Lung capacity or total lung capacity (TLC) is the volume of air in the lungs upon the maximum effort of inspiration. Among healthy adults, the average lung capacity is about 6 liters. Age, gender, body composition, and ethnicity are factors affecting the different ranges of lung capacity among individuals. TLC rapid increases from birth to adolescence and plateaus at around 25 years old. Males tend to have a greater TLC than females, while individuals with tall stature tend to have greater TLC than those with short stature, and individuals with a high waist-to-hip ratio generally have a lower TLC.[1][2] Individuals of African descent have a lower TLC compared to individuals of European descent.[3] Additional factors that affect an individual's lung capacity include the level of physical activity, chest wall deformities, and respiratory diseases.
Doesn't help that the chinese have smaller lungs, I guess.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3495772/Slow deep breathing may also improve arterial oxygenation by increasing alveolar volume and gas exchange at the alveolar capillary membrane level. The latter particularly increases when interstitial lung fluids are increased. Indeed, it has been reported that paced slow deep breathing improves blood oxygenation in subjects chronically exposed to HA
Then there's adaptogen type herbs and this one in particular: https://www.ncbi.nlm.nih.gov/pubmed/22164439/ Known as "maral root"Abstract
The administration of the extract from Rhaponticum carthamoides (150 mg/kg, p.o., for 10 days) in combination with dosed low-power exercise in rats with experimental myocardial infarction led to an improvement of hemorheological indices, which was manifested by a decrease in the whole blood viscosity, aggregation of erythrocytes, and increase in erythrocyte deformability. In particular, the extract from R. carthamoides contributed to an increase in the hematocrit/blood viscosity, which was indicative of an improvement of the blood overall oxygen transport capacity. In addition, administration of the extract in combination with dosed exercise favored normalization of the lactate and pyruvate concentrations in blood of rats with myocardial infarction.
