ANSWER CHOICES:

A student athelete measured his running performance on a treadmill and found the following data 30 sec 10 min 5 MPH 20 min 3 MPH 0 sec 5 sec 10 MPH 15 sec 2 min 6 MPH 5 min 0 MPH 7 MPH MPH 6 MPH His trainer explained the findings to him in terms of muscle fiber activation and fatigue At 5 seconds, the fibers in his legs were running at full force, "spending down" their stockpile of By 15 seconds, these fibers were starting to burn fuel , which cut their "full throttle" speed slightly, but not all that much since they could use stored Around 30 seconds, however, this first batch of fibers was starting to fatigue due to By 2 minutes, however, his respiratory and cardiovascular systems were delivering enough for fuel 4 and his run slowed down a bit. to his leg muscles for his k fibers to take over and give him a speed boost. These fibers were burning fuel these muscles through conditioning, they had to wait for oxvgen from the blood to arrive before they could really get going + , which gives them more endurance, but since he had not built up much in Finally, around 20 minutes into this stress-test, his fibers were beginning to fatigue as well and he began to seriously lose speed

Explanation / Answer

1.FO.( fast oxidative fibres maintains force production even after large number of contractions.)

2.myoglobin( protein present in muscles which help in binding of oxygen)

3.anaerobically

4. glycogen( stores form of energy stored in muscles)

5.fuel depletion.

6. oxygen

7.FG.(fast glycolytic fibres ,unable to maintain more contraction without rest.)

8. areobically.

9.myoglobin.

10.creatin phosphate.
