Recovery rates
The recovery rate is the time it
takes for the heart to return to its
resting state after exercise.
This can indicate the performer’s
level of fitness; the quicker the
recovery, the fitter the performer.

Recovery phases of exercise
sessions need to be planned just
like the rest of the session.
Damage and injury can result if
recovery phases are not planned
and incorporated into a training
programme.

These times of lower-level activity
and rest allow the body to repair
and evaluate the outcomes of the
session.

Rest and recovery gives time for
restoration of:
• Energy-producing enzymes in
muscle fibres
• Stores of carbohydrates in muscle
cells
• Hormonal balance and immune
system

• Recovery allows the muscles to
become stronger as muscle
proteins, energy stores and
enzymes that help to improve the
lactic acid threshold increase.

Target zones and
training thresholds
A target zone is the range within
which a performer needs to work for
aerobic training to take place.

A training threshold is the point
that must be exceeded before an
effect or result can be produced.

For example, a runner could go for a
jog around a running track to train for
a marathon, but they would not reach
the point or threshold they must
exceed in order to improve their
stamina.
However, completing a 10 mile run
would probably reach and pass their
training threshold, helping to improve
their stamina and performance in
preparation for the marathon.

The intensity of exercise affects the
heart rate, which in turn can affect
how the type of exercise helps the
body.
For example, aerobic respiration is
obtained by training between 60 to
80 per cent of the maximum heart
rate target zone.

Athletes training continuously, just
below the anaerobic threshold, will
build up their lactic acid tolerance,
allowing the body to continue
exercising while coping with greater
levels of lactate without muscular
pain or fatigue.

Task
This is a physical task in order to
find out who has the best recovery
rate in the class.
Equipment needed:
• A set of stairs
• A stopwatch
• Paper and pen to record results

Method:
1. Take your resting heart rate over
30 seconds.
2. Quickly and safely go up and
down the stairs for a minute to
raise your heart rate.

3. For 10 minutes, measure and
record your heart rate for 30
seconds at the beginning of every
minute.
4. The person who returns to their
resting heart rate first has the
best recovery rate.
