Lasix: What really
happens?
I just finished reading the following article about
furosemide
(lasix) and the impact on the performance of a horse.
"Furosemide reduces accumulated oxygen deficit in
horses
during brief intense exertion", K.W. Hinchcliff, et al.
Journal of Applied Physiology, Vol 81., No.4 pp. 1550-1554,
Oct 1996
A total of nine standard bred fillies 3-4 years of age and
383-453 kg
body weight were used during the trials. Three different test conditions were
performed after being treated with furosemide. What they found was that
furosemide increased O2 comsumption and reduced accumulated
oxygen deficit.
The oxygen deficit reduction was due to an increase in the
mass-specific
rate of O2 consumption.
The high intense work was 2 min. at 120 percent
of Vo2max on a treadmill with a 4 degree incline.
The test were conducted 4 hours after being treated with
lasix. Each horse
was denied food or water during the 4 hours. All feces were
collected and weighed at 3.75 hours. The weight lost was added during
one trial. The
average weight loss for the nine horses over the 3.75 hrs.
was around 3-4 percent of body weight (25-35 pounds). Races horses at the
track are not denied water so the weight loss will be lower.
Lasix treated horses showed higher oxygen comsumption, lower
oxygen deficit,
higher hematocrit, and lower plasma lactate in
recovery. Lactate values
during the test were about the same.
Basically the improvement in the horses performance was do
to the weight loss
and a lower oxygen deficit.
So if weight loss is one of the factor that impacts on
perfomance. What is
the potential improvement in perfomance that can be
expected?
I ran one of my Energy Programs to get the impact of large
weight losses.
Distance,furlong
Time, 0lbs. Time, 10lbs. Time,20lbs

8
98.90 98.25 97.55
10 124.70 123.85
123.05
The improvement works out to be about 13-15 Beyer speed
points at the distances
for a 20 pound weight loss (about 2 percent) for a 1000
pound horse.
I decided to see how much improvement is actually obtained. I survey the DRF
from 11 July 1997 to find horses that race at the same
distance and track without
lasix and then with lasix.
The horses had to return within 30 days or less
when returning with lasix added. A number of horse when getting lasix first
time are switching distances or surface conditions.

As you can see a number of horses improved their Beyer
numbers while a couple
regressed. I did not
check the second time lasix with the horse that regressed.
In my own handicapping I mark all horses that are first,
second or third time lasix.
Sometimes the the initial dose is to low. By the third time the dose should be
correct.

A few weeks ago I posted a review of a article on lasix and
horses. In that
posting I showed that the improvement in
performance from lasix was more related to loss of
weight. My
posting showed the impact of weight carried and the
improvement
in Beyer speed points. I also included a sample from the
DRF.
Bill Gillock responded to my posting about the sample I
showed
and offered so comments.
During the last few week Bill has run
his database to show the impacts of lasix on
performance. Bill
separated his database by number of starts and class: maiden
special, maiden claiming, claiming, and allowance. Bill shows
1st, 2nd, and 3rd or more times on lasix and as a control
group
horses not getting lasix.
The non-lasix horses show improvement
in perfomance up to start 10. After 10 starts all classes show
a reduction in performance in the next start. This improvement
follows a similar trend that Quirin showed on Page 90
"Winning at
the Races" for layoff horses returning to race. Horses that race
at the same distance show a maximum improvement in speed
ratings
between race 6-11 and then dropoff. Horses that change distance
dropoff after 4-5 starts.
Could the dropoff in Bill's data
actually reflect horses that become injuried or sour on
racing?
Or is this an indication of overtraining? More on overtraining
at the end.
Overall every class improved with 1st and 2nd time lasix
(about
2-3 BSF). Allowance
horses did better on 2nd time lasix.
Bill
did not have 3rd time lasix separately. The biggest impact is
first time lasix when compared to the last start. The race the
horse most likely bled in.
As a group horses with three or more
starts on lasix are less talented then non-lasix horses.
As a handicapping angle for 1st and 2nd time lasix horses
check
back to in their past performance about 3 to 5 races and add
about 3 Beyer points to their speed rating as projection for
the
current race.
Observation: Lasix really does not enhance the performance
of a
races horse. What is
does do is help the horse continue to race
and to run at the proper distance (routers). The 2-3 Beyer speed
point increase is within the noise.
As an addenum to Bill's data I would like to report on a
article
about overtraining and the impact on performance.
Article:"Changes in maximum oxygen uptake during
prolonged
training, overtraining, and detraining in horses" by
Catherine M.
Tyler, et al, Journal of Applied Physiology, Vol 81, No. 5
pp
2244-2249, Nov 1996
(you can find this article on the web at: www.jap.org)
Thirteen standarbred horse were rested for four months
before
training. The
training program included four phases:
phase
one-endurance (7wk), phase two-high-intensity (9wk), phase
3-overload training (18wk), and phase 4 detraining (12wk).
During phase 3 the horse were divided into two groups, one
control group and one overload group. Horse improved their max
oxygen uptake Vo2 max by 29 percent during training. At week 11
in phase three training was increased because horse were not
showing signs of overtraining. Overtraining started to appear in
the overload group at week 31 about four weeks after the
increase
in work. Run time to
fatigue during standardize treadmill
test were used as the measure to determine the impact of
overtraining. Vo2max
did not change in the overload group,
however run time to fatigue dropped by around 15
percent. Other
factor that showed up in the overtrained group was a drop in
weight about 30 pounds, CO2 production and respiratory
exchange
were lower. Both
factors are related to lactate accumulation and
glycogen depletion.
Both the control group and the overload
group were tested to fatigue once each week during phase 3.
We could assume that this is like a race a week. The control
group did not show the impact of overtraining in 18 weeks
(phase
3). Some standarbred
can race 30 to 40 plus times during one
year. The overload
group showed that a horse could go off form
within 4 weeks if overworked. Over the 12 wks of detraining
the horse lost about 15 percent of Vo2max.
Relative to Bill's study we see a horses go off form in 10
races
on the avg. which could from 18-25 weeks. The control group of
standardbred did not go off form in 18 weeks while the
overtrained group went off form in four weeks (15th week
phase 3)
when the workload was increased.
Knowing that lasix causes weight loss and overtraining
(going off
form) causes weight loss.
Wouldn't it be nice to have the
weights of all the horses to determine current condition?

