Item Influência dos saltos verticais na percepção da carga interna de treinamento no voleibol.(2017) Horta, Thiago Andrade Goulart; Bara Filho, Maurício Gattás; Miranda, Renato Melo; Coimbra, Danilo Reis; Werneck, Francisco ZacaronIntrodução: No voleibol, o salto vertical é considerado um elemento de extrema importância no treinamento, pois é necessário durante as ações de levantamento, saque, bloqueio e ataque, condicionando a obtenção de importantes vantagens nas ações ofensivas (ataque) e defensivas (bloqueio), elementos fundamentais para a conquista dos pontos no jogo. 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 vertical de ataque exerce maior influência no valor final de PSE apontado pelos atletas nas sessões de treinamento.Item Is the internal training load different between starters and nonstarters volleyball players submitted to the same external load training? : a case study.(2017) Horta, Thiago Andrade Goulart; Coimbra, Danilo Reis; Miranda, Renato Melo; Werneck, Francisco Zacaron; Bara Filho, Maurício GattásThe same training stimulus can provide different physiological adaptations for athletes of the same team. Thus, the aim of this study was to analyze and compare the load training of starters and nonstarters players, athletes of a men’s volleyball team at different times of the season. The sample consisted of fifteen men’s volleyball superleague athletes who were divided into two groups of starters and nonstarters players. The training load of the ten weeks of the team’s preparation period for the main championship season in which no games were performed was selected for the study. The method of subjective perceived of effort (session-RPE) proposed by Foster et al. (2001) was used to quantify the training load. The group of starters players had higher total weekly training load (TWTL) and RPE values in the average of the ten weeks of training (p<0.05). Higher TWTL values for starters players in the preparatory and pre-competitive period compared to nonstarters players was also demonstrated (p<0.05). When different weeks were analyzed separately, weeks three and seven presented higher TWTL and RPE values for starters players compared with nonstarters players (p<0.05). The results presented in this study showed that starters players showed greater internal training load compared to nonstarters players.Item Perfil da carga de treinamento no voleibol de alto rendimento : um estudo de caso.(2019) Horta, Thiago Andrade Goulart; Bara Filho, Maurício Gattás; Coimbra, Danilo Reis; Werneck, Francisco Zacaron; Miranda, Renato MeloAnalisar o perfil da carga de treinamento (CT) durante uma temporada de voleibol. Participaram 12 atletas masculinos (26,9 ± 4,6 anos) de uma equipe profissional. Foram analisadas 20 semanas, divididas em Período Preparatório (PP), Período Competitivo I (PC-I) e Período Competitivo II (PC-II). O método da Percepção Subjetiva do Esforço da sessão (PSE-S) foi usado para calcular a CT, a Monotonia e o Strain, bem como para comparar as semanas com diferentes números de jogos e entre as cinco posições. A CT diária (CTD) foi significativamente maior no PP do que no PC-I e PC-II (625, 400 e 363 unidades arbitrárias [UA], respectivamente), bem como a Monotonia e o Strain. A CT Semanal Total (CTST) foi significativamente menor na semana com dois jogos do que na semana com um jogo ou sem jogo (377, 500 e 622 U.A., respectivamente). Na comparação por posição, os atletas da Ponta obtiveram a maior CT (515 UA). Em conclusão, as maiores CT foram no PP, sem jogo e em atletas da posição de Ponta.Item Training load, physical performance, biochemical markers, and psychological stress during a short preparatory period in Brazilian elite male volleyball players.(2019) Horta, Thiago Andrade Goulart; Bara Filho, Maurício Gattás; Coimbra, Danilo Reis; Miranda, Renato Melo; Werneck, Francisco ZacaronThe aim of this study was to assess the relationship between training load (TL) and physical performance, biochemical markers, and psychological stress during a short preparatory period (SPP) in Brazilian elite male volleyball players. Twelve volleyball players from a team competing in the Brazilian Men’s Volleyball Super League were enrolled (26.9 6 4.6 years). Countermovement jump (CMJ), creatine kinase (CK), testosterone (T), cortisol (Cr), T/Cr ratio, and Recovery and Stress Questionnaire for athletes (RESTQ-Sport) were collected at baseline, after second, fourth, and sixth week. Training load was quantified daily using the rating of perceived exertion. Differences were noted between total weekly training load (TWTL) (F3,33 = 50.907; p = 0.0001), CK (F3,33 = 16.157; p = 0.0001), and T (F3,33 = 3.283; p = 0.03). No differences were seen in CMJ (F3,33 = 1.821; p = 0.16), Cr (F3,33 = 2.409; p = 0.08), or T/Cr ratio (F3,33 = 1.527; p = 0.23). The RESTQ-Sport demonstrated differences between moments in social stress (F3,33 = 2.297; p = 0.04; h2 = 0.25), success (F3,33 = 4.350; p = 0.01; h2 = 0.19), general wellbeing (F3,33 = 4.465; p = 0.01; h2 = 0.36), and injury (F3,33 = 2.792; p = 0.05; h2 = 0.62). The results showed a significant correlations of small to moderate magnitude between TWTL and CK (r = 0.32; p = 0.05). In conclusion, a short PP in volleyball leads to increased TL, CK level, and psychological stress. Training load was related with the increase of CK, suggesting muscle damage without increased physical performance.
