Hello students.
00:02
Today's first question is which includes the few mitochondria and large glycogen reserves than large diameter and densely packed myofibrils.
00:12
Slow fibers, intermediate fibers, fast fibers, red muscles and fatty muscles.
00:18
So the correct answer is fast fibers.
00:20
So the fast fiber is correct answer because we know that the skeletal muscles have two type of twitches.
00:28
They can be fast fiber or fast fiber which are known as type 2 fibers, type 2 muscles and slow fibers which are type 1 muscles.
00:42
So what happen is that the fast fibers are deprived of oxygen.
00:47
So if they do not need oxygen, obviously the mitochondria are going to be few.
00:53
Few mitochondria but they need they need large glycogen reserves so for energy storage they need glycogen so that is why fast fiber is correct answer now next is which muscle is adapted for occupation where you stand all day where you stand all day so suppose you are working somewhere and you have to stand all day so which muscle is adapted for that so for that we have slow fibers so for that we have slow fibers, slow fibers because we know that slow fibers need energy, energy for workout.
01:33
And they have more mitochondria.
01:36
They have more mitochondria.
01:39
So what happen is that? so what happen is that? these muscle fibers are more efficient.
01:45
More efficient for long period of time.
01:49
Long period of time.
01:50
It does not only help in the standing all day, standing all day.
01:57
Also, if you are working something, like if you are having active lifestyle and you are a runner or something, then these can also help because they are not easily fatigued.
02:07
Fatigue resistant.
02:09
They are fatigue resistant.
02:12
That is why they are more helpful.
02:14
Now, next question is, aging on muscular system does not have hypertrophy, small muscular fibers, decreased recovery from muscular injuries, exercise intolerance decreases, then muscle becomes less elastic.
02:29
We know that when we age, the muscles are becoming less elastic.
02:34
So this is not true.
02:36
Then exercise tolerance also goes on decreasing and decreased recovery whenever we get some injury, it takes more time to recover.
02:44
So these all are incorrect.
02:47
The answer correct one is first one, which is hypertrophy.
02:51
So hypertrophy means that hypertrophy of any organ, any cell, any part means that increasing in a number.
03:01
Increasing in a number...
