- Analytical and Ecological Approaches to Aerobic and Anaerobic Conditioning in FootballPublication . Morgans, Ryland; Oliveira, Rafael; Oliveira, Rafael; Silva, Rui; Beato, Marco; Bishop, Chris; Turner, AnthonyResearch in professional football has shown that the physical demands of competitive match-play have substantially increased over the last few decades (Carling et al., 2016) as well as the training demands (Oliveira et al., 2022). As such, the role of support staff has developed to provide theoretical, scientific, and practical support to the manager in a variety of areas. These include performance analysis, strength and conditioning, and the integration of technical and tactical elements. The role of fitness and conditioning staff is to have knowledge of scientific literature and analyze performance data to condition and recover players appropriately to deal with the ever-evolving demands of elite football competition.

- Characteristics of physical exercise programs and their effects on quality of life and functional capacity in Individuals with chronic obstructive pulmonary disease: a scoping review.Publication . Ceylan, Halil; Soares, Maria de Brito; Martins, Alexandre Duarte; Vasconcelos, Tiago; Alves, Susana; Oliveira, Rafael; Brito, João Paulo; MOUTÃO, JOÃOBackground and Objectives: Individuals with chronic obstructive pulmonary disease (COPD) often exhibit some degree of intolerance to physical exercise and several limitations in daily activities. Therefore, the objective of this study was to conduct a scoping review on the characteristics—frequency, intensity, time, and type (FITT)—and the effects of exercise programs on quality of life and functional capacity in individuals with COPD. Materials and Methods: The present review included 21 studies that were scoping-reviewed to describe their main findings and training characteristics. Results: The participants across studies ranged in age from ~39 to 76 years with mild to very severe COPD stages. The results showed that, among all studies, eleven used cardiorespira tory training (e.g., walking or cycling), five used strength training (e.g., exercises with elastic bands or traditional resistance training), and five implemented combined training (i.e., cardiorespiratory and strength exercises). Conclusions: Overall, all training protocols improved aerobic capacity (cardiorespiratory training), strength (resistance training), and both capacities together (combined training). In conclusion, this review provided com plementary insights to existing exercise prescription guidelines, particularly concerning cardiorespiratory, strength, and combined training in individuals with COPD. However, the methodologies of the training protocols varied widely, and detailed descriptions of FITT components were often incomplete or lacking clarity, especially regarding the specific exercises used. Future research should include more comprehensive spirometry variables such as forced expiratory volume 1 or forced vital capacity, as these are critical for deter mining COPDstages. Thus, there is a clear need for more high-quality research with robust methodological design in the context of exercise interventions for individuals with COPD.
- 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.
- Comparisons of running and accelerometry based measures between playing positions in touch rugby. A case study of an amateur male teamPublication . Oliveira, Rafael; Nalha, MatildeBackground: The main objective of the present study was to quantify the external load of the games that belong to a national tournament by comparing playing positions. A secondary objective consisted in comparing the match-to-match variations. Methods: Fourteen players (four links, four middles and six wings) were included (age: 39.36 ±5.83 years; body mass index: 26.65 ± 4.13). Participants were monitored during a tournament. ThroughGpexepro2, thefollowingmeasureswerecollectedandrelativized per minute: total distance, forward distance, backward distance, zone 1 (0–1.50 m/s), zone 2 (1.50–3.00 m/s), zone 3 (3.00–4.00 m/s), zone 4 (4.00–5.50 m/s), zone 5 (5.50 7.00 m/s)andzone6(>7.00m/s),thenumberofaccelerationsanddecelerations, impacts and jumps. The absolute values of maximal speed, maximal acceleration speed and maximal deceleration speed were also used for analysis. Results: The main findings showed meaningful higher values of zone 4 (16.18 ± 1.89 vs. 5.56 ± 3.53), zone 5 (2.91 ± 0.81 vs. 0.38 ± 0.38), zone 6 (0.35 ± 0.24 vs. 0.00 ± 0.00), deceleration (0.56 ± 0.21 vs. 0.19 ± 0.12), maximal speed (23.56 ± 1.90 vs. 18.84 ± 1.24) and forward distance (102.20 ± 13.45 vs. 67.42 ± 17.40) for middles than wings (p < 0.05), with large to very large effect sizes. In addition, no differences were found when comparing external load data from all matches. Conclusions: The findings of this study showed a clear tendency of higher values for middles than links and wings which provides a deeper understanding of the positional activity profile of an Amateur Portuguese team allowing practitioners to adjust training with the common external load experienced in a tournament. Moreover, the analysis of match-to-match comparison revealed no differences through the competition day, which means a proper fatigue management.
