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 COVID-19 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 COVID-19 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 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 post-COVID-19 group presented significantly higher sympathetic activity than active subjects in control group. Parasympathetic activity was significantly increased in physically active subjects in 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.

Weekly Physical Activity

Background: Sedentary behaviour and physical inactivity along with body mass are identified as critical determinants of vascular health along with body mass in young adults. However, the relationship between potential physical health and anthropometric variables with high blood Eid pressure remain unexplored in young adults from the United Arab Emirates region. Methodology: We administered a cross-sectional study in young adults assessing their self-reported physical activity levels, anthropometric variables (body mass index and waist circumference) and ambulatory blood pressure. The associations among potential physical health, anthropometric variables and high blood pressure were analysed through logistic regression after necessary transformation. Results: Of 354 participants (176 males, 178 females), we found 17.79% (n = 63) had higher mean arterial pressure. Males (n = 40; 22.73%) had higher risk of hypertension than females (n = 12.92%). Weekly physical activity levels (β = −0.001; p = 0.002), age (β = −0.168; p = 0.005) and gender (β = −0.709; p = 0.028) were found to be more strongly associated with hypertension risk than the body mass index (β = 0.093; p = 0.075), waist circumference (β = 0.013; p = 0.588) and the weekly sitting time (β = 0.000; p = 0.319) of the individuals. Conclusions: Lower physical activity was associated with hypertension risk compared to other modifiable risk factors such as waist circumference, body mass index and sedentary time in college-going young adults. Public health measures should continue to emphasise optimisation of weekly physical activity levels to mitigate vascular health risks at educational institution levels.

Insufficient Physical Activity

Swedish physical activity on prescription (PAP) is an evidence-based method to promote physical activity. However, few studies have investigated the effect of Swedish PAP on physical fitness, in which better cardiorespiratory fitness is associated with lower risks of all-cause mortality and diagnose-specific mortality. Direct measures of cardiorespiratory fitness, usually expressed as maximal oxygen uptake, are difficult to obtain. Hence, exercise capacity can be assessed from a submaximal cycle ergometer test, taking the linear relationship between heart rate, work rate, and oxygen uptake into account. The aim of this study was to evaluate exercise capacity in the long term, following PAP treatment with enhanced physiotherapist support in a nonresponding patient cohort. In total, 98 patients (48 women) with insufficient physical activity levels, with at least one component of the metabolic syndrome and nonresponding to a previous six-month PAP treatment, were randomized to PAP treatment with enhanced support from a physiotherapist and additional exercise capacity tests during a two-year period. A significant increase in exercise capacity was observed for the whole cohort at two-year follow-up (7.6 W, p ≤ 0.001), with a medium effect size (r = 0.34). Females (7.3 W, p = 0.025), males (8.0 W, p = 0.018) and patients ≥58 years old (7.7 W, p = 0.002) improved significantly, whereas a nonsignificant increase was observed for patients <58 years old (7.6 W, p = 0.085). Patients with insufficient physical activity levels who did not respond to a previous six-month PAP treatment can improve their exercise capacity following PAP treatment with enhanced support from a physiotherapist during a two-year period. Future studies should include larger cohorts with a control group to ensure valid estimations of exercise capacity and PAP.

<b><i>Introduction:</i></b> Our aim was to evaluate the changes in choroidal thickness (CT) and volume (CV) following aerobic physical exercise in healthy young adults. <b><i>Methods:</i></b> This study included 72 eyes from healthy volunteers between 22 and 37 years old. Using the International Physical Activity Questionnaire, total physical activity was computed. Measurements using an autorefractometer, ocular biometry, and spectral-domain optical coherence tomography using the Enhanced Depth Imaging protocol were taken. OCT was performed as a baseline measurement and after performing 10 min of dynamic physical exercise (3 and 10 min post-exercise). The choroidal layer was manually segmented, and the CT and CV in different areas from the Early Treatment Diabetic Retinopathy Study grid were obtained. <b><i>Results:</i></b> In healthy adults, at 3 min post-exercise, CT was higher in the subfoveal, the 3-mm nasal, and the 6-mm superior areas. Between 3 and 10 min post-exercise, the CT was reduced in all areas, and in some areas, the values were even smaller than the baseline measurements. The CV values showed changes after exercise similar to those of thickness. The total CV recovery after exercise was related to sex and physical activity level. <b><i>Conclusion:</i></b> Individuals with higher physical activity habits had greater CV at rest than those with lower physical activity levels. During exercise, healthy young people adjust CT and CV. At 3 min post-exercise, CT and CV increase. Women and individuals with greater physical activity levels reduce their total CV more than others during recovery.

El objetivo del presente estudio fue comparar el efecto de una unidad didáctica intermitente de acondicionamiento físico en Educación Física sobre los niveles de actividad física y capacidad cardiorrespiratoria entre estudiantes con un perfil saludable/no saludable de capacidad cardiorrespiratoria. Ochenta estudiantes de 2º-3º curso de Educación Secundaria fueron asignados aleatoriamente al grupo control y grupo experimental. El grupo experimental, dividido en perfiles saludable/no saludable, realizó una unidad didáctica intermitente de acondicionamiento físico para mejorar la capacidad cardiorrespiratoria. El grupo control trabajó un contenido diferente durante el mismo tiempo y con la misma frecuencia, pero sin hacer hincapié en la mejora de la capacidad cardiorrespiratoria. Antes y después de la intervención, la capacidad cardiorrespiratoria se evaluó objetivamente mediante el test de ida y vuelta de 20 metros. Los niveles de actividad física fueron medidos objetivamente a través de un pulsómetro durante las clases de Educación Física. Ambos perfiles tuvieron mayores niveles de actividad física durante las clases de Educación Física que el grupo control (p < .001). Sin embargo, solo los estudiantes con un perfil no saludable mejoraron significativamente sus niveles de capacidad cardiorrespiratoria tras la unidad didáctica (p < .01). Aunque una unidad didáctica intermitente de acondicionamiento físico parece tener un efecto similar en los niveles de actividad física de todos los perfiles de capacidad cardiorrespiratoria de los estudiantes, solo mejora la capacidad cardiorrespiratoria de los estudiantes con un perfil no saludable. Abstract. The purpose of the present study was to compare the effect of a Physical Education-based physical fitness intermittent teaching unit on physical activity levels and cardiorespiratory fitness among students with healthy/unhealthy cardiorespiratory fitness profile. Eighty students from 2º-3º grades of Secondary Education were randomly assigned to the control group and experimental group. The experimental group, divided into healthy/unhealthy profiles, performed a physical fitness intermittent teaching unit to improve the cardiorespiratory fitness. The control group worked a different content during the same time and with the same frequency, but without emphasizing cardiorespiratory fitness improvement. Before and after the teaching unit, students’ cardiorespiratory fitness was objectively measured by the 20-meter shuttle run test. Participants’ physical activity levels were measured objectively using a heart rate monitor during Physical Education lessons. Students from both profiles had higher physical activity levels during Physical Education lessons than the control group (p < .001). However, only students with an unhealthy cardiorespiratory fitness profile statistically improved their cardiorespiratory fitness levels after the teaching unit (p < .01). Although an intermittent physical fitness teaching unit seems to have similar effect on physical activity levels of students from all cardiorespiratory fitness profiles, it only improves the cardiorespiratory fitness of those with an unhealthy one.
