RESUMEN
Objetivo: Analisar os aspectos motivacionais associados à prática da corrida de rua em corredores recreacionais do sudoeste do Paraná. Metodologia: Trata-se de um estudo com delineamento transversal e quantitativo. Participaram desta pesquisa 91 corredores recreacionais de ambos os sexos, com idade média de 38,4±10,2 anos. Foram utilizados como instrumentos de coleta de dadosuma ficha de características individuais e o Inventário de Motivação para a Prática de Atividade Física (IMPRAF-126). A Amostra foi dicotomizada em grupo adesão, com menos de um ano de prática e grupo permanência, com mais de um ano de prática. O teste de Friedman, a correção post hocde Bonferronie o teste de U-Mann-Whitney, foram utilizados para avaliar as diferenças entre as dimensões motivacionais. Resultados: A saúde (4,60±0,41) e o prazer (4,41±0,53)se apresentaram como os aspectos motivacionais mais fortes para a prática da corrida de rua, com diferença estatisticamente significativa (p<0,05) para os demais. O controle do estresse (3,99±0,67), a sociabilidade (3,83±0,83), e a estética (3,56±0,95) apresentaram escores motivacionais medianos, não diferindo estatisticamente entre si (p>0,05). A competitividade (2,42±0,98) foi o menor fator motivacional. Não foram encontradas diferenças significativas nas dimensões motivacionais entre os grupos de adesão e permanência. Conclusão: Os aspectos motivacionais com maior influência na prática da corrida de ruasão prazer e saúde, tanto para adesão, como para permanência na modalidade.
Objective: To analyze the motivational aspects associated with the practice of street running in recreational runners in southwestern Paraná. Methodology:This is a cross-sectional and quantitative study. 91 recreational runners of both genders, with a mean age of 38.4±10.2 years, participated in this research. A form of individual characteristics and the Inventory of Motivation for the Practice of Physical Activity (IMPRAF-126) were used as data collection instruments. The sample was dichotomized into an adherence group, with less than one year of practice, and a permanence group, with more than one year of practice. The Friedman test, the Bonferroni post hoc correction and the U-Mann-Whitney test were used to assess the differences between the motivational dimensions. Results: Health (4.60±0.41) and pleasure (4.41±0.53) were the strongest motivational aspects for the practice of street running, with a statistically significant difference (p<0. 05) for the others. Stress control (3.99±0.67), sociability (3.83±0.83), and aesthetics (3.56±0.95) showed median motivational scores, not statistically different from each other (p >0.05). Competitiveness (2.42±0.98) was the lowest motivational factor. No significant differences were found in the motivational dimensions between the adherence and permanence groups. Conclusion: The motivational aspects with the greatest influence on the practice of street running are pleasure and health, both for adherence and for staying in the modality.

Cluster sets (CS) are effective in maintaining performance and reducing perceived effort compared to traditional sets (TRD). However, little is known about these effects on adolescent athletes. The purpose of this study was to compare the effect of CS on the performance of mechanical and perceptual variables in young athletes. Eleven subjects [4 boys (age = 15.5 ± 0.8 years; body mass = 54.3 ± 7.0 kg; body height = 1.67 ± 0.04 m; Back Squat 1RM/body mass: 1.62 ± 0.19 kg; years from peak height velocity [PHV]: 0.94 ± 0.50) and 7 girls (age = 17.2 ± 1.4 years; body mass = 54.7 ± 6.3 kg; body height = 1.63 ± 0.08 m; Back Squat 1RM/body mass: 1.22 ± 0.16 kg; years from PHV: 3.33 ± 1.00)] participated in a randomized crossover design with one traditional (TRD: 3 × 8, no intra-set and 225 s interest rest) and two clusters (CS1: 3 × 2 × 4, one 30 s intra-set and 180 s inter-set rest; and CS2: 3 × 4 × 2, three 30 s intra-set and 90 s inter-set rest) protocols. The subjects were assessed for a Back Squat 1RM for the first meet, then performed the three protocols on three different days, with at least 48 h between them. During experimental sessions, a back squat exercise was performed, and mean propulsive velocity (MPV), power (MPP), and force (MPF) were collected to analyze performance between protocols, together with measures of countermovement jump (CMJ) and perceptual responses through Rating of Perceived Exertion for each set (RPE-Set) and the overall session (S-RPE), and Muscle Soreness (DOMS). The results showed that velocity and power decline (MVD and MPD) were favorable for CS2 (MVD: -5.61 ± 14.84%; MPD: -5.63 ± 14.91%) against TRD (MVD: -21.10 ± 11.88%; MPD: -20.98 ± 11.85%) (p < 0.01) and CS1 (MVD: -21.44 ± 12.13%; MPD: -21.50 ± 12.20%) (p < 0.05). For RPE-Set, the scores were smaller for CS2 (RPE8: 3.23 ± 0.61; RPE16: 4.32 ± 1.42; RPE24: 4.46 ± 1.51) compared to TRD (RPE8: 4.73 ± 1.33; RPE16: 5.46 ± 1.62; RPE24: 6.23 ± 1.97) (p = 0.008), as well as for Session RPE (CS2: 4.32 ± 1.59; TRD: 5.68 ± 1.75) (p = 0.015). There were no changes for jump height (CMJ: p = 0.985), and the difference between time points in CMJ (ΔCMJ: p = 0.213) and muscle soreness (DOMS: p = 0.437) were identified. Our findings suggest that using CS with a greater number of intra-set rests is more efficient even with the total rest interval equalized, presenting lower decreases in mechanical performance and lower perceptual effort responses.

