“…To design the SSGs, a number of variables have been studied such as: (a) the players’ area [9], (b) the size of the pitch [8,10], (c) the field orientation [11,12], (d) the number of players [5,13], (e) the type of defense, (man-to-man or zone) [14], (f) the work-rest ratio [10,15], (g) the specific objectives, ending or ball possession [16,17], (h) the modification of the game rules [18], (i) play with or without a goalkeeper [19], (j) the presence of wildcard players [20] and (k) the feedback of the coach [8,21], among others. All of these are modified with the aim of reproducing the specific demands of the game [10], as they are effective independently of age, sex, experience and competitive level [22,23].…”

The purposes of the present study are: (a) to characterize the external (eTL) and internal load (iTL) of official matches and small-sided games (SSGs) in relation to their objective, (b) to compare demands between SSG, and (c) to analyze the SSG requirements in relation to official matches during a one-month competition period. Twenty under-18 national-level soccer players were recorded using WIMUTM inertial devices (RealTrack Systems, Almeria, Spain) during four official matches and 12 training sessions where four SSGs with different objectives were performed: (SSG1) keeping the ball; (SSG2) keeping the ball and progressing; (SSG3) keeping the ball, progressing and ending in mini-goals; and (SSG4) keeping the ball, progressing and ending in an official goal with a goalkeeper. Statistical analysis included Kruskall-Wallis’ H and Mann-Whitney’s U with Cohen’s d effect size. The SSGs presented walking and jogging intensity movements (0.7–7 to 7–14 km/h), with a 5-to-8 %HIA (high intensity activity, >16 km/h), where low intensity accelerations, decelerations and impacts were predominant (1–2.5 m/s2; 5–7 G), and %HRMAX (maximum heart rate percentage) was between 70–90%. Only SSG4 presented similar demands to competition, finding differences between SSGs (p < 0.05; d = 1.40 − 0.36). In conclusion, the objective of the SSGs directly influenced the demands on the players in training sessions. For this reason, it is important to monitor demands for designing specific training sessions.

“…Along the same lines, Fanchini et al [13] observed that the PE was not affected by the duration of the bouts (i.e., 2, 4, or 6 min). However, Muñoz et al [17] showed higher respiratory PE scores for an SG played in an IIS of 75 m 2 than for the same SG format played in an IIS of 175 m 2 . By contrast, other studies have demonstrated that different SG formats can influence the physical responses of soccer players [6,8], although it seems that the players did not declare different subjective responses.…”

“…One must also determine their physical performance before and after the completion of the SG [7]. For example, one study [16] has shown that male college players had a lower sprint performance over distances of 5 m and 15 m (ES = 0.87 ± 0.58 and 0.89 ± 0.58, respectively) after a 4 vs. 4 format plus goalkeepers SG that lasted for three bouts of six minutes and was played on a pitch of size 48 × 30 m. In addition, Muñoz, Castillo, and Yanci [17] observed a loss of physical performance in the 5 m sprint after an SG played on a 31 × 19 m pitch that lasted for four bouts of three minutes with three minutes of rest, but no significant differences were found in sprint performance before and after the SG for other SG formats.…”

It is crucial to understand the fatigue associated with sided games (SGs) of soccer in the training context, in order to establish the appropriate intervals between training sessions. Thus, the aim of this study was to investigate the effects of different SGs on internal load, measured by the session rating of perceived exertion (sRPE), and on sprint performance. Ten outfield players (age: 14.5 ± 0.5 years, height: 169 ± 6 cm, body mass: 59.7 ± 6.4 kg) belonging to U15 age category participated in this study. The participants played four SG formats with modifications in the pitch size and in the bout duration, but with the same total duration for the SGs (SG1, SG2, SG3, and SG4). All the players performed a 10 and a 30 m sprint test before and after the SGs. The internal load was measured by the sRPE. The results showed no significant differences (p > 0.05) in the sRPE registered by the soccer players for the different SGs, but worse sprint performances over the 10 m (p < 0.05; ES: 0.74–1.38, large) and 30 m (p < 0.05; ES: 0.70–2.10, moderate to large) distances after completion of the SGs, except the 10 m sprint after SG2 and SG3 (p > 0.05; ES: 0.43–0.55, moderate). In addition, no correlation (p > 0.05) was reported between the sprint performances for the 10 and 30 m distances and the sRPE registered during the SGs. These results could be useful for technical staff wishing to design the playing area and bout duration of their training tasks effectively.

“…En la literatura científica no se han encontrado resultados coincidentes que permitan proporcionar una conclusión clara acerca de cómo afectan los distintos formatos de JRs en el rendimiento en el test de esprint. Mientras Rebelo et al (17) mostraron que los jugadores empleaban más tiempo en recorrer distancias de 5 y 15 m después de la realización de un JR disputado en un formato de 5vs5 (porteros incluidos) y en un EII de 140 m 2 , Muñoz et al (18), en un JR de similares características, no observaron tales diferencias en el rendimiento en distancias de 15 m. En cambio, nuestros resultados mostraron una pérdida (muy probable -extremadamente probable pequeñas -moderadas -grandes) de rendimiento en el esprint en 10 y 30 m después de la última repetición en los distintos JRs respecto a antes de su comienzo. Sin embargo, diferencias poco claras y probables pequeñas fueron observadas en el rendimiento de SH.…”

“…En este sentido, algunos autores han mostrado una pérdida de rendimiento en la capacidad de esprintar en 5 y 15 m en un JR disputado en una situación de 4 vs 4 (con porteros) (17). En cambio, Muñoz, Castillo y Yanci (18), en un JR de 5 vs 5 (con porteros) no observaron tales diferencias en distancias de 15 m. Así mismo, otras investigaciones han analizado el efecto de los JR en la capacidad de salto vertical obteniendo resultados totalmente contradictorios. Mientras algunos autores observaron un descenso en la capacidad de salto vertical tras la disputa de un JR (19), otros autores no constataron tales pérdidas (20).…”

El principal objetivo de este estudio fue analizar la influencia de diferentes formatos de juego reducido (JR) en la carga interna medida mediante el esfuerzo percibido (CI EP) declarado por los futbolistas, y en el rendimiento del salto horizontal (SH) y la capacidad de acelerar y esprintar. Diez futbolistas cadetes (sub-16) participaron en el estudio. Los jugadores disputaron 4 formatos de JR con modificaciones en el espacio de juego y en la duración de las repeticiones. Los participantes realizaron un esprint de 30 m y un SH antes y después de cada repetición y también declararon el EP. Los resultados mostraron una mayor CI EP. Además, se observó un empeoramiento del esprint en 10 y 30 m después de la última repetición. Este conocimiento podría ayudar a los cuerpos técnicos a establecer de manera más apropiada la duración total y de cada repetición de los JRs.
