Autonomic function recovery and physical activity levels in post-COVID-19 young adults after immunization: an observational follow-up case-control study

Coronavirus disease 2019 (COVID-19) has detrimental multi-system consequences. Symptoms may appear during the acute phase of infection, but the literature on long-term recovery of young adults after mild to moderate infection is lacking. Heart rate variability (HRV) allows for the observation of autonomic nervous system (ANS) modulation post-SARS-CoV-2 infection. Since physical activity (PA) can help improve ANS modulation, investigating factors that can influence HRV outcomes after COVID-19 is essential to advancements in care and intervention strategies. Clinicians may use this research to aid in the development of non-medication interventions. At baseline, 18 control (CT) and 20 post-COVID-19 (PCOV) participants were observed where general anamnesis was performed, followed by HRV and PA assessment. Thus, 10 CT and 7 PCOV subjects returned for follow-up (FU) evaluation 6 weeks after complete immunization (two doses) and assessments were repeated. Over the follow-up period, a decrease in sympathetic (SNS) activity (mean heart rate: p = 0.0024, CI = −24.67–−3.26; SNS index: p = 0.0068, CI = −2.50–−0.32) and increase in parasympathetic (PNS) activity (mean RR:p = 0.0097, CI = 33.72–225.51; PNS index: p = 0.0091, CI = −0.20–1.47) were observed. At follow-up, HRV was not different between groups (p > 0.05). Additionally, no differences were observed in PA between moments and groups. This study provides evidence of ANS recovery after SARS-CoV-2 insult in young adults over a follow-up period, independent of changes in PA.info:eu-repo/semantics/publishedVersio

Role of body mass and physical activity in autonomic function modulation on Post-COVID-19 condition: an observational subanalysis of Fit-COVID study

The harmful effects of coronavirus disease 2019 (COVID-19) can reach the autonomic nervous system (ANS) and endothelial function. Therefore, the detrimental multiorgan effects of COVID-19 could be induced by deregulations in ANS that may persist after the acute SARS-CoV-2 infection. Additionally, investigating the differences in ANS response in overweight/obese, and physically inactive participants who had COVID-19 compared to those who did not have the disease is necessary. The aim of the study was to analyze the autonomic function of young adults after mild-to-moderate infection with SARS-CoV-2 and to assess whether body mass index (BMI) and levels of physical activity modulates autonomic function in participants with and without COVID-19. Patients previously infected with SARS-CoV-2 and healthy controls were recruited for this cross-sectional observational study. A general anamnesis was taken, and BMI and physical activity levels were assessed. The ANS was evaluated through heart rate variability. A total of 57 subjects were evaluated. Sympathetic nervous system activity in the post-COVID-19 group was increased (stress index; p = 0.0273). They also presented lower values of parasympathetic activity (p < 0.05). Overweight/obese subjects in the post-COVID-19 group presented significantly lower parasympathetic activity and reduced global variability compared to non-obese in control group (p < 0.05). Physically inactive subjects in the post-COVID-19 group presented significantly higher sympathetic activity than active subjects in the control group. Parasympathetic activity was significantly increased in physically active subjects in the control group compared to the physically inactive post-COVID-19 group (p < 0.05). COVID-19 promotes changes in the ANS of young adults, and these changes are modulated by overweight/obesity and physical activity levels.info:eu-repo/semantics/publishedVersio

EFEITOS DE UM PROGRAMA DE EXERCÍCIOS AQUÁTICOS EM CRIANÇAS COM DIABETES DO TIPO 1: RELATO DE CASO

O objetivo foi relacionar o comportamento do nível glicêmico de crianças com diabetes mellitus tipo 1 com um programa de exercícios aquáticos. Duas crianças com idade cronológica de 8 e 12 anos e diagnóstico clínico de diabetes mellitus tipo 1 foram submetidas a um protocolo de exercícios aquáticos. O protocolo foi executado duas vezes por semana. As crianças foram avaliadas inicialmente e reavaliadas após as 18 sessões de treinamento quanto aos dados antropométricos e sinais vitais. A glicemia periférica foi verificada no início e fim de cada sessão. Após a execução do protocolo, observou-se redução dos níveis diários de glicemia das crianças, bem como a diminuição da necessidade de correção glicêmica por meio da insulina de ação rápida. As evidências apresentadas apoiam o uso de exercícios aquáticos como uma modalidade terapêutica a ser incorporada no processo de tratamento de crianças DM1, como uma prática não medicamentosa para o controle glicêmico

Capsaicin Analogue Supplementation Does Not Improve 10 km Running Time-Trial Performance in Male Amateur Athletes: A Randomized, Crossover, Double-Blind and Placebo-Controlled Study

Background: To investigate the acute effects of a capsaicin analogue supplement on 10 km time-trial performance and physiological responses in amateur athletes. Methods: Twenty-one participants (age = 29.3 &plusmn; 5.5 years, weight 74.2 &plusmn; 11.3 kg, height 176.0 &plusmn; 0.0 cm, fat mass 12.7 &plusmn; 3.8%, V˙O2max 62.7 &plusmn; 8.4 mL&middot;k&minus;1&middot;min&minus;1), completed two randomized, double-blind trials: capsaicin analogue condition (Capsiate (CAP) = 24 mg) or a placebo (PLA) condition. The participants consumed two doses of 12 mg of CAP or PLA capsule 45 min before and immediately at the start of each trial. The time required to complete 10 km, lactate concentration, maximum heart rate (HRpeak), and rating of perceived exertion (RPE) were recorded. Results: The 10 km time-trial performance (CAP = 45.07 &plusmn; 6.41 min vs. PLA = 45.13 &plusmn; 6.73, p = 0.828) was not statistically significantly different between conditions. No statistically significant differences between conditions were detected for lactate concentration (p = 0.507), HRpeak (p = 0.897) and RPE (p = 0.517). Conclusion: Two doses of a 12 mg Capsaicin analogue supplement did not improve performance and physiological responses in a 10 km running time-trial in amateur athletes
