Protein Drinks - Page 3

OK all, how about jumping in at the deep end... Isn't quite a bit of the point of these protein drinks to get protein to muscles quickly in the hour after exercise allowing them to repair torn muscle fibres? A lot easier than timing your meals for just after exercise.? Just my two SA cents worth (still worth bugger all but improving!!!!)

[quote author=ricstern link=board=18;threadid=920;start=15#23122 date=1038401554]I'm not arguing that we don't need protein, just that requirements are very small (although recent research suggests endurance riders require more than sedenatry, age and gender matched controls), this is around ~ 1.2 - 1.5 g per kg body mass per day for your average club cyclist, which for an average 72 kg rider would be 86 - 108 g protein per day. On the other hand CHO requirements run at about 5 - 8 g CHO/kg body mass per day, i.e., 360 - 576 g CHO.<br /><br />Ric<br /><br />[/quote]<br /><br />I agree with your figures Ric, hence the reason I support protein supplementation. I'd have to consume in the region of 3-4 chicken breasts per day to reach my required protein intake, which is no problem in terms of quantity, but the downside being the consumption of &amp;quot;undesireables&amp;quot; i.e. fat. 3-4 chicken breasts would also supply me with almost 60g of fat, which I don't want. I don't want to sound like I eat by numbers, quite the contrary, but I do find it easier to eat &amp;quot;normally&amp;quot; and just make up the deficit by supplementing. It's also easier to control.

VO2 thanks. however, i'm not sure how you can't eat 'normally' and not reach those protein figures? I'm an ovo-lacto vegetarian, and on my last nutritional analysis i was eating around ~ 150 - 200g protein per day without supplementation, ~ 18 - 24% of total energy intake. that was on a low-fat diet (&amp;lt;20%).<br /><br />Ric

Ric, you must of been consuming a fair amount of dairy products tho? 150-200g is a massive amount of protein per day.

typically, i just have milk in cappucino (one a day), occasionally have cereal and milk, and maybe ~20g of cheese a day. so not very much from dairy sources.<br /><br />i'd estimate (without digging out my analysis) that typically, half of the protein would come from sources such as bread and pasta.<br /><br />i don't think i've ever analysed anyones diet, where they're been below the recommended amount of protein. i've seen plenty of people eat nowhere near enough carbohydrates, but never protein.<br /><br />Ric

Interesting. Another topic of discussion is the BV (biological value) of the protein content of food. Not many years ago, eggs were considered to have a BV of 100%. Nowadays, whey protein supplements have BV's of 160%, which means a high amount of BCAA's (Branched Chain Aminos).<br /><br />Interesting discussion nonetheless. Thanks Ric.

It looks like I found this thread after it was pretty much abandoned. It does seem to be pertinent for many of the newer threads I've seen posted so maybe it will still answer some questions for people with questions about dietary protein needs.

I'm with ricstern and 2Lap on this particular topic. Most people are already consuming more protein than they need so supplimentation isn't likely to be necessary and may even prove detrimental if they're an endurance athlete and trying to get too many of their calories from protein. Since protein doesn't convert well to energy, they may do better by decreasing protein intake and increasing carbohydrates.

I noticed you mentioned a "MacDOUGALL", Vo2. I'm curious; would this be Dr. John McDougall? If it is, I've seen some of his information on protein requirements and, to the best of my recollection, he seems to recommend levels pretty substantially below the recommendations I've noted in your posts.
