- Body image and well-being in dance practitioners: An exploratory studyPublication . Faria, B.; Frontini, R.; Antunes, R.Literature has been concerned with the effect of dance practice on several variables, namely well-being and body image (BI). This study aimed to analyse the perception of dance practitioners on BI and subjective well-being (positive and negative affect and satisfaction with life), comparing adolescents and adults. A sample of 91 dancers (18.08±5.12 years) was recruited and divided into two groups (adolescents 11-17 years; adults 18-34 years). The group of adolescents presented a higher perception of satisfaction with life compared to adults (p=0.041; d=-0.44). Regarding the relationships between variables, when analysing separately each group, in the group of adolescents the positive affect is related to satisfaction with life (r=0.64; p≤0.001) and negative affect (r=-0.32; p=0.026), while the negative affect is related to the hours of weekly practice (r=0.46; p=0.001). In the group of adults, positive affect is related to satisfaction with life (r=0.36; p=0.017) and weekly hours of practice (r=0.39; p=0.010), while negative affect is related satisfaction with life (r=-0.45; p=0.003). With regard to (dis)satisfaction with BI, we found that, in the group of adolescents, it is related to the years of practice (r=0.33; p=0.023) and the weekly hours of practice (r=0.32; p=0.023), while in the adults' group, satisfaction with life (r=-0.42; p=0.005) and negative affect (r=0.59; p≤0.001) are related. Our results leave some indicators that should be explored in future studies, namely seeking to understand the factors that may be mediating the relationship between BI and well-being, as well as the effect of age on this relationship.
- Dispositional Orientations in Competitive Ultimate Frisbee AthletesPublication . Amoroso, J.; Antunes, R.; Valente-dos-Santos, J.; Furtado, G.; Rebelo-Goncalves, R.The purpose of this study to analyze dispositional orientations among Ultimate Frisbee (UF) athletes according to different divisions. Data was collected during the European Beach Ultimate Championship (EBUC) 2019. The sample comprised a total of 484 athletes (34.7±9.7 years of age), from 19 countries. Participants were asked to fill in a sociodemographic questionnaire, and the Perception of Success Questionnaire (POSQ). Participants were grouped in eight competitive divisions: Mixed (n=123), Grand master men’s (n=61), Master mixed (n=59), Master men’s (n=57), Great grand master men’s (n=52), Master women’s (n=51), Men’s (n=50) and Women’s (n=31). The POSQ demonstrated a reasonable internal consistency, with the inter-item reliability coefficients ranging from 0.81 to 0.90. An analysis of Variance (ANOVA) was used to compare goal orientation by UF divisions (i.e., women’s, men’s, mixed, master women’s, master men’s, master mixed, grand master men’s, great grand master men’s). On average, UF athletes reported higher levels of perceived task orientations (4.17±0.80 vs. 3.13±0.82). Multivariate analysis of variance demonstrated that there was a significant main effect of UF division on the POSQ scores. The Women’s, Men's and Mixed presented the higher task values (4.27±0.72, 4.32±0.78, and 4.35±0.67, respectively), while the Master women´s division presented the highest ego score (3.61±0.71). Our findings indicated that success among UF athletes is defined in self-referenced terms, such as through mastering tasks or improving one´s own personal skills. Further studies are necessary to understand the dispositional orientation between athletes of different divisions, since there are a variety of environmental and social variables that can be promoted and influence the observed differences.

- Load and psychophysiological responses in high-intensity interval training with fixed and self-selected recoveryPublication . Sant’Ana, Leandro; Macedo Vianna, Jeferson; Rodrigues Scartoni, Fabiana; Tolomeu de Oliveira, Géssyca; Macedo Carvalho, Bruna; De Sena Altomar, Marconi; Teixeira, Diogo; Antunes, R.; Rodrigues, Filipe; Matos, Rui; Novaes, Jefferson da Silva; Machado, Sérgio; Monteiro, DiogoIntroduction and Objective. The study analyzed the training load in high-intensity interval training sessions with different conditions of recovery time between stimuli: fixed (1min.) and self-selected. Methods. Nineteen individuals participated in the study: 13 men and 6 women (19±1.0 years; 64.0±9.2 kg; 169±8.5 cm; 22.0±2 BMI). For the training load analysis, heart rate variability (LnRMSSD), perceived effort (PE), and mood scale BRUMS (MS) were used. LnRMSSD and MS were evaluated before and after the sessions. The PE was evaluated during each session immediately after each stimulus. The protocol was 10 x 30s (95% Vpeak) with active recovery (40% Vpeak) in fixed or self-selected time. ANOVA-RM (2 [interventions] x 2 [time points]) for LnRMSSD and MS and (2 [interventions] x 10 [time points]) for PE was used. Results. Between condition and time*condition, no differences were observed for LnRMSSD (p=.626; p=.879, respectively), PE (p=.191; p=.792, respectively), and MS (tension: p=.673; p=.463; depression: p=.867; p=.359; anger: p=.867; p=.359; vigor: p=.811; p=.778; fatigue: p=.144; p=.998; mental confusion: p=.828; p=.752, respectively). In terms of time, significant differences were observed in LnRMSSD (p<.001) and PE (1≠3-10; 2≠4-10; 3≠5-10; 4≠5-10; 5≠7-10; 6≠7-10; 7≠ 9,10; 8≠10, p<.001). In MS, there was a difference in domains of tension (p<.001), depression (p<.015), anger (p<.033), and mental confusion (p<.001). But not for vigor (p=.339) nor fatigue (p=.419), which are associated with the training load. Conclusions. However, both recovery conditions showed similar acute internal load responses. Additionally, it is suggested that recovery with self-selected time (46.70±1.6.58s) may be a recovery option in HIIT prescription.

