- Quantification of Maximal Force Produced in Standard and Contra-Standard Sculling in Synchronized Swimming. A Pilot StudyPublication . Diogo, V.; Soares, S.; Tourino, C.; Carmo, C.; Aleixo, I.; Morouço, P.; Figueiredo, P.; Vilas-Boas, J. P.; Fernandes, R. J.Studies carried out in synchronized swimming are very scarce, namely those which include biomechanical analysis of the sculling technique. The purpose of this study was to measure the maximal force produced in standard and contra-standard sculling, using a 30s maximal tethered synchronized swimming test. One former female synchronized swimmer and one former female swimmer performed a 2x30s maximum intensity tethered synchronized swimming test, in standard and contra-standard sculling conditions, respectively. Parameters studied were maximal, mean and minimum force, the time when maximal and minimum force occurred, and fatigue index. Results showed that the higher values of maximal and mean force were found in standard sculling, both for the synchronized swimmer and the swimmer. The swimmer attained higher values of absolute and relative maximal force in the standard sculling, but lower values in the contra-standard technique, when compared to the synchronized swimmer. Fatigue Index results evidence that the maximal force declined during the 30s in both participants and in both sculling conditions. This parameter was higher for the contra-standard sculling performed by the swimmer, and for the standard sculling for the synchronized swimmer. In conclusion, there were differences in force production in standard and contra-standard sculling between a swimmer and a synchronized swimming. Those differences could probably be explained by differences in skill competence.

- Biomechanical and bioenergetical evaluation of swimmers using fully-tethered swimming: A qualitative reviewPublication . Amado, Nuno M.; Morouço, Pedro, G.; Marques, Mário C.; Fernandes, Ricardo J.; Marinho, Daniel A.It is presented a qualitative review of the specialized literature on fully-tethered swimming, with the scopes of summarizing and highlighting published knowledge, identifying its gaps and limitations, and motivate future research. The major research conclusions can be summarized as follows: (i) tethered swimming is a reliable test to evaluate force exerted in water by swimmers; (ii) higher maximum values of force are obtained in breaststroke and butterfly, while average values are higher in front crawl; (iii) tethered forces present moderate to strong relationships with swimming velocity, and associations between forces diminish as swimming distance increases; (iv) 30 s maximal tethered swimming may be used as an adaptation of Wingate test for swimming; (v) differences in stroke mechanics can occur in tethered swimming but there is no evidence to suggest that they affect swimming performance; (vi) Tethered swimming is a valid methodology to evaluate aerobic energy contribution in swimming and recent investigations concluded that it can also provide information on the anaerobic contribution. Based on and stimulated by current knowledge, further research should focus on the following topics: (i) the usefulness of tethered swimming as a valid tool to evaluate other swimming techniques; (ii) differences in force parameters induced by gender or competitive level; (iii) defining accurate variables for estimation of anaerobic power and/or capacity using tethered swimming; (iv) bilateral asymmetries in exerted forces, and corresponding influence of breathing; (v) relative contribution of arms and legs for whole-body propelling forces
- Influence of Postural Intervention During the Sleep Period on Back Pain, Quality of Life and Sleep Quality in Young AdultsPublication . Desouzart, Gustavo; Filgueiras, Ernesto; Matos, RuiHuman health may have several problems that occur when sleep disturbances are verified, causing a loss in the quality of life, autonomic dysfunction and decreased professional or academic performance. Objective: The aim is check if the ergonomic intervention can mean positive changes in the indices of back pain (BP) complains, quality of life (QOL) and sleep quality (SQ) in young adults. Methods: A sample of 21,560 observations (595 sleep hours) of 24 young adults (12 male military and 12 female undergraduate) were separated in three groups (Experimental [EG], Placebo [PG] and Control [CG]). The sleep behavior was classified into two Interaction Categories according to the iSEE methodology observation. For the carrying out, the Visual Analogue Scale, the abbreviated questionnaire of World Health Organization on quality of life and the Pittsburgh Sleep Quality Index was used before and after an ergonomic intervention program by physiotherapy. Results: EG improved self-perception of SQ (p = 0.008), QOL (p = 0.000), reduce the level of BP (p = 0.001) and change for an ideal posture while sleeping. Conclusion: The findings of this study allow us to suggest to health care professionals, in particular the rehabilitation professionals, new strategies for ergonomic postural behavior.

