Influence of quarantine during the coronavirus disease 2019 (COVID-19) pandemic on physical and psychosocial aspects: perceptions of 214 Brazilian athletes.

Background: Social distancing may affect athletes' training, causing negative effects on mental and physical health. Objective: This study therefore aimed to characterize the perception of Brazilian athletes about their physical and psychosocial aspects, sleep quality and coping strategies during the quarantine of the coronavirus disease 2019 (COVID-19) pandemic. Methods: This was a cross-sectional study with online survey, performed with Brazilian athletes (amateur and professional) over 18 years. The main outcomes measures assessed were physical and psychosocial aspects, sleep quality and coping strategies. Results: A total of 214 athletes were included. The average weekly hours of training during the quarantine was 4.71 ± 3.71 h, of which 64.5% athletes (138/214) were oriented by medical staff during training. For 52.8% (113/214) of athletes, training intensity during the quarantine was different/very different from the intensity before the quarantine. 79.4% athletes (170/214) reported moderate to extreme difficulties in keeping the same level of training during the quarantine. 77.1% athletes (165/214) had moderate to extreme anxiety and each of the athletes had concern about his or her athletic career future, including return to the sport. 72.9% athletes (156/214) reported change in sleep schedule during the quarantine period. Conclusion: The quarantine period during COVID-19 pandemic negatively affected the athlete's perception about training routine, since athletes reported reduction in training hours and training intensity. Overall, the athletes reported that they were moderately to extremely anxious. They also had concerns about their career in the future, as well as concerns regarding return to sport.

Can running influence women's sexual function?

INTRODUCTION AND HYPOTHESIS: Studies have shown that athletes have three times increased risk of urinary incontinence compared to non-athletes, in addition to anal incontinence and sexual dysfunction (SD). This study aimed to assess the sexual and pelvic floor muscle (PFM) functions and to compare these variables among female athlete runners with and without SD and to identify predictive factors that may be associated with sexual function among the athletes. METHODS: Cross-sectional study including 90 female runners, who ran ≥ 20 km/week for at least 6 months, had had sexual intercourse in the last 4 weeks and were > 18 years old. PFM function was assessed by vaginal palpation and manometry. Women also answered the International Consultation on Incontinence Questionnaire-Short Form to investigate presence of urinary incontinence. Sexual function was assessed by Female Sexual Function Index (FSFI); total scores ≤ 26.5 were considered to indicate SD. The scores of each FSFI domain and the total score were compared individually between each predictor using simple linear regression. In addition, multiple linear regression analysis was performed. RESULTS: Athletes with SD presented lower PFM strength. The results of the multiple linear regression analysis among all the predictor variables, FSFI domains and total score show that the Modified Oxford Scale is a predictor for the desire, excitation, lubrication, orgasm, pain and total score domains. CONCLUSIONS: Female runners with lower PFM strength presented worse sexual function regardless of age, parity, BMI and running practice time.

Is the isometric strength of the shoulder associated with functional performance tests in overhead athletes?

OBJECTIVE: To verify the association of the isometric strength of the shoulder external rotators (ER) and serratus anterior (SA) with the performance of functional tests CKCUEST, SMB-T, and USSP-T in overhead athletes. DESIGN: Cross-sectional study. PARTICIPANTS: Eighty overhead athletes with no history of surgery in the upper and lower limbs and trunk in the past year, and no painful symptoms in the upper body during the physical assessment were included. MAIN OUTCOME MEASURES: Preseason assessment included isometric strength of shoulder ER and SA, and performance of the CKCUEST, SMB-T, and USSP-T. Multiple linear regression analysis was performed to identify if the isometric strength of the shoulder ER and SA could explain the performance during the tests after controlling for sex. RESULTS: The isometric strength of SA was associated (p < 0.05) with the SMB-T and USSP-T with 4% of explain. The isometric strength of the SA was not associated (p > 0.05) with the CKCUEST. The isometric strength of the ER was not associated (p > 0.05) with any of the tests. CONCLUSION: The isometric strength of the SA predicted the SMB-T and USSP-T performance. Isometric strength of SA and shoulder ER was not associated with CKCUEST results in athletes overhead.

