Item Acesso aberto (Open Access) Aspectos motores, funcionais e emocionais de indivíduos com sintomas vestibulares(Universidade Federal do Pará, 2024-03-01) MONTEIRO, Luiz Humberto Figueiredo; MORAES, Suellen Alessandra Soares de; http://lattes.cnpq.br/6278397231382779Individuals with vestibular symptoms present unstable gait, imbalance and one way to measure an individual's level of imbalance is through baropodometry, widely used in clinical practice to map the area of plantar pressure through graphic records and determine displacements and oscillations. of the center of pressure through stabilometry. Furthermore, balance and anxiety are related, as they share the same central neural circuits. Thus, psychological complaints such as anxiety and depression are common in individuals with dizziness. Therefore, the present study aims to analyze the motor, functional and emotional characteristics of individuals with vestibular symptoms. The analysis of plantar pressure and center of pressure was carried out using baropodometry and stabilometry on a force platform (BaroScan®, Londrina, Paraná, Brazil) and the BaroSys software, while for functional analysis we used the TUG test and the aspect functional of the DHI questionnaire and for emotional analysis the emotional aspect of the DHI. We found that individuals with vestibular symptoms have flat feet, with higher values of maximum pressure, mean pressure, maximum pressure in the midfoot and rearfoot and mean pressure in the rearfoot when compared to people without vestibular symptoms. Furthermore, individuals with vestibular symptoms have reduced functional mobility and a greater risk of falling, in addition to having compromised emotional and mental health, with signs of anxiety and mild to moderate depressive symptoms in the majority of individuals when compared to individuals without vestibular symptoms.Item Acesso aberto (Open Access) Características do ambiente escolar associadas à prática de educação física e ao deslocamento ativo em adolescentes de Belém-PA: um estudo multinível(Universidade Federal do Pará, 2025-02-26) SOUZA, Naicha Stefanie Félix; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; https://orcid.org/0000-0003-4683-9576Understanding how school environment characteristics influence adolescent physical activity behaviors is essential for developing targeted interventions. The aim of this study was to investigate the associations between school environment characteristics and the levels of participation in Physical Education (PE) classes and active commuting to school. This is a cross sectional study with multistage sampling, involving 1,719 adolescents from 46 public and private high schools in the municipality of Belém, Pará. The time spent in PE classes and active commuting during the previous week was self-reported based on the National School Health Survey questionnaire. School environment characteristics were obtained through questionnaires completed by school administrators and researcher observation visits. Zero-inflated negative binomial regression models were used to address overdispersion and excess zeros in the data. The results indicated that the majority of students (55.0%) did not participate in practical PE classes, with only 37.6% reporting 30 minutes or more of activity per week. Regarding active commuting, approximately one-third of adolescents (34.6%) did not engage in this type of commuting. In the logit component of the adjusted models, factors associated with reduced odds of non-participation in PE classes included a higher number of PE teachers (OR = 0.79; 95% CI: 0.71–0.87), the presence of locker rooms (OR = 0.66; 95% CI: 0.54–0.83), and school accessibility (OR = 0.68; 95% CI: 0.54–0.86). For active commuting, the presence of sidewalks (OR = 1.34; 95% CI: 1.03–1.74) and bike racks (OR = 1.61; 95% CI: 1.26–2.05) increased the odds of non-engagement, while speed bumps (OR = 0.60; 95% CI: 0.43–0.82) reduced the odds of non-engagement. In conclusion, school environment characteristics have the potential to decrease non-adherence to practical PE classes among adolescents. However, active commuting behaviors may depend on factors beyond infrastructure, requiring further exploration.Item Acesso aberto (Open Access) A intervenção em dupla-tarefa protege do declínio associado à idade nas atividades em dupla-tarefa(Universidade Federal do Pará, 2023-04-18) PONTES, Helen Tatiane Santos; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211XIntroduction: Older adult’s functionality is related to the ability to divide attention into daily life multitasking activities. The ability to coordinate attention in motor and cognitive activities performed simultaneously decreases with aging, compromising functional ability, and therefore older adults' participation and healthy aging. Objectives: The main objective of the present study is to evaluate the effects of a