- Aim: To analyze the prevalence of risky behaviors among physical education undergraduates; to determine prevalence of risk factors for non-communicable chronic diseases (NCCD) among university, and; to determine the association between healthy life habits and physical activity. Method: A cross-sectional study with 903 undergraduate Physical Education students. The study used a self-administered questionnaire on health-related life habits. All questions were obtained from the Surveillance of Risk and Protection Factors for Chronic Diseases through Telephone Interviews. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI). Results: Of the 903 students, 57.4% were women, 67.6% were between 20-29 years of age, 68.7% consumed alcohol, 28.5% did not do physical activity, and 33.2% were overweight. Regarding the eating habits considered a risk for NCCD, women exhibited more risk factors than men, whereas 41.1% drank more full-fat milk (p = 0.01) and 31.8% ate more fatty meats, while men drank more soda (p < 0.01). Physically active students consumed more fruits (p < 0.01) and salads (p = 0.01) and drank less soda (p < 0.01). The physically inactive students had a high prevalence of getting diabetes (p < 0.01) and of suffering from hypertension (p = 0.01) and high cholesterol (p < 0.01). Conclusions: University students in our study had unhealthy lifestyles. There is an urgent need for both a formulation and implementation of public health policies to promote health and decrease risk factors for NCCD.
目的:分析体育本科学生危险行为的发生情况;确定大学生中非传染性慢性疾病风险因素的流行情况;确定健康生活习惯与体育活动之间的关系。方法:对903名体育专业本科生进行横断面调查。这项研究使用了一份有关健康生活习惯的自我管理问卷。所有问题均通过电话访谈从慢性病风险与保护因素监测中获得。采用Logistic回归估计优势比(OR)和95%置信区间(95% CI)。结果:903名学生中,57.4%为女性,67.6%年龄在20-29岁之间,68.7%饮酒,28.5%不运动,33.2%超重。在被认为是NCCD危险因素的饮食习惯方面,女性表现出比男性更多的危险因素,41.1%的人喝更多的全脂牛奶(p = 0.01), 31.8%的人吃更多的肥肉,而男性喝更多的苏打水(p < 0.01)。积极运动的学生食用水果(p < 0.01)和沙拉(p = 0.01)较多,饮用苏打水较少(p < 0.01)。缺乏体育锻炼的学生糖尿病患病率(p < 0.01)、高血压患病率(p = 0.01)、高胆固醇患病率(p < 0.01)较高。结论:本研究的大学生存在不健康的生活方式。迫切需要制定和实施公共卫生政策,以促进健康和减少非传染性疾病的危险因素。

Aim: This study aimed to test the influence of functional improvements in volleyball skills performance. Methods: Twenty-eight amateur female volleyball players were assigned to Skill (S: n = 14, 19.5 ± 4.6 yrs; 169.7 ± 7.2 cm; 62.9 ± 12.7 kg) or Skill and Strength/Power (S+SP: n = 14; 18.6 ± 3.5 yrs; 169.7 ± 5.1 cm; 63.3 ± 9.2 kg). S +SP performed eight weeks of volleyball and conditioning training. S maintained only volleyball training. Functional variables (i.e. strength, power, and agility measures) and volleyball skills performance in a game-situation context were assessed before and after training. Results: 1-RM squat and bench press, time at modified agility T-test, peak power at bench throw and medicine-ball throw distance improved for the S+SP (p<0,05). S group increased only in medicineball throw distance (p<0.05). There were no differences between groups in the functional variables tested (p>0.05). The probabilities of a perfect set and an attack ‘kill’ in S+SP improved (¶>0.90). Changes from pre to post-training were higher in S+SP than in S for a perfect set, ‘stuff block’ and defense with displacement (¶>0.90).Conclusion: Our data suggest that functional improvements may positively affect volleyball skills performance. Although functional variables revealed only within-group changes, S+SP produced greater improvements in skill performance than S, supporting the use of conditioning training to improve volleyball performance.
目的:探讨功能改善对排球技术成绩的影响。方法:28名业余女排运动员(S: n = 14, 19.5±4.6;169.7±7.2 cm;62.9±12.7 kg)或技能和力量/力量(S+SP: n = 14;18.6±3.5岁;169.7±5.1 cm;63.3±9.2千克)。S +SP进行了8周的排球和体能训练。S只坚持排球训练。功能变量(即力量、力量和敏捷性测量)和排球技术在训练前后的游戏情境下的表现进行了评估。结果:S+SP的1-RM深蹲和卧推、修正敏捷性t检验时间、卧投峰值力量和投球距离均有显著提高(p0.05)。S+SP中完美集合和攻击'击杀'的概率提高(¶>0.90)。在S+SP中,从训练前到训练后的变化高于S的完美组合,'材料阻挡'和位移防御(¶>0.90)。结论:我们的数据表明,功能的改善可能会积极影响排球技术的表现。虽然功能变量只显示组内变化,但S+SP在技术表现上比S产生了更大的改善,支持使用条件训练来提高排球成绩。