Resumo O artigo busca analisar o desempenho do financiamento coletivo (crowdfunding) como estratégia de arrecadação de recursos para a campanha eleitoral a deputado federal nas eleições de 2018. Também foi analisada a influência de características socioeconômicas e demográficas dos candidatos associada à decisão de adoção do financiamento coletivo como alternativa arrecadatória na campanha eleitoral. A metodologia utilizada foi a de regressão logística, considerando as seguintes variáveis independentes: valores arrecadados, escolaridade, idade, raça e estado civil do candidato, além de ideologia, tamanho e antiguidade do partido. As variáveis dependentes binárias foram: utilização ou não do crowdfunding e sucesso ou insucesso eleitoral. A fonte de dados foi o repositório de dados eleitorais do Tribunal Superior Eleitoral (TSE), com informações de todos os candidatos a deputado federal, de todos os estados brasileiros, no pleito de 2018. Entre os resultados obtidos, encontra-se que o crowdfunding foi estatisticamente mais usado por candidatos brancos, jovens, de alta escolaridade e da região Sul. Há evidências também de que o crowdfunding seja uma estratégia eleitoral utilizada sobretudo por candidatos de partidos de criação recente, de esquerda, centro-esquerda ou de direita - os de centro e centro-direita tiveram menor utilização -, e daqueles com maior bancada. Por fim, o modelo econométrico aponta um acréscimo médio de 5,55 pontos percentuais na probabilidade de sucesso eleitoral dos candidatos que se valeram do crowdfunding.

Abstract The article seeks to analyze the performance of crowdfunding as a fundraising strategy in the election campaign for the Brazilian Congress in the 2018 general elections. The article also analyzes the influence of the socioeconomic and demographic profiles of the candidates associated with the decision to adopt crowdfunding. The methodology used was logistic regression, considering the following independent variables: funds raised, education, age, race, and marital status of the candidate, in addition to the party's ideology, size, and age of the party. The binary dependent variables were: use of crowdfunding (or not) and the campaign's outcome. The data source was the Electoral Data Repository of the Brazilian Superior Electoral Court (TSE), with information from all candidates running for federal deputy in all Brazilian states in the 2018 general elections. The resulting analysis shows that crowdfunding was statistically more used by white, young, highly educated candidates from the Southern region of Brazil. There is also evidence that crowdfunding is an electoral strategy used especially by candidates from recently created parties, from the left, center-left or right (those in the center and center-right did not use crowdfunding as frequently) and larger parties. Finally, the econometric model points to an average increase of 5.55 percentage points in the probability of electoral success of candidates using crowdfunding.

Isokinetic dynamometry on the internal rotator and adductor muscles of the swimmers' shoulders: no differences between asymmetrical and symmetrical swimming strokes / Dinamometria isocinética dos músculos rotadores internos e adutores dos ombros de nadadores: sem diferenças entre braçadas de nados assimétricos e simétricos

