exam questions Flashcards
In the space provided, draw a graph of the force-length for muscle contraction and explain its
application to the starting position as indicated in the above dart-throwing progression
Damon starts his throw with his arm bent at the elbow which allows
optimal/resting/mid-range muscle length to occur in the triceps. 1
Above is due to the ability to engage/use maximum cross bridges. 1
Force is low when muscle is lengthened due to little overlap of actin and myosin. 1
Force is low when muscle is contracted (shortened) due to large overlap of actin
and myosin.
Define ‘relaxation’.
Definition includes reference to:
the reduction of anxiety/stress/tension/arousal levels
employing a relaxation activity to achieve the physical or
mental benefits, e.g. reducing heart rate.
Define the term ‘group cohesion’
Group cohesion is a term used to describe the extent to which a group
cooperates together.
Describe four strategies coaches could have used to ensure that positive group
cohesion occurred within their teams during their time in the hub.
Describes a strategy coaches use to ensure positive group cohesion 2
Makes a general statement about a strategy for group cohesion 1
Total 8
Describes any four of the following:
clearly communicate with players their roles and responsibilities during their time in
the hub
keep them updated with communication regarding the issues surrounding why they
are in the hub
have clear expectations of what is expected whilst in the hub
set challenging but realistic goals for the team as a whole and for individual
players. Players are involved in this process
being fair and consistent in dealing with the players in the team
prioritise team goals over individual goals
promote high levels of motivation to keep team focused
have regular team meetings – provides an opportunity for players to voice their
opinion
encouraging social interactions within the hub, e.g. a cards night, movie night,
dinners together
encourage regular contact with family and friends via video call
create smaller groupings to do activities and swap them around.
Sample response for 2 marks
Coaches are open and honest with communication (1 mark) so players are aware
of their individual and collective resp
Label the diagram below and explain how the principle from part (a) works to increase
the velocity of the boat.
Bernoulli’s Principle states the velocity of a fluid moving over an object
is inversely proportional to the pressure on the object, i.e. when the
velocity of a fluid moving over an object increases, it creates a
low-pressure system
the shape of the wing keel/hydrofoil takes advantage of Bernoulli’s
Principle
when the fluid moves over the keel, its velocity increases and creates
a low-pressure system on top of the keel
when the fluid moves under the keel, its velocity decreases and
creates a high-pressure system beneath the keel
high-pressure systems move to low-pressure systems, causing a lift
force
1–5
lift forces cause the boat to rise out of the water thus decreasing drag
Describe how Sinead could ensure ‘peaking’ occurs in her training
Describes method/s of ensuring peaking occurs in her training
(2 marks) 1–2 States method/s of ensuring peaking occurs in her training
(1 mark)
Total 2
Sample answers may include:
* periodisation is the breaking up of a training program into blocks of time
with specific objectives or goals that link to recovery for peaking
* tapering is the reduction in training volume and duration, and
increase/maintain training intensity in the lead-up to her event
List three ways in which Sinead could adjust her fitness training for the two weeks
before a marathon.
dentifies any three of the following adjustments:
reduces duration of training
reduces frequency of training
increases intensity of training
adds extra recovery sessions, e.g. pool running
includes strategies such as massage, rest days etc.
Would the golfer adjust their training program in the same way Sinead has to prepare
for a marathon? Justify your response
No 1
Subtotal 1
Justification may include the following:
golf is a low intensity aerobic activity
tapering is most beneficial for endurance athletes
Explain the biomechanics behind how the curveball moves away from a right-handed
hitter.
Explanation includes the following (1 mark per dot point):
applies an off-centre or eccentric force to the ball
Magnus force changes the flight path of the ball due to spin while
moving through the air
airflow around the spinning ball (boundary layer) going in the same
direction as oncoming air creates high velocity
areas of high velocity form a low-pressure system
airflow around the spinning ball (boundary layer) going in the opposite
direction as oncoming air creates low velocity
areas of low velocity form a high-pressure system
air moving from high to low-pressure causes the ball to move in the
same direction
identifies that the movement of air creates a lift/Magnus force
A recovery strategy Carlton employed for the team in their four-day break was having
sessions of pool running, similar to the image shown above. Outline two ways in which
this therapy would assist the player’s recovery
Outlines any two of the following:
water reduces weight bearing
less impact on muscles and joints
increases blood flow through active recovery
increases waste removal from muscles.
