- 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.
- Participation in Physical Education Classes and Health-Related Behaviours among Adolescents from 67 CountriesPublication . Martins, João; Marques, Adilson; Gouveia, Élvio Rúbio; Carvalho, Francisco; Sarmento, Hugo; González Valeiro, MiguelThe present study sought to examine the associations between participation in physical education (PE) classes and a range of health-related behaviours among adolescents. Secondary analysis of self-reported data from the Global Student Health Survey, collected between 2010 and 2017 from 222,121 adolescents (N = 117,914 girls; 49.0%; aged 13–17 years) from 67 countries and five world regions, was carried out. Participation in PE classes (0, 1–2, ≥3 days/week) was the independent variable. Physical activity (PA); sedentary behaviour (SB); active travel to school; fruit, vegetables, and alcohol consumption; and smoking; as well as adopting ≥5 of these healthy behaviours; were the dependent variables. Complex samples logistic regressions were performed to explore the associations between participation in PE classes and health-related behaviours. The results revealed that 18.2% of adolescents did not take part in PE classes. A total of 56.7% and 25.1% of adolescents reported participating in PE classes on 1–2 and ≥3 days/week, respectively. Only 26.8% of adolescents adopted ≥5 healthy behaviours. Participation in PE classes was positively associated with PA, active travel, fruit consumption, and vegetable consumption (only for ≥3 days/week), but was negatively associated with meeting SB recommendations, and with not smoking (only for girls and ≥3 days/week). Overall, PE participation was positively associated with adopting ≥5 healthy behaviours, with favourable results found for those who attended more PE classes. The findings revealed a positive association between participation in PE classes and a range of health-related behaviours among adolescents. This suggests that, worldwide, quality PE should be delivered at least 3 days per week up to daily to promote healthy lifestyles among adolescents.
- 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.
