I think A dont count me on that
Answer:
Fast glycolytic fibers use anaerobic metabolism to produce energy which is used by the muscle for high tension contraction but these muscles fatigue quickly.
- It has amount amount of glycogen and have very quick acting myosin ATPase.
Slow oxidative are known as resistant fibers which generates energy(ATP) by the help of aerobic system.
- It depends on the delivery of oxygen and have red fibers which is smallest of all the fibers.
- It is found in marathon runners and its main function is to maintain posture.
Answer:
The correct answer is - Changing PRF.
Explanation:
Pulsed wave Doppler uses the principle of Doppler effect that objects that move changes the characteristic of sound waves. It is creates images by sending the short and quick pulses of the sound, it helps in the determining the velocity of blood in a exact time and location.
PRF or pulse repetition frequencies, is a Doppler sampling frequency that can affect the acoustic exposure of the scanning. PRF is measured in KHz.
Thus, the correct answer is - changing PRF.
