Figure 2 Scatter plots of the δWR and δVO2 at the VAT point. The scatter plot shows a positive linear correlation between δWR@VAT and δVO2@VAT (r=0.495, P=0.003). VAT – ventilatory anaerobic threshold; δWR – work rate difference between 2 exercise tests with and without a mask; δVO2 – oxygen consumption difference between 2 exercise tests with and without a mask.
