  • Predictive Factors of Mental Health in Athletes from the Paralympic Preparation Program During Social Isolation: The Role of Sleep, Competitive Status, and Motivation
    Publication . Eduarda Coelho; Carla Lourenço; Pereira, Antonino; Maria Isabel Mourão-Carvalhal; Sandra Fonseca
    Background: The COVID-19 pandemic posed unprecedented challenges for elite athletes, disrupting training routines and affecting mental health. This study examined the impact of social isolation on training, sleep, motivation, and psychological well-being among Portuguese Paralympic athletes. Methods: Forty-five athletes (31.36 ± 10.81 years) from the Paralympic Preparation Program participated, divided into the Paralympic Preparation Project (PPP; n = 21) and the Paralympic Hopes and Talents Project (PHTP; n = 24). Training routines before and during social isolation were compared. Sleep duration, training motivation, and mental health were assessed using the Mental Health Inventory-5 (MHI-5). The analysis employed paired and independent t-tests and a multiple linear regression (Enter method) to examine predictors of mental health. Results: Daily training duration declined by 34.3% (p < 0.001), though weekly frequency remained stable (p = 0.061). PPP athletes reported higher mental health scores than PHTP athletes (66.24 vs. 60.37; p = 0.048). The regression model explained 42.8% of the variance in mental health (R2 = 0.428). Sleep duration was positively associated with mental health and showed the highest standardized coefficient in the regression (β = 0.351; p = 0.008), followed by PPP status (β = 0.315; p = 0.024) and motivation (β = 0.278; p = 0.041). Conclusions: Maintaining biological routines, particularly sleep and motivation, supports mental health under social isolation. Higher well-being among PPP athletes underscores the need for targeted interventions for less experienced athletes. Sports organizations should prioritize sleep hygiene and psychological support to mitigate vulnerability during crises.
  • Timeout as a strategic tool in Handball: Decision-making and performance processes’ analysis
    Publication . Nunes, Tomas; Azevedo, António; Mendes Ribeiro Eira, Paulo Alexandre
    Timeout in Handball serves as a strategic intervention that allows coaches to manage game dynamics and make real-time adjustments in order to enhance their team’s performance. The present study aimed to analyze the timeout as a strategic tool in Handball, investigating the factors that lead to its use, the content of the coach's speech during the break, and its effects on team performance. The study group consisted of four Portuguese male coaches, all holding the Sports Coach’s professional title – Level IV (Master Coach), with over ten years of experience. Their interventions were observed in 124 timeouts recorded during national competitions in U16, U18, and Senior categories. The interventions were recorded using a validated observation grid, complemented by semi-structured interviews subjected to content analysis, with the aim of understanding the communicational intentions and perceptions regarding the intervention’s effectiveness. The results reveal a predominance of tactical statements, followed by psychological and technical content. It was found that discourse is adapted to the competitive context: in youth categories, it assumes a pedagogical and motivational character, while at highperformance level it becomes more directive and focused on strategic details. Communication’s clarity, brevity, and objectivity, as well as the use of visual aids, emerge as key determinants of timeout effectiveness. The timeout is characterized as an essential tool for technical-tactical and emotional regulation, whose effectiveness depends on time management, discourse coherence, and suitability to the competitive level. It is recommended to implement communication specific training programs applied to coaching and to deepen research that relates the interventions’ content to objective performance indicators.

Conclusão: A aprendizagem através de exercícios lúdicos que garantam e aumentem a segurança das crianças no meio aquático é crucial, fundada num processo estruturado e pedagogicamente adequado às suas necessidades.
  • Individual and Joint Associations of Cancer Diagnosis and Handgrip Strength with Depression in European Middle-Aged and Older Adults
    Publication . Vasconcelos, Carlos; Miguel Peralta; Adilson Marques
    : Depression is a mood disorder affecting millions of people worldwide and is especially prevalent in older ages. There are a multitude of interconnected factors that influence depression, including cancer and handgrip strength. In this study, we sought to understand how these two factors, cancer diagnosis and handgrip strength, are individually and jointly associated with depression. For that, we conducted an analysis with depression evaluated in 2017 and 2019 in a large sample of European middle-aged and older adults. Both cancer and handgrip strength were associated with depression, with the first increasing its risk and the later reducing it. A joint association pattern was also found, where individuals with greater handgrip strength and no cancer had a lower risk of depression. Campaigns aimed at cancer prevention and participation in exercise programs, with an emphasis on resistance training, should be encouraged
  • Effects of Combined Interventions of Physical Activity and Diet in Childhood Cancer Survivors: A Systematic Review
    Publication . Vasconcelos, Carlos; Sousa, Patrícia
    Physical activity and diet have complementary benefits for attenuating adverse health effects that childhood cancer survivors experience after the end of treatment. This review aimed to explore the impact of combined physical activity and diet interventions on the health status of childhood cancer survivors. A thorough review of the literature was carried out using the Cochrane Library, PubMed, Scielo, LILACS and Web of Science databases for studies published until June 2024. Studies concerning survivors of childhood cancer of any type engaged exclusively in combined diet/physical activity interventions were included in this review. Three manuscripts met the inclusion criteria. The results indicated that combined physical activity plus diet interventions showed beneficial impacts for the intestinal microbiome, percentage of calories from sweet foods, daily consumption of sugary beverages, reduction in sedentary activity, and mood (1 out of 1 study for each of the presented outcomes). Although more rigorous studies are needed, these findings showed promising results regarding the impact of interventions involving both physical activity and diet on childhood cancer survivors

  • Fear of the Aquatic Environment in Learning Swimming: Causes, Effects, and Learning Methodologies
    Publication . Diana Grandão; Mendes Ribeiro Eira, Paulo Alexandre; Azevedo, António
    In the swimming context, practitioners show difficulties in learning its basic skills, and the emotional factor seems to be one of the triggers for these complications, with “fear” standing out as one of the most studied emotions due to its cognitive reactive nature associated with survival mechanisms. This emotional response can hinder the learning process in swimming, potentially leading to disengagement or dropout. The present study aimed to analyze the causes that lead to fear of the aquatic environment, its effects on learning swimming, and how swimming coaches can intervene to help overcome this fear. Direct observation was used to capture the individuals’ perception of the degree of fear. Subsequently, semi-structured interviews were conducted to analyze an intervention aimed at reducing the fear of water, followed by a corresponding content analysis. The fear of water is commonly associated with anxiety, panic, and muscle tension. The role of the swimming instructor is crucial, as their teaching approach significantly influences the swimmer’s emotional response, particularly in fostering a sense of security. The use of playful activities proves effective in helping children adapt, overcoming the limitations posed by the fear of water. Recognizing students’ fears allows instructors to structure swimming lessons effectively, helping students overcome their emotional barriers. Therefore, introducing children to the aquatic environment at an early age contributes to this goal
