maintaining the athletes' performance during the social isolation, the uncertainties for the future of the teams, and the difficulties to use different resources for training. We suggested that the courses for coaches emphasize aspects that enable the learning of new technologies (e.g. social networks, video edition, and research platforms).
摘要目的:本研究旨在分析社会隔离对巴西手球教练员职业表现的影响及其对训练回归的期望。方法:52名手球教练参与本研究(年龄37.4岁;SDage=8.4)，他是U-8到成年队的教练，并回答了一项在线调查，该调查分为两个主要部分:a)教练在社会隔离期间与运动员和/或球队的行为;B)社会隔离期间的专业学习。定量数据分析采用描述性统计，定性数据分析采用专题分析。结果:教练提到与球队的联系主要是通过WhatsApp(94.2%)和谷歌Meet or Zoom(75.0%)进行的，其中教练主要强调身体素质(69.2%)和战术知识(67.3%)。对于专业学习，教练参加在线讲座(96.2%)和虚拟会议(92.3%)。教练员还主要寻求与教学方法相关的内容(82.7%)和具体手球练习相关的内容(75.0%)。关于社会隔离后的期望，教练报告了对体育练习的不确定性(身体接触的限制，对团队和比赛的激励减少)和可能的心理益处(练习的动机，克服困难和学习新资源)的担忧。结论:教练员对运动员在社会隔离期间保持竞技状态的担忧，对球队未来的不确定性，以及利用不同资源进行训练的困难。我们建议针对教练的课程强调能够学习新技术的方面(例如社交网络、视频编辑和研究平台)。

– Aim: The aim of this study was to assess the external load of amateur male players during 4 consecutive training microcycles (M) at the beginning of the in-season according to the training session in absolute external load demands and in relation to the competition demands. Methods: Regional-level players (n = 10; age, 20.8 ± 1.7 years; height, 175.5 ± 3.8 cm; body mass, 69.7 ± 2.9 kg; soccer experience, 13.2 ± 2.5 years) were monitored using GPS devices during training sessions and matches. The external load variables measured were: duration (min); total distance covered (TD); distance covered at high-speed (HID, 14.4-19.8 km/h); distance covered at sprinting (SPD; >19.8 km/h); and distance covered in high intensity acceleration (ACD; >2.5 m/s2) and deceleration (DECD; <-2.5 m/s2). Results: The results indicated that the external load variables (time, HID, SPD, ACD, and DECD) were similar between the four microcycles. Greater (p<0.01) time, TD, HID and SPD were observed in match day (MD)-2 compared to MD+1, MD-3, and MD-1. Aside from training duration, all external loads variables (TD, HID, SPD, ACD, and DECD) were lower during training sessions compared to official matches (p<0.05). Conclusion: Amateur soccer players present relative stable external training loads across competitive microcycles, with the peak load observed two days before the official match. Besides this, the match constitutes the highest load during a typical competitive microcycle in this cohort of players.

- Introduction: The relative age effect is prevalent in different elite team sports. However, little is known about this phenomenon in high-level adult male futsal players. Aim: The present study aimed to investigate the prevalence of relative age effect in Brazilian male elite futsal players, and its relationship with playing position and goals scored on Brazil National Futsal Leagues (BNFL) from 2016 to 2020. Methods: The distribution of birth dates, playing positions, and goals scored by male participants of the Brazil National Futsal Leagues were analyzed. Chi-squared tests were used to analyze the birth dates distribution based on quarters and semesters of the year, according to playing position (defender, winger, pivot, and goalkeeper) and scoring performance (high and low). Results: The overall analysis indicated that the relative age effect is prevalent on the pool of athletes analyzed. However, this effect was position-dependent, since relatively older athletes were overrepresented only in wingers and defenders playing positions. On the other hand, scoring performance was not associated with the relative age effect, since this effect was found in both performance levels. Conclusion: Relative age effects are prevalent in Brazilian male elite futsal athletes, especially for defenders and wingers. Considering the high level of competitiveness for spots in elite futsal teams, coaches and sports administrators must be educated about the prevalence of the relative age effect in this sporting context. This is necessary in order to reduce the inequalities generated by age categories based on arbitrary cut-off dates, which may reduce potential talent loss.

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 highintensity 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

–– Aim: The present study aimed to verify if there is a difference between genders in anaerobic capacity estimated by energetic equivalents of glycolytic and phosphagen pathways (AC [La-]+EPOCfast ). Methods: In this way, 8 men and 8 women (physical education students) were subjected to the following sequence of tests: session 1) graded exercise test to measure the maximal oxygen consumption (V ֽ O 2max ) and intensity associated with V ֽ O 2max (iV ֽ O 2max ); sessions 2 to 3) familiarization with supramaximal effort at 115% of iV ֽ O 2max ; session 4) supramaximal effort at 115% of iV ֽ O 2max to measure AC [La-]+EPOCfast . Results: The AC [La-]+EPOCfast was lower in women compared to men when expressed in absolute and relative values (-38.11%; p =0.01 and -25.71%; p =0.03, respectively). A non-significant difference was observed in performance in the supramaximal effort (-12.08%; p =0.15), besides which, a likely negative inference was observed when comparing women to men. In addition, energetic equivalents of the glycolytic pathway (e[La - ]) were also lower in women when expressed in relative and absolute values (-47.01%; p =0.001 and -36.71%; p =0.001, respectively), however no statistical difference was found for energetic equivalents of the phosphagen pathway (ePCr) ( p >0.05).

- aims: This study aimed to investigate the effectiveness of the mat Pilates method, an exercise program, on postural alignment in the sagittal plane among children aged between 8 and 12 years . Method: This study used a blind randomized controlled clinical trial, with a Pilates group (PG) and control group (CG) at the Early Childhood Education Institute. A total of 40 children were randomized, who have no prior knowledge of the Pilates method and no exercise training in the last six months. Mat Pilates exercises were administered twice a week for four months in 50-minute sessions . Postural alignment in the sagittal plane was assessed using photogrammetry . Results: There was no statistically significant difference between the groups post-intervention A significant difference was found in the following outcomes that represent an improvement in intragroup postural alignment: among the children in PG, in the right sagittal view in the vertical body alignment (p=0.019; effect size, ES = 0.70; standardize response mean, SRM = 0.57) and in the sagittal head angle (p=0.035; ES = 0.41; SRM = 0.51). Among the children in the CG, in the vertical alignment of the trunk in the left sagittal view (p= 0.016; ES = 0.50; SRM = 0.44). Conclusion: The effectiveness of Pilates on postural alignment in the sagittal plane among children aged between 8 and 12 years was not confirmed.
