- 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.
- Motivational Orientation, Boredom and Fun in Physical Education: The Mediation Role of Self-Esteem and Motor Self-EfficacyPublication . Reigal Garrido, Rafael Enrique; Hernández-Martos, Jacobo; Monteiro, Diogo; Pérez-López, Rocío; Hernández-Mendo, Antonio; Morales-Sánchez, VerónicaAdolescents who enjoy physical education (PE) classes are more likely to be active during out-of-school hours. Similarly, achievement goal theory suggests that task-oriented motivation is associated with higher levels of reported fun during PE classes. In contrast, ego-oriented motivation has been related to boredom in class, but some self-perceptions (e.g., self-esteem or motoric self-efficacy) may modify this relationship and are important for physical activity. Our aim in this paper was to analyze the relationships between motivational orientation and fun and boredom in PE classes by assessing the mediating effects of self-esteem and self-efficacy. We surveyed 478 teenagers between 13 and 18 years of age (M = 14.57; SD = 1.15) with the Task and Ego Orientation in Sport Questionnaire (TEOSQ), the Rosenberg Self-Esteem Scale (RSE), the Motor Self-Efficacy Scale (MSES), and the Intrinsic Satisfaction in Sport Scale (SSI-EF). We used a structural equation model to evaluate relationships between these variables of interest. We found a positive relationship between ego orientation and boredom and between task orientation and fun; and we found a negative relationship between task orientation and boredom in PE classes. Importantly, we observed indirect effects from self-esteem and motoric self-efficacy in the relationships between motivational orientation and boredom and fun in PE. These results highlight the importance of students’ motivational orientations in PE classes and illustrate that self-perception of self-esteem and motoric self-efficacy can mediate these relationships.
- Motivation to learn: an international multilevel study on student autonomy and teacher emphasis on content usefulnessPublication . Moreno-Murcia, Juan Antonio; Huéscar Hernández, Elisa; León, Jaime; Fin, Gracielle; Nodari Júnior, Rudy José; Valero-Valenzuela, Alfonso; Tristán, José; Gastélum-Cuadras, Gabriel; Zueck Enríquez, María del Carmen; Vargas Vitoria, Rodrigo; Cid, Luis; Monteiro, Diogo; Teixeira, DiogoTeacher autonomy support is related to improved student learn-ing. In higher education, few studies relate classroom contextual factors, such as teacher emphasis on content usefulness, and students' motivational characteristics. The aim was to test a multilevel model about the relation between the extent of teachers’ emphasis on the usefulness of class con-tent with student autonomy, and, in turn, on motivation to learn. The par-ticipants were 3033 university students enrolled from 1st to 4th grade of Sciences of the Physical Activity and Sport, from universities in Spain (N = 602), Portugal (N = 469), Mexico (N = 1177), Chile (N = 372), and Brazil (N = 413). A multilevel structural equation model was performed, in which participants answered questions about the teacher's emphasis on the use-fulness of class content, basic psychological need for autonomy, and moti-vation to learn. At the group and individual levels, the hypothesis is that the teacher's emphasis on the usefulness of class content predict the stu-dent autonomy, in turn, student autonomy predicts student motivation to learn. Results found at the group level and at the individual level the strength of teacher emphasis on class content predicted student autonomy; student autonomy predicted student motivation to learn.
