- 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.
- Lower body strength and body composition in female footballPublication . França, Cíntia; Saldanha, Carolina; Martins, Francisco; Nascimento, Marcelo de Maio; Marques, Adilson; Ihle, Andreas; Sarmento, Hugo; Campos, Pedro; Gouveia, Élvio Rubio; França, Cíntia; da Costa Saldanha, Carolina Filipa; Pestana Martins, João Francisco; Marques, Adilson; Ihle, Andreas; Sarmento, Hugo; Pereira Campos, Pedro Filipe; Gouveia, Élvio RúbioAbstract Lower-body strength plays a crucial role in football performance and injury prevention, and thus, monitoring of strength variables has become crucial in the training process. This study aims to (1) assess knee muscle strength performance through intra- and inter-limb asymmetries and (2) examine the relationships between knee muscle strength, body composition, and vertical jump performance (squat jump and countermovement jump). Twenty-seven semiprofessional female football players (21.5 ± 4.9 years) were evaluated for body composition, isokinetic knee muscle strength (60º/s and 180º/s), and vertical jump tasks. Peak torque (PT), peak torque/body weight (PT/BW), bilateral strength deficit, and the hamstring-to-quadriceps strength ratio (H/Q) for knee extensors (KE) and flexors (KF) in both the preferred and non-preferred legs. The H/Q ratio and the bilateral strength deficit revealed no significant intra- or inter-limb asymmetries in knee muscle strength. Strong correlations were found between vertical jump performance and KE strength at both 60º/s (p ≤ 0.01) and 180º/s (p ≤ 0.01). Additionally, a significant negative correlation was observed between vertical jump performance and body fat percentage (p ≤ 0.01). These findings highlight the critical role of knee muscle strength in explosive tasks and underline the negative impact of higher body fat on lower-body strength performance.
- Weekly External Load Performance Effects on Sports Injuries of Male Professional Football PlayersPublication . Martins, Francisco; Marques, Adilson; França, Cíntia; Sarmento, Hugo; Henriques, Ricardo; Ihle, Andreas; Nascimento, Marcelo de de Maio; Saldanha, Carolina; Przednowek, Krzysztof; Gouveia, Élvio RúbioOne of the most challenging issues professional football players face throughout their careers is injuries. Those injuries often result from suboptimal training programs that were not designed according to the players’ individual needs. This prospective study aimed to examine in detail the effects of sports injuries on professional football players’ weekly external load performances. Thirty-three male professional football players were monitored using 10-Hz Global Positioning Sys tem (GPS) units (Apex pro series, StatSports) during an entire season. The variables considered in the analysis were total distance (TD), high-speed running (HSR), accelerations (ACC), and decelerations (DEC). The comparisons were made between the four-week block before injury (–4T), four-week block after return (+4T), and players’ season averages (S). Players displayed significantly higher values of TD, HSR, ACC, and DEC in the –4T, compared to the other two moments (+4T and S). Furthermore, the comparison between the +4T and S showed no significant variations in the GPS metrics. It was shown that a significant increase in players’ weekly external load performance over a four–week period may have a negative effect on the occurrence of injuries from a professional football standpoint. Future research should consider the effects of injury severity on players’ external load variations.
