I have had a few muscle pulls/strains in the past 4-5 months or so and the only thing I can think of that I have been doing differently is adding in more stimulants than in the past. I pulled my quad and the day I did it I took a sample of a preworkout that I had got for free, it was loaded in caffeine and there were very noticeable stimulant effects (I drink lotsof coffee and my coffee drinking has nothing on this stuff).
Just last week I pulled/strained my lat (which is one of the most painful things I have ever experienced). The weird thing is I wasn't even doing back work, I strained it while locking out a back squat. I wasn't even using much weight since I am coming back from the above mentioned quad pull but I guess I was stressing hard at the top and I must have been flexing my lat hard and it was already too tight and boom, strained. I was trying to cut some weight so I was taking an EC stack, not a ton, just once a day of 200mg C, 25mg E.
I know stimulants have a diuretic effect to them but would it also lead to an increased chance of a muscle pull or strain? My hypothesis is that the stimulant use raises the tension on your muscles, as in I will be bouncing my leg more, clenching my muscles more, etc. and that effect reduces flexibility and leads to injuries if you are already tight (which I definitely am).
Any thoughts? I could be completely off here and am well aware of that, I just want to reduce my chances of injury when I get this lat healed up (I have already added in much more mobility work than I had been doing).