OBJECTIVE: In this study, we compare muscular strength of the internal rotators and adductors of the shoulder between asymmetrical (backstroke and freestyle) and symmetrical (breaststroke and butterfly) swimming strokes. METHOD: We evaluated: shoulders of (a) asymmetrical swimmers (aged 21.8 ± 3.8 years), (b) symmetrical swimmers (aged 20.3 ± 4.5 years), (c) recreational swimmers (aged 24.5 ± 4.5 years), and (d) control individuals (aged 25.8 ± 3.5 years). All evaluations were performed on a Biodex® isokinetic dynamometer at velocities of 60° and 300°/second. Adduction and internal rotation movements were evaluated. The variables studied were peak torque corrected for body weight (PTQ/BW), total work (TW) and the agonist/antagonist relationship. RESULTS: There were no differences in adductor strength between the symmetrical and asymmetrical swimmers regarding PTQ/BW (symmetrical: 114.4 Newto-meter vs. asymmetrical: 109.4 Newton-meter) and TW (symmetrical: 642.9 Joules; asymmetrical: 641.5 Joules). There was no difference in the abduction/adduction relationship between the symmetrical (67.4%) and asymmetrical (68.3%) swimmers. There was no difference in the internal rotator musculature between the symmetrical and asymmetrical swimmers regarding the variables PTQ/BW (symmetrical = 66.4 Newton-meter and asymmetrical = 63.4 Newton-meterm) and TW (symmetrical = 517.4 J and asymmetrical 526.7 J). There was no difference in the ratio of external to internal rotation of the shoulder between the symmetrical (65.7%) and asymmetrical (61.5%) swimmers. CONCLUSIONS: There were no differences in muscular strength in the adductor and internal rotator muscles of the shoulder between symmetrical and asymmetrical swimming strokes.

RESUMO OBJETIVO: Neste estudo, comparamos a força muscular dos músculos rotadores internos e dos adutores do ombro entre nadadores especializados em estilos assimétricos (costas e nado livre) e simétricos (nado peito e borboleta).

As avaliações foram realizadas em um dinamômetro isocinético Biodex® nas velocidades de 60° e 300° / segundo. Foram avaliados adução e movimentos de rotação interna. As variáveis estudadas foram o pico de torque corrigido para peso corporal (PTQ/BW), trabalho total (TT) e a relação agonista/antagonista. RESULTADOS: Não houve diferenças na força adutora entre os nadadores simétricos e assimétricos em relação PTQ/BW (simétricos: 114,4 newton-metro vs. assimétricos: 109,4 newton-metro) e TW (simétrica: 642,9 Joules; assimétrica: 641,5 Joules). Não houve diferença na relação abdução/adução entre nadadores simétricos (67,4%) e assimétricos (68,3%). Não houve diferença na musculatura rotadora interna entre o nadadores simétricos vs. assimétricos em relação às variáveis PTQ/BW (simétricos = 66,4 Newton-metro e assimétricos = 63,4 Newton-metro) e TW (simétricos = 517,4 J e assimétricos 526,7 J). Não houve diferença na relação de rotação externo para interno do ombro entre nadadores simétricos (65,7%) e assimétricos (61,5%). CONCLUSÕES: Não houve diferenças na força muscular dos músculos adutores e rotadores internos do ombro entre estilos de natação simétricos e assimétricos.

The effects of motor learning on clinical isokinetic performance of postmenopausal women.

OBJECTIVE: To analyze the effects of motor learning on knee extension-flexion isokinetic performance during clinical isokinetic evaluation of postmenopausal women. METHODS: One-hundred and twenty postmenopausal women (60.3±3.2 years; BMI=27.6±4.7 kg/m(2)) without knee pain or injury and that never underwent isokinetic testing, were submitted to two bilateral knee extension-flexion (concentric-concentric) isokinetic evaluation (5 repetitions) at 60°/s (Biodex™ Multi-Joint System 3 dynamometer). The tests were first performed in the dominant leg, with a 1-min recovery between them, and after a standardized warm-up that included 3 submaximal isokinetic repetitions. The same procedure was repeated in the non-dominant leg. Peak torque (PTQ) was adjusted for body weight (PTQ/BW), total work (TW), coefficient of variation (CV) and agonist/antagonist (agon/antag) ratio was compared between tests. RESULTS: Subjects showed greater levels (P<0.001) of PTQ, PTQ/BW and TW, and lower CV levels (P<0.01) in test 2 of both legs. Agon/antag ratio did not change significantly between tests. CONCLUSIONS: PTQ, PTQ/BW, TW and CV improved in the second knee extension flexion isokinetic testing of postmenopausal women. The results suggests that performing two tests, even with a short period of recovery between them, could be considered for reducing motor learning effects on clinical isokinetic evaluation of knee joint in postmenopausal women.

