1(d)(i)       1. Delayed onset of muscular soreness/muscular pain 24-48
                 hours after performance.
              Causes: (submax 2)
              Based on current evidence, it appears that;
              2. DOMS is due to tissue injury caused by excessive mechanical
                 forces being applied to the muscle and connective tissue
              3. May occur because of structural damage within muscle
                 membranes /healing of damaged fibres
              4. Often the result of eccentric work
              5. Changes in the range of movement
              6. Changing training methods/new exercises/range of motion
              7. Increases in intensity
              8. Poor preparation or warm up can contribute

              Effects: (submax 2)
              9. The breakdown of muscle proteins causes an inflammatory
                  response
              10. This is created as fluid shifts from blood plasma to damaged
                  tissues.
              11. Local pain receptors are then stimulated by this excess
                  fluid/pain
              12. An adequate cool down can reduce the effects

              Cannot score all four from one subsection (causes or effects)             (4)

           Strategy – appropriate warm up
           PB – muscle becomes more compliant when it’s warm, reducing risk
           of injury


            Strategy             1. Apply progression to avoid sudden /
                                    rapid increases in intensity/avoid

            Strategy             5. Aerobic training
            Physiological        6. Aerobic training increases capillarisation
            benefit                 within the muscle, which allows greater
                                    and faster saturation of blood, carrying
                                    oxygen and nutrients
            Strategy             7. Undergo an active cool down
            Physiological        8. Speeds up recovery allowing the period
            benefit                 of DOMS to be shorter/increased blood
                                    flow to damaged muscles
            Strategy             9. Ice baths
            Physiological        10. Reduces the swelling within the
            benefit                 myofibrils and encourages a faster
                                    recovery/increasing blood flow to area
            Strategy             11. Anti inflammatory tablets
            Physiological        12. Reduces the swelling within the
            benefit                 myofibrils so removing the discomfort,
                                    however it does not speed up recovery
                                    so training will be no more frequent.
            Strategy –           13. Appropriate nutrition
            Physiological        14. Speeds up muscle repair / reduces
            benefits                 DOMS

              3. Airflow below ball in same direction as spin

                 effect
              6. Ball will move from area of high pressure to low pressure
              7. Which pushes ball down
              8. So ball dips quicker
              9. Therefore ball has to be hit slightly higher initially to stop it
                 hitting the net
              10. Can be hit harder and still be more easily kept in the court.              (6)

3(e)          1.    The acceleration of a body/the rate of change of momentum
                    of a body is proportional to the force causing it and takes
                    place in the direction in which the force acts/F=ma.
              2.    As the ball is passed, the player applies a force in the
                    direction towards his team mate.
              3.    The resultant acceleration is positive/the ball speeds up
              4.    As the ball travels along the ground, it begins to slow down.
              5.    Therefore the resultant force must be acting against the
                    direction of travel/friction/air resistance is slowing the ball
                    down.
              6.    When his team mate stops the ball, he applies a force
                    against the motion of the ball.
              7.    The force reduces the momentum of the ball, so the ball
                    comes to rest.                                                           (6)

4(a)(ii)    1.   Discus must be angled to achieve lift.
            2.   Air flow over top of discus has high velocity = low pressure
            3.   Air resistance along the bottom of the discus has lower
                 velocity = high pressure
            4.   This creates a pressure difference
            5.   Objects move from high pressure to low pressure = lift
            6.   The greater the velocity of the object the greater the air flow,
                 the greater the lift
            7.   Optimum angle of attack increases lift, whilst minimising drag.
            8.   Minimising ‘wobble’ of the discus maintains a more
                 aerodynamic position which means lift force is less affected

                  Interaction between factors is important
                  Such as:
                  Inherited genetics with a sedentary lifestyle would probably not lead to being an
                  elite athlete
                  Access to high quality facilities without inherited genetics is also unlikely to lead
                  to being an elite athlete.

Aerobic glycolysis can produce up to 36/38 molecules of ATP from 1 molecule of glucose (accept 32/34 as aerobic yield) 3. The lactic acid energy pathway/anaerobic glycolysis can produce 2/4 per glucose molecule. 4. ATP-PC system produces one ATP (2) Question Answer Mark Number 1(a)(ii) Max of 5 from; 1. The first stage is glycolysis 2. Glucose is broken down in the presence of glycolytic enzymes 3. Yield is 2 ATP 4. And (2) pyruvic acid 5. The pyruvic acid in the presence of oxygen is further broken down 6. Pyruvic acid enters the mitochondria 7. Here it is broken down into acetyl -co enzyme A 8. The next stage is krebs cycle/oxaloacetic acid/this reacts to produce citric acid 9. Positive hydrogen ions are produced in the krebs cycle 10. The cycle creates sufficient energy to produce 2 additional ATPs 11. The hydrogen ions are transported to the electron transport chain/NADH/FADH 12.

