Muscle fibers.
There are two types. Fast-twitch, and slow-twitch. I don't understand how they work but I understand the practical difference. Fast-twitch muscle fibers are able to move more weight, faster; but they fatigue quicker. Slow-twitch muscle fibers can't move as much weight or as fast, but they take longer to fatigue.
Running a marathon relies mostly on slow-twitch muscle fibers, while lifting maximum weight engages fast-twitch muscle fibers more than slow-twitch muscle fibers.
Lifting weights to failure engages fast-twitch muscle fibers, but only towards the failure. Until failure, slow-twitch muscle fibers are more involved.
And, lifting weights as quickly as possible rather than slowly and steadily engages fast-twitch muscle fibers quicker than does training to failure.
If anything here is incorrect, please correct me, as I'm basing my training upon these principles.
Thanks.![]()
Interesting, I haven't given a ton of thought to the fast twitch/slow twitch thing.
Heavy resistance (80% of max and up), low reps, has worked well for me.
I'm sure lighter weights and a ton of reps can work well for some people too.