A eletromiografia tem sido utilizada para avaliar o controle voluntário da atividade muscular. Dentre as técnicas destaca-se o biofeedback eletromiográfico como facilitador do aprendizado neuromotor, inclusive na prática esportiva. Objetivo: Analisar o efeito do biofeedback eletromiográfico nos parâmetros isocinéticos dos flexores e extensores do joelho e inversores e eversores do tornozelo em jogadores de futebol amador. Casuística: 14 atletas de futebol amador do gênero masculino randomizados em dois grupos: Grupo Treino (GT) - sete atletas, idade de 23 ± 2 (22 e 28) anos, massa corpórea 75,7 ± 4,0(72 e 80) kg , estatura 182 ± 4 (176 e 188) cm e Grupo Controle (GC) - sete atletas com idade 24 ± 2 (21 e 28) anos, massa corpórea 72,3± 9,4 (59 e 79) kg, estatura 175± 5 (169 e 180) cm. Método: Todos os atletas foram avaliados por um protocolo clínico: anamnese, incidência de lesões e escala visual análoga de dor e foram submetidos à dinamometria isocinética dos inversores e eversores do tornozelo e flexores e extensores do joelho. O GT realizou 12 sessões de biofeedback eletromiográfico, uma vez por semana. No final das sessões, todos os atletas foram reavaliados. Resultados: Na velocidade de 30º/ seg., o pico de torque 0,18 segundos (PT 0,18s) dos eversores do tornozelo foi maior no GT e no joelho, na velocidade de 60º/seg. o PT 0,18s dos flexores de joelho foram maiores no GT. Conclusão: O biofeedback eletromiográfico melhorou os parâmetros isocinéticos dos jogadores de futebol amador.

Electromyography has been used to evaluate the voluntary control of muscular activity. One of the highlights among the techniques is electromyography biofeedback (EMGBio), which works as a facilitator of neuromotor development, including playing sports. Objective: To analyze the effect of EMGBio within the isokinetic parameters of knee flexion and extension and ankle inversion and eversion in amateur soccer players. Subjects: Two randomized groups of fourteen male amateur soccer players: Training group (TG) - seven athletes, with an age of 23 ± 2 (22 and 28) years old, body mass 75.7kg ± 4.0kg (72 and 80), height 182cm ± 4cm (176 and 188) and Control Group (CG) - seven athletes, with an age of 24 ± 2 (21 and 28) years old, body mass 72.3kg ± 9.4kg (59 and 79), height 175cm ± 5cm (169 and 180). Methods: all athletes were evaluated by a clinical protocol: anamnesis, occurrence of injuries and visual analogue scale of pain and were subjected to knee flexion and extension and ankle inversion and eversion isokinetic dynamometry. The training group had twelve sessions of EMGBio once a week. At the end of the sessions, all athletes were revaluated. Results: At a velocity of 30 deg/s, the ankle eversion peak torque of 0.18 seconds (PT of 0.18s) was higher in the training group and at a velocity of 60 deg/s, the knee flexion PT of 0.18s was higher in the training group. Conclusion: Electromyographic biofeedback improved the isokinetic parameters of the amateur soccer players.

Dinamometria isocinética de tronco em nadadores de diferentes estilos / Isokinetic trunk dynamometry in diferent swimming strokes