Reduce muscle temperatures 10. Replenish ATP / CP / Glycogen stores. (4) 3
  • 4. Question Answer Mark Number 1(d)(i) 1. Delayed onset of muscular soreness/muscular pain 24-48 hours after performance. Causes: (submax 2) Based on current evidence, it appears that; 2. DOMS is due to tissue injury caused by excessive mechanical forces being applied to the muscle and connective tissue 3. May occur because of structural damage within muscle membranes /healing of damaged fibres 4. Often the result of eccentric work 5. Changes in the range of movement 6. Changing training methods/new exercises/range of motion 7. Increases in intensity 8. Poor preparation or warm up can contribute Effects: (submax 2) 9. The breakdown of muscle proteins causes an inflammatory response 10. This is created as fluid shifts from blood plasma to damaged tissues. 11. Local pain receptors are then stimulated by this excess fluid/pain 12. An adequate cool down can reduce the effects Cannot score all four from one subsection (causes or effects) (4) 4
  • 5. Question Answer Mark Number 1(d)(ii) Max of two for strategies or physiological benefits. Strategy – appropriate warm up PB – muscle becomes more compliant when it’s warm, reducing risk of injury Strategy 1. Apply progression to avoid sudden / rapid increases in intensity/avoid eccentric contractions Physiological 2. Less likely to experience myofibril benefit damage / trauma. Strategy 3. Utilise cross training Physiological 4. Provides a variety of training positions / benefit range of movements. Strategy 5. Aerobic training Physiological 6. Aerobic training increases capillarisation benefit within the muscle, which allows greater and faster saturation of blood, carrying oxygen and nutrients Strategy 7. Undergo an active cool down Physiological 8. Speeds up recovery allowing the period benefit of DOMS to be shorter/increased blood flow to damaged muscles Strategy 9. Ice baths Physiological 10. Reduces the swelling within the benefit myofibrils and encourages a faster recovery/increasing blood flow to area Strategy 11. Anti inflammatory tablets Physiological 12. Reduces the swelling within the benefit myofibrils so removing the discomfort, however it does not speed up recovery so training will be no more frequent. Strategy – 13. Appropriate nutrition Physiological 14. Speeds up muscle repair / reduces benefits DOMS Strategy 15. Appropriate warm up Physiological 16. Muscle becomes more compliant benefits when it’s warm, reducing risk of injury, increased ROM. (4) (Total 25 marks) 5
  • 6. Question Answer Mark Number 2(a) Definition Chemical energy 1. Energy that is released from a chemical compound and created by way of chemical processes / comes from food/metabolic reaction. Example 2. Food groups (fats, carbohydrates, proteins ) converted into chemical energy. / stored as ATP or PC, chemical compounds/metabolic reactions eg break down of glycogen or phosphates Definition Kinetic Energy 3. Energy that is being utilised and is producing movement or work Example 4. ATpase breaks the ATP compound and facilitates muscular contraction which is kinetic energy. (any movement example) Definition Potential energy 5. Energy that has the “potential” to provide movement or work/or by virtue of position/stored energy ready to use Example 6. Stored ATP or PC both have the potential to provide energy when broken down/bike at top of hill/stored glycogen (carbohydrates) (6) Question Answer Mark Number 2(b)(i) 1. Weight loss would be through water / fluid loss/sweating 2. Dehydration 3. If fluid loss is greater than fluid input 4. Thermo regulation / overheating 5. Climatic conditions 6. Inappropriate clothing 7. Insufficient hydration pre and during an event (4) 6
  • 7. Question Answer Mark Number 2(b)(ii) 1. Bodies inability to regulate temperature = overheating 2. 2% loss of body weight = 10% loss in performance or similar figures 3. 5% loss of body weight = 25% loss in performance or similar figures 4. 8% loss of body weight = potentially fatal 5. reduction in physiological function e.g. VO2 max 6. Loss of electrolytes 7. Increase viscosity of the blood 8. Increased blood pressure 9. Cellular donation of water to the blood resulting in “shutdown” of many cells 10. Leading to greater fluid loss and severe dehydration leading to further overheating 11. Increased HR 12. Decreased SV 13. Decreased Q 14. Recovery can take several days. 15. Severe cases can lead to death. 16. Feeling dizzy/faint 17. Feeling tired/weak/fatigued / loss of coordination 18. Colouration / concentration of urine (7) Question Answer Mark Number 2(c) 1. When the action potential/impulse reaches the sarcomere the motor end plates are depolarised. 2. Depolarisation causes Ca2+ to be secreted (from the “T” vessels within the cells sarcoplasm / saracoplasm reticulum) 3. Calcium binds to troponin 4. Tropomyosin complex (which blocks the binding sites) moves/changes 5. This leaves active sites exposed on the Actin. 6. The result is that the actin and myosin attach/cross bridge formed / Actin is attracted to myosin 7. Myosin cross bridge is energised by the breakdown of ATP 8. Sarcomere gets smaller/z bands change distance/actin slides over myosin 9. Myosin heads tilt towards centre of sarcomere/power stroke 10. This cross bridge is immediately broken and then recreated as long as calcium is present 11. Ratchet mechanism 12.

