This study sought to examine the variations of internal and external load measures in soccer players when performing different types of 4 vs. 4 small-sided games (SSGs). Ten U-23 professional and sub-elite soccer players, eight outfield players (age: 20.1 ± 1.5 years old; height: 1.83 ± 0.04 m; total body mass: 76.1 ± 3.6 kg) and two goalkeepers (GK) (age: 20.5 ± 2.1 years old; height: 1.91 ± 0.04 m; total body mass: 77.0 ± 1.4 kg) participated in the study. Five SSGs were performed with 3 min duration and 3 min rest interval. SSG1, SSG2 and SSG4 aimed for ball possession play, while in SSG3 and SSG5, two GK were added, defending regular-size goals. The pitch size changed from SSG1 (16 × 24 m) to SSG2 and SSG3 (both 20 × 30 m) and SSG4 and SSG5 (both 24 × 36 m). All players were monitored using WIMU Pro device during the tasks. Anova One-Way and the post hoc Tukey honestly significant difference were used for analysis of statistically significant differences (p< 0.05) and effect sizes were determined by calculating partial eta-squared. The framework was associated with relevant but steady state internal load fatigue and induce a considerable external load stimulus. GK participation in SSGs should be carefully considered as it seems to have a greater impact on physical load measures when compared to the pitch size manipulation.

This study sought to evaluate the training load in different age category soccer players associated with distinct pitch size small-sided games (SSGs). Twenty-four soccer players (eight in each age category: U-12, U-15, and U-23) performed three consecutive 4 vs. 4 ball possession SSGs (SSG1: 16 × 24 m; SSG2: 20 × 30 m; and SSG3: 24 × 36 m) all with 3 min duration and 3 min rest. Subjects carried ultra-wideband-based position-tracking system devices (WIMU PRO, RealTrack System). Total distance covered increased from SSG1 to SSG3 in all age categories and predominantly in running speeds below 12 km·h−1. Moreover, distance covered in 12–18 km·h−1 running speed was different in all performed SSGs and age categories. Residual or null values were observed at 18–21 km·h−1 or above running speed, namely in U-12, the only age category where metabolic power and high metabolic load distance differences occurred throughout the performed SSGs. Edwards’ TRIMP differences between age categories was only observed in SSG2 (U-12 < U-15). The design of SSGs must consider that the training load of the players differs according to their age category and metabolic assessment should be considered in parallel to external load evaluation in SSGs. Wearable technology represents a fundamental support in soccer.

We aimed to compare the velocity, physiological responses, and stroke mechanics between the lactate parameters determined in an incremental step test (IST) and maximal lactate steady state (MLSS). Fourteen well-trained male swimmers (16.8 ± 2.8 years) were timed for 400 m and 200 m (T200). Afterwards, a 7 × 200-m front-crawl IST was performed. Swimming velocity, heart rate (HR), blood lactate concentration (BLC), stroke mechanics, and rate of perceived exertion (RPE) were measured throughout the IST and in the 30-min continuous test (CT) bouts for MLSS determination. Swimming velocities at lactate threshold determined with log-log methodology (1.34 ± 0.06 m∙s−1) and Dmax methodology (1.40 ± 0.06 m∙s−1); and also, the velocity at BLC of 4 mmol∙L−1 (1.36 ± 0.07) were not significantly different from MLSSv, however, Bland–Altman analysis showed wide limits of agreement and the concordance correlation coefficient showed poor strength of agreement between the aforementioned parameters which precludes their interchangeable use. Stroke mechanics, HR, RPE, and BLC in MLSSv were not significantly different from the fourth repetition of IST (85% of T200), which by itself can provide useful support to daily practice of well-trained swimmers. Nevertheless, the determination of MLSSv, based on a CT, remains more accurate for exercise evaluation and prescription.

Our study aimed to verify whether the manipulation of task constraints has different effects according to age group. Another objective was to verify the physiological and physical responses in the different formats of small-sided games (SSG). Each team in the SSGs was composed of 4 players (4x4). The participants in the research are young football players U-12 (n=8) and U-15 (n=8), affiliated with a club certified as a training entity, and competed in the regional football championship of 7 and 9 players and the national championship of Portugal, respectively. The internal and external load data were collected in 5 formats of SSGs with three field size and in 2 used goalkeepers. We used the WIMU PROTM inertial device for data collection. The registration of the internal charge, using heart rate (HR), was performed with the use by the players of Garmin bands, which send the data to WIMU PROTM devices, through of Ant+ technology. The variance analysis (ANOVA) was used to verify the differences between SSGs and the effect size was determined by calculating partial eta-square). Comparisons between the two age groups were evaluated using standardized differences with combined variance (Cohen’s d). The results show that the manipulation of the playing areas and the use of goalkeepers promoted different effects in the two age groups in terms of distance, explosive distance, accelerations/decelerations and maximum sprint. As for the comparison between SSGs we found differences in the level of external load (distance, accelerations/decelerations and maximum sprint). At the level of internal load, the effects were more evident with field areas above 100m2. We can conclude that the manipulation of the task conditions, playing area and goalkeeper, promote different physical and physiological responses, and the coach should consider this fact, as well as the effects promoted in the age groups.

This study aims to identify the expectationsof the coacheson the instruction and behavior of athletes. The second objective is to correlate the expectations of the coaches with the instruction behavior of coaches and with the behavior of athletes in competition.Aiming to achieve these purpose four coaches of youth soccer teams that competed in the national championships in Portugal was studied.We applied observation systems SAIC and SOCAC to encode behaviors of coach's instruction and the behavior of athletes in competition, respectively. To collect data on expectations,the coaches responded to the Questionnaire about Expectations of Instruction and Behavior of Athletes in Competition. The results show that there is short relation between the coach's expectations and what actually happens in competition regarding the instruction behavior and the behavior of athletes.

O presente estudo tem por objetivo detetar T-patterns de comportamento de instrução em treinadores de jovens na direção da equipa em competição, utilizando para o efeito o programa THEME 5.0. Para a realização da presente investigação recorreu-se à metodologia observacional. Foram filmados 8 jogos de futebol de 4 treinadores que dirigiam equipas de Juniores “B” e juniores “A” que competiam nos campeonatos nacionais de Portugal e codificados os seus comportamentos de instrução através do sistema de observação SAIC. Os resultados obtidos revelaram a existência de padrões temporais de comportamento de instrução, quer na análise feita aos treinadores individualmente, quer na análise feita no conjunto dos treinadores. Os T-patterns analisados demonstram que os treinadores procuram preferencialmente prescrever soluções táticas e psicológicas, direcionadas ao atleta, recorrendo à comunicação verbal, bem como avaliar positivamente a sua execução e comportamento. Durante as substituições os treinadores fornecem indicações com conteúdo tático e psicológico ao atleta que vai entrar, elogiam a prestação do jogador que saiu e emitem informação à equipa.
