The regular practice of physical activities in the life of university students becomes secondary, either due to high academic demands or abrupt changes in lifestyle. However, as this academic environment is competitive and demanding, it can in turn change mood levels, anxiety and perception of these students; in this sense the exercise can be a great ally in facing the adversities of the academic period. Thus, the present study sought to evaluate and compare the levels of mood, anxiety and perception of body self-image of 66 university students. The results showed that the level of physical activity influenced the Total Mood Disorder (TMD), with the most active groups having an improvement over time [(SA group (6.55±29.03%, p=0.046) and MA (9.48±28.94%, p=0.023)]. However, the anxiety and self-image of the students was not verified improvement. Thus, it can be understood that higher levels of habitual physical activity can help university students in their mood patterns, thus helping with an improvement in the academic environment.

Our aim was to test the hypothesis that tele-supervised home-based exercise training (exercise) is an effective strategy for improving cardiovascular, respiratory, and functional capacity parameters in individuals that were hospitalized due to coronavirus disease 2019 (COVID-19). Thirty-two individuals (52 ± 10 years; 17F) randomly assigned to exercise ( N = 12) and control groups ( N = 20), had their anthropometric (weight, body mass index), hemodynamic (brachial and central blood pressure), vascular (arterial stiffness), ventilatory (pulmonary function and respiratory muscle strength), and functional parameters (handgrip strength, five-time sit to stand [FTSTS], timed up and go test [TUG] and six-minute walking test [6MWT]) assessed at baseline (30 to 45 days of hospital discharged) and after 12 weeks of follow-up. Both groups similarly increased ( P < 0.001) forced vital capacity (absolute and % of predicted), forced expiratory volume in the first second (absolute and % of predicted), and handgrip strength during follow-up. However, only exercise group reduced carotid-femoral pulse wave velocity (−2.0 ± 0.6 m/s, P = 0.048), and increased ( P < 0.05) resting oxygen saturation (1.9 ± 0.6 %), mean inspiratory pressure (24.7 ± 7.1 cmH ₂ O), mean expiratory pressure (20.3 ± 5.8 cmH ₂ O) and % of predicted mean expiratory pressure (14 ± 22 %) during follow-up. No significant changes were found in any other variable during follow-up. Present findings suggest that tele-supervised home-based exercise training can a potential adjunct therapeutic to rehabilitate individuals that were hospitalized due to COVID-19.

Background: Resting energy expenditure (REE) represents 60–75% of total daily energy expenditure and is mainly determined by fat-free mass (FFM). Indeed, the predictive equations vary according to FFM techniques and population characteristics. Therefore, this study aimed to explore the influence of dual-energy X-ray absorptiometry (DXA)-derived FFM on REE prediction by different predictive equations in a large and diverse cohort. Methods: A total of 1987 active and sedentary participants of both sexes (43.8 ± 19.4 years) underwent body composition assessment by DXA. REE was predicted using the Harris–Benedict, Schofield, Mifflin–St Jeor (weight- and height-based), and Mifflin (FFM-based) equations. Statistical analyses included Kruskal–Wallis, Spearman correlations, and linear regression. Results: Men presented higher absolute FFM, whereas women exhibited higher relative fat mass (FM) (p < 0.01). Across age groups, FFM declined progressively, while FM increased (p < 0.01). The REE differed significantly (p < 0.001) between equations, with the lowest values predicted from the FFM-based model, while the Harris–Benedict and Schofield equations showed the highest REE, especially in women. Strong correlations were observed between FFM and REE (r = 0.77–0.98; p < 0.01) for all age groups and equations, whereas FM showed strong correlations (r = 0.77–0.85; p < 0.01) only for the ≥60 years group. REE tended to be higher in active than sedentary participants, with the correlations to FFM and FM exhibiting a similar profile to that observed for the whole group. Conclusions: FFM showed a strong association with the estimate of REE in active and sedentary participants from both sexes and different age groups, but FM showed a similar trend in older participants only. Therefore, the increase or the maintenance of FFM with an active lifestyle is important to keep REE at high and efficient levels regardless of sex and age.

Introduction: Psychosocial functioning and body image are key dimensions of mental well-being and performance. Among professional dancers, competitive environments, aesthetic demands, and physical–emotional overload contribute to increased anxiety, stress, and mood disturbances, potentially impairing performance and heightening injury risk. Objective: To investigate longitudinal variations in psychosocial and emotional indicators among professional dancers throughout a season of rehearsals and performances. Methods: Thirteen dancers (9 women and 4 men) from a professional company were assessed across eight time points using the Brunel Mood Scale (BRUMS), State–Trait Anxiety Inventory (STAI-State), Recovery–Stress Questionnaire for Athletes (REST-Q 76 Sport), and Body Shape Questionnaire (BSQ). Data was analyzed using repeated-measures ANOVA with Bonferroni post hoc tests (p < 0.05). Results: Negative mood dimensions progressively increased (p < 0.01; η²p = 0.46, large), while vigor decreased (p = 0.03; η²p = 0.29, medium), indicating an inversion of the typical “iceberg” profile. Overall stress levels increased (p = 0.02; g = 0.53, power = 0.81) and perceived recovery declined (p = 0.04; g = 0.41, power = 0.78). State anxiety rose consistently (p < 0.01; η²p = 0.42), and body dissatisfaction, assessed via the BSQ, increased from “no concern” to “high concern” classifications (p = 0.03; g = 0.59, power = 0.84). Conclusions: Overall, the findings indicating a longitudinal pattern of increased psychometric strain indicators, inferred exclusively from psychometric trends, and conceptually consistent with a possible imbalance between perceived demands and perceived recovery, rather than reflecting objectively measured workload or recovery processes.
