- Bilateral asymmetry and the relationship between unilateral isokinetic strength and balance performance in male adolescent football playersPublication . França, Cíntia; Martins, Francisco; Martinho, Diogo; Ihle, Andreas; Marques, Adilson; Sarmento, Hugo; Clemente, Manuel; Przednowek, Krzysztof; Campos, Pedro; Gouveia, Élvio Rúbio; França, Cíntia; Pestana Martins, João Francisco; Gouveia, Élvio RúbioMuscle strength and balance ability have been related to injury prevention and game actions performance in football. The aims of this study are twofold: (1) to examine bilateral asymmetries in isokinetic strength and balance assessments, and (2) to evaluate the relationship between muscle strength and balance measures. Eighty-eight male adolescent football players were assessed for body composition (InBody 770), isokinetic strength (Biodex System 4 Pro Dynamometer), and balance performance (Biodex Balance System). Paired samples t-tests were conducted to determine bilateral differences in strength and balance. Pearson correlations and multiple linear regression analyses evaluated the relationship between strength and balance. No significant bilateral strength differences were observed in knee flexors (KF) and knee extensors (KE) peak torque (PT) scores. No bilateral differences were found for balance measures, except in the lateromedial stability index, which was better while performing with the preferred leg (p ≤ 0.01; d = 0.29). Significant correlations were found between KE PT and balance tasks (p ≤ 0.01). KF and KE PT shared between 18 and 22% of the common variance in the overall stability index in the non-preferred and preferred leg, respectively. Monitoring strategies of bilateral asymmetries may be crucial to enhance performance in tasks underpinned by unilateral movements, such as changes of direction and sprints, and to identify players at risk of injury. Adopting these strategies during the early stages of football training might be crucial for players’ long-term development.
- Change in spatiotemporal parameters during running at different degrees of inclination: systematic reviewPublication . Marszałek, Patryk; Przednowek, Krzysztof; França, Cíntia; Martinho, Diogo V.; Marques, Adilson; Ferrari, Gerson; Paśko, Wojciech; Gouveia, Élvio Rúbio; França, Cíntia; Martinho, Diogo; Marques, Adilson; Gouveia, Élvio RúbioBackground:Running is one of the simplest and most popular forms of exercise. Biomechanical evaluation of running is one of the elements of evaluating running technique and, consequently, improving sports performance. Running uphill and downhill is one of the components of daily running but also an element of training used by recreational runners. The aim of this study is to optimize running training and minimize the risk of injury by identifying changes in the spatiotemporal structure of running at different inclinations. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The protocol has been registered on the international platform INPLASY under the number INPLASY202430094U2. The search was conducted up to 30 March 2024 using the Scopus, PubMed, and Web of Science databases. Results: Spatiotemporal parameters were most frequently analyzed at 2.8–3.35 m/s velocities and inclinations in the range of −11% to 11%. Decreases in stride length (SL) and flight time (FT), and increases in step frequency (SF) were the most frequently reported changes from all parameters analyzed as a function of inclination and velocity. Significant increases or decreases in individual parameters were more often observed for positive inclination values than negative ones. Conclusions: The heterogeneous results of the study limit the possibility of determining the changes that occur in the spatiotemporal structure of the run under the impact of different inclinations. The variation in the results for negative inclination values indicates the different characteristics of running uphill and downhill. However, for uphill running, SF, SL, and FT are closely related to the increase in inclination.
- Emerging technologies to promote fans interaction in football events: a systematic reviewPublication . Martins, Francisco; França, Cíntia; Santos, Francisco; Martinho, Diogo; Saldanha, Carolina; Gouveia, Élvio RúbioReview question / Objective: The search terms used for this review were constructed using the PICOS framework: (1) population were people in general of both genders and any age, (2) studies based on digital technologies used in football sportive events, (3) comparisons made in the domains of motivation, interaction, satisfaction and interest, (4) data reporting the use of digital tools (studies with no results reported will be considered, besides not having outcomes), (5) Intervention studies with a pre and post-test design, descriptive studies, theorical studies, and protocol proposals, and (6) articles written in English, Spanish or Portuguese. Condition being studied: Our concern is with the acceptance of the fans returning to the stadium with normality after a pandemic period. In addition, we also want to understand what kind of interactive applications are already on the market or with their well defined protocols that intend to increase fan interaction at live games, increasing their motivation to go to the stadium and to have accurate and updated live information.
