1. A2 Physical Education
Long Term Technical Preparation
Technical Ergogenic Aids

2. Unit Learning Objectives:
To understand the mechanical aspects of
long-term preparation
To be able to discuss refinement of
technique, the perfect model, and use of
feedback for example through video and
computer software
To know about ergogenic aids, including
pedometry, heart rate monitoring and the
use of GPS technology

3. Lesson Objectives
 To develop an understanding of ergogenic aids,
including:
 Force Plates
 Pedometry
 Heart rate monitoring
 The use of GPS technology
 To be able to calculate the basal metabolic rate and
calorific expenditure

4. Force Plates
Watch the video and make relevant notes
on the use of Force Plate technology.
Apply it!
How would this benefit you in your sport?
Harley – This might interest you!

5. Pedometry
A device that calculates
the distance you have
walked or run
It senses your movement
and counts the amount of
steps you take
Why might this be useful?

6. Apply It!
You firstly need to work out your Basal
Metabolic Rate
E.G. Wrighty’s BMR is
BMR = 1 X Weight (KG) X 24 hrs
Wrighty’s BMR = 1 X 95 X 24
BMR = 2280

7. Now calculate my calorific expenditure:
I went for a 1KM swim this morning at 6am.
Level of Intensity
Type of Activity
Activity factor (x BMR)
Very Light
Seated /standing activities
Men = 1.3
Women = 1.3
Light
Walking 2.5 – 3mph
Men = 1.6
Women = 1.5
Moderate
Walking 3.5 – 4mph
Men = 1.7
Women = 1.6
Heavy
Jogging
Men = 2.1
Women 1.9
Exceptional
Athletic training
Men = 2.4
Women = 2.2
BMR x Activity Factor = Calorific Expenditure

8. Now apply it at home!
Using the information in the presentation
and the Pedometer, calculate your own
calorific intake.
Firstly you will need to work out your
average speed (distance x time)
So you will need to measure the following:
your stride length
How many steps you take (pedometer)
How long you are working for

9. NIKE + An advanced form of pedometry

10. Heart Rate Monitors
What do we know?
Accessible to most
athletes
Popular method of
measuring exercise
intensity
Sensors worn on the
chest sending data to
a wrist watch to
display working heart
rate

11. Remember how to work out your
maximum HR?
Remember how to use this to work out
training zones?

12. Heart rate monitors allow athletes to
predetermine what training zones they
should be working in
They can also give a good indication of
fitness levels and recovery
Heart Rate Task

13. GPS Technology
 Global positioning system
 A navigation system that
tracks your location and
can measure distance
travelled, average and
maximum speeds, stride
length and pulse rate
 What sports would this be
useful in?

14. Exam Question:
Identify examples of the types of technology used by
elite athletes in order to monitor their intensity. Select
one example, and highlight any advantages or
potential disadvantages for the athlete as a result of
this type of technology
