Bloody stuff.

Here are the week long blood test results taken after running a 20 miler. The test was to analyze the normal recovery rate from a 20 mile run.

Blood Inflammation:
C Reactive Protein (CRP) - Used to measure muscle tissue damage.
Normal: 0–1.0 mg/dL or less than 10 mg/L (SI units)

Pre-20 mile run - .72
Post 20 mile run - .96
Day 1 - 3.49
Day 2 - 1.97
Day 3 - 1.33
Day 4 - 1.20
Day 5 - 1.16

Blood Enzymes:
Lactate Dehydrogenase (LDH) - Used to measure tissue damage. Also called lactic acid dehydrogenase. For adults, in most laboratories, the range can be up to approximately 200 units/L, but is usually found within 45-90 U/L.

Pre-20 mile run - 150
Post 20 mile run - 195
Day 1 - 156
Day 2 - 152
Day 3 - 152
Day 4 - 159
Day 5 - 155

Creatinine Kinase (CK) - is an enzyme found primarily in the heart and skeletal muscles, and to a lesser extent in the brain. Significant injury to any of these structures will lead to a measurable increase in CK levels. The primary damage in my case was to the skeletal muscle system.
Normal Range: Male-15-160U/L Female-15-130U/L

Pre-20 mile run - 96
Post 20 mile run - 176
Day 1 - 524
Day 2 - 263
Day 3 - 137
Day 4 - 135
Day 5 - 98

As you can see from the results it wasn't until after the 5th day that the levels went back down to the pre-20 mile run. After the 3rd day I felt no soreness in my legs yet the test results indicated I still had inflammation. The levels may have gone down sooner if I didn't swim, bike, or run during the 5 day test period. It looks like it takes 6 to 7 days before I would be fully recovered from the 20 mile run. I think this is good proof to me that the 3 weeks needed for tapering before a marathon is very important in order to perform well on race day.

I'm sure the results have more meaning but this is all I could gather for now. I'll have to wait for the professors and the graduate student to write their report on us and hope they give us a copy.

The next test will be on the effects of counterpulsation to improve recovery from a 20 mile run, will take place in early May.

That is so interesting. Especially that you had no sorness after 3 days, but the levels says you still had significant damage. How cool that you get to participate in that!! I can't wait to see how great you do in Boston!

Pretty cool stuff!

Wow! That is so interesting. I wonder how recovery runs factor in--does a short easy run help or prevent the reduction of inflammation? It seems to help, but like you said, it might feel like it helps but there could still be a lot of unsensed damage still there.

Hope you're enjoying your taper. This will be my first week with a real reduction in mileage and I'm looking forward to all the extra time. Less than 2 weeks!!

Thanks for the comment on my blog - you are right, sometimes I forget I am doing this for fun. :)

Thanks also for sharing the blood test results - one take away for me is to take the time to rest despite "feeling" better already.

Thanks for sharing. I'm a data freak so this is very interesting to me!

JeffM said...

Great data. I wonder if numbers in someone not in your kind of shape would take longer to come down? The May comparisons will be interesting.

Deb said...

Very cool info Louie. That training/science combo can take you far! I'll drop you a note next week.

Paul said...

Neat Stuff! I agree with the 3 week taper for a marathon. Can't wait to see the results!

first comes the Bunny weekend then Boston! :)

Hey Louie...lost your e-mail. shoot me another note and I'll get you my number (or if you have a day in mind now). We're in Boston Sat through Wed morning.
