- 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.
- Move4Future: implementation and effects of a pilot physical exercise programme for children and youth at risk from multi problem familiesPublication . Mercê, Cristiana; Simões, Vera; Ramos, Liliana; Silva, Miguel; Brígida, Nancy; Vitorino, Anabela; Branco, Marco; Oliveira, Rafael; Oliveira, Rafael; Mercê, Cristiana; Simões, Vera; Ramos, Liliana; Vitorino, Anabela; Branco, MarcoIntroduction and Objective: Multi-problem families include several risk factors (e.g., mental health and weight issues). Physical exercise could be a strategy to prevent, treat and overcome numerous disorders. Thus, this study aimed to analyze the effects of implementing the Move4Future pilot program, in children and adolescents, on the following variables: i) anxiety levels, ii) body composition, iii) physical fitness, and iv) physical activity levels. Methodology: Ten participants (10.61±2.40 years) completed a 12-week physical exercise program with a weekly frequency of one session and were assessed at baseline and post-intervention. The Re vised Manifest Anxiety Scale for Children, body mass, height, triceps skinfold, calf skinfold, re laxed arm circumference, waist circumference, calf circumference, and the FITescola® battery tests (push-ups, horizontal jump, agility, shoulder flexibility and lower limb flexibility) were applied. Results and Conclusions: The main results showed a lower anxiety trait, although this change was not statistically significant (z=-1.832, p=0.067), a significant increase in stature (z=-2.197, p=0.028), a significant decrease in body mass index (z=-2.366, p=0.018), and in waist circum ference (z=-2.201, p=0.028). The Move4Future pilot program shows improvement in average values of anxiety levels, body composition and upper strength in physical fitness. However, a multi-component intervention, including families and more sessions per week, may be im portant for better results.
- The Quality of Life of Former Portuguese Football PlayersPublication . Teixeira, Eduardo; Silva, Carlos; Romero, Félix; Costa, João Paulo; Vicente, António; Silva, Carlos; de Lima e Cunha Hopffer Romero, Félix Luís; Teixeira, Eduardo Filipe; Costa, João PauloBackground: The demands of playing professional football can have an impact on an individual’s quality of life (QoL), which may remain into retirement. Given limited evidence exists regarding the QoL in former football players, this study aimed to assess QoL among Portuguese former players according to career duration, career end period, competitive level, tactical-positional status, international status, academic qualifications, serious injuries in career, and current profes sional football connection. Methods: The study included 84 Portuguese former football players (48.8 ± 8.2 years old) who transitioned to retirement between 1988 and 2018. The WHOQOL-BREF questionnaire was used to assess QoL perceptions, and the Portuguese version was validated. Results and Discussion: The former players have positive QoL indicators, both in general and across the four domains, namely in terms of the physical, psychological, and social relationship and environment. There were no statistically significant differences in QoL between the defined categories for career end period, competitive level, tactical-positional status, international status, and current professional football connection. Likewise, there was no significant correlation between QoL and career duration. In contrast, there were significant differences in general QoL (p < 0.023) and in the physical domain (p < 0.001) between former players with different academic qualifications. A significant correlation was found between the number of severe injuries sustained in a career and QoL in the physical domain (R = −0.300, p = 0.006). Conclusions: There are no concerning QoL results presented by former players. However, the number of severe injuries sustained during the career was associated with a lower QoL, while holding higher academic qualifications demonstrated higher general and physical QoL. Studies with larger samples should be conducted to confirm these trends.
- The relationship between individualised speed thresholds and changes in aerobic fitness in elite professional youth soccer players. A case studyPublication . KAVANAGH, Ronan; McDAID, Kevin; Rhodes, David; ALEXANDER, Jill; Harper, Damien; Oliveira, Rafael; Oliveira, Rafael; Berran, Kieran; Connor, Mark; ZMIJEWSKI, Piotr; Morgans, RylandBackground: This study aimed to examine the dose-response relationship between train ing load and aspects of physical fitness in English Premier League (EPL) U23 soccer players. Mate rials and Methods: Seven male EPL U23 outfield soccer players (age 20.1±1.1 years) participated in this study and performed the Bronco test on five occasions within one season. Individualised run ning thresholds were employed using maximal aerobic speed (MAS), anaerobic speed reserve (ASR) and maximal sprint speed (MSS) values utilising a GPS system. Results: No significant differences in the Bronco performance between the tests (p > 0.05, ES = 0.101) were observed. Distance covered above 30% ASR (r = -0.51) and time spent above 30% ASR (r = -0.54) over a 2-week period displayed a moderate negative linear relationship with Bronco performance. Conclusions: ASR-based training load variables displayed the highest correlations with Bronco results. These findings support prac titioners to individualise high-speed running thresholds.
- Severe Injuries of Former Portuguese Football Players: a Post-Career Burden?Publication . Teixeira, Eduardo; Silva, Carlos; Romero, Félix; Miguel, Mauro; Vicente, António; Teixeira, Eduardo Filipe; de Lima e Cunha Hopffer Romero, Félix Luís; da Conceição Miguel, Mauro; Pedro Andrade Vicente, António: Background/Objectives: Football players have a high injury risk due to the physical demands of their profession, which can negatively affect their quality of life (QoL) in the long term. The aim of this study is to characterize the severe injuries that former Portuguese football players suffered throughout their professional careers and investigate the resulting impacts on the physical domain of QoL after retirement. Methods: This study includes 84 former Portuguese football players (48.8 ± 8.2 years) who underwent reform between 1988 and 2018 and played in professional leagues (15.2 ± 3.2 years of career duration), namely, first division leagues (n = 43) and secondary division leagues (n = 41). Quantitative and qualitative interview data are used by a validated interview guide and from results of the physical domain obtained by the application of the World Health Organization Quality of Life questionnaire (WHOQOL-Bref). Results: Former players had 2.1 ± 1.5 severe injuries throughout their careers. The most common injuries involve the knee (47.5%) and foot/ankle (17.2%), with the anatomical area of the knee as the most likely to require surgical intervention (60%). The association between tactical-positional status and the incidence of severe injuries is significant, with defenders sustaining less severe injuries throughout their careers. This study found a statistically significant linear model (F(1.82) = 8.089, p < 0.006) that explains 7.9% of the variation in the physical domain of QoL (R2ajuste = 0.079). For each severe injury sustained throughout a career, there is an estimated decrease of 2.7 values in QoL perception in the physical domain. Conclusions: The higher the number of severe injuries sustained during a career, the lower the perception of QoL in the physical domain of former players in their post-career. These findings highlight the need to optimize training programs and injury prevention and recovery protocols for long-term QoL improvement in the physical domain of football players.
