Abstract Artistic swimming (AS) is a sport evaluated by fifteen judges in routine sessions. The athletes' goal is to achieve proficient motor patterns according to pre-established criteria. The present studied analyzed whether there is difference between the two groups of AS judges with different levels of experience. The group of the International Swimming Federation - FINA (IG) evaluates AS at national and international level and the non-FINA group (NG) evaluates AS only at national level. Twenty experienced judges were divided into groups, 10 IG judges and 10 NG judges. Thus, judges evaluated the item execution of three routines with five required elements. Cronbach's alpha coefficient showed high internal consistency in IG (a= 0.85 in T1 and 0.83 in T2). In NG, internal consistency was observed in T1 and low consistency in T2 (a= 0.82 in T1 and 0.39 in T2). Evaluation analysis between IG and NG was significant (p?0.0330) and reliability analysis (bias: -0.1266 95% agreement limit: -1.642 to 1.388) showed consistency and high degree of confidence in results. The findings suggest that the item execution of required elements showed high objectivity regarding judges with different levels of experience, IG and NG, regardless of categorization and time of practice. FINA has changed the number of judges and the number of items evaluated in routine sessions. It is suggested that the reduction of items has contributed in a positive way so that judges can focus more on evaluation itself.

abstract Basketball is a team sport with short, high intensity movement patterns and rapid and frequent changes of direction. Strength, agility and speed, in addition to specific technical skills, are essential for basketball athletes to achieve good performance. This study aims to verify the effect of a traditional periodization on physical-motor indicators and on specific technical skills in young basketball players. Nineteen young basketball players (15.4 ± 1.3 years), with at least 12 months of training experience, underwent a 5-month periodization. We assessed two physical-motor indicators (countermovement jump (CMJ) and anaerobic capacity (Line Drill)) and two specific technical skills (Dribbling and Shooting) at the PRE and POST training moments. Paired Student's t test was used to test the effect of training on physical-motor variables and technical skills. We calculated the 95% confidence interval of the average relative gain (Δ%) for each variable and analyzed the effect size through Cohen's d (p≤ 0.05). Significant differences were found between the PRE and POST moments in the CMJ (34.02 vs. 38.64 cm; p <0.001), in the Line-Drill (33.20 vs. 31.73 s; p <0.001), Dribbling (6.95 vs. 6.66 s; p <0.001), and Shooting (15.84 vs. 17.95 pts; p <0.001). Young school-level basketball players submitted to a 5-month training period were able to improve their physical-motor indicators and specific skills.
篮球是一项团队运动，运动方式短、强度高，运动方向变化快、频繁。除了特定的技术技巧外，力量、敏捷和速度是篮球运动员取得好成绩的必要条件。本研究旨在验证传统训练周期对青少年篮球运动员身体运动指标及特定技术技能的影响。19名青少年篮球运动员(15.4±1.3岁)，至少有12个月的训练经验，进行5个月的分期研究。我们在训练前和训练后评估了两项身体运动指标(反动作跳跃(CMJ)和无氧能力(直线训练))和两项具体技术技能(运球和投篮)。使用配对学生t检验来检验训练对身体运动变量和技术技能的影响。计算各变量平均相对增益的95%置信区间(Δ%)，并通过Cohen’s d分析效应量(p≤0.05)。在CMJ的PRE和POST矩之间存在显著差异(34.02 vs. 38.64 cm;p <0.001)，在Line-Drill中(33.20 vs. 31.73 s;p <0.001)，运球(6.95 vs. 6.66 s;p <0.001)，射门(15.84比17.95分;p < 0.001)。经过5个月的训练，青少年篮球运动员的身体运动指标和特定技能得到了提高。

ABSTRACT The purpose of this study was to identify structures for the practice of physical activities (PA) in Brazilian Schools and relate them to the Human Development Index (HDI), Basic Education Development Index (IDEB) and quality indicators from the Report Card Brazil (RCB). This is a descriptive study that used secondary data from INEP-Brazil to identify and classify structures for the practice of PA in Brazilian schools based on the presence of “schoolyards”, “sports courts” and “sporting materials”, organized by elementary and high schools. Data were organized by Macroeconomic Region and related to HDI, IDEB and Report Card Brazil Quality Classification Criteria. Thus, for “Elementary School”, positive and significant relationship was observed between HDI and the presence of “schoolyards” (r=0.53; p=0.004), “sports courts” (r=0.855; p<0, 01) and “sporting materials”(r=0.764; p<0.01), while for IDEB, values followed the same logic, associated to the presence of “schoolyards” (r=0.475; p=0.01), “sports courts” (r=0.676; p<0.01) and “sporting materials” (r=0.535; p<0.01). For “High School”, relationship was observed between HDI and the presence of “sports courts” (r=0.517; p<0.01) and “sporting materials” (r=0.499; p<0.01), while for IDEB, relationship was only observed with the presence of “sporting materials” (r=0.508; p<0.01). It could be concluded that the Northern and Northeastern regions of Brazil have schools with lower presence of structure for the practice of Physical Activity and that there is positive relationship of this structure with HDI, IDEB and quality indicators of the Report Card Brazil.

