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.
Limited Improvement. The average personâs lung capacity can be improved only 5 percent to 15 percent even with frequent intense aerobic workouts, according to Noakes. Everyone is born with a specific maximum lung capacity, called VO2 Max, which refers to the rate of oxygen flow.When your heart rate increases during aerobic exercise, your oxygen consumption increases: this provides the necessary energy to your muscles for the strenuous activity.imited Improvement.
