- Contemporary practices of portuguese and brazilian soccercoaches in designing and applying small-sided gamesPublication . Clemente, Filipe; Afonso, José; Silva, Rui Miguel; Aquino, Rodrigo; Vieira, Luiz Palucci; Santos, Fernando; Teoldo, Israel; Oliveira, Rafael; Praça, Gibson; Sarmento, HugoThis descriptive study aimed to investigate the current practices of Portuguese and Brazilian soccer coaches in the design and implementation of small-sided games (SSGs) in soccer. A total of 187 male coaches participated in the online survey, consisting of 82 Portuguese and 105 Brazilian individuals. These coaches held various positions within the technical staff, with 63 serving as head coaches, 38 as assistant coaches, 38 as physical trainers, and 48 in other roles related to the technical staff. Additionally, the participants represented both youth (n = 102) and adult competitive levels (n = 59), along with some who were not currently associated with a specific group. The survey consisted of 32 questions divided into three main sections: (i) the timing of SSG application, (ii) the methods used for applying SSGs, and (iii) the reasons for applying SSGs. The Chi-square test revealed a statistically significant association between nationality and the frequency of SSGs used in training sessions during the pre-season (p = 0.039) and in-season (p < 0.001). Moreover, significant association between nationality and the time allocated to employing SSGs for targeting aerobic training (p < 0.001) was found. There was a significant association between nationality and the weekly frequency of SSGs use for targeting sprint training (p = 0.019). The Chi-square test identified significant associations between nationality and the use of SSGs for targeting technical training (p = 0.002), as well as for tactical training (p = 0.002). In summary, this study underscores that SSGs are primarily employed to enhance aerobic fitness, change of direction, technical skills, and tactical behaviors. Coaches generally favor employing SSGs two to three times a week, with typical sessions lasting between 16 to 30 minutes. Notably, the major discrepancies between nationalities lie in the importance assigned to the use of SSGs. However, in practice, the formats and objectives for implementing SSGs remain relatively similar.
- Editorial: Optimizing athletic recovery: the effects of recovery strategies and sleep on sports performancePublication . Silva, Rui; González-Fernández, Francisco Tomás; Oliveira, Rafael; Aquino, RodrigoIn contemporary sport, recovery has emerged as a central component of the training and competitive process. It is no longer regarded simply as the time that follows exercise or competition, but rather as a complex and multidimensional process that supportsphysiological restoration, psychological readiness, adaptation to training, and the preservation of performance over time. As the physical and mental demands placed on athletes continue to increase, the capacity to recover effectively between sessions and competitions has become a matter of considerable importance for coaches, practitioners, and researchers alike. Growing interest in sleep, well-being, and recovery related interventions reflects a broader recognition that successful performance depends not only on the quality of training but also on the quality of restoration that follows it.
- Relationships between training load, peak height velocity, muscle soreness and fatigue status in elite-level young soccer players: a competition season studyPublication . Nobari, Hadi; Eken, Özgür; Kamiş, Okan; Oliveira, Rafael; González, Pablo Prieto; Aquino, RodrigoBackground This study aimed to compare training load parameters, delayed onset muscle soreness (DOMS), and fatigue status between season periods (1st and 2nd halves) in U14 soccer players and to analyze the relationships between training load parameters based on season periods (1st and 2nd halves) with peak height velocity (PHV), DOMS, and fatigue status in under-14 (U14) young elite soccer players. Additionally, it was intended to analyze if fatigue, DOMS and PHV could explain training load parameters across the season. Methods Twenty U14 players that competed in the national league participated in this study. The players were monitored during the whole season (26 weeks), and evaluations were carried out at the end of the in-season. Anthro pometric and body composition parameters and the maturity ofset of each player were utilized to compute each player’s age at PHV. Players reported their levels of DOMS and fatigue status using Hooper index questionnaires. The internal load was monitored using the rating of perceived exertion (RPE). Acute weekly internal load (AW), chronic weekly internal load (CW), acute: chronic workload ratio (ACWR), training monotony (TM), and training strain (TS) were also obtained. Results The main results showed that TM was higher in the 2nd half, while CW, AW and DOMS were higher in the 1st half of the season. Moreover, the main correlations showed a positive correlation between PHV and TS (2nd half of the season) and between fatigue and TM (1st half of the season). Conclusion In conclusion, variations in well-being status and PHV cannot explain the variations in internal training loads in elite U14 soccer players. In addition, internal training load indices during the frst half of the competitive sea son can promote a fundamental base for progression loads during the second period of the competitive seaso
