0 4 . 2 Use Figure 2 to identify the type of training method each athlete is using in the
exercise session. Justify your answers.
[4 marks]
Training method used by athlete 1
Continuous (training) (1)
Justification
As after initial increase heart rate reaches steady state/remains elevated in order to maintain this
intensity for the majority of the exercise period (1)
Training method used by athlete 2
Interval / circuit/ weight / fartlek (training) (1)
Justification
As graph indicates fluctuations in heart rate throughout exercise session/exercise intensity must vary
during the session, the increases in heart rate indicating more intense parts of the session/drop in
heart rate lower intensity/periods of recovery within session (1).
Justification for athlete 2 must refer to a number of fluctuations in heart rate.
Accept HR for heart rate as this is shown on Figure 2.

Accept other appropriate explanations of the data in heart rate that explain the training method used
by each athlete during the exercise session.

Sub-max 1 mark
Award one mark for each of the following points.
AO2
Reduced gaseous exchange in the lungs / oxygen transport to the muscles (1)

This decreases the athlete’s ability to utilise oxygen in energy production / work aerobically (1). This
means they have less energy for their activity / slower time / fatigue quicker (due to working
anaerobically) (1).

0 6 It is important for sprinters to push off the blocks effectively to achieve a fast start.
Using Newton’s first and second laws of linear motion and knowledge of the
neuromuscular system, analyse how a sprinter is able to achieve a fast start.
[8 marks]
AO1 – Knowledge of Newton’s first and second laws of linear motion and the neuromuscular
system
Newton’s first and second laws – Eg First law is the law of inertia. Inertia is a body’s reluctance to
change its state of motion. A force is required to overcome inertia. Second law is the law of
acceleration, the rate of change of momentum of an object is directly proportional to the force
causing the change. Any change in momentum takes place in the direction the force was applied.
Force = mass x acceleration.
Neuromuscular system – Eg three muscle fibre types, type I, type Ia, type IIx. Muscle contraction
brought about by the recruitment of muscle fibres. Spatial summation is when the strength of a
contraction changes by altering the number of size of motor units. Wave summation is where there is
a repeated nerve impulse with no time to relax so a smooth, sustained contraction occurs. This is a
tetanic contraction. Muscle fibres form a motor unit (with motor nerve), each muscle fibre in the unit
contracting or relaxing at the same time. This is according to the all-or-none law. There are different
sizes of motor unit.
AO2 – Application of Newton’s first and second law and the neuromuscular system to a
sprinter
Eg The sprinters current state of inertia is stationary; to alter this state of inertia the sprinter needs to
apply a muscular force by contracting his leg muscles in order to overcome his inertia so that he can
leave the blocks, moving from a stationary position to begin to run.
By varying the force of his muscles’ contraction and the number of motor units recruited the sprinter
can cause a change in momentum from stationary to moving. The sprinter applies a force against
the blocks and then the ground to generate the required momentum to move forward down the track.
It would be beneficial to the sprinter to have a high percentage of fast twitch fibres type IIx. The
sprinter will recruit large, fast twitch motor units in the leg muscles to generate the force required to
overcome inertia, the sprinter will use spatial summation, varying the number of motor units recruited
throughout the muscle to allow the fibres in each unit to relax whilst others are contracting to provide
the necessary force.
AO3 – Analysis/Evaluation of how the sprinter is able to achieve a fast start
Eg The greater the muscular force that the sprinter can apply against the blocks, the more readily the
body will alter its state of inertia, allowing the sprinter to move more quickly out of the blocks. By
varying the force of his muscles’ contraction, the greater the force he generates, the greater the
acceleration away from the blocks, giving him a better start than his competitors.
If the sprinter increases the frequency of stimulation of the muscle fibres in the motor unit such that
the next impulse reaches the muscle before it has completely relaxed from the previous the resulting
force is greater, hence the sprinter may use wave summation to increase the force of the muscle
contraction further, generating a greater force and therefore greater acceleration according to
Newton’s second law.
Accept other appropriate analysis of Newton’s first and second laws of linear motion and the
neuromuscular system in enabling a sprinter to achieve a fast start.

9 In most sports, coaches can give feedback during a break in play.
Identify and describe two different types of feedback that a coach could give
during a break in play. Give a sporting example to support each answer.
[4 marks]
(AO1) Positive feedback can be given by the coach, praising / recognising what is going well (1)
(AO2) e.g. taking a quick corner catching the defence out so the goal was scored (1).
(AO1) Negative feedback can be given by the coach providing criticism/ information on what is going
wrong/ weaknesses during play (1) (AO2) e.g. the team keep giving away free kicks (1).
(AO1) Knowledge of performance can be given by the coach to explain why a technique is working
or not working (1) (AO2) eg if a player’s shots were going over the goal the coach would explain the
fault in technique causing this, ie weight on the back foot (1).
1 1 Vicky is a badminton player. She has recently begun to play tennis.
Explain the impact of negative and zero transfer of learning on Vicky’s progress in
tennis. Give examples from badminton and tennis to support your answer.
[4 marks]
Negative transfer sub max 2 marks The skills Vicky has learnt in badminton will hinder the learning of skills / techniques in tennis (1) for example, in badminton forehand shots are played with a flexible wrist but in tennis the wrist should be firmer (1).
Zero transfer means that some badminton skills will have no impact on Vicky’s tennis performance,
due to the differences in the skill (1). For example, in badminton, players serve underarm but the
serve is overarm in tennis / no top spin in badminton (1)
1 2 Figure 4 shows a player taking a corner kick in football.
1 2 . 1 Classify the corner kick in football using the following continua: • open – closed • self-paced – externally paced. Justify your answers. [2 marks]
Open-closed: closed/towards closed end of continuum because the opposition cannot directly
interfere with the player taking the corner (1).
Self-paced – externally-paced: self-paced/towards self-paced end of continuum because the player
decides when they want to kick the ball (1).
1 2 . 2 Describe the high – low organisation skill continuum.
[2 marks]
his continuum refers to how easily a skill can be broken down / the nature of phases / subroutines
that make up a skill (1).
Low organisation skills tend to be made up of discrete phases / subroutines / can easily be broken
down / phases can be practiced separately (1)
High organisation skills tend to have phases / subroutines that cannot be easily broken down / the
phases of the skill cannot be practiced separately (1).
2 . 3 Give one example of a low organisation skill in football.
[1 mark]
Taking a penalty/passing the ball/taking a goal kick/making a shot/throw in (1).
Accept any other suitable example of a low-organisation skill in football
