- Treinador-Adjunto e analista na 1ª Divisão Nacional Sub-15. A influência do número e posicionamento das balizas em jogos reduzidos condicionadosPublication . Freitas, Rafael Lanceiro Bernardes; Miguel, MauroO presente relatório descreve o estágio realizado no âmbito do Mestrado em Treino Desportivo – Especialização em Futebol, desenvolvido na Associação Académica de Santarém. A prática dividiu-se entre a função de treinador-adjunto e analista da equipa Sub-15 (1ª Divisão Nacional de Iniciados) e a de treinador principal da equipa Sub-9 (Traquinas). O estágio teve como objetivos principais aplicar conhecimentos teórico-práticos, desenvolver competências técnico-profissionais e realizar investigação científica. A componente prática do estágio permitiu a integração plena na dinâmica dos treinos e competições, com responsabilidades que incluíram o planeamento, operacionalização e análise do treino, elaboração de relatórios de jogo, observação de adversários e aplicação de princípios de treino ajustados aos diferentes escalões etários. Paralelamente, foi conduzido um estudo centrado na influência do número e do posicionamento das balizas em Jogos Reduzidos Condicionados (JRC), com o objetivo de perceber de que forma esses elementos condicionam as ações técnico-táticas dos jogadores, havendo também resultados comparativos entre dois grupos distintos (mais e menos utilizados). Os resultados revelaram que menos balizas potenciam maior número de dribles, enquanto mais balizas favorecem maior frequência de passes progressivos. Verificou-se também uma superioridade quantitativa do grupo 1 em relação ao grupo 2, na maioria das várias tipologias de passe. Conclui-se que a manipulação das balizas influencia o comportamento técnico-tático dos jogadores, destacando a importância do design dos JRC na formação desportiva. O relatório aborda ainda os principais desafios, aprendizagens e reflexões do percurso desenvolvido ao longo da época.
- Comparison of external load during differing microcycle structures across two competitive seasons in elite female portuguese soccer playersPublication . Espada, Mário C.; Santos, Fernando J.; Nalha, Matilde; Zmijewski, Piotr; Morgans, Ryland; Oliveira, Rafael; Brito, João Paulo; FERNANDES, RENATOThis study aimed to: (i) compare the accumulated load between three and four training sessions per week plus a match across two consecutive seasons in elite female soccer players, and (ii) compare the training/match ratio (TMr) of external load. Data from 10 players in each season were analysed during the study period. The microcycle structure of the first season included three training sessions (3dW) and a match per week, while the second season included four training sessions (4dW) plus a match per week. The following measures were used for analysis: duration, total distance, high-speed running distance (HSR,>15 km/h), number of accelerations (ACC,>1–2 m.s−2 [ACC1];>2–3 m.s−2 [ACC2];>3 4 m.s−2 [ACC3];>4m.s−2 [ACC4]) and decelerations (DEC,<1–2m.s−2 [DEC1]; <2–3 m.s−2 [DEC2];< 3–4 m.s−2 [DEC3];< 4m.s−2 [DEC4]). The accumulated load was calculated by summing key metrics for all training sessions and matches, while TMr was calculated by dividing the accumulated load by match data. The main results showed that all variables showed meaningful differences (p<0.05) except for ACC4 and DEC4. Specifically, total distance was higher in 3dW than 4dW (p=0.007), while the remaining variables were higher during 4dW. Moreover, all TMr were higher in 4dW than 3dW (p<0.001 for all variables except for ACC4 and DEC4). As expected, this study showed that adding one training session per week increased accumulated load and TMr for several key variables.
- The professional careers of former portuguese football players: a sociodemographic and professional approachPublication . António Vicente; Teixeira, Eduardo Filipe; de Lima e Cunha Hopffer Romero, Félix Luís; da Conceição Miguel, Mauro; Silva, Carlos; FerreiraIntroduction: The study is aimed to identify sociodemographic and professional characteristics related to the careers of former Portuguese football players. Methodology: The sample consisted of 84 Portuguese former players (48.8 ± 8.2 years old) with at least 8 years of professional experience, who finished their careers between 1988 and 2018. Quantitative data was collected from a validated semi-structure interview guide. Results and Discussion: Former Portuguese players had a career of 15.2 ± 3.1 years with more 6.4 ± 2.2 years of youth federated formation. Significant statistical differences were seen between former players with different competitive levels (t(71)=3.843; p=0.001) and international status (t(82)=-2.740; p=0.008). During their careers, 36% accomplish academic formation and 61.9% pursued technical education. Academic habilitation was statistically significant relationships with competitive level (χ2(1)=9.655; ρ=0.002) and international status (χ2(1)=6.930; ρ=0.008), unlike what happened with technical qualification (p>0.05). The majority of former players marry (83.3%) and have children during the career (82.2%). The divorce rate is 15%. Residential mobility is high (8.1 ± 5.55 years). The professional incomes were considered high or very high and 16.7% of former players developed addictions during their career. Conclusion: Former players with higher competitive levels and international status tend to have longer careers. Conversely, they tend to invest less in academic formation. The results reveals that the football career is brief and presents stress and risk factors, mainly at higher competitive levels. The findings contribute to a better understanding and discussion of the professional careers of former Portuguese football players.
