Standard Grade Physical Education Speed

2.
What is SPEED? <ul><li>It is the ability to cover a distance or perform a movement in as short a time as possible. </li></ul>

3.
Some examples: <ul><li>A sprinter would use their whole body to generate speed </li></ul><ul><li>A soft ball player would use their arms (part of their body) to swing the bat as quickly as possible </li></ul><ul><li>* Different activities require different types of speed. </li></ul>

4.
Reaction Time <ul><li>This is the length of time it takes to respond to a stimulus. For example:- </li></ul><ul><li>A sprinter responds to the sound of a gun. </li></ul><ul><li>A tennis player responds to the action of their opponent. </li></ul><ul><li>The quicker the reaction time the greater the advantage. </li></ul><ul><li>Reaction time can be improved through practising the activity itself, eg. A series of sprint starts. </li></ul>

5.
Running speed depends on a number of factors... <ul><li>Range of movement in ankles, hips and shoulders </li></ul><ul><li>Strength of muscles </li></ul><ul><li>Stride length and frequency </li></ul><ul><li>Correct technique </li></ul><ul><li>Force exerted by leading leg </li></ul><ul><li>Ability of muscles to cope with a build-up of lactic acid </li></ul>

6.
How can speed be improved? <ul><li>Using strength training methods to strengthen the leg muscles which will enable them to contract faster. </li></ul><ul><li>A combination of aerobic and anaerobic exercises. This increases muscular endurance and allows muscles to increase their ability to cope with lactic acid build-up. </li></ul>

7.
Tasks: <ul><li>1. Describe two situations where speed would be beneficial in an activity of your choice. </li></ul><ul><li>(E.g, Forward beating a defender in hockey) </li></ul><ul><li>2. Q50 P21 (Questions in SGPE) </li></ul>
