I'm sure we've all read articles about
how they use blood work to help them solve lots of mysteries in the
research world. For instance they are finding that the horses pulled
from Tevis for metabolic reasons are typically low in Chloride. So I
decided to set aside some hat money to have blood work done and see
what I could learn.
I talked with another endurance rider
who has blood work done on his endurance horses from time to time. He
said he thought it was worth wile and pointed me in the direction of
Dr. Mike Foss.
So when I vetted Bunny in on Friday I
talked to Dr. Foss. He told me he I would get the clearest picture of
what was going on if I brought for a blood draw right after I
finished, the sooner the better. So I did, I crossed the finish line
and took her over to get her blood drawn.
Dr. Foss called me on Tuesday with the
results. He said her electrolyte levels were all great. I'd done a
good job with that. He told me he was sure I already knew this but
just in case... he wanted to make sure that I understood that I'd
have to change my electrolyte plan if the conditions of the ride were
different. I assured him I understood that. Unfortunately there is no
one size fits all plan for anything in endurance. In some ways I kind
of like that, the problem solver in me gets a lot of work in this
sport.
Next Dr. Foss told me that Bunny's
blood work did show that she had been ridden pretty hard. There was
starting to be evidence of some muscle cell breakdown and her
bilirubin was slightly elevated. We talked about her 12 miles of fit
throwing and about how strategies to keep her calmer at the start
were going to be very important for her. Lastly, she was a starting
to get a little bit dehydrated by the end of the ride (her skin
tinting was an A but blood work is my accurate). Dr. Foss did make
sure to clarify that she was fine, she didn't tie up, there wasn't
anything wrong with her just to know that she was ridden hard.
I have to admit I had a lot of mixed
feeling when I got off the phone. First off I was glad that I was on
with her electrolytes. The first summer I did endurance with her I
didn't electrolyte her enough and at the end of one ride she had an
electrolyte imbalance that resulted in a rolling heartbeat for a few
hours. A great vet at the ride talked me through it and we decided it
was an electrolyte imbalance and with his encouragement I rode her
again the next day (it was a two day ride) and electrolyted her a lot
more and she did great.
The part about her being ridden hard
didn't surprise me either. Thanks to the heart rate monitor I knew
that her 12 miles of fit throwing was all most all anaerobic (she was
working beyond the point that her body could adequately supply oxygen
to her muscles) and that takes it toll. I also could feel at the end
of the ride that she was a little tired and I haven't felt that
before. So I guess it's good to know that my intuition about my horse
was right, she was tired.
But I have to admit that there was part
of me that wanted the blood work to come back basically declaring us
endurance excellence. Like in in Marry Poppins when the children want
to measure her to see how she measures up and the tape measure says
“Mary Poppins, practically perfect in every way”. But the reality
is that we aren't perfect and most sane people don't expect us to be.
The good news is we are learning and
having fun. We continue to learn and hopefully we'll get a little
better each time.
Besides, being perfect might get boring
