Effects of Exercise Duration and Number of Players in Heart Rate Responses and Technical Skills During Futsal Small-sided Games

Abstract

Abstract:In the design of training programs, it is common for coaches to modify task constraints to conduct the drill intensity at the targeted level. Sport specific drills with variations are constantly used in Futsal practices, however the knowledge about how these variations influence drill intensity and technical demands is very scarce. The purpose of this study was to measure the physiological and technical effects of both duration and variations in the numbers of players in futsal specific drills. Heart rates and technical skills of 8 semi-professional futsal players were recorded during four specific drills. The experimental protocol consisted in a half-court game with official rules, played in 4v4, 3v3 and 2v2, each during 4 minutes and 4v4 during 10 minutes. It was maintained an active break of 4 minutes between each repetition. The lowest %HRmax was observed in response to the 4v4 drill independent of the exercise duration. In players' number variation statistically significant differences were found in the percentage of time spent between 65-85%HRmax, in the number of successive contacts with the ball and number of dribbles. In exercise duration, statistically significant differences were found in percentage of time spent above 85%HRmax, in the number of successive contacts with the ball, number of dribbles and number of tackles. The decrease in the number of players and exercise duration resulted in intensity increases and more frequent individual tactical actions.

Manipulating Task Constraints in Small-Sided Soccer Games: Performance Analysis and Practical Implications

“…that normally occur in soccer matches [4,5]. Time procedures employed in previous researches concerning SSGs in soccer and futsal were also considered [4,6,[17][18][19]. The pitch size of the SSG was 40 x 30 meters (length x width), and it was similar to those used in previous researches, as the pitch ratio per player (150 m 2 ) [8,20].…”

Efeitos Do Treinamento Em Jogos Reduzidos Com Inferioridade Numérica No Futebol

“…Também foi utilizado um compasso científico da marca Cescorf® (Brasil), com precisão de leitura de 0,1 mm e pressão constante de 10G/mm 2 para analisar as dobras cutâneas e o percentual de gordura 14,15 . Para monitorar a frequência cardíaca média e máxima foram utilizados monitores cardíacos da marca Polar ElectroOy®, Vantage (Finland) [16][17][18] . A percepção subjetiva de esforço foi verificada por meio de uma adaptação da escala de Borg de esforço percebido, sugerida por Pasquarelli et al 9 , que indica a resposta subjetiva de cada indivíduo, numa escala de intensidade de esforço, após uma sessão de treinamento 19 .…”

“…O protocolo utilizado foi o de Pollock e Jackson 15 . Para análise das variáveis dependentes foram consideradas a frequência média e máxima, obtida por meio do monitor cardíaco, durante as sessões de treino de jogos reduzidos e coletivo [16][17][18] . A percepção de esforço 3,19 e a atenção concentrada foram avaliadas imediatamente após as sessões de treino 13 .…”

A Review of Anthropometrical, Physiological, Psychological and Training Parameters of Futsal

“…It is suggested to coaches to use small sided games to improve technical, tactical, and physiological characteristics throughout realistic conditions (Serrano, Shahidian, Sampaio, & Leite, 2013). When trainers increase field size and reduce players' number they enhance also the physiological demands of the players (Duarte, Batalha, Folgado, & Sampaio, 2009;Duarte, Sampaio, Batalha, Maçãs, & Abrantes, 2007). Sampaio and colleagues (2007) as well as Duarte and colleagues (2009) confirmed that changes on the field size, game time, and players' number affect the physiological demands of futsal training (Duarte et al, 2009;Sampaio, Macas, Abrantes, & Ibanez, 2007).…”

They compared heart rate and technical skills of futsal players after 10min 4vs4 games and 4min 3vs3 and 2vs2 games on the half with a 4min break between the repetitions.…”
