caffeine

[ZGzaZ]

i was wondering, what effects does caffeine have on your system taken directly before lifting?

There are numerous studies that state that caffeine increases skeletal muscles contractions.

There is no doubt it increases your heart rate and body temperature to some degree both from the effects of the caffeine and the hot beverage itself.

I have always had my best workouts after having a nice cup of coffee. After a cup of coffee peak caffeine concentrations are usually acheived within 30 minutes.

However, I only drink 1 cup of coffee in the morning and have decaf before a workout. I found that I struggled sleeping if I took caffeine in the evening (that's when I workout) and then the following day I'm so tired that I need more caffeine to workout and so on and so on. Not good when you need sound sleep to grow.

After cutting down to just one cup of coffee in the morning I sleep so much better! Also, even if you think your sleeping well internally you may not be due to the effects of the caffeine.

It can be a great stimulant, but it supresses the uptake of glucose into the cells up to 30-40%. This is bad for that post workout refeed. It also decreases insulin sensitivity for a longer period. With the wrong foods, it can create the environment of Type II Diabetes.

If you make a pot of coffee in the morning and have a cup or so,but leave the remainder in the pot...when I get home form work I reheat the leftover coffee..always been curious to know if the caffeine content of coffee degrades over time after brewing

Caffeine will help with fatigue, and it delays the sensation of fatigue. It has no effect on the strength of a rested muscle. Increased endurance in exercise lasting 10-60 minutes. It increases FFA mobilization. Increases catecholamines. May increase potassium reuptake by muscles during repeated contractions, causing quicker recovery.

As far as increase in HR and BP, caffeine has little effect during exercise...during rest it will raise both, however.

Its effects tend to increase when performance decreases. In other words, as you fatigue caffeine has more of an effect. At higher altitudes, when your VO2max will be lower, caffeine can help your endurance.

High GI foods.

Can you simplify that for me. from time to time and the amount of information inside my head I tend to forget the easiest of things.

What is GI?

lololololol

Glycemic index...high GI foods are pastas, rice, etc...anything that gives high insulin spikes.

Oh, and I forgot to mention...caffeine has better effects on people that don't use caffeine regularly, so I wouldn't use it all the time.

spatts, you just ruined my morning

 

[spatts]

I was sitting here drinking my coffee when I typed it.

 

[Zander1983]

I was drinking mine as I read it

 

[spatts]

Did we just bond?

[MsBeverlyHills]

its got a great effect..why do youthink lifters take ECA stacks???

 

[spatts]

Because it has great effects....but not because it's without negative effects.

How many llifters do you see taking ibuprofen for muscle aches even though we've repeatedly warned that it halts muscle protein synthesis?

Risk is relative, I suppose.

 

[spatts]

Moderation...ain't that the truth.

 

[MsBeverlyHills]

yeah & theres negative effects to training when your too tired-- like smashing your head on the bar (done that btw)

theres risks for sure...but in moderation I think your a-okay

 

[Zander1983]

taking ibuprofen ... halts muscle protein synthesis

You learn something new each day...
