Standard Grade PESkills & Techniques Mechanical principles: Transfer of weight Follow through Friction Force

Learning outcomes

Transfer of weight • This is when you shift your body weight from one part of your body to another • Transfer of weight is used in many skills to help add greater force into the action • In many actions weight is transferred from back to front as the hitting action takes place

Transfer of weight can….. • Increase the power / speed in the shot • Increase the distance the object travels • Help increase the accuracy of the shot • Helps maintain balance throughout the skill / technique • Give an example of a skill / technique that would require transfer of weight?

Follow through • This is the part of the action after the ball has been hit / thrown etc. • Your arm, racket, club, leg etc follows through in the direction that you want the ball to go.

Good follow through should give you… • Power • Distance • Accuracy • Speed to the object that you are hitting, pushing or throwing • Better balance when doing the skill

Force • The muscles create fore. The faster the muscle contraction, the greater the force • For every action, there is an equal and opposite reaction (Newton’s third law)

Force • When performing skills different forces are applied: • E.g. when a sprinter pushes back against the blocks this will propel him forwards – the harder he pushes, the faster he will go forwards. • In volleyball, a spiker pushes hard against the floor to propel them upwards as high as possible to make the spike easier.

Force • Force can also be in the same direction as the movement……. • E.g. a shot putter’s direction of force is forwards and upwards to try to create an optimum angle to propel the shot at maximum distance • A badminton player would apply force forwards and downwards in a smash

Friction • This is where two or more substances rub together • Friction can be an advantage in some activities and a disadvantage in other activities

Friction as an advantage • Footballers wear studs to increase the friction between them and the ground. This helps them to change direction and run faster. • Creating more friction between the arms and the water in swimming helps you to swim faster. Having a longer arm pull in the water helps push back more water, thus helping you to swim faster.

Friction as a disadvantage • In swimming friction between your body and the water slows you down. Therefore you need to get streamlined in the water to cut down friction. • In football during windy conditions friction between the ball and the wind will slow the ball down • In skiing, the skiers wear tight clothing to cut down the resistance between the air and their body to help them ski faster

Quiz time!!! • The following questions are based on knowledge from all of the skills and techniques theory so far…… • Write your answers on the sheet provided and your partner will mark them for you. • Good luck!!!

Question 4 • When describing a skill PAR stands for: • A)Preparation – Activity – recovery • B)Participation – Action – recovery • C)Preparation – action – recovery • D)Preparation – action - reactions

Question 5 • Whole – part – whole is a method of learning a skill, how could you use whole part whole to develop part of your front crawl action?

Question 6 • Give one benefit of being an automatic performer

Question 7 • Name a method of learning a skill which might be used for learning swimming technique. It involves trying an entire skill, then working on part of that skill, then trying the skill again.

Question 8 • A type of game which has additional rules to encourage good passing or use of a smash or use of a layup is called a __________ game.
