(Universidade Federal do Pará, 2024-04-24) SANTOS, Mayara do Socorro Brito dos; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211X
Introduction: Instruments with appropriate psychometric properties are essential for ensuring the quality of assessments and reassessments in clinical practice, guiding decision-making regarding rehabilitation procedures. The Pittsburgh Fatigability Scale, originally published in English, is the only validated scale for measuring perceived fatigability in older adults. Considering the importance of this tool, it is necessary to validate its translated version into Portuguese and adapt it to the specificities of the Brazilian context. Objective: To validate the Pittsburgh Fatigability Scale Brazilian Portuguese version (PFS-Brasil) by evaluating its validity in relation to measures of physical activity, physical performance, and cognitive performance. Methodology: The scale and physical and cognitive performance tests were used to assess 121 healthy older adults residing in the community. We conducted statistical analyses of the physical and mental subscales of the PFS-Brasil, utilizing the intraclass correlation coefficient (ICC) for reliability analysis, Cronbach's alpha for internal consistency evaluation, and Spearman's correlation for convergent validity. Furthermore, we examined agreement analysis and floor and ceiling effects. The Statistical Package for Social Sciences 25.0 was used for data analysis. Results: The analyses indicated that the physical and mental subscales exhibit satisfactory test-retest reliability, with ICC values for the physical subscale (0.84; 95% CI: 0.80-0.88) and the mental subscale (0.83; 95% CI: 0.78-0.87), in addition to high internal consistency (α = 0.84 and 0.82, respectively). These values are indicative of good inter-rater reliability, revealing a low probability of random and systematic error. Bland-Altman plots demonstrated good agreement for both subscales of the PFS-Brasil. For convergent validity, the higher physical score showed a moderate association, and the higher mental score showed a weak association with lower physical performance (6-minute walk tests and the Short Physical Performance Battery (SPPB) and lower levels of physical activity (International Physical Activity Questionnaire – IPAQ). Regarding cognitive performance, there was a weak association between the higher mental score and the average accuracy on the flanker test. No ceiling effects were observed in both subscales; however, the mental subscale exhibited a floor effect (n = 24%). Conclusion: This study demonstrated that the Brazilian version of the Pittsburgh Fatigability Scale is a valid, consistent, and reliable instrument for assessing perceived fatigability in older adults.

Diminuição nas manifestações físicas e psicológicas da síndrome pré-menstrual e de seu impacto funcional através do protocolo de dose mínima
(Universidade Federal do Pará, 2024-04-08) SILVA, Eliane Aragão da; PIRES, Daniel Alvarez; http://lattes.cnpq.br/4487383675643868; https://orcid.org/0000-0003-2163-5606
Premenstrual Syndrome (PMS) is a set of more than 200 symptoms that involve behavioral factors and somatic, emotional, and cognitive symptoms that are directly related to hormonal changes that occur in the premenstrual period. Amid stressful situations experienced throughout life, strategies are needed to face and adapt to such events. How one chooses to deal with situations is characterized by coping strategies. Women with PMS use different coping strategies compared to women without PMS, making it necessary to understand which strategies are useful for dealing with premenstrual distress and which can be actively modified with methods such as physical activity. The beneficial effect of exercise on PMS symptoms is the reduction of psychological symptoms, but studies with the application of controlled, long-term protocols are still needed. Minimum dose training is like “training snacks”, with summarized training, below that is recommended by global institutions, providing physical and psychological gains to practitioners, compared to a sedentary life. The objectives of the study are: a) to analyze the effects of a minimum dose protocol of 8 weeks on the psychological symptoms of PMS, and b) to identify which coping strategies were used by women affected by PMS during a minimum dose protocol of eight weeks. After selection by inclusion criteria based on information from a Sociodemographic Questionnaire, the PMS Symptom Screening Questionnaire (Premenstrual Symptom Screening Tool - PSST), and the Physical Activity Readiness Questionnaire (PAR-Q), 33 university students were affected. by the SPM, they were referred to two groups: the Resistance Training Group (GTR), which carried out a resistance training program, and the Control Group (CG), which carried out physical tests and filled out questionnaires. Both responded to the questionnaire (Premenstrual Symptom Screening Tool - PSST) on day 1 of their cycle for two menstrual cycles and the coping strategies questionnaire (Brief Cope), given at the end of every week for two months. For data analysis, the linear mixed model was used using Restricted Maximum Likelihood (REML) with the application of the ANOVA III table and Tukey's post hoc for the analysis of PMS symptoms. To analyze coping strategies, the linear mixed model was used for each domain, with descriptive and exploratory analysis. The program used for the analysis was R Studio. The results of the analysis showed significant differences in physical and psychological manifestations, in the second moment, with a reduction in symptoms in the GTR compared to the CG. Differences were also noticed in the functional impacts of symptoms, in the second moment, with a reduction in impacts in the GTR compared to the CG. In the coping analysis, constancy was observed in the choice of strategies, demonstrating that it was not influenced by the minimum dose protocol. We conclude that the practice of resistance training with the minimum dose method helps in the treatment of PMS symptoms by reducing physical and psychological manifestations as well as the functional impact of the symptoms on the lives of those affected. The chosen coping strategies seem to remain constant, not being influenced by the minimum dose protocol.

