Fig. 3From: Influence of exercise duration on respiratory function and systemic immunity among healthy, endurance-trained participants exercising in sub-zero conditionsX5 response to exercise in cold, between atopic and non-atopic participants. Open circles represent atopic individuals and closed circles non-atopic participants. Panel A: Change in X5 from baseline; data are mean and standard deviation. Grey points and lines represent the 30-min trial and black points the 90-min trial. Panel B: Mean difference in X5 between 30- and 90-min trials with 95% CI. *, significant difference between 30-and 90-min trials, p < 0.05Back to article page
