As you age, are you more likely to see atrophy of slow or fast twitch muscle fiber?

Just an interesting way to open up conversation. I already know the answer, but may be enlightening for some...........

Answer:

As you age and allow your muscles to atrophy, fast twitch muscle fiber can shrink down until it literally disappears. Slow twitch muscle fiber is less likely to atrophy at the same rate as you need this type for walking around, getting on and off the couch, picking up that fork to feed yourself. Eventually, you will change the ratio between slow and fast twitch muscle fiber. Strangely enough, after this happens, and resistance training is undertaken, it is the slow twitch muscle fiber that responds quickest and gains the most bulk, opposite of what happens when you are young.

It's white fonted. To see it, all you have to do is highlight the area and you will be able to read it.
