Assim, pesquisadores da Psicologia do Esporte vêm tentando identificar quais os motivos levam as pessoas a praticarem essa modalidade. Uma das teorias mais aceitas para entender a motivação do indivíduo para o esporte e exercício é a Teoria da Autodeterminação (TAD). A TAD define a motivação em um continuum, do indivíduo mais autodeterminado (intrinsecamente motivado) até o menos autodeterminado (amotivado). Objetivo: Identificar e analisar a motivação de corredores de rua recreacionais com base na TAD. Método: O desenho do estudo possui uma abordagem quanti-qualitativa. Foi utilizado o questionário SMS-28BR e uma entrevista semiestruturada. A amostra consistiu de 51 corredores participantes do Ranking de Corrida de Rua de Juiz de Fora (MG). Resultados: Verificou-se a existência de diversos motivos atuando concomitantemente para a prática da modalidade, principalmente por...

(1995). It is based on the principles of self-determination theory. The present study translated the English version into Portuguese to access and validate it with Brazilian athletes using a sample of 419 athletes (127 women and 292 men) from ten sports. The Brazilian version of the scale showed satisfactory levels of internal consistency and temporal stability over a four-week period. The results of a confirmatory factor analysis partially supported the seven-factor structure. Finally, gender differences were found in all subscales. Taken together, these findings support the use of the Brazilian version of the scale for the assessment of motivation in sport.

J Strength Cond Res XX(X): 000-000, 2018-The objective of this study was to analyze the training load (TL) and recovery status (RS) of a volleyball team in different periods of the season. Fifteen male athletes participated in the study. Training load was quantified through the rate of perceived exertion of session. The total weekly TL of the preparatory period (PP), competitive period I (CPI), and competitive period II (CPII) was calculated. Total quality recovery was used to evaluate the initial and final RS. Training load was higher (p &amp;amp;amp;amp;lt; 0.05) in PP than in CPI and CPII. The final RS was lower (p &amp;amp;amp;amp;lt; 0.05) in PP than in CPI and CPII. There was a difference (p &amp;amp;amp;amp;lt; 0.05) between the initial and final RS in the analyzed periods. An inverse correlation (ρ: -0.62) was observed between the TL and the initial and final difference RS in PP. In conclusion, PP in volleyball presented the highest TL, related to a greater difference between the initial and final RS.

Methods: The sample comprised 667 Brazilian athletes: male (n = 467; 70%); female (n = 200; 30%) with mean age 25 ± 5 years and eight (± 5) years of experience in individual sports (n = 182; 27.3%) or team sports (n = 485; 72.7%). Results: For construct validity, the relational structure of the items that comprise the original version of ACSI-28 was analyzed using EFA. The Kaiser-Meyer-Olkin measure (KMO = .83) and the Bartlett sphericity test (p

Knowledge of these variables over volleyball seasons is still scarce. Objective To monitor and describe the training load and recovery status of volleyball players over a competitive season. Methods The sample consisted of 14 professional volleyball players. For the entire season, the training load was monitored daily by the SPE method during the session, and the recovery status was monitored by TQR and QBE on the first and last days of training for the week. Results There was a decrease in training load between Preparatory Period I and Competitive Period I (p = 0.03), followed by an increase in Preparatory Period II (p <0.001) and a new decrease in Competitive Periods II (p = 0.01 ) and III (p = 0.003). There was a significant reduction between Pre-TQR and QBE and Post-TQR and QBE in all mesocycles. In the Pre-TQR, there was a reduction between Preparatory Pe...

A recuperação foi quantificada pela Escala de TQR, a carga pela PSE da sessão e o bem-estar pela escala de QBE. Para comparar os valores da Carga de Treinamento Semanal Total, o delta da Qualidade Total de Recuperação (ΔTQR) e o delta da Qualidade de bem-estar (ΔQBE) foi aplicado o teste ANOVA para medidas repetidas. Não foram encontradas diferenças significativas ao comparar a carga de treinamento com a frequência de jogos semanais, porém o tamanho do efeito foi muito elevado quando se comparou a diferença entre um e dois jogos semanais, assim como de nenhum a dois jogos na semana. Houve diferença entre o ΔTQR entre as semanas sem jogos e com dois jogos assim como entre as semanas com um e dois jogos. Já o ΔQBE foi diferente para as semanas que não havia a realização de jogos e aquelas com jogos....

Objetivo: Analisar a influência do salto vertical na quantificação da carga de treinamento no voleibol por meio do método da percepção subjetiva do esforço (PSE) da sessão. Métodos: Participaram do estudo 15 atletas do sexo masculino de uma equipe de voleibol. Foi realizada a quantificação dos saltos e da PSE de 30 sessões de treinamento. Resultados: Na análise por posição, a PSE apresentou correlação positiva com o número de saltos e se mostrou mais forte nos opostos (r = 0,44; p = 0,001; n = 57), seguida pelos ponteiros (r = 0,34; p < 0,001; n = 109) e centrais (r = 0,18; p = 0,03; n = 141). Conclusão: Conclui-se que o salto ver...

Training load and recovery in volleyball during a competitive season. J Strength Cond Res XX(X): 000-000, 2018-The objective of this study was to analyze the training load (TL) and recovery status (RS) of a volleyball team in different periods of the season. Fifteen male athletes participated in the study. Training load was quantified through the rate of perceived exertion of session. The total weekly TL of the preparatory period (PP), competitive period I (CPI), and competitive period II (CPII) was calculated. Total quality recovery was used to evaluate the initial and final RS. Training load was higher (p &amp;amp;amp;amp;lt; 0.05) in PP than in CPI and CPII. The final RS was lower (p &amp;amp;amp;amp;lt; 0.05) in PP than in CPI and CPII. There was a difference (p &amp;amp;amp;amp;lt; 0.05) between the initial and final RS in the analyzed periods. An inverse correlation (ρ: -0.62) was observed between the TL and the initial and final difference RS in PP. In conclusion, PP in volleyball presented the highest TL, related to a greater difference between the initial and final RS.