Aims: Movement specific warm-up is a widely accepted practice in the sports environment; however, little is known regarding the ideal intensity of its performance. To verify the effects of adding high-intensity sets to the warm-up on strength, muscular electrical activity, and body temperature in the bench press exercise. Methods: Twelve men (21±1.7 years, 23.9±3.5 kg.m2) were evaluated by a maximal repetition test (1-RM), after which the volunteers performed three procedures: Low-intensity warm-up (LIW), low-intensity warm-up with high-intensity sets (WHI), and no warm-up (CON). Next, they performed maximal isometric voluntary contractions (MIVC) of the chest press to assess the electromyographic activity of the pectoralis major, peak rate of force, development (RFDpeak), and maximum strength (Smax). The skin temperature was evaluated before starting the test. Results: No between-condition differences (p≤0.05) were found for Smax (CON = 320.3±83.8 N; LIW = 300.1±131.6 N, HIW = 327.0±113.9 N; p = 0.689), RFDpeak (CON = 4399±1776 Ns-1; LIW = 3476±1905 Ns-1; HIW = 4715±2184 Ns-1; p = 0.243), skin temperature (CON = 34.0 ±1.0 °C, LIW = 34.9±0.8 °C, HIW = 34.8±1.1 °C; p = 0.078) or myoelectric activity according to the root mean square index of sternocostal (p = 0.402) and clavicular (p = 0.535) heads, as well as the median frequency data of sternocostal (p = 0.169) and clavicular heads (p = 0.456). Conclusion: In conclusion, the proposed warm-up protocols were not able to modify strength, muscle electrical activity, or skin temperature in the bench press exercise.
目的:特定动作热身是运动环境中被广泛接受的做法;然而,人们对其性能的理想强度知之甚少。为了验证在热身中增加高强度组对力量、肌肉电活动和卧推运动体温的影响。方法:对12名男性(21±1.7岁,23.9±3.5 kg.m2)进行最大重复测试(1-RM),然后进行低强度热身(LIW)、低强度热身加高强度训练(WHI)和不热身(CON)三个步骤。接下来,他们进行了最大等长自主收缩(MIVC)的胸压,以评估胸大肌的肌电图活动、力的峰值速率、发展(RFDpeak)和最大力量(Smax)。在试验开始前评估皮肤温度。结果:Smax (CON = 320.3±83.8 N;Liw = 300.1±131.6 n, hiw = 327.0±113.9 n;p = 0.689), RFDpeak (CON = 4399±1776 Ns-1;LIW = 3476±1905 Ns-1;HIW = 4715±2184 Ns-1;p = 0.243),皮肤温度(CON = 34.0±1.0℃,LIW = 34.9±0.8℃,HIW = 34.8±1.1℃;P = 0.078)或根据胸肋头(P = 0.402)和锁骨头(P = 0.535)的均方根指数以及胸肋头(P = 0.169)和锁骨头(P = 0.456)的中位数频率数据进行肌电活动。结论:总之,提出的热身方案不能改变卧推运动中的力量、肌肉电活动或皮肤温度。

Aim: To investigate the consequences of chronic eccentric exercise in histopathology, inflammatory, and myogenic regulatory factors response in gastrocnemius muscle of X-chromosome-linked muscular dystrophy (mdx) mice. Method: Male mdx and control mice (C57BL/10 lineage) were distributed in the following groups: Sedentary Control (SC), Trained Control (TC), Sedentary Mdx (S-Mdx), and Trained Mdx (T-Mdx). Trained animals were subjected to downhill running for 7 weeks. Gastrocnemius was submitted to histopathological analysis and immunoexpression of Cyclooxygenase-2 (COX-2) and myogenic regulatory factors (myoD and myogenin). Results: The exercise influenced inflammation response as demonstrated by the increased COX-2 immunoexpression in T-Mdx. Interestingly, Myogenic regulatory factors revealed that the lack of dystrophin has not been influenced myoD and the increase of myogenin occurred due to exercise and was not aggravated by the absence of dystrophin. Conclusion: In conclusion, an eccentric exercise in gastrocnemius of mdx mice was characterized by an intense inflammatory process without myogenic response. These findings suggest that special attention should be given to inflammatory aspects related to COX-2 associated with a decrease of myoD expression, as biomarkers in motor rehabilitation programs.
目的:探讨慢性偏心运动对x染色体连锁性肌营养不良(mdx)小鼠腓肠肌组织病理学、炎症和肌生成调节因子反应的影响。方法:雄性mdx和对照小鼠(C57BL/10系)分为久坐对照组(SC)、训练对照组(TC)、久坐mdx (S-Mdx)和训练mdx (T-Mdx)。训练后的动物进行7周的下坡跑。对腓肠肌进行组织病理学分析和环氧化酶-2 (COX-2)和肌生成调节因子(myoD和myogenin)的免疫表达。结果:运动影响了T-Mdx的炎症反应,表现为COX-2免疫表达增加。有趣的是,肌生成调节因子显示,肌营养不良蛋白的缺乏并没有影响肌od,肌生成素的增加是由于运动引起的,并没有因肌营养不良蛋白的缺乏而加剧。结论:综上所述,mdx小鼠腓肠肌偏心运动具有强烈的炎症过程,无肌源性反应。这些发现表明,应特别关注与COX-2相关的炎症方面,并将其作为运动康复计划中的生物标志物,与myoD表达减少相关。

