- Analyzing the effects of competitive fatigue on body composition and functional capacities of youth elite handball playersPublication . Martins, Francisco; França, Cíntia; Sarmento, Hugo; Przednowek, Krzysztof; Śliż, Maciej; Campos, Pedro; Lopes, Helder; Marques, Adilson; Gouveia, Élvio Rúbio; Pestana Martins, João Francisco; França, Cíntia; Sarmento, Hugo; Pereira Campos, Pedro Filipe; Lopes, Helder; Marques, Adilson; Gouveia, Élvio RúbioHandball demands intense movements like rapid direction changes and physical contact. Consecutive competitions expose player fatigue and weaknesses due to the sport’s exhaustive nature. Therefore, the aims of this study are twofold: (i) to investigate the impact of competitive fatigue on the body composition of youth elite handball players, and (ii) to analyze the impact of concentrated competition on their functional capacity performance. Seventeen young male handball players (age: 16.2 years, height; 177.8 cm, body mass: 73.0 kg) were assessed twenty-four hours before (TM1) and after the competitive period (TM2) in body composition, static strength, lower- and upper-body explosive strength, speed, agility, balance, and flexibility indicators. A Wilcoxon Signed Rank Test was conducted to assess differences in body composition and functional capacities assessment between TM1 and TM2. Regarding results, body mass significantly increased in TM2 (p < 0.01), while increases in waist circumference and body fat percentage were not statistically significant. Functional capacity assessments revealed a significant decline in jumping performance (CMJ and SJ; p ≤ 0.01). Speed and agility assessments showed worse performance in TM2, significantly increasing 30 m sprint time (p ≤ 0.01). Balance indicators showed no significant differences, with mixed results in performance across different conditions. In sum, evaluating vertical jumps and long-distance maximum speed (i.e., 30 meters) could be valid tests for measuring and controlling fatigue in young elite handball players. Future research should regularly monitor young handballers after the competition to analyze the entire fatigue recovery process.
- Aulas de educação física baseadas na educação desportiva: uma revisão sistemáticaPublication . Góis, Francisca Maria Damasceno; Gouveia, Élvio Rúbio; Sarmento, Hugo; Peralta, Miguel; Marques, AdilsonO presente trabalho teve como objetivo sumarizar as evidências de estudos sobre como a participação em aulas de educação física (EF) baseadas na educação desportiva (EDE) tem sido relacionada a atividade física (AF) em adolescentes, sobretudo quanto a participação em atividade física moderada a vigorosa (AFMV), fatores psicológicos e sociais. Foi realizada uma revisão sistemática que incluiu 8 bases eletrônicas (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, PSYCINFO, ERIC e COCHRANE). Uma pesquisa inicial alcançou 162 títulos, permanecendo 149 após a retirada dos duplicados. Outros 10 estudos foram incluídos com base nas listas de referências, totalizando 159 estudos na fase de identificação. Na triagem, foram excluídas 89 referências, permanecendo 70 referências para análise de texto completo. Nesta etapa, foram excluídas 53 referências, resultando em 17 referências que preencheram os critérios de inclusão. Os estudos foram realizados entre 2002 e 2017, a maioria nos Estados Unidos. A maioria dos estudos reportou melhoras quanto aos fatores psicológicos e sociais, principalmente a motivação. Os dados sobre a participação dos adolescentes em AFMV foram contraditórios e inconclusivos, dificultando a compreensão do contributo do modelo para prática de AF dos alunos.
- Body Composition and Physical Fitness in Madeira YouthPublication . Martinho, Diogo V.; Gouveia, Élvio Rúbio; França, Cíntia; Lopes, Helder; Ihle, Andreas; Marques, Adilson; Rodrigues, Ana; Alves, Ricardo; Sarmento, HugoResearch on composition and physical fitness is lacking in school-aged children from Madeira. This study aimed to examine the frequencies of overweight and obese participants and, in addition, to compare the fitness levels of Madeira youth with reference data. Methods: The sample comprised 521 participants (n = 258 boys; n = 263 girls) aged 10.0–18.9 years old. Methods: Height and weight were measured. Body mass index (BMI) was calculated, and percent fat was derived from skinfolds. Tests detailed on FITESCOLA battery were performed. BMI was plotted against U.S. reference data and physical assessment contrasted with the cut-off points of FITESCOLA protocol and corresponding data developed in Portuguese youth. Results: The percentages of overweight and obesity were 15% (overweight) and 14% (obesity) for boys and 16% (overweight) and 6% (obesity) for girls. The median values of fat mass percentage were closely related to the cut-off standards; however, substantial variation was noted. Boys and girls tended to be below the recommendations of cardiorespiratory fitness. Conclusions: Sport participation should be promoted in Madeira to attain acceptable values of body composition and physical fitness levels.
