Burke
works
with a triathlete
who
finished
4
th in her
age
group
at
Wildflower
last
year.She
works in
Whistler, British
Columbia
and
has
three
children.Val
has
a
master
's
degree in exercise
physiology
and
has
been
using
lactate
testing
to
train
athletes
for nearly 10
years. < /font>
< p
class
= "bodyregular" > < font
size = "2" > All
testing
is
done
on
a
Computrainer,
using
the
cyclists
' own road or mountain bike. After a 15 minute warm-up
the
computrainer
is
calibrated
and
the
test
is
started.The
test
protocol
is
a
progressive
incremental
test, starting
at
100
Watts
and
progressing
by
either
25
or
40
Watts(depending
on
the
cyclists
' ability). Each stage
is
5
minutes, allowing
for steady state
to
be
obtained in both
the
blood
lactate
and
heart
rate
levels.At
the
end
of
each
stage
the
heart
rate,
blood
lactate
and
cyclists
' rating of perceived exertion is recorded.
The
cyclist
continues
with the test
until
they
fatigue.In
some
cases
cyclists
stop
at
anaerobic
threshold, depending
on
the
circumstances.

graphs
the
lactate
levels
and
heart
rates
versus
the
power
output, and
give
each
subject
an
indication
of
their
heart
rate
training
zones(see
below
)
as
well
an
indication
of
any
test - re - test
fitness
changes
that
have
occurred.Each
cyclist
receives
a
copy
of
their
test, plus
comments
and
training
recommendations.She
talks
to
them
about
the
sources
of
error
associated
with these zones,
and
then
they
try
the
training
zones
outside
on
their
bike
to
see
if they
appear
to
be
accurate. < /font>
< p
class
= "bodyregular" > < font
size = "2" > The
temperature in the
lab
versus
the
temperature
and
convection
riding
outdoors
may
influence
the
training
zones
slightly.If
the
person
is
fatigued
they
may
not
be
able
to
ride
hard
enough
to
get
into
their
higher
intensity
zones(threshold &
VO2
max
). Heart
rates
may
fluctuate
of
to
6
bpm
with daily fluctuations;
and
may
increase
or
decrease
over
time
based
on
fitness
changes
and
nervous
system
activation.Val
has
noticed
that
the
athletes
she
tests
2 - 3
weeks
after
their
final
week
usually
demonstrate
up
to
a
5 - 10 % increase in heart
rate
over
similar
power
outputs.This
may
be
due
to
changes in blood
plasma
volume
and
parasympathetic
drive
due
to
what
she
calls
the & quot;
Couch
Potato & quot;
effect
of
finishing
their
last
race
of
the
season
and
not
training
for a few
weeks
