Título: Diagnóstico Repetido de COVID-19: Influência da Modulação Automática e Capacidade Funcional de Pessoas Idosas Autor: MIRANDA, Thamyres da Cruz Primeiro orientador: PIRES, Flávio de Oliveira Abstract: Objective: To analyze the influence of the number of times of diagnosis of covid-19 on autonomic modulation and functional capacity in the older people. Materials and methods: This is a quantitative cross-sectional study, which included 38 without covid-19 (Control), 25 who had covid-19 once (C1), and 16 infected with covid-19 two or more times (C2+). Anamnesis, anthropometry, blood pressure collection, 6-minute walk test, Time Up and Go and resting electrocardiogram were performed. Data were analyzed by Kolmogorov-Smirnov, followed by 1-way ANOVA and Tukey-Kramer Multiple Comparisons Test, with significance for p≤0.05. Results: No differences were found between age, Body Mass Index, systolic and diastolic blood pressure. In terms of autonomic variables, there was a reduction in NN intervals (p=0.04) when comparing C1 and C2+, an increase in LF/HF when comparing C2+ to the control group and C1 (p=0.02), a reduction in SD2 (p=0.01) between C1 and C2+ when compared to the control group, and a reduction in Alpha 1 when comparing the control group to the C1 and C2+ groups (p=0.001). Conclusion: It is suggestive that individuals with a higher number of reinfections may be subject to reduced Heart Rate Variability and increased cardiac autonomic dysfunction. We did not observe statistical difference for (6MWT) and (TUG) between the groups. Instituição: Universidade Federal do Maranhão Tipo do documento: Dissertação

Título: Análise de desempenho e ansiedade pré-competitiva em jogadores de futsal participantes dos jogos estudantis do Instituto Federal do Maranhão etapa estadual Autor: DUTRA, Fábio Henrique França Primeiro orientador: NAVARRO, Antonio Coppi Abstract: Objective: To investigate the technical performance, pre-competitive anxiety levels (somatic and cognitive), and self-confidence of school futsal players participating in the State-level Student Games of the Federal Institute of Maranhão (JIFMA), held in São Luís, Maranhão, Brazil. Materials and Methods: This was a cross-sectional, descriptive and analytical study with a quantitative approach. Participants were 22 male school futsal players, aged 15 to 19 years, belonging to the finalist teams (Polo 3 and Polo 4) of the state stage of the IFMA Student Games (JIFMA) 2024, held in São Luís, Maranhão, Brazil. The sample was selected by convenience. Data collection took place at the competition venue, 30 minutes before the matches. Pre-competitive anxiety was assessed using the Competitive State Anxiety Inventory-2 (CSAI-2), encompassing cognitive, somatic anxiety and self-confidence, while technical performance was obtained through recording and analysis of the games, quantifying passes, shots, and ball possession time. Players who participated in all matches and fully responded to the instruments were included; those absent from one of the games or with incomplete questionnaires were excluded. The data were analyzed using descriptive statistics (mean and standard deviation) and inferential statistics, applying the Shapiro-Wilk normality test. The Student's t-test for paired samples (parametric data) and the Wilcoxon W test (non-parametric data) were used, adopting p<0.05. The study was approved by the Research Ethics Committee of the University Hospital of the Federal University of Maranhão (opinion no. 3.443.502), in accordance with Resolution no. 466/12 of the National Health Council. Results: Regarding technical performance, Polo 3 showed significant variations in passing and finishing throughout the competition (p<0.05), especially in the 2 vs. 3 and 3 vs. final matches, while Polo 4 demonstrated greater stability, with a significant difference only in passing (p<0.05) in the 2 vs. 3 match, without changes in the other variables. Cognitive and somatic anxiety remained low and without significant differences (p>0.05), while self confidence varied significantly throughout the games. Conclusion: The findings indicate variations in technical performance throughout the competition, with improvements in offensive actions (passing and finishing), reinforcing the need for continuous training. Self-confidence stood out as the main variable observed, while cognitive and somatic anxiety remained low and stable. Instituição: Universidade Federal do Maranhão Tipo do documento: Dissertação

Saúde mental e comportamento físico: prevalência de ansiedade, depressão e estresse e sua relação com o nível de atividade física em universitários de Educação Física da UFMA