Larry,
I wrote a program to compare Speed Figures before and after
Lasix.
I could only compare TrackMaster speed figures and only
compare with
the "AvgDstSurf" or Average Speed at Distance and
Surface. I don't
think they use only the exact distance, but anything close.
I don't
have data readily available to go back more than 2 PPs so I
had to
use the AvgDstSurf number to compare with. I wish I could
have
used the best at distance number as I suggested but it is
hard to
extract it given my data base format right now.
Cl = Class
L = Lasix (1=First
Time Lasix, 2=2nd)
n-inAvg = Number of horses in AvgDstSurf to compare change
in Speed
(ex. 3-5
means (>=3 and < 5))
Sts=Number of horse in AvgSpeed
Tot=Total Speed change AvgSpeed
AvgSpeed=Tot/Sts
So for example: MSWs with 2nd time lasix increase their
speed figure
by 2.53 points when compared with their own AvgDstSurf taken
from 1
race prior. (MS 2 1-2

I am running the same number for horses with 3rd time lasix
or more
and with no lasix to get a comparison. I'll let you know.
Please let me know if you don't understand how I arrived at
these numbers. I should have a clearer head later in the
day.

No 3rd time lasix data yet, but here is what I do have. It
is similar
to what I sent before but I have added a couple of columns.
Most of the lasix and non-lasix numbers show an increase in
speed.
I think this is because I only use PP data to generate the
stats.
Using PP data biases the numbers to horses which continue
racing.
For example, these numbers do not contain horses which raced
FTL and never raced again. I need the PP data to get the
speed
figure for the race. That is why I compare the with the NOL
and LAS horses.
Class = Class of race (only Maiden Claiming, MSW, Claiming
and
Allowance
used).
nStat = Number of races used to determine Average speed for
a horse
to use as a
reference for change in speed (effect of lasix).
nFTL = Number of horses
with First Time Lasix with nStat and Class.
FTL = Average
increase in speed with FTL when compared with
average speed
for the horse running same distance and
surface in
previous races.
2TL = Average
increase in speed for Second Time Lasix.
LAS = Average
increase in speed for lasix 3rd time or more.
NOL = Average
increase in speed with no lasix.
FTL-N = FTL - NOL
2TL-N = 2TL - NOL
Note: number of horses with 2TL, LAS and NOL is more than
the nFTL
number. The number of NOL horses is much less
than LAS
horses.

Overall, allowance horses benefitted the most from the

1.64 for 2TL-NOL for all AL horses is the most solid.
First Time Lasix showed the most increase for Claiming
horses (1.47 FTL-N for all CL).
I was going to post this to the list but never got around to
it.

Subject: Lasix Study: Male/Female and Age Breakdown
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
I broke the numbers down further by age and sex. 2yo or not
a 2yo is
the best I could do with my database. Also, I could only
guess
the sex condition of a race by looking for
"Fillie" in the description.
For example: I don't have "gelding" designations
for the horses.
I haven't really looked at the data, but it did reduce the
sample
size quite a bit. I compiled all of the "all"
lines at the end to
provide a larger sample size for comparison.
Cla = Class of race
(only Maiden Claiming, MSW, Claiming and
Allowance
used).
Age/Sex = 2yo or not a 2yo. Male or Female.
nStat = Number of races used to determine Average speed for
a horse
to use as a
reference for change in speed (effect of lasix).
"all" means all runners no matter what the nStat.
nFTL = Number of
horses with First Time Lasix with nStat and Class.
FTL = Average
increase in speed with FTL when compared with
average speed
for the horse running same distance and
surface in
previous races.
2TL = Average
increase in speed for Second Time Lasix. The average
speed for
each horse (used for comparison) includes the FTL
race if that
race was run at today's distance and surface.
LAS = Average
increase in speed for lasix 3rd time or more.
NOL = Average
increase in speed with no lasix.
FTL-N = FTL - NOL
2TL-N = 2TL - NOL
Note: number of horses with 2TL, LAS and NOL is more than
the nFTL
number. The number of NOL horses is much less
than LAS
horses.
