  • A systematic review of the criterion validity and reliability of technical and tactical field-based tests in soccer
    Publication . Clemente, Filipe Manuel; Praça, Gibson; Oliveira, Rafael; Aquino, Rodrigo; Araújo, Rui; Silva, Rui; Sarmento, Hugo; Afonso, José
    Background: 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.

  • Selected vs. non-selected under-20 national futsal players: differences between physical performance and training intensity experienced in training camps
    Publication . Silva, Ana Filipa; González-Fernández, Francisco Tomás; Oliveira, Rafael; Clemente, Filipe Manuel; Bezerra, Pedro; Hung, Chin-Hwai; Chiu, Yi-Wen; Kuo, Cheng-Deng; Chen, Yung-Sheng
    The aim of this study was two-fold: (i) analyze the variations in the physical fitness of selected and non-selected under-20 male national futsal players; and (ii) analyze the variations in training intensity monitored during training camps. Thirty-three Taiwan under-20 national futsal players were monitored for training intensity during 18 training camps. They were divided into two groups: selected (n = 14) and non-selected (n = 17) players. The physical assessments included the following measures: body mass, distance covered at Yo-Yo intermittent recovery test Level 1, final velocity at 30-15 Intermittent Fitness Test (30-15 IFT), standing long jump, maximum heart rate (HR), and 1-min sit-up. The training intensity was monitored using the rate of perceived exertion (RPE), HR at different intensity zones, and locomotor demands measured at different speed thresholds. The results revealed that the selected players were significantly faster in the 15-m sprint with ball (p = 0.001) and 30-m sprint (p = 0.001). Additionally, the selected players presented significantly greater HRaverage and time spent above 90% maximum HR during the three-to-six-day training camps (p < 0.05) compared to the non-selected players. Interestingly, the NS demonstrated a greater number of sprints during the training camps (p = 0.001), while the selected players presented greater distance/minute and average speed (p = 0.001). A regression analysis showed that the distance/minute and average speed was a significant predictor of maximum HR in the selected players. As conclusions, the physical fitness outcomes are different between the selected and non-selected national futsal players. The selected players spent more time in high intensity HR demands in training sessions

  • Acute and chronic workload ratios of perceived exertion, global positioning system, and running-based variables between starters and non-starters: a male professional team study
    Publication . Nobari, Hadi; Alijanpour, Nader; Martins, Alexandre Duarte; Oliveira, Rafael
    The study aim was 2-fold (i) to describe and compare the in-season variations of acute: chronic workload ratio (ACWR) coupled, ACWR uncoupled, and exponentially weighted moving average (EWMA) through session-rated perceived exertion (s-RPE), total distance (TD), high-speed running distance (HSRD), and sprint distance across different periods of a professional soccer season (early, mid, and end-season) between starters and non-starters; (ii) to analyze the relationship the aforementioned measures across different periods of the season for starters and non-starters. Twenty elite soccer players (mean±SD age, 29.4±4.4 y; height, 1.8±0.1m; and body mass, 74.8±2.3kg). They were divided into starter and non-starter groups and were evaluated for 20weeks. ACWR had general changes throughout the season. At the beginning and end of the mid-season, the highest ACWR was observed in three parameters: s-RPE, TD, and HSRD. ACWR and EWMA through sprint distance were higher at the beginning of the early-season than at any other time of the season. The ACWR coupled of s-RPE shows a significant higher value for non-starters than starters (p=0.015; g=−1.01 [−1.98, −0.09]) and the ACWR coupled of TD shows a significant higher value for starters than non-starters in early-season (p<0.01; g=3.01 [1.78, 4.46]) and shows a significant higher value for non-starters than starters in mid-season (p<0.01; g=−2.52 [−3.83, −1.39]), and end-season (p<0.01; g=−2.57 [−3.89, −1.43]). While the EWMA of TD shows a significant higher value for starters than non-starters in early season (p<0.01; g=2.25 [1.17, 3.49]) and mid-season (p<0.01; g=2.42 [1.31, 3.71]), and shows a significant higher value for non-starters than starters in end-season (p<0.01; g=−2.23 [−3.47, −1.16]). Additionally, we found some correlations between external and internal load measures during three periods of the in-season. The study’s main finding was that the indexes of ACWR and EWMA were useful to detect differences between period and between playing status with the exception for the sprint variable. In addition, the necessary work for non-starter players’ improvement is not done during training, and these players lose their readiness as the season progresses. Consequently, these players perform poorly during the match. Therefore, coaches and their staff should consider devising new activities to keep non-starter players physically fit. This deficit must be accounted for in training because they compete in fewer matches and have less burden than starters.