OBJETIVOS: Comparar a atividade muscular dos músculos flexores e extensores de tronco entre estilos de nado assimétrico e nado simétrico. MÉTODO: Catorze nadadores da elite, velocistas e especialistas em um dos quatro estilos da natação sem história prévia de lesões.. Divididos em dois grupos de sete atletas: 1. Grupo nado assimétrico (GNA): constituído por cinco atletas que nadam o estilo crawl e dois atletas que nadam o estilo costas. 2. Grupo nado simétrico (GNS) formado por sete atletas: quatro atletas nadadores no estilo peito e três nadadores no estilo borboleta. Todos foram avaliados no dinamômetro isocinético Cybex 6000. RESULTADOS: O tempo de aceleração na velocidade de 120º/ s do grupo flexor do tronco foi maior no GNS (p=0,054). A potência do grupo extensor nas velocidades de 90 e 120º/ segundo foi maior no GNA que no GNS (p=0,053 e 0,052) respectivamente. Não houve diferença estatística significante nas demais variáveis analisadas. CONCLUSÃO: Os nados assimétricos (crawl e costas) proporcionam uma resposta muscular (recrutamento) mais eficiente nos grupo dos flexores do tronco, possivelmente pela manutenção constante da contração isométrica dos músculos abdominais.

OBJECTIVE: To compare the effect of asymmetric and symmetric swimming strokes on muscle activity of the trunk flexor and extensor muscles. METHODS: Fourteen elite speed swimmers, specialists in one of four swimming styles, all without any history of spinal cord injury, were divided in two groups: 1) asymmetric group, consisting of five athletes specializing in the freestyle stroke and three in the backstroke; and 2) symmetric group, consisting of four athletes specializing in the butterfly stroke and three in the breaststroke. All the swimmers were assessed using a Cybex 6000 isokinetic dynamometer. RESULTS: The acceleration time for the trunk flexor group at a speed of 120º per second was greater in the symmetric group (p=0.054). The power of the extensor group at speeds of 90º and 120º per second were greater in the asymmetric than in symmetric group (p=0.053 and 0.052) respectively. There was no significant statistical difference for any of the other variables assessed. CONCLUSION: The asymmetric strokes (crawl and backstroke) provided a more efficient muscular response (recruitment) in the trunk flexor muscles, which may be due to the constant maintenance of isometric contraction of the abdominal muscles.

Modelos organizacionais e reformas da administração pública / Organizational models and public management reforms

Este artigo foi elaborado a partir de uma pesquisa bibliográfica em livros e artigos científicos clássicos ou recentemente publicados na literatura de administração pública na Europa e nos Estados Unidos, e faz uma comparação dos quatro modelos organizacionais e relacionais que vêm inspirando o desenho das estruturas e processos nas recentes reformas da administração pública. Os modelos analisados são o burocrático, a administração pública gerencial, o governo empreendedor e a governança pública. Recentemente, reformas administrativas vêm pregando a substituição progressiva do modelo burocrático weberiano por novos modelos de gestão e de relação do Estado com a sociedade. Este artigo mostra que os novos modelos compartilham características essenciais com o modelo tradicional burocrático e, portanto, não são modelos de ruptura. Também é argumentado que reformas da administração pública transformam-se facilmente em políticas simbólicas, e que políticos e burocratas tentam manipular a percepção do público em relação ao desempenho dos governos. Não são raros os esforços de reforma da administração pública que avançam mais em autopromoção e retórica do que em fatos concretos. Por último, são feitas sugestões para uma agenda de pesquisa àqueles interessados em temas de reformas da administração pública.

This article is based on a bibliographical research both in classic and recently published textbooks and in scientific papers in the literature of public administration in Europe and the United States. Its main objective is to compare the four organizational and relational models that have been inspiring the design of structures and processes in recent public management reforms: the bureaucratic model, the new public management, the entrepreneurial government, and public governance. Recently, there has been a progressive shift from the bureaucratic model to these new organizational and relational models. This article demonstrates that new organizational and relational models share important characteristic with the traditional bureaucratic model and, therefore, are not models of rupture. Also, public management reforms can easily become symbolic policies when politicians and public officials strive to manipulate the public's perception of the administration's performance. Public management reform efforts related to self-promotion and rhetoric rather than to concrete results are a common fact. Finally, the article proposes items for a research agenda for those who are interested in public management.