- Contextualized acceleration and deceleration profiles of elite soccer players during English Premier League match-play. The effect of possession, positional demands and opponent rankingPublication . Morgans, Ryland; Mandorino, Mauro; Ryan, Ben; Zmijewski, Piotr; Moreira, Alexandre; Oliveira, RafaelThis study aimed to compare accelerations (ACC) and decelerations (DEC) when in- (IP) and out of-possession (OP) during official English Premier League (EPL) match-play over three consecutive seasons considering playing position, match location and opponent ranking. Match data from 31 male professional soccer players was obtained via an optical tracking system. Playing position significantly influenced ACCIP, DECIP, and DECOP. Ranking difference and match location were significant predictors for DECIP, ACCOP, and DECOP. An increase in ranking difference was associated with higher DECIP. Conversely, in the out-of-possession phase (ACCOP and DECOP), a decrease in these parameters with increasing ranking difference was observed. Regarding match location, positive β coefficients suggested that DECIP, ACCOP, and DECOP values were significantly higher during away matches compared to home matches. A significant interaction (playing position × ranking difference) was reported for DECOP (𝛽 = 0.035, p = 0.013). Interestingly, DECOP actions decreased with increasing ranking difference across all playing positions except for wingers. In conclusion, these findings highlight that distinct contextual factors influence ACC and DEC performance during in- and out-of-possession phases of EPL match-play.
- Does running performance relate to the market value of elite male soccer players? A case study from the FIFA world cupPublication . Kılcı, Abdullah; Koç, Muhammed Emin; Binokay, Hülya; Erdoğan, Ali; Kamiş, Okan; Oliveira, RafaelThe study main aim was to investigate: the relationship between running performances and market values of soccer players playing in the 2022 FIFA World Cup, by playing position and all players; the comparisons by playing position; to analyse the relationship between running metrics and market values of the highest and lowest players ranked players. The relationship between running metrics and market values of 306 soccer players who participated in the tournament and played full time, as well as the 40 players with the highest (n = 20) and lowest (n = 20) market values was analysed. Overall, there was a very weak correlation between market values and total distance (r = 0.149), zone 3 (r = 0.153), zone 4 (r = 0.139), zone 5 (r = 0.160), high-speed runs (r = 0.132), sprints (r = 0.147), and top speed (r = 0.194) for all players (p < 0.05). Defenders showed very weak positive correlation between market values and top speed (r = 0.155, p < 0.05). Midfielders showed weak positive correlations between market values and zone 4 (r = 0.302, p < 0.05) and zone 5 (r = 0.369, p < 0.001), sprints (r = 0.367, p < 0.001), and top speed (r = 0.304, p < 0.05). Forwards showed no correlations (p > 0.05). While there is no significant correlation between running metrics and market value for players with the lowest market value (p > 0.05), there was a moderate negative correlation between total distance (r=-0.577) and zone 2 (r=-0.612) for the 20 players with the highest market value (p < 0.05). Moreover, there was a weak correlation with zone 5 (r = 0.450) and a moderate correlation with the top speed values (r = 0.596) (p < 0.05). Weak correlations between soccer players’ running performance and market values suggest that different running thresholds are important metrics, although other factors (e.g., technical skill, age, national and team club) may influence this relationship. In conclusion, since coaches and scouts aim to recruit relatively talented players within the limits of their budgets, selecting athletes with high aerobic and anaerobic performance, particularly those with a strong high-intensity running profile, can contribute to team success and potentially generate high transfer revenues in the future.