Name and outline two other recovery methods Patrick could have used as part
of his recovery
Examples of recovery methods:
Contrast therapy
alternating immersion in and out of hot and cold water
Massage
rubbing of the muscles/roller/massage gun
Cryotherapy
using ice packs/submerging in cold-water/use of a cryogenic chamber
Compression garments
wearing garments that fit tightly around the skin
Active recovery/stretching
low/moderate movement or stretching activities
Hyperbaric chambers
time in an oxygen-rich environment
For each recovery method in part (b)(i), outline a benefit to Patrick of using this
method.
Any the following benefits identified for part (b)(i):
Contrast therapy
helps increase blood flow in muscles
removes waste products from muscles or stimulation of the
lymphatic system
Massage
helps realign muscle fibres or reduces muscle tension
increases joint mobility and flexibility
helps increase blood flow in muscles
removes waste products from muscles or stimulation of the
lymphatic system
Cryotherapy
helps reduce blood flow to the muscles and reduces
inflammation/swelling
Compression garments
reduces the space for swelling and inflammation in muscles to occur
helps increase blood flow in muscles to remove waste products
and prevent venous pooling
Active recovery/stretching
helps increase blood flow in muscles to remove waste products
and prevent venous pooling
Hyperbaric chambers
decreases muscle inflammation
increases ability for removal of waste products
Leadership styles:
authoritarian
coaching a new team that has lacked discipline in the past
athletes may not be very experienced nor knowledgeable so require someone
to provide detailed instructions and structure
dangerous activities are being conducted – activity requires guidance and
strict supervision and following of rules and guidelines to avoid
injuries/accidents
time is limited – decisions need to be made immediately and followed by the
team
establishing authority (pre-season fitness activities) – establish authority,
respect and control when starting the new year to ensure compliance to
repetition and intensity, structure and organisation
in-season – coach may need to make his own decision to execute a winning
tactic to advance the team/athlete.
1–4
Negative impact of Authoritarian style – any one of the following:
lack of ownership or input by the athletes
not as much fun as the coach is too strict and the athletes may feel anxious
too many rules for athletes so they become disinterested
may not bring out the full potential of all athletes
task-oriented, not team-oriented
creates an inflexible environment
all decisions fall back on the coach, be it good or bad
not ideal for the experienced or intrinsically-motivated athlete.
Leadership styles:
laissez-faire
athletes are empowered and gain independence by having to make decisions
themselves which can increase their confidence and ownership within the team
when training is conducted in a relaxed atmosphere creating less pressure
which may improve outcomes or progression
athletes who are intrinsically motivated and experienced who have the skills
and expertise to train themselves
meets the needs of athletes who want to focus on participation, socialising
and enjoyment rather than winning at all costs
coach can step back and hand control over to the athletes to identify leaders
of the team during pre-season
develops athletes’ problem-solving capacity by allowing them to work out
strategies in mini games/drills which can be beneficial for game day
creates athletes’ initiative to allow them to step up and think outside the box.
1–4
PHYSICAL EDUCATION STUDIES 12 MARKING KEY
Negative impact of Laissez-faire style – any one of the following:
limited direction and skill progression, athletes may not have the skills or
expertise to develop or progress, no overall development plan
does not meet the needs of athletes who want to learn, improve performance
and win as well as athletes who are extrinsically motivated
athletes can waste time and fool around and may lead to safety issues
lack of direction or forward planning limits growth of athletes/team
cause cohesion problems amongst team/ athletes.
Leadership styles:
democratic.
emocratic – any four of the following:
athletes are experienced and can give direct input into direction of the team
there is plenty of time to allow for decisions or planning direction of training
used during the competition season to incorporate the team in
decision-making
when coaching an individual sport such as tennis
helps motivate athletes as they feel valued
females are more receptive to democratic style of coaching
when coaching junior teams who know how to play the game (not beginners).
1–4
Negative impact of Democratic style – any one of the following:
may cause division in the team as only certain athletes are listened to
team progression may decline as there may be too many opinions on the
direction the team should take so athletes argue.
Describe why Campenaerts slept in the tent. Identify and outline four physiological
adaptations that would improve his chances of breaking the world record.
Description may include:
can develop adaptations that benefit his aerobic event
sleeping in an altitude tent provides less oxygen: the body becomes
more efficient in using oxygen
training can continue at sea level (‘live high, train low’).
