The mean values of all parameters were assessed for a normal distribution using the KolmogorovSmirnov test. Objective assessment of increase in breathing resistance of N95 respirators on human subjects. The resting lactate values were lower with SMs than with Co (Co 0.920.26mmoll1 vs. SM 0.790.25mmoll1). Top number (systolic) in mm Hg. Here are 6 common myths about face masks - and why individuals with heart disease need to take note: 1. Effect of breathing oxygen-enriched air on exercise performance in patients with chronic obstructive pulmonary disease: randomized, placebo-controlled cross-over trial. The participants then performed a double incremental cycle ergometer test (DIET; the first and the second exercise period interrupted due to a 5min recovery period) until exhaustion to assess the maximal power output (Pmax) and the MLSS due to the lactate minimum in the second load period19,20.