- Body composition variations between injured and non-injured professional soccer playersPublication . Martins, Francisco; França, Cíntia; Henriques, Ricardo; Ihle, Andreas; Przednowek, Krzysztof; Marques, Adilson; Lopes, Helder; Sarmento, Hugo; Gouveia, Élvio RúbioProfessional soccer is characterized by its physical demands, making players’ exposure to high injury risks a growing problem. It is crucial to study the factors associated with injuries in professional soccer. This study aimed to investigate the relationship between age, body composition, and others variables related with the injury profle of professional soccer players of a specifc Portuguese team. Also, it analyzed the impact of the injury profle on soccer’s variations in body fat (BF%), skeletal muscle mass (SMM) and total body water (TBW) throughout the season. The sample comprised 31 male professional soccer players competing in the First Portuguese Soccer League. Older players had a higher prevalence of muscular injuries. Midfelders and forwards showed the highest number of muscular injuries during the season being quadriceps the most afected zone. Considering players’ BF% [Wilks’ Lambda = 0.42, F (7, 23) = 4.61, p= 0.002, r = 0.58], SMM [Wilks’ Lambda = 0.59, F (6, 23) = 2.70, p= 0.039, r = 0.41] and TBW [Wilks’ Lambda = 0.54, F (7, 23) = 2.80, p= 0.029, r = 0.46] there was a substantial main efect for the assessments performed throughout the season and the injury status. Age assumes relevance in explaining the injury profle. The impact of the injury profle on soccer’s variations in BF%, SMM and TBW throughout the season must be analyzed considering the clinical relevance.
- Cardiorespiratory fitness and telomere length: a systematic reviewPublication . Marques, Adilson; Gouveia, Élvio Rúbio; Peralta, Miguel; Martins, João; Venturini, Joed; Henriques-Neto, Duarte; Sarmento, Hugolength (TL). Studies were identified from searches in Cochrane Central, PubMed, Scopus, Sportdiscus, and Web of Science databases through July 2019. Eligibility criteria included: cross-sectional, prospective, and experimental study design; outcomes included TL; results expressed the relationship between cardiore spiratory fitness and TL; studies published in English, Portuguese, or Spanish. A total of 20 articles met the inclusion criteria. Sixteen studies (80%) reported a significant relationship between cardiorespiratory fitness, or training load, and TL. Better cardiorespiratory fitness or a large cardiorespiratory training load are associated with an increase in TL. Although, TL was related to regular moderate-to-vigorous aerobic exercise and cardiorespiratory fitness in older healthy humans, it was not related to cardiorespiratory fitness among young subjects. There seems to be a positive and significant relationship between cardiorespiratory fitness and TL, mainly among middle age and older people, which emphasizes the importance of cardiorespiratory fitness for healthy ageing. Therefore, endurance exercise and better cardiorespiratory fitness may regulate the TL in middle age and older adults, slowing the cellular ageing process.
- Characterization of Static Strength, Vertical Jumping, and Isokinetic Strength in Soccer Players According to Age, Competitive Level, and Field PositionPublication . Gouveia, João Nuno; França, Cíntia; Martins, Francisco; Henriques, Ricardo; Nascimento, Marcelo de Maio; Ihle, Andreas; Sarmento, Hugo; Przednowek, Krzysztof; Martinho, Diogo V.; Gouveia, Élvio Rúbio: Muscular strength is strongly related to speed and agility tasks, which have been described as the most decisive actions preceding goals in the soccer game. This study aimed to characterize the players’ strength indicators and to analyze the variation associated with age, competition level, and positional role. Eighty-three male soccer players from A team (n = 22), B team (n = 17), U-23 (n = 19), and U-19 (n = 25) participated in this study. Handgrip strength was assessed using a hand dynamometer (Jamar Plus+), countermovement jump (CMJ) and the squat jump (SJ) were evaluated using Optojump Next, and a Biodex System 4 Pro Dynamometer was used to assess the isokinetic strength of knee extension/flexion. Team A players showed increased lower-body strength compared to their peers, mainly through their increased vertical jumping capacity (i.e., CMJ and SJ; ps < 0.019), and superior performance in isokinetic assessments (i.e., peak torque, total work, and average power). Overall, older players outperformed their younger peers regarding vertical jumping, static strength, and average power in isokinetic strength (ps < 0.005). This study emphasizes the superior strength levels of professional soccer players compared with their lower-division peers, even after controlling by age. This information is of great value to sports agents and coaches, underlining the need to design and include strength-specific content during soccer training.
