Effects of the Number of Players and Game Type Constraints on Heart Rate, Rating of Perceived Exertion, and Technical Actions of Small-Sided Soccer Games

Abstract

The purpose of this study was to identify the variation of heart rate (HR), rating of perceived exertion (RPE), and technical actions between 2 soccer small-sided games (SSGs; 3 × 3 and 4 × 4) in 3 game type constraints (when playing only offense [OFF], playing only defense [DEF], and both situations [GAME]). Sixteen high-level young male players were analyzed (age 15.75 ± 0.45 years; height 172.4 ± 4.83 cm; body mass 64.5 ± 6.44 kg; HRmax199.1 ± 9.08 b·min(-1); and 8.06 ± 1.98 years of soccer practice). All tasks were performed in 4 periods of 4 minutes interspersed with 2 minutes of active recovery. The HR was measured continuously and then analyzed by the time spent into 4 training zones according to individual %HRmax (zone 1 <75%; zone 2 75-84.9%; zone 3 85-89.9%; and zone 4 ≥90%). Results identified that players were most frequently in zones 2 and 3. The 3 × 3 SSGs elicited higher HR and RPE and the most intense situation was GAME. Despite the known higher frequencies from technical actions in SSGs with fewer players, player effectiveness in 3 × 3 and 4 × 4 was identical. The use of GAME, OFF, and DEF game type constraints should be carefully planned. Using the 3 × 3 format seems more adequate when aiming for aerobic performance optimal effects; however, DEF situations should only be used to promote aerobic recovery effects. The inclusion of an additional player in SSGs had different interactions in game type constraints, and only GAME presented adequate intensity.

Match Analysis of U9 and U10 English Premier League Academy Soccer Players Using a Global Positioning System

“…Using 18 similar speed zones (based on senior player sprint performance), the English FA Premier 19 (Senior) League soccer players spent 6.4 and 2.6% of total match time in moderate speed 20 running and high speed running, respectively (4). These findings imply that the U9 and U10 21 elite soccer players may spend a lower proportion of match time in high intensity running 22 than top elite professional soccer players and this is possibly because of differences in the 23 area per player (1,5,27). Hence, for the U9 and U10 players to achieve a similar proportion 24 of time in each speed zone in comparison to the elite senior players, the pitch dimensions…”

Efectos de un programa de juegos reducidos en la percepción subjetiva del esfuerzo en una muestra de chicas adolescentes

“…Los resultados indicaron que no hubo diferencias significativas en los efectos principales de la variables pre-post y grupo (p > .05), aunque sí en los efectos de la interacción para las medidas posteriores al ejercicio 2 (F [1,40] = 5.15; p < .05; η2 = .11; 1-β = .60) y el ejercicio 3 (F [1,40] = 6.78; p < .05; η2 = .14; 1-β = .72). Además, hubo indicios de significación en los valores posteriores al ejercicio 1 (F [1,40] = 3.95; p = .053; η2 = .09; 1-β = .49) y 5 minutos después del ejercicio 3 (F [1,40] = 3.60; p = .065; η2 = .08; 1-β = .46). Además, la prueba de Levene indicó que no hubo problemas de homogeneidad de varianza cuyos valores oscilaron entre .01 y 1.53, siendo no significativa en todos los casos (p > .05).…”

“…Los resultados de los aná-lisis de la varianza (ANOVA) factorial indican que no hubo diferencias significativas en el efecto principal grupo, aunque sí para la variable pre-post en IPJ para balonmano (F [1,40] Por otro lado, las comparaciones simples (Bonferroni) indicaron que no hubo diferencias significativas entre los grupos antes de la intervención. Sin embargo, tras ella, sí existieron en todos los factores salvo en IPJ para fútbol-sala.…”

Demandas Físicas São Influenciadas Pelo Estatuto Posicional Em Pequenos Jogos De Futebol?

“…Em relação aos pequenos jogos, estudos frequentemente investigam respostas técnicas 13 , táticas 14 , físicas -associadas ao perfil motor -e fisiológicas 15 a partir de alterações nas configurações, i.e. tamanho do campo 13 , número de jogadores 13 , limitação de toques na bola 16 e superioridade numérica 17 .…”
