Introduction: The COVID-19 pandemic has led to social isolation measures in different contexts. In endurance sports, competitions worldwide have been canceled, affecting behavioral, psychological, and physical aspects. Objective: This study aimed to assess potential associations between stress, motivation, behavioral changes, and physical fitness in endurance athletes, and time in social isolation. Methods: A cross-sectional study with the participation of 201 athletes, including mountain bikers (n = 89), runners (n = 88) and triathletes (n = 24). Each participant answered questions about time spent in isolation; body weight; changes in training schedule during the isolation period; levels of motivation; stress levels; loss of physical fitness; what aspect of physical fitness was most jeopardized during the isolation period; alcohol consumption; quality of sleep; quality of diet; and whether they had been ill during the isolation period. Results: The results showed significant differences between the percentage of runners (4.5%) and triathletes (16.7%) who had been isolated from 1-10 days, and between the percentage of cyclists (41.6%) and runners (68.2%) in 11-20 days and >20 days (28.1% and 9.1%) respectively. Social isolation was significantly associated with at least one variable for the three groups of athletes; however, the runners were the most affected by the pandemic, presenting an association with low motivation, high stress, poorer quality of sleep, increased alcohol consumption, and loss of physical fitness. Conclusion: Our study showed that the period of social isolation, specifically over time > 10 days, generated significant changes in the perceptions of motivation, stress, alcohol consumption, and physical fitness of endurance athletes, with runners being the most affected group. Level of Evidence III; Diagnostic studies - Investigation of a diagnostic test; Study of non-consecutive patients, without a “gold standard” applied uniformly.
OBJECTIVE: This study aimed to analyze changes in the daily routine and life perceptions of older adults due to the coronavirus disease 2019 pandemic. METHODS: This is a cross-sectional study conducted with 338 older adults (93 men and 238 women) residing in southern Brazil. An online questionnaire consisting of 20 questions was created using the Google Forms platform and was distributed to older adults (> 60 years of age) during the isolation period caused by the coronavirus disease pandemic. Data analysis was conducted through Student's-t and χ2 tests. RESULTS: Our results showed a significant association between social isolation and sex (p < 0.01), revealing that women experienced higher levels of social isolation than men. We observed that 82.21% of the older adults participating in this study reported changes in their social routines during the pandemic. CONCLUSIONS: During this period of extended social isolation, women reported more negative effects than men.
Aim: to compare the impact of different resistance exercise orders on postexercise hemodynamic measures in resistance-trained nonhypertensive middle-aged and older women. Methods: Twenty-three women (age 50-78 yrs) were randomized into two resistance training (RT) groups: one group started training sessions performing multi-joint exercises followed by single-joint exercises (MS, n = 12; 58.92 ± 5.53 yrs), while the other group performed their sessions in the opposite order (SM, n = 11; 57.93 ± 11.89 yrs). Both groups performed their RT sessions composed of 7 exercises performed in 3 sets of 10-15 repetitions maximum. Blood pressure was measured by automated equipment during pre-training and at 10, 20, 30, 40, 50, and 60 min after the training session. Results: Repeated-measures analysis of variance (ANOVA) identified an isolated effect of time only for systolic blood pressure (p = 0.003) with statistically significant reductions in pre-session measurement at 60 min post-session in both groups (MS: 117.67 ± 15.89 mmHg vs. 111.25 ± 11.84 mmHg and SM: 118.64 ± 15.13 mmHg vs. 111.50 ± 15.62 mmHg). Regarding diastolic blood pressure and subjective perception of effort, no difference was identified between groups (p > 0.05). Conclusion: We conclude that a RT session can promote post-exercise hypotension for systolic blood pressure after 60 min of recovery in middle-aged and nonhypertensive older women regardless of the exercise order.
Este estudo teve como objetivo analisar a prevalência do fenótipo Cintura Hipertrigliceridêmica e suas associações com os níveis de atividade física, estado nutricional e perfil lipídico de escolares da rede pública de ensino. Os 448 escolares com idade entre 10 e 18 anos foram analisados pela massa corporal, estatura, índice de massa corporal (IMC), circunferência de cintura, triglicerídeos, colesterol total, HDL-C, LDL-C, colesterol não HDL, glicemia em jejum e tempo de atividade física semanal. Os resultados evidenciaram uma alta prevalência do fenótipo CHT nos escolares (n = 125; 27,9%). O grupo diagnosticado com fenótipo apresentou maior massa corporal, IMC, colesterol total, LDL-C e colesterol não HDL e menor nível de HDL-C em relação ao grupo sem o diagnóstico do fenótipo. Porém, para medidas de glicemia em jejum e tempo de atividade física os grupos não se diferiram. A análise de associação por meio de regressão logística, mostrou que o fenótipo CHT associou-se com o sexo, estado nutricional e colesterol total, onde os meninos apresentaram 2,0 (IC95%: 1,3 - 3,2); obesos 6,2 (IC95%: 2,7 - 17,2) e níveis de colesterol acima 150 mg/dL 3,5 (IC95%: 2,1 - 5,7) vezes mais chances de terem o fenótipo. Logo, essa pesquisa evidenciou uma alta prevalência de CHT em escolares da rede pública, sendo os meninos, obesos e escolares com níveis de colesterol total inadequado os sujeitos com maiores chances de terem o fenótipo. Todavia, destaca-se a importância do acompanhamento dessas variáveis ao longo do ano em todos os escolares, considerando o período de fortes mudanças pelas quais podem alterar rapidamente os elementos analisados.
