Running Speeds at Ventilatory Threshold and Maximal Oxygen Consumption Discriminate Futsal Competitive Level

Abstract

We tested the hypothesis that maximal oxygen uptake and ventilatory threshold (VT), and their respective speeds (S(VO2max) and S(VT)) could discriminate the competitive level of futsal players. The outfield players of a high-level Brazilian professional futsal team (N = 9; age 22.6 ± 4.2 years; body mass 70.6 ± 6.4 kg; height 174.3 ± 6.0 cm), and a semiprofessional team (N = 11; age 17.2 ± 0.8 years; body mass 70.4 ± 6.5 kg; height 175.0 ± 4.0 cm), volunteered for participation in this study. Subsequently, they were evaluated during an incremental treadmill test for the determination of cardiorespiratory variables, S(VO2max), and S(VT). Both teams exhibited a similar body mass and VO2max (p = 0.542 and p = 0.427), whereas the S(VO2max) and the S(VT) were significantly higher in the professional team (p = 0.001 and p = 0.030, respectively). Additionally, the professional team exhibited both lower HR at VT (p = 0.046) and HRmax (p = 0.002). However, the %HRmax at VT did not differ between groups (p = 0.912). These results remained similar after adjusting for the age differences between groups (p = 0.106). It was concluded that both S(VO2max) and S(VT) were sensitive for detecting differences in the competitive level of futsal players, whereas VO2max and VT were not.

Relação entre variabilidade da frequência cardíaca e aumento no desempenho físico em jogadores de futebol

“…Essa limitação se deve ao fato de que a pesquisa realizada em modalidades coletivas se restringe ao número de atletas disponível no elenco da equipe avaliada a qual também está sujeita a perdas amostrais pelos seguintes fatores: os goleiros são retirados das análises, atletas que se lesionam e não terminam as avaliações, que são transferidos e que se apresentam após o início da pesquisa. Entretanto, o tamanho amostral do presente estudo está de acordo com diversos estudos que têm investigado esportes coletivos [22][23][24] . Em que pesem algumas limitações do presente estudo, novas informações sobre a relação entre o sistema nervoso autônomo e desempenho foram produzidas.…”

Shuttle-Run Interval Training with More Directional Changes Induces Superior Gains in Shuttle Sprint Performance in Female Professional Futsal Players

“…owing to these high demands and the accumulation of fatigue during matches and training sessions, coaches and technical staff need to plan activities that allow an integral development of the player's physical and physiological traits during short periods of time (4-6 weeks), such as the preseason phases [6,7]. In addition to aerobic fitness features [7,8], in view of the high neuromuscular demands in modern futsal [9], strength and conditioning specialists should also properly optimize the athletes' speed and power capacities [10]. From a practical perspective, with the consideration of the 'interference phenomenon,' commonly reported in team sports [11,12], it does not seem straightforward to improve neuromechanical capabilities throughout preseason phases, where futsal players are frequently exposed to high volumes (ca.…”

Quais ações técnico-táticas realizadas durante as partidas de futsal podem discriminar o resultado de vitória ou derrota?

“…Estes estudos têm revelado a importância de determinados atributos da aptidão física no nível de desempenho dos jogadores de futsal [6][7] . Apesar da relevância de se compreender o papel de atributos físicos no nível de desempenho competitivo no futsal, outros fatores devem ser considerados para o melhor entendimento da modalidade, considerando a natureza multifacetada do desempenho no esporte coletivo [8][9][10] .…”