- A systematic review of the criterion validity and reliability of technical and tactical field-based tests in soccerPublication . Clemente, Filipe Manuel; Praça, Gibson; Oliveira, Rafael; Aquino, Rodrigo; Araújo, Rui; Silva, Rui; Sarmento, Hugo; Afonso, JoséBackground: Field-based tests are important since they can guarantee ecological validity. Although most such tests are designed to assess physical fitness, tactical and technical dimensions are also determinants in a full battery of tests. Objectives: This systematic review aimed to (a) summarize the criterion validity and reliability of technical and tactical field-based tests applied in soccer and (b) list valid and reliable technical and tactical field-based tests. Methods: A systematic review of EBSCO, PubMed, Scielo, SPORTDiscus, and Web of Science databases was performed according to PRISMA guidelines. The eligibility criteria included (i) population (soccer players from any age group, com petitive level, or sex); (ii) exposure (exposure to technical and/or tactical field-based tests covering individual technical skills, tactical behaviours, tactical knowledge, and decision-making in the field); (iii) comparator (a laboratory test and/ or a criterion field-based test); (iv) outcome (measures of reliability); and (v) no restrictions concerning study design. The synthesis of results focused on the outcomes considered in the eligibility criteria. Results: A total of 5008 titles were identified, of which 21 met the eligibility criteria. Eight studies’ analyses centred on tactical tests. Of those, six studies tested the same instrument (FUT-SAT), one study examined divergent thought, and one study used a soccer-specific skills test Among the 10 included studies involving technical tests, only two repeated the same test (the Loughborough Soccer Passing Test). Three studies included tests concurring with physical ones. According to the main findings, the eight studies that used tactical tests revealed that the outcomes obtained from the tests and observers were reliable. The 10 studies that used technical tests, as well as the three concurrent studies, revealed similarly high reliability. Of the eight studies that used tactical tests, seven involved youth participants. Furthermore, three of the 10 studies that conducted technical tests were done on adults. Of the concurrent tests, three involved youth athletes. Only one study including a tactical analysis presented values for validity, while three others provided information about validity. The four studies provided information about test validity. Conclusions: Overall, the selected technical and tactical tests, most of which were carried out on youth players, revealed their validity and reliability. Although most studies focused on reliability (which was confirmed regardless of the test included), criterion validity was also observed in the few studies that analysed such factors. Thus, the tests cur rently proposed for assessing technical and tactical behaviours possess acceptable criterion validity and reliability.
- Variability of internal and external loads and technical/tactical outcomes during small-sided soccer games: a systematic review.Publication . Clemente, Filipe Manuel; Aquino, Rodrigo; Praça, Gibson; Rico-González, Markel; Oliveira, Rafael; Silva, Ana Filipa; Sarmento, Hugo; Afonso, JoséSmall-sided games (SSGs) are widely used in soccer training. However, some of the typical outcomes related to human responses during these games (namely internal and external load) may vary between sessions for similar practice conditions. Thus, the study of intra- and inter-bout variability in response to SSGs is progressively growing. This systematic review aimed to (1) identify studies that have examined the intraand inter-session bouts’ variability levels regarding the internal and external load and technical/tactical outcomes during SSGs and (2) summarize the main evidence. A systematic review of PubMed, SPORTDiscus, Cochrane, and Web of Science databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From the 486 studies initially identified, 24 were fully reviewed, and their outcome measures were extracted and analyzed. Sixteen studies analyzed internal load, 13 studies analyzed external load variables, six studies analyzed technical execution, and two studies analyzed tactical behavior. All studies included SSGs with a range number of players between 2 to 14 (1 vs. 1 to 7 vs. 7 SSGs). Internal load and low-speed external load variables presented a low variability, while high variations were reported regarding the technical execution and high-speed external loads.
