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.","PeriodicalId":153884,"journal":{"name":"Motriz: Revista de Educação Física","volume":"50 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":"115532030","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}

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.","PeriodicalId":153884,"journal":{"name":"Motriz: Revista de Educação Física","volume":"37 6 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":"128232088","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}

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).

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}

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)].
