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

6                   73.70         73.15          72.65

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.

6           21                  3 yr filly, 17 days

6          -10                  3 yr. colt, 18 days

 

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     257 651  2.53)

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.

Summary

 

Overall, allowance horses benefitted the most from the

use of Lasix on their second race with the stuff. 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

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.