(Universidade Federal do Pará, 2023-03-01) MALAQUIAS, Lorenna Costa; MAGALHÃES, Maurício Oliveira; http://lattes.cnpq.br/7766377002832983; https://orcid.org/0000-0002-7857-021X
Objective: to systematically examine the clinical properties of the Spinal Appearance Questionnaire (SAQ) in its cross-cultural adaptations in different languages. Methods: The databases Medline (PubMed), CINAHL, EMBASE, Science Direct, PsycINFO and WorldWideScience.org. Used for screening studies until July 16, 2022. Records on the development, evaluation and translations of the SAQ instrument with adolescents in idiopathic scoliosis were included in this review. In addition, two reviewers defined whether the studies were eligible, as well as analyzed their psychometric properties of Internal Consistency, Reliability, Content Validity, Cross-cultural Validity, Construct Validity and Structural Validity, according to Consensus-based Standards for the Selection of health Measurement Instruments (COSMIN). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE), recommendation of modified quality classification was applied for evidence synthesis. Results: 95 articles were selected by title and abstract. After the removal of duplicates, complete reading and search in the references, there were 13 studies in this review. The original version of the SAQ was described in English and its analysis was made in 2 articles and the instrument was translated into Polish, Canadian French, Simple Chinese, Spanish (Europe), Danish, Traditional Chinese, Portuguese (Brazil), Korean, German, Turkish and Persian. The evidence was moderate for construct validity, low for internal consistency, very low for reliability and cross-cultural validity; the properties of content and structural validity did not present minimum data for classification. Conclusion: The quality of the clinical properties of the SAQ instrument for patients with Adolescent Idiopathic Scoliosis was low, due to the absence of clinical analysis properties or doubtful methodological quality. However, we recommend the instrument for the evaluation of the self-perception of the column in adolescents for its own organizational characteristics, its most current translation in the language if before the others by their sample and organization of statistical tests clearly described, compatible with the general proposal of the research and strengthening the exposures of the studied measurement properties.