  • Sleep quality and training intensity in soccer players: exploring weekly variations and relationships
    Publication . Silva, Ana Filipa; Oliveira, Rafael; Akyildiz, Zeki; Yıldız, Mehmet; Ocak, Yücel; Günay, Mehmet; Sarmento, Hugo; Marques, Adilson; Badicu, Georgian; Clemente, Filipe Manuel
    The aim of this study was twofold: it (i) analyzed the weekly variations of sleep quality and training intensity of youth soccer players and (ii) analyzed the relationships between sleep quality and training intensity. This study followed an observational design. Twenty men youth players (age: 18.81 ± 0.41 years) were monitored daily over two weeks for sleep quality and training intensity. Sleep quality was measured daily using the 15-item consensus sleep diary. The training intensity was measured daily using the CR-10 Borg’s scale as a measure of rate of perceived exertion (RPE); a heart rate (HR) sensor was used to measure minimum, average and peak; a global positioning system (GPS) was used for measuring the total distance covered and distances covered at different speed thresholds. Repeated measures ANOVA was used to analyze the weekly variations of sleep quality and training intensity. The Pearson correlation test was executed to analyze the relationships between sleep quality and training intensity. Repeated measures ANOVA revealed significant within-week variations in sleep duration (hours) (p = 0.043), quality of sleep (p = 0.035), RPE (p = 0.007), session-RPE (p = 0.011), HRminimum (p = 0.027), HRpeak (p = 0.005), total distance (p < 0.001), pace (p < 0.002), distance covered at 3.00–6.99 km/h (p < 0.001), distance covered at 7.00–10.99 km/h (p < 0.001), distance covered at 11.00–14.99 km/h (p < 0.001), distance covered at 15.00–18.99 km/h (p < 0.001) and distance covered at >19.00 km/h (p < 0.001). Significant small correlations were found between sleep duration before training and session-RPE (r = 0.252), total distance (r = 0.205), distance covered at 3.00–6.99 km/h (r = 0.209) and distance covered at 7.00–10.99 km/h (r = 0.265). Significant small correlations were found between session-RPE and sleep duration after (r = 0.233), total distance and quality of sleep after (r = 0.198), distance at 3.00–6.99 km/h and quality of sleep after training (r = 0.220), distance covered at >19.00 km/h and quality of sleep after training (r = 0.286), session duration and rested feeling after training (r = 0.227), total distance and rested feeling after training (r = 0.202), distance covered at 11.00–14.99 km/h and rested feeling after training (r = 0.222) and distance covered at >19.00 km/h and rested feeling after training (r = 0.214). In conclusion, sleep duration was longer in the training sessions during the middle of the week; the training intensity was also greater (485.8 ± 56.8 A.U.). Moreover, sleep outcomes after training were slightly correlated with both physiological and locomotor demands

    O presente trabalho resulta da implementação e análise de uma visita de estu-do realizada à Resitejo – unidades de Triagem, Tratamento Mecânico e Bio-lógico e Aterro, localizada na Carregueira, no âmbito da Unidade Curricular de Pedagogia da Educação Ambiental do curso de Licenciatura em Educação Ambiental e Turismo de Natureza. A visita de estudo foi planeada conside-rando os seguintes momentos: pré-visita, visita e pós-visita. Cada grupo de estudante ficou responsável por fazer um levantamento prévio de informações sobre o local, criar um questionário no Google Forms sobre uma das unidades da Resitejo para ser respondido durante a visita através do telemóvel. Esta atividade teve por objetivos: construir conhecimentos sobre o funcionamento das unidades da Resitejo; compreender a importância da valorização de resí-duos e adquirir conhecimentos didáticos para conceber atividades de educação ambiental. Na fase de pré-visita, procedeu-se a uma pesquisa sobre os proces-sos de valorização de resíduos. Cada grupo ficou responsável pela elaboração de um questionário correspondente ao funcionamento de uma das unidades da Resitejo. As respostas dadas pelos participantes da visita (a própria turma) aos questionários permitem verificar conhecimentos ao nível: do tratamento dos RSU, do planeamento, organização e avaliação de uma visita de estudo; da utilização de suportes digitais como recurso para implementar atividades, de competências de divulgação dos resultados da atividade. Os conhecimentos construídos resultaram da pré-visita, durante a qual pesquisaram informações sobre o funcionamento das unidades da Resitejo, e do questionário construído, bem como da fase de visita em que as técnicas do local foram dando explica-ções que permitiram responder aos questionários. Este tipo de atividade é de grande relevância enquanto instrumento de apoio à ação do educador ambien-tal na disseminação de informação e como meio de sensibilização ao público-alvo e à população em geral.