- Genetic influence on football performance: a systematic reviewPublication . Sarmento, Hugo; Marques, Adilson; Field, Adam; Martins, João; Gouveia, Élvio; Prieto Mondragón, Laura; Ordoñez Saavedra, Nestor; Rodríguez, Diego; Clemente, FilipePurpose. To systematically review and organise the available literature devoted to the topic of genetics and performance in football. Methods. A systematic search was conducted in accordance with the PRISMA guidelines in Web of Science, SPORTDiscus, and PubMed for original research published before October 2019. The following keywords were entered: ‘Soccer’ OR ‘Football’ AND ‘Genetic’ OR ‘Epigenic’ OR ‘Powergene’ OR ‘Genomic’ OR ‘Genotype’ OR ‘Polymorphism’ OR ‘Genetic marker’. Articles were screened by using pre-defined selection criteria, and methodological quality was assessed independently by 2 authors. Results. The electronic searches yielded 872 articles, and after the screening process, a total of 38 studies met the eligibility criteria and were subsequently included for review. Conclusions. The reviewed studies identified the most frequently addressed topics in this area of research: (1) performance related genes; (2) injury-related genes; (3) body composition-related genes; and (4) cardiac adaptations. This area of research is still at an early stage, and there is a need for studies to develop knowledge of genetics and its link with physical, technical, and cognitive performance in football with a view to facilitating talent identification in young players.

- Knee and hip muscle strength of male soccer players from different competitive levelsPublication . França, Cíntia; Martins, Francisco; Przednowek, Krzysztof; Marques, Adilson; Ihle, Andreas; Sarmento, Hugo; Gouveia, Élvio Rúbio; França, Cíntia; Pestana Martins, João Francisco; Marques, Adilson; Ihle, Andreas; Sarmento, Hugo; Gouveia, Élvio RúbioIn soccer, knee and hip muscle strength assessments have been recommended for injury prevention. The aims of this study were threefold: (1) to compare knee and hip muscle strength between professional players competing at different levels; (2) to compare strength performance according to the preferred leg (PL) and the non-preferred leg (NPL); and (3) to compare knee and hip muscle strength performance at two moments of the season. This study included 33 professional soccer players: 13 were in the elite group (EG), and 20 were in the sub-elite group (SEG). Body composition, isokinetic knee strength at 60º/s, and hip adduction strength were assessed at two different moments (M1 and M2). Values of peak torque (PT), peak torque/bodyweight (PT/BW), and the hamstring-to-quadriceps strength ratio (H:Q) for knee extensors (KEs) and knee flexors (KFs) for both legs were used for analysis. The statistical analysis included the Mann-Whitney U and the Wilcoxon Signed Rank tests. At M1, the EG presented a significantly better performance in KF PT/BW and in the squeeze strength test for the PL and the NPL (p 0.01). At M2, the EG performed substantially better in KE PT/BW and KF PT/BW (p 0.01). No substantial strength differences were observed in knee and hip muscle performance between the PL and the NPL. From M1 to M2, significant increases were found in knee strength in both groups (p 0.01). Overall, the EG players outperformed significantly their lower-division peers in strength assessments. The results indicate significant knee and hip muscle strength increases during the season, probably as a response to the exposure to training and competition.
- Lower limbs strength variations between injured and non-injured professional soccer playersPublication . Martins, Francisco; França, Cíntia; Hugo Sarmento; Ricardo Henriques; Krzysztof Przednowek; Marcelo de Maio Nascimento; Adilson Marques; Andreas Ihle; Gouveia, Élvio Rúbio; Sarmento, Hugo; Marques, Adilson; Ihle, Andreas; Gouveia, Élvio RúbioDue to its physical demands, professional soccer is becoming a real challenge regarding players’ exposure to high injury risk. Given its tight correlation with high-intensity actions, muscular strength is a crucial physical characteristic for soccer players. Therefore, the aims of this study are (a) to compare the vertical jumping performance during the season according to the injury profile, and (b) to investigate differences in isokinetic strength performance at the beginning and the end of the season. Twenty-one male professional soccer players (age: 26.0 ± 4.1 years, height: 181.0 ± 6.9 cm, body mass: 73.7 ± 6.9 kg) were assessed in isokinetic strength (Biodex System 4 Pro Dynamometer), and Optojump Next (Microgate, Bolzano, Italy). Isokinetic strength analyses considered the peak torque scores of knee flexors and knee extensors, according to the player's preferred and non-preferred limb. The countermovement and squat jump maximum height were assessed as lower body explosive strength indicators. No significant differences were found when comparing injured and non-injured players in vertical jump and isokinetic strength assessments. However, significant results were found when comparing both groups’ initial and final evaluation in isokinetic strength assessment, with both groups significantly improving their performance. Our findings indicate that the overall lower body strength performance was not a discriminant factor between injured and non-injury players. Thus, muscular strength assessment performance increased throughout the season independently of the injury profile. Future research needs to integrate other variables related to sports injuries since they seem to result from multifactorial causes.