Responsividade de parâmetros neuromusculares e capacidade funcional a dose mínima de treinamento resistido em mulheres de meia-idade e idosas
(Universidade Federal do Pará, 2023-04-24) NORONHA, Ádria Samara Negrão; COSWIG, Victor Silveira; http://lattes.cnpq.br/0097939661129545; https://orcid.org/0000-0001-5461-7119
Resistance training (RT) is an effective strategy to mitigate the loss of muscle strength and the risk of functional limitations that occur drastically after 55 years of age. However, there is evidence of inter-individual variations in responsiveness to resistance training, since some people can be responsive and others non-responsive to the same protocol. Thus, the objective of the present study was to verify the responsiveness of middle-aged and elderly women submitted to TR with a minimum dose approach and to verify the effect of the protocol on muscle strength and functional capacity of the participants. Twenty-two untrained women, mean age 64.3 ± 7.2 years, body mass 65.5 ± 9.2 kg, and height 152.3 ± 4.3 cm, randomly assigned to the Intervention Group (INT), submitted to the minimum dose protocol during 4 weeks, or to the Control Group (CON), who participated in two lectures and two stretching classes. The participants were evaluated for strength (1 repetition maximum in Leg Press 180º, Seated Rowing, and Straight Supine) and functional capacity (Timed Up and Go, Physical Performance Battery) before and at the end of the 4 weeks. For the statistical analysis it was performed the Analysis of Variance of repeated measures and Bonferroni post-hoc test for data with normal distribution, Mann Whitney U test for non-normally distributed data, Deltas of variation (Δ%) to present percentage of change and independent t test to compare the means of percentage of change between groups. The significance level adopted was p< 0.05. Levene's test was used to check the variance between groups. For classification of responsiveness, the standard deviation of the CON change score was multiplied by 1.96. Individuals outside this range were classified as High responders or Low responders. The results suggest 16.6% High responders in the 1RM of the straight supine and 8.4% in the estimated 1RM in the same exercise, with 25% High responders for average and peak velocity of the Sit and Stand test. Regarding the mean differences, we observed significant increases in muscle strength only for INT, with no differences between groups. Thus, it is concluded that 4 weeks of TR performed with a minimal dose approach presents a small rate of High responders for upper limb strength and lower limb speed. Furthermore, the training dose used seems to be insufficient to generate greater muscle strength and functional capacity adaptations than the control in middle-aged and elderly women.

Treinamento resistido de dose mínima aumenta força sem alterar a modulação autonômica cardíaca, função hemodinâmica e capacidade funcional de mulheres menopáusicas: um ensaio clínico randomizado
(Universidade Federal do Pará, 2023-04-28) DIAS, Rayra Khalinka Neves; COSWIG, Victor Silveira; http://lattes.cnpq.br/0097939661129545; https://orcid.org/0000-0001-5461-7119
Menopausal women have disorders in cardiac autonomic control that add to other deleterious effects such as functional and muscle decline. The aim of this study is to investigate the effects of minimal dose resistance training (RT) on cardiac autonomic modulation, hemodynamic parameters, strength and functional capacity in menopausal women. This study is a randomized clinical trial, submitted to the Brazilian Registry of Clinical Trials under the code RBR-2p4gpvk and approved by the Research Ethics Committee of the Institute of Health Sciences, Federal University of Pará (CEP–ICS/UFPA), under the opinion number 4,922,776/2021. The present investigation analyzed 29 women who were randomized to the training group (TG: 63,1±9,0 years) and control group (CG: 59,6±7,4 years). The TG performed the minimum dose RT twice a week for a period of four weeks. Assessments were performed before and after the protocol period, with anthropometric measurements, hemodynamic parameters (heart rate and blood pressure), autonomic modulation (RMSSD, SDNN, PNN50, HF, LF, LF/HF), functional capacity (6 min walk test and Short Physical Performance Battery), and strength with the test of 1 repetition maximum (1 RM). Two-way ANOVA (group*time) was performed with repeated measures with bonferroni post-hoc test and significance level p< 0.05. The results revealed that there was a group*moment interaction only in the autonomic index LnRMSSD (F= 1,01; ω 2= 0,055; p= 0,02), but the analysis of the main effects did not reveal differences between groups (d= 0.10; p= 0.70) and moments (d= 0.13; p=0.64). In addition, there was a significant interaction for the 1 RM bench press test (F= 10.30; ω2= 0.014; p< 0.01), but with no main group effect (d= 0.18; p= 0.62 ) and with moment main effect (d= 0.23; p< 0.01). In comparisons between moments, with significant improvements in the 1 RM seated row (F= 11,64; ω 2= 0,059; p< 0,01), 1RM bench press (F= 8,73; ω 2= 0,011; p< 0,01), 1 RM leg press (F= 19,77; ω 2= 0,095; p< 0,01). In this sense, minimal dose RT showed benefits in muscle strength, but it was not enough to produce autonomic, hemodynamic and functional adaptations in menopausal women.
