Application of forces - Typical question Jan 08 Qu 3 Maximising effort during performance is largely concerned with the correct application of forces. What forces act on a player when they are running during a game? (3 marks) June 2010 Using ‘Newton’s First and Second Laws of Motion, explain how a swimmer dives off the starting blocks. (4 marks)
Forces Forces cause ; A force is a movement push or a pull “A force is that which alters or to alter a body’s or of in a line.” If a body changes or , a has been applied tends state of rest uniform motion straight velocity direction force
Forces affecting motion • Muscular/action forces • Reaction forces • Gravity • Air resistance • Friction
Air resistance Gravity Friction Equal and opposite Ground Reaction Force Action force of muscular contraction Forces acting on a sprinter
Newton’s Laws • 1st Law: • A body will remain in its / • until affected by a • A body has a to change its state of motion force rest reluctance state of motion
Applying Newton’s 1st Law • Sprinter remains in on • blocks until a causes him to • change his • Ball keeps moving until a • causes it to change its set position force state of motion force state of motion
2nd Law - Momentum • All objects in motion have mass and • Product = • Momentum = velocity (m x v) momentum quantity of motion
Newton’s 2nd Law • The rate of change of is • to the force causing • the change, and the change takes place in the in which the force was • applied • In sport, remains constant and • therefore momentum equates to momentum directly proportional direction mass acceleration
Applying Newton’s 2nd Law • The (size) and of • force applied by the sprinter to the blocks • determines the and • of received – because mass remains constant • Acceleration is to • applied magnitude direction magnitude acceleration direction proportional force
Newton’s 3rd Law • To every force there is an and • reaction force equal opposite
Applying Newton’s 3rd Law • The sprinter applies a to the ground. • This results in a force that causes movement • The sprinter cannot move the • Reaction force from ground = muscular force reaction earth/blocks Ground Reaction Force
Commercialisation - Typical question Many elite sports are now commercialised and seen as a form of entertainment. Discuss the suggestion that an increase in the ‘commercialisation’ of sport has been beneficial for performers and the sport. (7 marks)
Commercialisation Spectators media sponsorship merchandising professionals 30 years Idea of sporting events being used to make money Sport gains income from: / / / Income used to pay players – Commercialism increases in last
Commercialisation • Sport seen as a • Where the becomes the driving force in sport • The sale of - the major source of sports funding • Broadcasting rights for Premier League now worth commodity market TV rights £1.1 billion a year
Media and sport • Sport – – to report/show • More readers/viewers – more , more , more • Need to make information provided interesting – cheap sales income advertising inform or sensationalise
Role of sport to media • to suit demands of media • Share of entertainment market – • Increased interest – • from TV rights • and income Adapted peak time viewing more participants Income Marketing advertising
Television and advertising • TV cameras – • Pre-game /during game advertising • Advertising • Sponsors name /logo • Sponsor: logos on pitch hoardings in media competition venue stand
Sport Has Changed For TV • One day and 20:20 • Penalty • Timings – starts/kick-off to suit TV • Use of in tennis/cricket • 3rd umpire in /TMO in • Camera cricket shoot outs more viewers hawkeye cricket rugby angles/position/playercam
TV changes sport • TV has what we can watch and when and how we watch • Also brings sports we might never normally watch - , • Become converted to • Reduces improved sumo wrestling armchair spectators participation?
Changing the characteristics of sport • Changing the format of play – • Changing the competition structure – • Changing the rules to simplify them – • Changing the rules to make game ‘flow’ – tennis tie breaks Champions League/ RU premiership American scoring – badminton/volleyball one-day/20:20 cricket
Professional performer - a commercial object? • Signs contract – • Can be • Brings in money through • Exploit image for company goals – • Financial rewards like a business ‘hired and fired’ advertising endorsements marketability based on results
Olympic ideals • Individuals performing • Not • Striving to win - • Taking part more important than • – for the love of sport teams/Nations fairly winning • Amateur
Olympism • Competing with spirit of Symbols: • Olympic • Olympic • Virtually gone due to needed to compete • IOC accept professional performers – sportsmanship rings oath financial support ‘amateur spirit’
Kreb’s cycle - Typical question At the 2008 Beijing Olympic Games, David Davies won the silver medal in the swimming 10 kilometre marathon event, in a time of 1 hour 51 minutes and 53.1 seconds. Explain how the majority of energy used during the race would be provided. (7 marks)
Kreb’s cycle • Carbohydrates - - broken down in series of reactions to • Called • Some energy released for • Fats (fatty acids) prepared through ready for in glycogen/glucose pyruvate glycolysis ATP resynthesis β -oxidation Kreb’s cycle mitochondria
Kreb’s cycle Acetyl Co- A • Pyruvate converted into • Enters • Hydrogen removed leaving • Some • Hydrogen to • Oxidised to • Releases large amounts of energy for Kreb’s cycle carbon dioxide ATP resynthesised Electron Transport Chain water ATP resynthesis
Aggression - Typical question Trait theories may be used to explain several psychological constructs. (a)Sport may increase or decrease the likelihood of aggressive behaviour occurring among competitors. How may trait theory be used to explain aggression in sport? (2 marks) (b)Use the frustration-aggression hypothesis to explain why this may happen. (2 marks) (c)Explain why incidents of aggression occur only occasionally in team games. (2 marks)
Aggression “Any form of behaviour directed toward the goal of harming or injuring another living being who is motivated to avoid such treatment” Aggression is: a behaviour/action; intentional; to cause harm; outside the rules;
Forms of Aggression • Instrumental –aggression used to increase chances of • Hostile - aggression with injury as • Constructive use of force in sport = • Channelled aggression – diverting aggressive feelings into winning main aim assertion useful actions
Instinct theory • Aggression • Builds up – needs to be • Displaced into sport rather than • Release = • Theory suggests most aggression is , but some is • as a means of control inherited released violence catharsis hostile instrumental Social learning
Frustration-aggression hypothesis aggression • Frustration leads to • Aggression comes from • In sport, prevents attainment of - leads to frustration, especially if • Aggression released – – but not always • But, not all leads to frustration opposition goals unexpected cathartic frustration aggression
Aggressive-cue theory • Not all frustration leads to aggression • Only occurs if certain present Such as: • Coach aggression • of behaviours • Certain or • Previous • Depends on learned cues encouraging Reinforcement sports objects experiences situation
Social learning theory • to be aggressive • of others • leads to • prevents Learn significant Observation repeating actions Reinforcement Punishment copying
Strategies to reduce aggression Strategies both for player and coach • Punish aggressive play • Reinforce assertive play • Reduce arousal • Avoid aggressive situation
Elite Athlete Support - Typical question To maximise the chances of winning medals at major championships, such as the Olympic Games, performers need the support of many organisations. Outline and explain the structure of the World Class Performance Pathway. (3 marks) Explain the support structures for elite performers provided by the National institutes of excellence, such as the English Institute of Sport. (4 marks)

Projectile motion – Typical question The flight of a golf ball is said to be parabolic. Explain the term parabolicand the main factors that limit the distance that a golf ball will travel in flight. (4 marks)
Projectile motion • Flightpath = parabola
Components • Motion of projectile has components • component • component two Vertical Horizontal
Projectile motion Vertical component Horizontal component Vertical motion affected by gravity – Horizontal motion is affected by friction – decreases negligible
Variations in vertical and horizontal components This causes the observed parabolic flight and affects the motion components as follows:
Projectile motion Factors affecting distance travelled: Speed of release Height of release Angle of release
