I have been using the products
EFS and
Ultragen from 1st Endurance.
Ultragen has been great, but the first few times I used
EFS, it gave me what I would call "rot gut". The last few times have been great so maybe my stomach has adapted. Anyway, in my interest of their products, I subscribed to their newsletter which I found to be very informative and reinforced many of the things I have learned from Hammer's website.
In 1st Endurance's latest newsletter, they discuss the importance of Amino Acids. Also called Branched Chain Amino Acids, or
BCAA's, these are very important to the body during and after exercise. Of particular importance is
Glutamine.
Glutamine is especially important because it fuels our immune system and can be significantly depleted during prolonged intense exercise. Most of the time, the three Spin Doctor
Cyclewerks group rides each week could all be classified as prolonged intense exercise. Keeping adequate
glutamine levels in the body is especially important to preventing Over Training Syndrome (
OTS) and upper respiratory trace infections (
URTI / sinus infections).
Over the past 2 years, I have experienced both
OTS and
URTI's, but especially the
URTI's. It didn't seem to matter when I started my training, but just about 3 months after starting serious training, I would get a sinus infection. I think part of this was due to inadequate
glutamine supplementation. I also have had
OTS at times which were more related to the addition of stress outside of cycling, but I believe
glutamine supplementation would have been beneficial in order to prevent my issues with
OTS.
So, what should you do? The recommendations from the article are:
1. Supplement with 5 – 10 grams of glutamine during a pre-exercise meal approximately 1-2 hours before a long exhaustive training session (e.g. greater than 3 hours).2. Supplement with 0.5 - 1.0 gram/hour during training (included in a carbohydrate, electrolyte drink).3. Supplement with approximately 5 grams of glutamine immediately post-exercise (included in a recovery drink).Seems like a lot of
glutamine, right? Well, I like to keep things simple. Supplementing with
glutamine immediately post-exercise using a recovery drink is going to give you your best opportunity to supplement with
glutamine. This supplementation will help prevent the greatest threat to your training and improvement: getting sick or
OTS. Another point the article makes is to supplement with a full complement of
BCAA's in order to keep a balance of
BCAA's in the body. Both
Recoverite from Hammer and
Ultragen from 1st Endurance are good products for immediate post-exercise recovery as they provide adequate amounts of
glutamine while many other recovery products provide
glutamine in lower amounts.
The article also spends time discussing the benefits of
BCAA supplementation during exercise to increase performance. While I agree with their conclusions, I think this is not nearly as important as supplementing during recovery and the article admits that the research is not as clear in this area.