abstract It is known that cardiovascular risk is increased during exercise and recovery. Thus, it is necessary to assess all the risk associated with exercise to minimize the possibility of cardiovascular events. The aim of this study was to verify whether a maximal exercise alters ambulatory cardiac autonomic modulation in untrained women and whether aerobic fitness is correlated to cardiac autonomic modulation. Twelve women (25.35 ± 5.44 years) were outfitted with the Holter monitor on an experimental (after maximum exercise) and a control day to heart rate variability (HRV) evaluation. Maximal exercise increased 24 h heart rate (82 ± 14 vs 77 ± 11 bpm; p = 0.04) and during sleep time (72 ± 14 vs. 65 ± 9 bpm; p = 0.01), reduced parasympathetic modulation (HF – n.u. 49.96 ± 11.56 vs 42.10 ± 14.98; p = 0.04), and increased low-frequency/high-frequency ratio (2.88 ± 3.24 vs 1.31 ± 0.60; p = 0.03) during sleep time compared to the control day. Aerobic fitness was correlated positively with LF, HF, and HF (n.u.) indices (r = 0.61 to 0.73, p < 0.05) and correlated negatively with LF (n.u.) and LF/HF ratio (Rho = - 0.57 to - 0.69; p < 0.05). Maximal exercise alters parasympathetic modulation during sleep time in untrained women. Ambulatory cardiac autonomic modulation after exercise is related to aerobic fitness.
众所周知，在运动和恢复过程中，心血管疾病的风险会增加。因此，有必要评估与运动相关的所有风险，以尽量减少心血管事件的可能性。本研究的目的是验证最大运动是否会改变未经训练的女性的动态心脏自主调节，以及有氧适能是否与心脏自主调节相关。12名女性(25.35±5.44岁)在实验(最大运动后)和对照日配备霍尔特监测仪进行心率变异性(HRV)评估。最大运动增加24小时心率(82±14 vs 77±11 bpm);P = 0.04)和睡眠时间(72±14比65±9 bpm;p = 0.01)，副交感神经调节降低(HF - n.u: 49.96±11.56 vs 42.10±14.98;P = 0.04)，低频/高频比值增加(2.88±3.24 vs 1.31±0.60;P = 0.03)。有氧适宜度与LF、HF和HF (n.u)指数呈正相关(r = 0.61 ~ 0.73, p < 0.05)，与LF (n.u)和LF/HF比呈负相关(Rho = - 0.57 ~ - 0.69;P < 0.05)。在未受过训练的女性中，最大运动改变睡眠期间的副交感神经调节。运动后动态心脏自主调节与有氧适能有关。

Abstract Manipulation of resistance training variables has been shown to have a substantial effect on muscular adaptations. A major variable in this process is exercise selection. In addition to the effectiveness of a given exercise to recruit the target muscle groups, safety considerations and individual comfort during execution of a lift should be considered. The correct biomechanics of the chosen exercise will assist in promoting desired muscle adaptations, while proper safety procedures will reduce risk of injury. Lifting comfort will facilitate enjoyment and foster adherence to the program. Therefore, the purpose of this paper was to offer guidelines for selection of resistance training exercises based on the Efficiency, Safety, and Comfort Analysis Method (ESCAM).

ABSTRACT Due to the high incidence of breast cancer worldwide, it is important to research and understand the physiological and psychological effects of this disease, like fatigue, depression, and capacity to do daily life tasks and how they modify physical activity. This study aimed to analyze the effects of strength training practice on physical fatigue (IMF-20), depression (Beck questionnaire), handgrip strength, and functional performance (time up and go). The sample was composed of 17 women breast cancer survivors, in which 8 volunteers were strength training practitioners for at least 6 months (P), and 9 volunteers were non-practitioners (NP). The T-test identified significant differences (p>0.05) between groups on fatigue (P=7.37±1.76; NP= 10.77±3.41; p=0.02) and depression (P= 8.75±5.20; NP= 14.55±4.21). There was no significant difference between groups on handgrip strength and functional performance.

Abstract Although sedentary behavior (SB) is related to the development of metabolic diseases, there is still no consensus in literature about the association between accelerometer-based SB and obesity, especially adjusted for cardiovascular risk factors and level of daily physical activities. The aim was to evaluate the association between obesity and SB adjusted for potential confounders in adults. Data from 780 participants of the Epidemiology and Human Movement (EPIMOV) Study were analyzed. Body weight, body mass index (BMI), and fat body mass as percentage (%FBM) (bioelectrical impedance) were obtained and, then, used to stratify participants. SB was objectively measured using triaxial waist-worn accelerometers placed above the dominant hip during waking hours for at least four consecutive days (4-7 days). SB and its pattern were not significantly different between obesity groups. Although SB presented some significant correlations with obesity, the correlation and determination coefficient indicated weak association between SB and obesity (e.g., BMI and %FBM). Obesity presented little or no association with SB and its pattern after adjustment for potential confounders, especially when SB is measured through accelerometry.