- 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.
- Contextualized high-speed running and sprinting during English Premier League match-play with reference to possession, positional demands and opponent rankingPublication . Morgans, Ryland; Mandurino, Mauro; Beato, Marco; Ryan, Ben; Zmijewski, Piotr; Moreira, Alexandre; Ibrahim Ceylan, Halil; Oliveira, RafaelThis study aimed to compare high-speed running (HSR) and sprint distances (SD) 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. Results showed that during the IP phase, playing position emerged as the only significant predictor for both HSRIP and SDIP. Wingers showed the highest HSRIP compared to centre-backs who exhibited the lowest values (p < 0.001, ES = 4.19). Similar data were found for SDIP (p < 0.001, ES = 3.30). HSROP was significantly affected by both ranking difference (β = -0.039, p = 0.001) and match location (β = 0.369, p = 0.001). HSROP decreases as the ranking difference increases and tends to be higher during away matches (p = 0.001, ES = 0.24). SDOP was affected by both ranking difference (β = -0.023, p = 0.001) and match location (β = 0.166, p = 0.001) and decreased as the ranking difference increased. SDOP was also higher during away matches (p = 0.001, ES = 0.23). Additionally, a significant interaction was found between playing position and ranking difference (β = 0.005, p = 0.010). Lower ranking differences correspond to higher SDOP values. In conclusion, these findings highlight that by applying these IP and OP insights into practical coaching strategies, teams can potentially enhance individual physical performance and adaptability across different match situations and seasons.
- Dinâmica do momento angular: parâmetro de controlo na exploração de padrões motores na bicicleta de equilíbrio em criançasPublication . Bernardino, Mafalda Filipa dos Santos; Mercê, Cristiana; Branco, MarcoA bicicleta reflete a cultura humana e a sua utilização exige equilíbrio e manutenção da estabilidade. A criança e a bicicleta formam um sistema único, o qual procura manter a sua estabilidade através da rotação das rodas que atuam como giroscópios, em constante interação com os constrangimentos da tarefa, organismo e envolvimento. A massa distribuída em cada roda não é igual, assim, o primeiro estudo desta dissertação analisou a proporção de massa entre as rodas dianteira e traseira do sistema criança-bicicleta. A amostra incluiu 18 crianças com uma média de 4,89±0,35 anos, para as quais o centro de gravidade (CG) foi calculado através do método de coordenadas, e o CG da bicicleta através do método de equilíbrio. A roda traseira apresentou uma proporção de 78,8% da massa total e a dianteira 21,3%. Considerando que a aprendizagem de andar de bicicleta resulta da interação dinâmica entre os vários constrangimentos como a massa da criança (organismo), massa e raio da roda da bicicleta (tarefa), a distribuição de massa das rodas no sistema criança-bicicleta deve ser considerada para análises posteriores da estabilidade. Neste sentido, e considerando igualmente que esta aprendizagem pode ser facilitada através de mudanças nos parâmetros de controlo, o segundo estudo investigou se o momento angular (MA) da bicicleta é um parâmetro de controlo para os padrões de ciclar na bicicleta de equilíbrio (BE). Este estudo incluiu recolhas transversais durante a aplicação de um programa de aprendizagem de ciclar. Participaram 25 crianças com uma média de 5,16±0,89 anos, as quais foram convidadas a usar livremente a BE, antes e depois da intervenção de 6 sessões com a BE. Os dados foram recolhidos através de vídeo e posteriormente categorizados para permitir a identificação dos padrões de ciclar. Adicionalmente, foram recolhidos dados de velocidade angular através de um sensor inercial fixado na roda da bicicleta, permitindo o cálculo posterior do MA. Os resultados evidenciaram que, à medida que o MA aumenta, as crianças tendem a transitar entre os padrões de ciclar. Com MA mais baixo, o padrão preferido consistiu em caminhar. A partir de 0,53 kg·m²/s, a maioria das crianças transitou para correr. E, a partir de 1,1162 kg·m²/s, a maioria das crianças transitou novamente para o padrão de planar. Com base nestes resultados, propomos que o MA é um parâmetro de controlo para a BE, sendo a velocidade linear uma expressão dele. Em conclusão, as características específicas da bicicleta e da criança influenciam o momento angular e, consequentemente, a transição entre os padrões. Todos estes aspetos devem ser considerados na promoção da aprendizagem de ciclar.
- 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.