Título: Saúde mental e comportamento físico: prevalência de ansiedade, depressão e estresse e sua relação com o nível de atividade física em universitários de Educação Física da UFMA Autor: NASCIMENTO, Kleidiane dos Santos Primeiro orientador: NAVARRO, Francisco Abstract: Objective:The present study aimed to analyze the prevalence of depression, anxiety, and stress symptoms among undergraduate students in Physical Education at the Federal University of Maranhão (UFMA), and to investigate the association of these symptoms with the levels of physical activity in the sample. Materials and Methods:This is an epidemiological, observational, and cross-sectional study. The target population consisted of undergraduate students in Physical Education at UFMA, with a minimum calculated sample of 225 participants. Data collection employed an electronic questionnaire composed of three validated instruments: Socioeconomic Stratification Questionnaire (ABEP): For economic classification. International Physical Activity Questionnaire (IPAQ – Short Form): For classification of the level of physical activity. Depression, Anxiety and Stress Scale (DASS-21): For screening mental health symptoms. Statistical analysis included descriptive and inferential statistics. The association between the level of physical activity and the symptoms (DASS-21) was tested using Fisher's Exact Test, with a significance level set at p < 0.05. The study received ethical approval (CAAE 64678022.9.0000.5087). Results: The final sample consisted of 225 students (138 male and 87 female). An alarming paradox regarding physical activity habits was identified: the prevalence of physical inactivity (sedentary + insufficiently active) was 71.8% in men and 61.6% in women. Regarding mental health, a clear gender disparity was observed, with women presenting significantly higher frequencies and more severe cases of psychological distress, especially in Stress (66.7% general prevalence) and Anxiety (62.1%). Among men, Anxiety was also the predominant symptom (42%), while Stress remained mostly at normal levels. Severe/extreme Depression affected both groups similarly (~17%). Inferential analysis confirmed a statistically significant association ($p<0.05$) between sedentary behavior and worse mental health outcomes, indicating that inactive students exhibit higher anxiety and depression scores. Conclusion: It is concluded that Physical Education students at UFMA experience an academic contradiction, characterized by high rates of sedentary behavior and psychological distress, demystifying the image of these students as inherently active and healthy. The study highlighted distinct vulnerability profiles: men present a greater risk associated with physical inactivity, while women suffer from acute emotional overload (anxiety and stress). The confirmed association between sedentary behavior and poorer mental health outcomes suggests that theoretical training is not ensuring self-care, demanding urgent institutional interventions for psychopedagogical support and the promotion of sports practice within the undergraduate curriculum itself.

Título: Efeito de uma sessão aguda de exercício físico aeróbio e resistido sob os níveis plasmáticos de marcadores hormonais Autor: JACINTO, Angélica Gomes Primeiro orientador: NASCIMENTO, Marcos Antonio do Abstract: Objective: The aim of this study was to investigate the effect of an acute session of aerobic and resistance exercise on plasma leptin and insulin levels in patients with Chronic Kidney Disease (CKD) undergoing conservative treatment. Materials and Methods: This is a randomized crossover clinical trial with 18 patients with chronic kidney disease undergoing conservative treatment (40-60 years old), conducted at the Center for the Prevention of Kidney Diseases (CPDR). Each participant performed three sessions: control (no exercise), aerobic exercise, and resistance exercise, acting as their own control. The study was approved by the ethics committee of the State University of Maranhão (UEMA); and all volunteers consented to participate. Body composition and serum leptin and insulin levels were assessed by tetrapolar bioimpedance and ELISA, respectively. Aerobic exercise was performed on a cycle ergometer (27 min; Borg 7–14), and resistance training included eight exercises (five for upper limbs and three for lower limbs), two sets of 10 repetitions at 60–70% of submaximal load. Statistical analysis was conducted using JAMOVI software (v.2.6.44), with a significance level of 5%, applying normality tests, ANOVA for repeated measures, and calculation of effect size (Cohen's D). Results: Acute sessions of aerobic and resistance exercise did not promote significant changes in serum leptin levels. However, only the comparison of serum insulin values between baseline and after strength training showed statistical significance (p = 0.0268), with a large effect size. Insulin correlated positively with weight (r = 0.288), height (r = 0.376), lean mass (r = 0.316), and extracellular water (r = 0.316), while leptin showed a positive correlation with Body Mass Index (BMI) (r = 0.402) and a negative correlation with height (r = -0.393). Conclusion: It is concluded that a session of aerobic or resistance exercise does not significantly alter hormonal or body parameters in patients with Chronic Kidney Disease, possibly due to the low intensity of the exercise and the small sample size.