Obesity presented little or no association with SB and its pattern after adjustment for potential confounders, especially when SB is measured through accelerometry.","PeriodicalId":38989,"journal":{"name":"Revista Brasileira de Cineantropometria e Desempenho Humano","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85837113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

abstract – This paper is an update of the systematic review on Active Play published in 2018 by Mendes et al. This systematic review included studies published between 2018 and 2019. The search for potential articles was performed on the following electronic databases: Pubmed/Medline, Web of Science, Bireme, Scielo and Scopus. Initially, 471 papers met the eligibility criteria. However, after deeply analyzed, only two studies remained and were included in the present review. From these articles only one presented individual information on play activity among adolescents age (12-17 years) from Curitiba-PR and it reveals that 77,2% of them were physically active in their free time. The other study included was about the preferences for leisure activities among adolescents from Florianopolis-SC participants in two cross sectional studies in 2001 and 2011. It showed a significant reduction in the preferences for practicing physical activities, while the opposite occurs with sedentary activities like watching TV, playing video games, and using computers. These results along with the inconsistencies in benchmarks of the domain active play among countries involved in the Global Matrix 3.0 made clear the necessity of a standard definition and a proper tool to measure it.
本文是Mendes等人在2018年发表的关于主动游戏的系统综述的更新。该系统综述包括2018年至2019年发表的研究。在以下电子数据库中搜索潜在文章:Pubmed/Medline, Web of Science, Bireme, Scielo和Scopus。最初，有471篇论文符合资格标准。然而，经过深入分析，只剩下两项研究，并纳入本综述。在这些文章中，只有一篇文章介绍了库里蒂巴-公里岛12-17岁青少年的游戏活动情况，其中77.2%的人在空闲时间进行体育活动。另一项研究包括2001年和2011年两项横断面研究中来自弗洛里亚诺波利斯- sc的青少年对休闲活动的偏好。研究显示，人们对体育锻炼的偏好显著降低，而对看电视、玩电子游戏和使用电脑等久坐不动的活动的偏好则相反。这些结果以及参与全球矩阵3.0的国家之间的领域积极作用基准的不一致表明，有必要制定一个标准定义和一个适当的工具来衡量它。

ABSTRACT We analyzed the effect of obesity on daily physical activity (DPA), light-intensity physical activity (LPA), moderate-intensity physical activity (MPA) and vigorous- intensity physical activity (VPA) in children and adolescents. Overall, 462 students from a public school (53.6% boys; aged 7-12 years) were involved in this one-year longitudinal study. Physical activities and sedentary behaviors (SB) were reported in the questionnaire Food Intake and Physical Activity of Students (Web-CAAFE). Obesity was evaluated through Body Mass Index (BMI z score ≥ 2). Obesity was observed in 16.5% of participants, but it did not influence LPA, MPA or DPA. However, VPA were 20% less frequent among obese students (β2=0.80; CI 95%: 0.66-0.98). Obese girls showed less frequency of VPA than non-obese boys (Mean Difference = -0.97; CI 95%: -1.36 to -0.57). Non-obese girls showed less VPA than non-obese boys (Mean Difference = -1.18; CI 95%: -1.40 to -0.95) and obese ones (Mean Difference = -0.57; CI 95%: -0.90 to -0.24). Obese boys showed fewer VPA, if compared to non-obese ones (Mean Difference = -0.61; CI 95%: -0.96 to -0.26). The analysis of the obesity-sex-age interaction showed a greater reduction in VPA among obese girls aged 10 years or more when compared to obese girls aged 7-9 years, and among boys obese and non-obese regardless of age. Amounts of VPA and SB increased simultaneously among non-obese boys and non-obese children aged 7-9 years. Obesity reduced VPA in the sample during the follow up of one year, independently of age and SB.

Abstract The present study examined the effects of small-sided and conditioned games (SSCGs) manipulating tactical rules (ball-possession [BP] vs goal-scoring with goalkeepers [GS]) and pitch size (square [SP] vs rectangular [RP]) on the running performance and technical skills of young soccer players. Ten male soccer players (chronological age: 12.45 ± 0.51 years; body mass: 41.99 ± 7.97 kg; height: 152.85 ± 10.03 cm) were monitored using GPS units during SSCG formats. The distance covered at different running intensities and number of technical actions were used in analyses. SSCG-induced changes in 30 m sprint and CMJ performances were also evaluated. Compared to BP, GS elicited significantly lower distances covered at low intensity running (p=0.003; d=-0.95), more sprints (p=0.050; d=0.67), and longer distances covered in terms of walking (p=0.035; d=2.60) and sprinting (p=0.029; d=0.75); (ii) number of passes (short [p=0.002; d=1.10] and long [p=0.013; d=0.82]) were more frequent during BP than GS games, while RP game format allowed for greater occurrence of long passes (p=0.036; d=0.64) than under the SP condition; (iii) jumping and sprinting performance did not change (p>0.05) using different SSCG formats. In conclusion, GS games demand more sprint running episodes in terms of number and distance covered than BP games. In addition, RP game formats can be used to increase the occurrence of longer passes in young soccer players aged 11-13 years.