- Portuguese adults' concerns on the return to indoor sports practice after confinement due to COVID-19 pandemic - mitigation strategies proposalsPublication . Matos, R.; Amaro, N.; Antunes, R.; Rosa, M.Objective: This study aimed to get an insight of Portuguese adult people concerns about returning to physical activity and sports practice at indoor sports facilities, after confinement due to COVID-19’ pandemic. Subsequently, an additional approach to the traditional mitigation strategies was to be proposed. Methods: A total of 173 Portuguese practitioners on indoor physical activity or sports before pandemic participated in this study. A questionnaire asking how much concerned (1 – nothing, to 5 – completely) would they be on different contexts and aspects related to this return was applied. Results: respondents were considerably concerned about this theme, especially with touching on common surfaces and proximity to others. Although considerable concerned if having to travel by public transport to the training facility, using locker rooms and with features of the sports’ practice itself, the former received the highest concerns. Additionally, we have suggested modifying some objects (or creating others) that may allow their use with body parts other than hands - an important contagion source - and exploiting the possibility of using intermediate instruments on objects and sports equipment manipulation, preventing users from touching their surfaces directly. Conclusion: touching on common surfaces and proximity to others revealed high degrees of concern on the return to indoor sports practice after confinement due to COVID-19 pandemic. Alongside the rules of personal distancing, respiratory etiquette and surfaces hygiene, it is suggested that sports practitioners, whenever possible, use alternative body parts and intermediate instruments that avoid direct contact of hands with surfaces and sport objects.
- Qualidade de vida, vitalidade e força de preensão manual em idosos praticantes de exercício físicoPublication . Antunes, R.; Fonseca, E.; Oliveira, D.; Matos, Rui; Amaro, Nuno; Morouço, P.; Coelho, Luís; Rebelo-Goncalves, R.O envelhecimento está associado a patologias crónicas, que podem ser prevenidas ou retardadas através do envolvimento em comportamentos saudáveis, como a prática regular de Exercício Físico (EF). O objetivo deste trabalho foi caracterizar a qualidade de vida, vitalidade e força de preensão manual de idosos participantes em programas comunitários de EF, bem como analisar a relação da prática de EF com estas variáveis. Recorreu-se a uma amostra composta por 81 indivíduos, 49 do sexo feminino e 32 do sexo masculino, com idades compreendidas entre os 65 e os 85 anos (72.33±5.02). Os resultados indicam-nos que os elementos do género masculino apresentavam valores superiores nas variáveis força de preensão manual (p<0.001; 𝜂!=0.510), vitalidade subjetiva (p=0.05; 𝜂!=0.005) e no domínio “intimidade” da qualidade de vida (p=0.01; 𝜂!=0.005). Relativamente à análise das relações entre as variáveis, no género feminino a força de preensão manual está relacionada com a frequência semanal (r=0.42; p=0.003), com o número de horas de prática (r=0.49; p<0.001), e com a qualidade de vida geral (r=0.35; p=0.015). Ainda no género feminino, verificamos a existência de uma regressão linear significativa da frequência de prática semanal (R2 ajustado=0.23; p<0.001) e do número de horas semanal (R2 ajustado=0.30; p<0.001), com a força de preensão manual. Já no género masculino, a força de preensão manual correlaciona-se com o número de horas de prática semanal (r=0.38; p=0.033). Já a vitalidade está relacionada com a força de preensão manual (r=0.49; p=0.004) e com a qualidade de vida geral (r=0.61; p<0.001). Parece assim evidente o papel do EF por parte desta população, bem como a inclusão do treino de força uma vez que esta variável parece estar associada a uma melhor perceção de qualidade de vida e de vitalidade pelo idoso.
