I was hoping to better understand why fatigue effects me in different ways depending on the type of program I’m on. For example, I recently completed a high volume block (high for me anyway) of training and by the end of it could noticeably tell I was short tempered, focus began to wane and I easily lost patience in general with things in my life. Just became a grumpy SOB.
I took a 2 week deload and am now currently on a low volume strength block. I’m about 5 weeks in and am beginning to feel the systemic/joint fatigue that can be expected when training heavier and more intensely. However, I still feel mentally “in the game” and not experiencing any loss of temper/patience whatsoever.
What might be the cause of this?
