Muscle fatigue

[DanBor]

I have some questions about muscle fatigue.

1.What does it mean to have muscle fatigue like 4 days after very intensive workout?( I know it means that it was to much) but what exactly hapened in the muscles after that kind of workout-or to put it more clear: what kind of damage?

2. How much muscle fatigue is "normal" after intensive workout - for making progress? I know you don't suppose to feel fatigued after every workout.

Thanks.

but what exactly hapened in the muscles after that kind of workout-or to put it more clear: what kind of damage?

The soreness is caused by microscopic tears or stress of the connective tissues.I have read that these tears can cause scarring(although on a microscopic level) which could affect flexibility.Other sources i've read says this is untrue.
The soreness after a strenuous workout is usually caused by the negative(lowering under control) part of weight training.THis is due to the muscle contracting as it's lengthening.

How much muscle fatigue is "normal" after intensive workout - for making progress? I know you don't suppose to feel fatigued after every workout.

I would say if you've changed your program,performing exercises you aren't familiar with,changingthe rep/weight(drastically) then that would cause DOMS.
If you haven't done anything out of the ordinary or feel the soreness for quite a while(4 days seems quite long for someone who is used to training) then you may be over training.

Thanks for reply.
I actually did something that I usually don't do. My strenght-endurance training (lately) is based on some plyometric exercises (jumping lunges,..) and stances (front, horse). On sunday I 've mixed it up a little wight weights, I did side lunges (20-25 kg), to see reaction from my body. I still feel it today, but nothing serious I think, its almost completely gone.
