Abstract Aim: The purpose of this paper was to analyze the internal consistency of the Sport Motivation Scale-II (SMS-II) questionnaire based on three studies with sports practitioners in the Brazilian college context. Methods: All the three studies i) were carried out with students enrolled in higher education and engaged in sports training by their institution (n1 = 304; n2 = 441; n3 = 310); ii) used SMS-II as an instrument for data collection; iii) used the online procedure for data collection. The Confirmatory Factor Analysis was performed and Cronbach's Alpha (α), McDonald's Omega (Ω), and the correlation between items were used to assess internal consistency. Results: As potentialities, five dimensions of the SMS-II presented high values of internal reliability (α and Ω > 0.60). As a limitation, the dimension of introjected regulation showed low reliability (α and Ω < 0.40) in the three studies conducted by our group. The exclusion of item 16 enabled an increase in alpha, but without achieving satisfactory reliability in Study 1 (α = 0.46) and Study 2 (α = 0.31). In Study 3, the exclusion of item 7 improved the internal reliability of the dimension (α = 0.43) also without reaching satisfactory values of internal consistency. It was not possible to identify a problematic item, given that each item had a different influence in the three studies. Conclusion: We found good values of validity and internal consistency for the Brazilian version of the SMS-II. However, we suggest attention to the introjected regulation dimension when using the instrument in the Brazilian college context.

RESUMO A ansiedade pode influenciar significativamente o rendimento do atleta no jogo. O objetivo do trabalho foi analisar a ansiedade traço e estado referentes às situações competitivas e correlacionar com as variáveis de ansiedade e autoconfiança. Trinta e uma estudantes-atletas universitárias (21,61; desvio padrão= 2,72 anos) da modalidade de basquetebol responderam os questionários de caracterização da amostra, o Sport Competition Anxiety Test e o Competitive State Anxiety Inventory-2 em três momentos de coleta (basal; pré-jogo e; pós-jogo). Os resultados: a) não mostraram diferenças estatisticamente significativas nos três momentos analisados na ansiedade traço, com correlações estatisticamente significativas com ansiedade cognitiva e autoconfiança (r= 0,389 e - 0,414, respectivamente); b) na ansiedade estado somática, houve diferença estatisticamente significativa entre os níveis basais, pré-jogo e pós-jogo, com correlações estatisticamente significativas com ansiedade cognitiva (r= 0,313) e autoconfiança (r= - 0,511); c) na ansiedade estado cognitiva, houve diferença estatisticamente significativa entre os níveis basais, pré-jogo e pós-jogo, com correlações estatisticamente significativas com autoconfiança (r= 0,289). Esta pesquisa, que avaliou a ansiedade em situações competitivas, possibilita identificar suas variações ao longo do tempo para fornecer dados importantes para a comissão técnica, melhorando assim as estratégias de intervenção no desempenho de atletas do esporte universitário.

ABSTRACT Anxiety can significantly influence the athlete's performance in the game. The objective of this study was to analyze the trait anxiety and state anxiety related to the competitive situation and correlate it between anxiety and self-confidence variables. Thirty-three college basketball student-athletes (21.61; standard deviation= 2.72 years old) were evaluated using sample characterization questionnaires, Sport Competition Anxiety Test, and Competitive State Anxiety Inventory-2 in 3 collection moments (baseline, pre-game, and post-game). The results showed: a) no statistically significant difference in the three moments analyzed in the trait anxiety, with statistically significant correlations with cognitive Anxiety and self-confidence (r= 0.389 e 0. 414, respectively); b) in somatic Anxiety, there was a statistically significant difference between baseline, pre-game and post-game levels, with statistically significant correlations with cognitive Anxiety (r= 0.313) and self-confidence (r= - 0.511); c) in cognitive Anxiety, there was a statistically significant difference between baseline, pre-game and post-game levels, with significant correlations with self-confidence (r= 0.289). This research, which evaluated Anxiety in competitive situations, makes possible the identification of these variations over time in order to provide important data for the coaching staff, thus improving intervention strategies for the athlete's performance of college sport.

Abstract: The objective of this study was to compare the selection of plants bred by different pedigree methods using selection among, among and within and only within families. The haploid induction rate of 14 S0:1 and seven S2:3 families, all crossed with the single-cross hybrid GNZ9501, was evaluated. An experimental area of the Department of Biology of the Federal University of Lavras (UFLA), in Lavras, Minas Gerais, in the growing seasons 2012/2013 and 2014/2015, was used for the experiments. In each growing season, one experiment per was carried out, arranged in a complete randomized design, with one and two replications, respectively. Haploid induction was most effective in the families 2 and 6 in both growing seasons. Selection among and within families resulted in higher genetic gains for haploid induction. The results indicated a high genetic variability for haploid induction rate in plants within families.