multimodal physical exercise intervention protocol, at moderate intensity, simultaneously with cognitive stimulation (dual-task) on the dual task cost in healthy community-dwelling older adults. Methods: 70 older adults, with no cognitive disfunction participated in the study. Participants were grouped into a Dual Task Exercise group (DTEx, n=40) who performed the intervention protocol of 24 sessions, twice a week, for 75 minutes, and a control group (CG, n=30) who received information on health education and did not perform physical exercises. Two-way mixed ANOVA was used for dual-task cost analysis and Bonferroni tests were used as post-hoc for within-group and between-group comparisons. The project was registered in the Brazilian Registry of Clinical Trials (UTN code: U1111-1233 6349) and approved by the Research Ethics Committee of the Institute of Health Sciences of the Federal University of Pará (CAAE no. 03427318.3.0000.0018). Results: There was Group x Time interaction (F (1.68) = 7.207 p ≤ 0.009, η2 p = 0.096) observed for the performance of the motor component of the dual task cost. The DTEx group showed maintenance of the gait speed as the motor component of the dual task cost (Assessment = -11.4% ± 3.0; Reassessment = 10.2% ± -2.6, p = 0.665) while the CG showed an increased cost of approximately 49.76% (Assessment: -10.4% ± 3.4; Reassessment: -20.9% ± 3.0 p ≤ 0.002). Significant differences were found on the performance of the motor component of the cost of the dual task between the groups in the post-intervention condition (GC Reassessment: -20.9 ± 3.0. Reassessment DTEx = -10.2% ± -2.6, p ≤ 0.011). No main effects were observed in the assessment of the cost of the cognitive component. Conclusions: The results suggest that moderate-intensity multimodal physical exercise associated with dual-task cognitive stimulation attenuated the decline in the dual-task cost in the older adults. The cost of dual task is an important clinical measure to assess the functional and cognitive ability to perform tasks of daily living in aging.Item Acesso aberto (Open Access) Predição da massa livre de gordura e do índice de massa muscular por impedancia bioelétrica em homens com tetraplegia fisicamente ativos(Universidade Federal do Pará, 2022-05-25) VIEIRA, Andreia Bauermann; KOURY, Josely Correa; http://lattes.cnpq.br/9039270525512042; https://orcid.org/0000-0002-3189-9261; SILVA, Anselmo de Athayde Costa e; http://lattes.cnpq.br/4794918582092514; https://orcid.org/0000-0001-5265-619XIndividuals with cervical spinal cord injury (c-SCI) experience progressive loss of fat-free mass (FFM) due to decreased physical activity and neurological impairments because the function of spinal neuronal circuits below the level of injury is impaired. Therefore, there is a reduction in muscle strength and physical performance, characterizing sarcopenia, similar to what occurs in the elderly. The bioelectrical impedance (BIA) method is valid and accessible for predicting FFM in different population. The ground of the BIA method is based on the principle of constant hydration. However, individuals with c-SCI show important variations in hydration status, a fact that makes it difficult to use generalized predictive equations for FFM by BIA. Considering that the prediction of FFM in individuals with c-SCI is important to monitor changes in body composition and to support studies on sarcopenia, the present dissertation aims to: 1) test the agreement between the FFM values obtained by three different predictive equations by BIA and by dual-energy X-ray absorptiometry (DXA), 2) test the applicability of bioelectrical impedance vector analysis (BIVA) for this group; and 3) compare the use of the muscle mass index (SMI) from the FFM obtained by BIA and DXA for the diagnosis of sarcopenia in people with tetraplegia, considering different levels of physical activity (sedentary, active >150 minutes per week, and very active > 210 minutes per week). Able bodied individuals (n=23) and with c-SCI physically active (n=13) or inactive (n=10) participated in the study. Only the equation by Buchholz et al. showed agreement (coefficient of agreement=0.85) with DXA. Sarcopenia is a common disease after c-SCI and can be diagnosed using the SMI, which was tested in this group using the suggested equations for BIA and DXA. The use of the SMI-BIA to classify sarcopenia in sedentary c-SCI individuals resulted in substantial diagnostic agreement (Kappa=0.727) according to the Kappa coefficient. Buchholz et al. equation presented the best agreement, but this was not enough for this equation to be recommended for use in people with c-SCI and a specific equation for this population should be created. However, the use of cut-off points to diagnose sarcopenia from the SMI-BIA seems promising in sedentary people with c-SCI, necessitating further studies in people with c SCI that are physically active.