- How learning to cycle influences lifestyle: an eight country pooled analysis and person-centered approachPublication . Estevan, Isaac; Meester, An De; Veldman, Sanne L.C.; Lopes, Frederico; Hasanen, Elina; Laukkanen, Arto; Tortella, Patrizia; Sá, Cristina; Jidovtseff, Boris; Fujikawa, Ricardo; García-Massó, Xavier; Cordovil, Rita; Branco, Marco; Mercê, Cristiana; Catela, DavidCycling plays a key role in the promotion of individual, community, and planetary health. However, no previous study has explored the interplay between the process of learning to cycle and cycling habits, adopting a person-centered approach. To understand which variables promote the learning process (i.e., acquisition) and lifelong bicycle use on a daily and recreational basis (i.e., engagement), the aim of this study was to identify different clusters of individuals with similar characteristics related to their cycling acquisition and engagement. Methods: A cross-country pooled sample of 8542 individuals aged 28.9 ± 14.4 years (58.5 % female) was assessed via online questionnaire. A Self-Organizing Map (SOM) was used to classify and visualize the values of individuals in the variables tested. Results: A K-means cluster analysis resulted in seven profiles. Participants in profiles characterized by a relatively old age to learn to cycle (i.e., 7-8 years-old; n > 1500 mainly from Mexico and the United Kingdom) typically learned to cycle on a conventional bicycle, were taught by their father, mother, or both, and mainly cycle for leisure. Participants in profiles characterized by a relatively young age to learn to cycle (i.e., 5 years old; n > 1500 mainly from Belgium and Finland)
- Analysis of health and wellness programs and their relationship to injuries in football and futsal players: a systematic reviewPublication . Tavares, Bárbara; Mercê, Cristiana; Oliveira, RafaelIntroduction: Football and futsal are associated with a high risk of injuries and consequently, the development of mental health problems. Health and wellness programs aimed at reducing the incidence of injuries, but these areas remain insufficiently explored in the literature, there fore, their effectiveness is still uncertain. Objective: This study aimed to present a systematic review that analyzes the effects of health and well-being programs on the incidence of injuries in football and futsal athletes. Methodology: A search was conducted in PubMed, EBSCO, and Web of Science databases to se lect relevant literature on the topic. The selected literature was based on health and wellness programs applied to football players, and after implementation, the difference in the incidence of injuries examined. Studies that used experimental study design to compare athletes before and after the intervention were selected. Results: Based on the physiotherapy evidence database scale, criteria were applied to assess the interventions’ evidence. Seven studies were classified as having good methodological qual ity, while four were classified as moderate and one as poor. From a total of 329, 12 studies were selected based on the eligibility criteria. Conclusions: The different studies selected addressed various types of programs (e.g., Mindful ness, Stress Inoculation Therapy and Biofeedback, Psychological and physiotherapy, Yoga). The programs reduced the incidence of sports injuries in football athletes and improved individual and team performance and reduced muscle tension. However, research is scarce, while studies are needed.

- Learning to cycle: body composition and balance challenges in balance bikes versus training wheelsPublication . Mercê, Cristiana; Cordovil de Matos, Rita; Mafalda Bernardino; dos Santos Bernardino, Mafalda Filipa; Branco, Marco; Catela, DavidAbstract: Background/Objectives: Empowering our children and youth to cycle empowers them to pursue a healthier, fuller, and more responsible life. The present study implemented the Learning to Cycle program with the following aims: (i) to promote learning to cycle; (ii) to investigate and compare the use of different learning bicycles, i.e., balance bicycle (BB) and bicycle with training wheels (BTW); (iii) to investigate the influence of body composition during this learning process. Methods: The program was implemented through a quasi-experimental study involving two intervention groups, with pre- and post-test evaluations. The program was applied to 50 children (M = 5.82 ± 0.94 years, 23 girls) who did not know how to cycle previously. One group explored the BB and the other the BTW for six sessions, followed by four more sessions with the conventional bicycle (CB) for both groups. The assessment of independent cycling was considered as the ability to perform, sequentially and unaided, and the various cycling milestones: self-launch, ride, and brake. The children’s body composition was accessed by the BMI’s percentile and classification according to their age and sex. Results: The program had a success rate of 88.24% for acquiring independent cycling, with 100% success in the BB group and 76.92% in the BTW group. The BB children learned significantly faster to selflaunch, ride, brake, and cycle independently. Children with higher BMI percentiles faced greater challenges in achieving balance milestones. Conclusions: BB are recommended, especially for overweight and obese children, as they help develop balance from the onset, and showed to be more efficient in learning to cycle than the BTW.
- Effects of a 16‑week high‑speed resistance training program on physical and cognitive function in community‑dwelling independent older adults: a clinical trialPublication . Martins, Alexandre Duarte; Batalha, Nuno; Fernandes, Orlando; Gonçalves, Bruno; Oliveira, Rafael; Brito, João PauloPurpose This study investigated the effects of a 16-week high-speed resistance training (HSRT) program on physical and cognitive function in independent older adults. Methods Seventy-nine participants were assigned to an intervention group (IG, N= 40, 68.50 ± 3.54 years) or a control group (CG, N = 39, 72.08 ± 5.89 years). The IG completed 60–70 min of supervised HSRT three times weekly for 16 weeks. All concentric actions were continuously monitored with a BEAST™ sensor. Physical function was evaluated by five tests: chair‐stand, timed up and go (TUG), seated medicine ball throw (SMBT), six-minute walk (6MWT), and handgrip strength. General cognitive function was assessed with the mini-mental state examination (MMSE). Results The intervention could induce significant improvements in favor of the IG (p < 0.001) for chair-stand ( 2 p = 0.736), TUG test ( 2 p = 0.635), SMBT ( 2 p = 0.331), 6MWT ( 2 p = 0.386), and handgrip strength test for dominant ( 2 p = 0.448) and non-dominant side( 2 p = 0.388), as well as in general cognitive function (MMSE, p = 0.001, 2 p = 0.146). Conclusions The 16-week HSRT program led to substantial enhancements in both physical and cognitive function. Inter estingly, the HSRT program, tailored to general velocity zones, proved to be a safe and motivational approach to physical exercise within this population.
