Long Term Technical Preparation

Technical Ergogenic Aids

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

Lesson Objectives

To develop an understanding of ergogenic aids, including:Force PlatesPedometryHeart rate monitoringThe use of GPS technology

To be able to calculate the basal metabolic rate and calorific expenditure

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!

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?

Apply It!

You firstly need to work out your Basal Metabolic Rate

E.G. Wrighty’s BMR isBMR = 1 X Weight (KG) X 24 hrsWrighty’s BMR = 1 X 95 X 24

BMR = 2280

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 = 1.3Women = 1.3

Light Walking 2.5 – 3mph Men = 1.6Women = 1.5

Moderate Walking 3.5 – 4mph Men = 1.7Women = 1.6

Heavy Jogging Men = 2.1Women 1.9

Exceptional Athletic training Men = 2.4Women = 2.2

BMR x Activity Factor = Calorific Expenditure

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 lengthHow many steps you take (pedometer)How long you are working for

NIKE + An advanced form of pedometry

Heart Rate Monitors

What do we know?Accessible to most

athletesPopular method of

measuring exercise intensity

Sensors worn on the chest sending data to a wrist watch to display working heart rate

Remember how to work out your maximum HR?

Remember how to use this to work out training zones?

Heart Rate Task

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

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?

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
