The chimney swift's genus name, Chaetura, is a combination of two Greek words: chaite, which means bristle or spine, and oura which means tail. This is an apt description of the bird's tail, as the shafts of all ten tail feathers (rectrices) end in sharp, protruding points.
Definition of Anaerobic Capacity. Anaerobic capacity is your body's capacity to run its systems without using oxygen. It contrasts with aerobic capacity, which requires oxygen as fuel. It is therefore important for high-intensity, low-duration activities such as lifting weights or sprinting. Sprint tests are an effective way to measure your anaerobic threshold.
ABSTRACT | REFERENCES. The vital capacity was defined by Hutchinson1 as the quantity of air a person is capable of expiring after the deepest possible inspiration. Although many thoracic diseases are known to diminish the vital capacity, in few, if any, is the reduction more striking than in pneumonia.The sudden fall of the vital capacity in pneumonia and the subsequent increase incident to uncomplicated convalescence are sufficiently uniform to be of diagnostic significance.BSTRACT | REFERENCES.