- Comparison of force variables and dynamic strength index between age groups in elite young Brazilian football goalkeepersPublication . Portella, Daniel Leite; Jatene, Pedro; Da Silva, Alex O.; dos Santos, Gustavo S.; Monteiro, Diogo; Teixeira, José E.; Branquinho, Luís; Ferraz, Ricardo; Forte, PedroIntroduction: The application of muscle force is a determinant of football success as it is inherent to the motor control and sport. The aims of this study are: (1) to describe force variables Isometric Maximal Force (IMF), Concentric Peak Force (CPPF), and Dynamic Strength Index (DSI) in football goalkeepers from different age groups; (2) to compare these variables’ behavior between those groups. Methods: The sample was formed by 19 youth players (15.97 ± 1.55 years old) from a first-division Brazilian football team. The CPPF and IMF variables were obtained through the Countermovement jump and isometric squat tests, respectively. For data collection, a force plate (Cefise, Brazil) was used with an acquisition frequency of 600 Hz and mono-axial. The DSI was calculated using the ratio between CPPF and IMF. For data analysis, the sample was separated into clusters by age. After the grouping, a descriptive analysis of the data and a comparison between the groups with p < 0.05. Results: The sample was grouped into three groups (GA, GB, and GC) and one of the individuals did not enter the group, totaling 18 individuals in the analyzed sample. The comparison between the ages of the groups showed a significant difference and small and moderate effect size (ES), validating the cluster strategy. The CPPF and IMF variables showed increased values according to chronological age. CPPF showed a significant difference between GA-GB, (ES = very large) GA-GC (ES = very large), and GB-GC (ES = moderate). The IMF variable had significant differences between GA-GB (ES = moderate) and GA-GC (ES = very large). However, DSI showed significant differences only between GA GB (ES = small) and GB-GC (ES = very large). Conclusions: The CPPF and IMF variables had constant increases and distinct values with an increase according to age, and this did not occur for DSI. The difference between CPPF and IMF compared to DSI bring to light the variability in dynamics and proportionality between muscular force in the concentric phase and maximal force in the isometric regime during the developmental process over chronological age in soccer goalkeepers.
- Efeitos de um programa de exercícios na autonomia, independência e aptidão física de pessoas com deficiência intelectual e de desenvolvimento - Um estudo pilotoPublication . Tomé, Alexandra; Antunes, Raul; Monteiro, Diogo; Matos, Rui; Rodrigues, Filipe; Amaro, Nuno; Jacinto, MiguelThe literature clearly highlights the relationship between the levels of autonomy and independence of people with intellec-tual and developmental disabilities (IDD) and their levels of physical fitness. Thus, the aim of this study was to analyze the effectsof a physical exercise program on the levels of autonomy, functionality in activities of daily living (ADL), and physical fitness of people with IDD. 17 participants completed the 9-week intervention, where parameters such as anthropometric data (height, weight, body mass index (BMI) and muscular mass (MM)), functionality in ADL (WHODAS 2.0) and data regarding physical fitness (handgrip test, Sit and Stand and timed up and go) before and after the intervention were evaluated. Significant improvements were found after the physical exercise intervention program in the functionality (self-reports: t=-2.19; p=0.03; η2=0,282and proxy reports: t=-2.64; p=0.01; η2=0,410) and body composition variables (BMI: t=-2.08; p=0.05; η2=0,254 and muscle mass;t=-1.94; p=0.05; η2=0,221), but not in the physical fitness variables. The intervention program seems to have contributed positively to improvingthe perception of autonomy in ADLs and body composition.
- Physical Activity, Quality of Live and Well-Being in Individuals with Intellectual and Developmental DisabilityPublication . Diz, Susana; Jacinto, Miguel; Costa, Aldo M.; Monteiro, Diogo; Matos, Rui; Antunes, RaulThe practice of physical activity, exercise and sport has many benefits for the general population, but studies on the population with intellectual and developmental disabilities (IDD) are scarce and inconclusive. The aim of this systematic review is to analyze the state of the art on the role of physical activity, exercise and sport in the quality of life and well-being of people with IDD, seeking to understand the current panorama in this area and provide answers to these questions. The research was carried out between July and October 2023 using three databases: PubMed, Web of Science and Scopus. Fifteen articles met the eligibility criteria for this study, and these were methodologically assessed using the Downs and Black scale (1998). Higher values were identified in the total quality of life score and some domains of this variable (e.g., personal development, physical well-being and emotional well-being), in satisfaction with life and in the perception of well-being in individuals with IDD who have enjoyed or are involved in physical activity, physical exercise and/or sports programs. Thus, according to the studies included in this systematic review, we can conclude that the practice of physical activity, physical exercise and sport seems to contribute to improving the quality of life and well-being of people with IDD. Despite the growing research interest in this area, there is still a notable lack of studies exploring the impact of these programs, especially sports-based programs, on quality of life and well-being variables in the population under study.

- Exploring the relationship across autonomous motivation, affects, and anxiety among gym practitioners during the second COVID-19 lockdownPublication . Antunes, Raul; Rodrigues, Filipe; Jacinto, Miguel; Amaro, Nuno; Matos, Rui; Monteiro, DiogoThe present study explores the association of autonomous motivation and the relationship of positive and negative affect on anxiety levels among individuals engaged in gym practitioners during the second COVID-19 lockdown. A total of 196 exercisers (29.17 ± 10.77) were enrolled in the present study, of which 112 (57.1%) were women and 84 (42.9%) were men. The survey included sociodemographic data, as well as validated instruments measuring autonomous motivation, positive and negative affect, and anxiety states related to the COVID-19 pandemic. The results revealed a positive association between autonomous motivation and positive affect (β = 0.36, CI 0.12, 0.37; p < 0.001), and a negative association between autonomous motivation and negative affect (β = − 0.17, CI − 0.31, − 0.01; p = 0.03). Moreover positive, and negative affect are negatively (β = − 0.33, CI − 0.43, − 0.24; p < 0.001) and positively (β = 0.72, CI 0.57, 0.82; p < 0.001) associated to anxiety, respectively. Thus, this study appears to emphasize the association of autonomous motivation on affect as a potential buffer against anxiety levels, particularly in a context where practitioners found themselves restricted in their usual gym practices.
