- 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.
- Concurrent validity and reliability of global positioning systems for measuring intense running and peak speed performance: a systematic reviewPublication . Hadi Nobari; Alexandre Duarte Martins; João Paulo Brito; Elena Mainer-Pardos; Pablo Valdés-Badilla; Rafael Oliveira; RafaelThe current systematic review aimed to analyse studies on the concurrent validity and reliability of microelectromechanical devices for measuring intense running and peak speed performance. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using EBSCO, PubMed, Scielo, Scopus, SPORTDiscus and Web of Science. Keywords and synonyms were entered in various combinations in the title, abstract, or keywords: (“Global positioning system” OR “Global Navigation Satellite System” OR “GPS”) AND (Validity OR Accuracy OR Reliability OR Precision OR Repeatability OR Reproducibility OR Consistency) AND (“sprint” OR “peak speed” “top seed” OR “maximal speed”). The risk of bias was assessed using the Appraisal tool for Cross-Sectional Studies. From 839 studies, 20 were systematically analysed. It was found that 16 global positioning system (GPS) models were considered valid and 12 were considered reliable for measuring intense running and/or peak speed performance. Intense running performance in GPS with lower sampling rate (e.g. ≤ 5 Hz) acquisition demonstrated reduced validity and reliability in nonlinear movement patterns as well as movement intensity increases. Some limitations of the evidence, including the conditions associated with exercise testing and the benchmark and device used, varied between studies. In addition, the data of the algorithms used by GPS can affect the interpretation of the results. Thus it would be advisable to use higher sampling rates.

- 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.
- Variability of gross and fine motor control in different tasks in fibromyalgia patientsPublication . Brígida, Nancy; Catela, David; Mercê, Cristiana; Branco, Marco A. C.Fibromyalgia (FM) is normally defined as a widespread pain syndrome or disease that presents disturbances in gross and fine motor control. As a gross motor control skill, gait requires coordination, balance, and muscle strength, and it could be an essential factor for FM patients to perform daily activities. Measuring the spatial and temporal gait parameters or gait variability has been used to assess motor pathologies and identify gait disorders. The Lyapunov exponent is a non-linear measure of variability, which quantifies the ability that the system has to attenuate small perturbances, indicating thatthere might be a relationship between balance and spati-otemporal gait parameters. This technique has already been used for gait analysis and could be used in fine and gross daily tasks, such as the finger tapping test (FTT) or the sit-and-stand test. Inertial Measurement Units have also been used to analyze gross motor control, namely in gait variability. So, the aim of this study is to analyze and compare the variability of gross and fine motor movements between patients with FM and a control group. The sample included 20 female participants, 10 with FM and 10 without (46.150 ± 12.835 years old). To analyze gross motricity, participants were asked to perform the gait task for two minutes and the 30-second chair sit-and-stand test; and to analyze fine motor control, they were asked to perform six trials of FTT test with both hands. To collect the data, an inertial sensor (IMU) was used. FM patients showed a more irregular pattern of linear acceleration peaks than controls in both tasks. Lyapunov values in FM patients show greater instability and variability in the anteroposterior and vertical movements for gait analysis and present significantly higher variability in the anteroposterior movements when performing the sit and stand task and the finger tapping test.