  • 9. Question Answer Mark Number 3(d) Top-Spin Appropriate labelled and explained diagram is acceptable 1. Airflow over top of ball in opposite direction of spin 2. Airflow on top of ball has low velocity therefore higher pressure 3. Airflow below ball in same direction as spin 4. Airflow below ball has high velocity and therefore lower pressure 5. Resultant vertical force acting downwards on ball / Magnus effect 6. Ball will move from area of high pressure to low pressure 7. Which pushes ball down 8. So ball dips quicker 9. Therefore ball has to be hit slightly higher initially to stop it hitting the net 10. Can be hit harder and still be more easily kept in the court. (6) Question Answer Mark Number 3(e) 1. The acceleration of a body/the rate of change of momentum of a body is proportional to the force causing it and takes place in the direction in which the force acts/F=ma. 2. As the ball is passed, the player applies a force in the direction towards his team mate. 3. The resultant acceleration is positive/the ball speeds up 4. As the ball travels along the ground, it begins to slow down. 5. Therefore the resultant force must be acting against the direction of travel/friction/air resistance is slowing the ball down. 6. When his team mate stops the ball, he applies a force against the motion of the ball. 7. The force reduces the momentum of the ball, so the ball comes to rest. (6) (Total 25 marks) 9
  • 10. Question Answer Mark Number 4(a)(i) Lift Air Resistance Drag Direction of travel 1. 1 mark for correctly identifying lift. 2. 1 mark for correctly identifying drag in relation to throw. 3. 1 mark for correctly identifying air resistance in relation to throw. (3) 10
  • 11. Question Answer Mark Number 4(a)(ii) 1. Discus must be angled to achieve lift. 2. Air flow over top of discus has high velocity = low pressure 3. Air resistance along the bottom of the discus has lower velocity = high pressure 4. This creates a pressure difference 5. Objects move from high pressure to low pressure = lift 6. The greater the velocity of the object the greater the air flow, the greater the lift 7. Optimum angle of attack increases lift, whilst minimising drag. 8. Minimising ‘wobble’ of the discus maintains a more aerodynamic position which means lift force is less affected 9. Optimum angle of release will also contribute to optimising lift force (6) Question Answer Mark Number 4(b) Sub max of 2 1. 1st law: every body at rest, or moving with constant velocity in a straight line, will continue in that state unless compelled to change by an external force exerted upon it. 2. There must be a force acting upon the ball because the velocity is not constant/the velocity is not constant because friction/air resistance is slowing the ball down. 3. The force applied to the ball by the player kicking it causes it to move from being at rest/the force applied by a player controlling/kicking the ball causes its motion to change. Sub max of 2 4. 3rd law: for every action, there is an equal and opposite reaction 5. The force exerted on the ball by the player is equal but opposite to the force exerted on the player by the ball. 6.

  • 13. Question Answer Mark Number 5(a) 1. Positive reinforcement will strengthen S-R bond i.e. coach congratulates performer after they display the desired technique for a set shot in basketball. 2. Negative reinforcement will strengthen the S-R bond by either removing an unpleasant stimulus after a successful performance/action/response or removing a pleasant stimulus after an incorrect performance/action/response e.g. a basketball coach calls ‘well done’ to a performer every time they have performed the set shot correctly but says nothing after an incorrect technique. 3. Punishment can break the S-R bond e.g. a teacher gives a penalty against a team during a football lesson because a student uses foul language in an attempt to eradicate it / yellow & red cards. 4.
