do ppl use caffeine before practice workouts or before competition races? I was wondering about this becase if absuing to much caffeine for its nervous system stimulation could cause some sort of fatigue for the next session.
How much are we talking? Is it daily?
I drink, on average, probably 3-5 cups of green or white tea a day (some days closer to 7-8 and some all decaff, depends), in the mornings with breakfast and before my workout (which starts late morning/early afternoon normally). I don’t use energy drinks or caffeine pills outside of meets. I’ve never had issues with using caffeine and having fatigue unless I was using more than usual for a meet and even then, it’s hard to say the fatigue was solely from the caffeine.
If I were looking to use caffeine for its stimulation benefits, I would personally reserve it to before competitions. I like to feel I have something I can step up to come competition, and this would fall into that category. Also, I believe using it sparingly, as you would i only before competitions you get a good effect from its supplementation, but if you stat using it regularly, before each session, then the body adapts and doesn’t get the reaction it once did from it.
I also heard something about motivated sprints (boosted with either mental state\substances) in practice causing increased recovery time…
so is it better to stay relax when doing speed work ?
yes it is.
i regularly drink 2 x cups of coffee per day - 1 morn and 1 lunch. Mostly train late afternoon well after the effects have worn off.
i hate the feeling of caffeine just before training, its terrible. Heart rate rises too high, recovery sucks and the nerves feel like crap.
That’s interesting. I have had red bull before the last couple of sessions, for no other reason than I have been offered them really. I haven’t noticed a dramatic change in how I feel, but yesterday my cleans were awful. Last Friday I did 92.5kg for 6, and then I did 95kg for 6 off 7 attempts, but yesterday I did 2 sets on 85kg off 8 attempts each. There were other factors I’m sure. Earlier in the week my sister trapped my index finger in a car door, so it’s still quite painful and possibly affected my grip. Also I think I have been eating less in an effort to get a calorie deficit, which may have had an effect. The rest of my lifts seemed alright though, so I have a feeling the finger may be the biggest contributing factor.
I do think that the amount I eat noticeably affects my lifting on a day to day basis. If I go to training feeling hungry I may lift worse than normal. Does anyone else experience this? Is it logical or just something stupid in my head?

Same here, I def agree with that!

I know that Darren allowed his weight to fluctuate throughout the year, a different approach to the one Charlie recommends, but come March time he would diet hard, but he would eat a good breakfast on weight days so he would feel stronger going into the gym. I guess there may be something to be said for that.

Just googled ‘suppressing appetite’ and found some interesting tips…
Totally agree. And most of the time it’s based on no empirical evidence.
Ignorance and arrogance are a terrible combination…