Method: Male mdx and control mice (C57BL/10 lineage) were distributed in the following groups: Sedentary Control (SC), Trained Control (TC), Sedentary Mdx (S-Mdx), and Trained Mdx (T-Mdx). Trained animals were subjected to downhill running for 7 weeks. Gastrocnemius was submitted to histopathological analysis and immunoexpression of Cyclooxygenase-2 (COX-2) and myogenic regulatory factors (myoD and myogenin). Results: The exercise influenced inflammation response as demonstrated by the increased COX-2 immunoexpression in T-Mdx. Interestingly, Myogenic regulatory factors revealed that the lack of dystrophin has not been influenced myoD and the increase of myogenin occurred due to exercise and was not aggravated by the absence of dystrophin. Conclusion: In conclusion, an eccentric exercise in gastrocnemius of mdx mice was characterized by an intense inflammatory process without myogenic response. These findings suggest that special attention should be given to inflammatory aspects related to COX-2 associated with a decrease of myoD expression, as biomarkers in motor rehabilitation programs.","PeriodicalId":153884,"journal":{"name":"Motriz: Revista de Educação Física","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123985841","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}

Aim: To verify the association between sociodemographic, academic background, professional performance, bibliographic production and training of human resources factors with the H Index of CNPq scientific productivity researchers in the field of Physical Education. Methods: This cross-sectional study included 94 researchers with scientific productivity grants (PQ) in the field of Physical Education in Brazil distributed into academic prestige level: PQ 1A-1D (n = 41) and PQ 2 (n = 53). For this, the H Index of these researchers was analyzed in the Scopus database. Related factors were sociodemographic, academic background, professional performance, bibliographic production, and training of human resources (student supervisor). Simple and multiple linear regression was used with a 5% significance level. Results: The H Index, number of citations, number of scientific articles in the last 10 years, number of books in the last 10 years, and the training of students at graduate levels of PQ 1A-1D was higher than that of PQ 2 (p <0.05). The H Index of PQ 1A-1D scholarship researchers was directly related to the number of scientific articles [H index = 8.48 + 0.11 * (Articles)]. The H index of PQ 2 scholarship researchers was directly related to the number of scientific articles and academic books and, inversely to the student supervision at master level [H index = 15.19 + 0.06 * (Articles) + 2.45 * (Books) 0.34 * (Masters)]. Conclusion: H Index of researchers in the field of Physical Education in Brazil varied according to the academic recognition level.
目的:验证社会人口学、学术背景、专业表现、文献产出和人力资源要素培训与CNPq体育科研人员科学生产力H指数的关系。方法:本横断面研究包括94名巴西体育领域获得科学生产力补助金(PQ)的研究人员,分为学术声望级别:PQ 1A-1D (n = 41)和PQ 2 (n = 53)。为此,我们在Scopus数据库中对这些研究者的H Index进行了分析。相关因素有社会人口统计学、学术背景、专业表现、文献制作和人力资源(学生导师)培训。采用简单和多元线性回归,显著性水平为5%。结果:pq1a - 1d的H指数、近10年的被引次数、近10年的科学论文数量、近10年的图书数量、研究生培养水平均高于pq2 (p <0.05)。PQ 1A-1D奖学金研究人员的H指数与科研论文数量直接相关[H指数= 8.48 + 0.11 *(文章)]。PQ 2奖学金研究人员的H指数与科研论文和学术书籍的数量正相关,与硕士水平的学生监督成反比[H指数= 15.19 + 0.06 *(文章)+ 2.45 *(书籍)0.34 *(硕士)]。结论:巴西体育研究人员的H指数随学术认知水平的不同而不同。
