Evidence suggests aerobic exercise and L-arginine supplementation may accelerate COVID-19 recovery. Hence, this study aimed to examine the effects of an acute aerobic exercise session with L-arginine supplementation on selected psychomotor and physiological parameters in cyclists recovered from COVID-19.</p> <p><strong>Methods:</strong> Thirty-two male mountain bikers aged 18-25 years from Qazvin, Iran were randomized into four groups of eight: aerobic exercise + L-arginine supplementation, control, aerobic exercise + placebo, and L-arginine alone. Participants underwent pre- and post-testing surrounding an acute aerobic cycling session. The Shapiro-Wilk test assessed normality of data distribution. Analysis of covariance evaluated between-group differences. Statistical analyses were performed using SPSS version 26.</p> <p><strong>Results:</strong> Analysis of covariance revealed significant between-group differences on psychomotor performance, maximal oxygen consumption, and peak anaerobic power variables (all p&lt;0.05). Post-hoc Bonferroni tests showed the aerobic exercise + L-arginine group had significantly greater improvements than aerobic + placebo and L-arginine groups (p&lt;0.05), with no differences between L-arginine and control. </p> <p><strong>Conclusion:</strong> Aerobic exercise combined with L-arginine supplementation appears an effective strategy for enhancing psychomotor and physiological performance in cyclists recovered from COVID-19.</p> https://journals.kmanpub.com/index.php/jarac/article/download/698/2788
