The purpose of this study; to examine the effects of aerobic and strength training on physical activity level, quality of life and anxiety-stress disorder in young adults with and without COVID-19. In this context, the study was planned by including 15 participants between the ages of 18-25 who had COVID-19 and 15 who did not have COVID-19. Data were collected by applying the Personal Data Form, IPAQ (International Physical Activity Form), SF-36 Quality of Life Scale, Coronavirus Anxiety Scale (CCS), Respiratory Function Tests (PFT), Six Minute Walk Test (6MWT). Aerobic training and strengthening training were applied to people with and without COVID-19 for 12 weeks. Aerobic exercise (walking) was given for 40 minutes 5 days a week, with the target heart rate being 70% of the age-corrected maximum heart rate. Strengthening exercises were applied to the upper (triceps, biceps, deltoid, pectorals) and lower (quadriceps, hamstring, gastrocnemius, tibialis anterior, hip adductors, hip flexors, hip extensors) extremities and back muscles (trapezius, latissimus dorsi) with theraband (resistance band). Significance test of the difference between two means in comparing independent group differences when parametric test assumptions are met for statistical analysis in line with the data collected from the participants; When parametric test assumptions are not met, Mann Whitney U test is used to compare independent group differences, while when parametric test assumptions are met to examine dependent group differences, the significance test of the difference between the two spouses is used; When parametric test assumptions were not met, the Wilcoxon paired two sample test was used. In all analyses, p < .05 was considered statistically significant.
