The study had the goal to study the relationship between resilience, stress and injuries in the sport context. Eight female athletes, part of the Rhythmic Gymnastics Brazilian Team along the Olympic Cycle 2015–2016 participated in the study, with a mean age of 20.4±2.5 years. The following instruments were used: RESTQ-76 Sport, CD-RISC 10, documental analysis of physical therapy records, and structured questionnaire. Data was analyzed by descriptive statistics (frequency, mean and standard deviation); Repeated Measured ANOVA with Bonferroni’s post-hoc, Student’s “t” test, Friedman test, Pearson Correlation Coefficient, Cohen’s d, and inductive thematic analysis. We found relatively stable levels of stress and recovery across the season; total recovery levels were higher than stress at all four measured timepoints (p<0.05); All athletes had at least one injury, with a total of 14 injuries; No significant correlations were found between the quantitative scores of resilience, stress and recovery; Training and the sport’s scoring system were the most relevant perceived stressors; athletes presented meta-cognition and a non-positive evaluation (neutral) of stressors; Social support was considered the main psychological factor for the resilience process; such process resulted in improved control and interpretation of emotions; Our hypothesized model proposes that, in the relationship between stress and injuries, resilience acts by optimizing the injury recovery process. It was concluded that resilience plays a role in the process of injury rehabilitation and stress control in elite rhythmic gymnastics’ athletes.

Objective. The aim of this study was to analyze the reproducibility of a protocol using the maximal isometric strength test of the trunk in elderly women aged above 60 years, without low back pain. Methods. Twenty-one physically inactive elderly women, who had not engaged in any activity or exercise program in the past three months, participated in the cross-sectional study that consisted of two days of evaluations for the maximal isometric strength of the extensor and flexor muscles of the trunk, with a 48 h interval between the sessions. A platform with fixed seating was used, which allowed the fixation of the hip and lower limbs, with a load cell connected to a linear encoder. To verify the reliability of the test, the interclass correlation coefficient, variation coefficient, minimum detectable difference (MDD), standard error of measurement, and Bland–Altman graphs were calculated. Results. No statistical difference was observed between the first and second evaluation, which indicates that there was no learning effect. Interclass correlation coefficient values were classified as very high and high for extensor (0.98) and flexor (0.86) muscles, respectively, besides low variation (9% for both muscle groups) and acceptable values for minimum detectable difference (extensors = 51.1 N, flexors = 48.9 N). In addition, the Bland–Altman analysis revealed low bias and values within the limits of agreement. Conclusion. It is concluded that the test of maximum isometric strength of the trunk in healthy and trained elderly people presents high reliability. These values proved to be reliable if performed in at least two evaluation sessions, which confirms the hypothesis of the authors by the consistency of the measurement test.

Introdução: A doença de Charcot-Marie-Tooth (CMT) é a condição neurológica geneticamente determinada mais prevalente no mundo, os indivíduos apresentam fraqueza muscular, atrofia e déficit sensorial. Objetivo: Avaliar a força muscular de membros inferiores e tronco em indivíduos com CMT tipo 2 e suas correlações com equilíbrio e funcionalidade. Métodos : Estudo transversal, com amostra de quinze indivíduos no grupo CMT2 e quinze no grupo controle. Para avaliar FM, utilizou-se o dinamômetro; equilíbrio utilizou-se a estabilometria e a Escala de Equilíbrio de Berg (EEB) e para desempenho funcional, através do Time Up and Go (TUG). Resultados e Discussão: Houve redução significativa da FM proximal de MMII, abdominais e paravertebrais, menor pontuação na EEB e menor TUG do GCMT2 em relação ao GC. Ao analisar as correlações da força de MMII e tronco com a VCoPAP no GCMT2 (indivíduos com escore leve), os músculos com maior correlação foram os extensores/abdutores/adutores de quadril e paravertebrais, enquanto que nos indivíduos moderados/graves, houve correlação regular com flexores de quadril e paravertebrais. Nas correlações com a EEB (escore leve), os músculos paravertebrais obtiveram correlação regular e nos mais acometidos houve correlação forte com os extensores/flexores/abdutores de quadril e regular com os abdominais. Na análise das correlações com o TUG (escore leve), observou-se correlação regular com os flexores do quadril, abdominais e paravertebrais. Nos indivíduos moderado/graves os flexores do quadril e paravertebrais tiveram correlação leve. Conclusão : Os indivíduos com CMT apresentam perda de FM proximal e essa redução leva a alterações no equilíbrio e funcionalidade.