ABSTRACT In order to carry out the process of validation and reproducibility of the Protocol for the Assessment of Individual Tactical Behavior of Soccer athletes (PADTI), a study was carried out divided into three stages: I) preparation of the PADTI; II) logical, content and construct validation and; III) reproducibility. The PADTI was developed based on the 8 fundamental tactical principles of soccer, which were inserted in a Microsoft Excel® spreadsheet, used to collect, store and process the tactical actions of soccer players during the game. The PADTI validity process was performed by 8 professionals, using a spreadsheet to account for items using a Likert scale (5 points). Reproducibility was carried out in two moments with an interval of 15 days, using as a sample the tactical behaviors of the athletes of the Brazilian team, during a soccer match of the 2018 world cup. validity (IV) of 90%. There were no significant differences between the responses of the evaluators (χ² = 12.199; p = 0.094). The intraclass correlation (ICC) values were greater than 0.814 (CI: 95%: 0.251 - 0.954; p <0.001) and Cronbach's Alpha values were greater than α = 0.814. The results indicated that the PADTI is a valid and useful methodology for assessing the tactical performance of soccer players in a game situation.
RESUMO Com o objetivo de realizar o processo de validação e reprodutibilidade do Protocolo de Avaliação do Comportamento Tático Individual de atletas de Futebol (PADTI), foi realizado um estudo dividido em três etapas: I) elaboração do PADTI; II) validação lógica, de conteúdo e constructo e; III) reprodutibilidade. O PADTI foi elaborado com base nos 8 princípios táticos fundamentais do futebol, os quais foram inseridos em uma planilha do programa Microsoft Excel®, utilizada para coletar, armazenar e processar as ações táticas dos atletas de futebol durante o jogo. O processo de validade do PADTI, foi realizado por 8 profissionais, por meio de uma planilha para contabilizar os itens utilizando-se de uma escala likert (5 pontos). A reprodutibilidade foi realizada em dois momentos com intervalo de 15 dias, utilizando como amostra os comportamentos táticos dos atletas da seleção brasileira, durante uma partida de futebol da copa do mundo de 2018. O PADTI foi aprovado pela maioria dos avaliadores especialistas, com índice de validade (IV) de 90%. Não foram observadas diferenças significantes entre as repostas dos avaliadores (χ²=12,199; p = 0,094). Os valores de correlação intraclasse (ICC) foram superiores a 0,814 (IC: 95%: 0,251 - 0,954; p< 0,001) e os valores de Alpha de Cronbach foram superiores a α= 0,814. Os resultados indicaram que o PADTI é uma metodologia válida e útil para avaliação do desempenho tático de atletas de futebol em situação de jogo.

O isolamento social foi utilizado como estratégia de redução da disseminação do vírus responsável pela pandemia da COVID-19, influenciando diversos aspectos da vida de toda a população mundial. Objetivo: Ao considerar a importância da qualidade de vida para vida das pessoas, o presente estudo buscou analisar a qualidade de vida de estudantes universitários de um curso de Educação Física de uma universidade pública da região sul brasileira durante a pandemia da COVID-19. Metodologia: Trata-se de um estudo transversal e quantitativo, desenvolvido com 166 estudantes universitários dos cursos de bacharelado e licenciatura, de ambos os sexos, e com idade média de 23,8±4,96 anos. Para a coleta de dados, que ocorreu em dezembro de 2020, utilizou-se o WHOQOL-bref em sua versão web. Os participantes receberam os links do instrumento para participação no estudo. O teste U-Mann-Whitney foi utilizado para analisar as diferenças estatísticas entre os sexos e cursos investigados. Resultados: Os maiores escores de qualidade de vida foram apresentados pelo domínio físico (71,3±13,8) e os menores pelo domínio psicológico (61,0±15,0). Não foram identificadas diferenças estatisticamente significativas (p>0,05) nos domínios de qualidade de vida entre os sexos e cursos investigados. Conclusão: Embora os estudantes tenham apresentado níveis moderados de qualidade de vida (escores próximos a 60 pontos), os índices são cerca de 10% menores que nos estudos desenvolvidos no período anterior à pandemia, o que evidencia que o período de pandemia pode ter impactado negativamente na percepção de qualidade de vida dos estudantes investigados.
Social isolation was used as a strategy to reduce the spread of the virus responsible for the COVID-19 pandemic, influencing different aspects of the life of the entire world population. Purpose: When considering the importance of quality of life for people's lives, this study sought to analyze the quality of life of university students attending a physical education course at a public university in southern Brazil during the COVID-19 pandemic. Materials and Methods: This is a cross-sectional and quantitative study, developed with 166 university students from bachelor's and licentiate's courses, of both genders, with a mean age of 23.8±4.96 years. For data collection, which took place in December 2020, the WHOQOL-bref in its web version was used. Participants received the instrument's links to participate in the study. The U-Mann-Whitney test was used to analyze the statistical differences between the sexes and investigated courses. Results: The highest quality of life scores were presented by the physical domain (71.3±13.8) and the lowest by the psychological domain (61.0±15.0). There were no statistically significant differences (p>0.05) in the quality of life domains between genders and investigated courses.Conclusion: Although students had moderate levels of quality of life (scores close to 60 points), the rates are about 10% lower than in studies carried out in the period prior to the pandemic, which shows that the pandemic period may have negatively impacted the perception of the quality of life of the investigated students.
