what is visual guidance ?
when the performer can see the skill being performed or practiced
what are the different types of visual guidance ?
- demonstration
- image
- video
- observation
how is demonstration used for visual guidance ?
- a coach or another performer demonstrates the skill or movement, usually highlighting key aspects that are important
how are images used for visual guidance ?
there’s a photo, diagram, or drawing of the skill
how are videos used for visual guidance ?
either an example of the skill being performed or a recording of the performer’s own performance
how is an observation used for visual guidance ?
observing a game or another performer
what does visual guidance show ?
the skill as a whole movement, broken down into steps, or applied within a real situation
what are the positives of visual guidance ?
- helps learners who are at the early stages of learning the skill and have never seen or experienced the skill
- helps skilled performers refine specific elements of a skill
give an example of an athlete who used visual guidance ?
Julius Yego, 2015 javelin world champion learnt to do the javelin by watching videos online
how does visual guidance technology help support athletes ?
- breaks down complex skills into series of static movements
- athletes can record and playback their performances to see when skills when were performed effectively
- athletes can overlay multiple performances to compare
- athletes can compare their own performance to another athletes, elite vs regular
who gives verbal guidance ?
is given by an observer after watching your performance
what are the different types of verbal guidance ?
- coaching points - given by coach relating to technique of performance
- feedback - given by coaches
- peer feedback - given by peers
- questioning - by the coach so the performer is prompted to self evaluate
why does feedback need to be constructive ?
to help the performer improve their skill
why does feedback need to be specific and accurate ?
so the performer knows exactly what and how to improve
when is verbal feedback given ?
before, during, and after practice or a performance
give an example of constructive feedback in netball
telling the netballer to open their fingers wider when doing a chest pass to have more power and control
give an example of unhelpful feedback in netball
telling the netballer they need to pass the ball better next time
what is manual guidance ?
when a performer is physically guided or supported by the coach
what is manual sometimes referred as ?
physical manipulation
give an example of manual guidance
coach supporting a gymnast doing a handstand
when is manual guidance used ?
during practice
what is mechanical guidance ?
when a piece of equipment or an aid is used to help a performer learn and practice a skill
give an example of mechanical guidance
float in swimming to develop leg action
why is mechanical guidance useful ?
it allows the performer to develop the full feeling of the full movement and gain confidence
when is mechanical guidance used ?
at early stages of learning
how does mechanical guidance help with elite sport ?
it involves high tech methods
what is intrinsic feedback ?
the physical feel of the movement as it’s being performed, what is felt by the performer
what is extrinsic feedback ?
provided by external sources, during or after a performance
who can give extrinsic feedback ?
- teachers
- coaches
- peers
- teammates
- scores / results
what are the 2 different types of feedback ?
- knowledge of results
- knowledge of performance
give an example of extrinsic feedback
a basketball player can hear verbal feedback from a coach
what is knowledge of results ?
focuses on the end of the performance , like the performers score, time or position, factual results
what is knowledge of results sometimes referred to ?
terminal feedback
what is knowledge of performance ?
focuses on how well the athlete performed, not the end result
give an example of knowledge of performance ?
receiving your personal best time in a race despite coming last
what are the advantages of intrinsic feedback ?
- helps performer focus on the feel of a skill
- helps performer solve problems themselves
- helps performer develop skills independently
- give performer more time to practice
what are the advantages of extrinsic feedback ?
- provides new or additional guidance
- helps performers to identify problems
- offers solutions to problems
- prevents performers from reaching a dead end
what type of feedback to beginner athletes usually benefit more with ?
extrinsic feedback - as it helps them acquire basic skills
what type of feedback to elite athletes use more often as they improve ?
intrinsic feedback - to help refine and master skills
what is positive feedback ?
feedback used when the performer achieves the intended outcome
give an example of positive feedback
rugby player passes the ball and receives positive feedback when receiver successfully catches the pass
what is negative feedback ?
when a performer does not achieve the intended outcome
give an example of negative feedback
when a netballer shoots and misses, they receihve negative feedback
how does negative feedback help improve the performer ?
it encourages the performer to adjust their technique
how does positive feedback improve the performer ?
it is used as a motivation tool
when would positive feedback be used ?
if a footballer is losing a match, giving positive feedback can keep them motivated, encourages them
when would negative feedback be used ?
swimmer, during trainer to improve technique
when would knowledge of results be used ?
netball - the score allows you to see how well you did and what you need to improve
when would knowledge of performance be used?
knowing what your time in a race was to see if you got a personal best, even if you lose the race to keep you encouraged
when would extrinsic feedback be used?
a coach in basketball telling you how to improve during a match
when could intrinsic feedback be used ?
in rounder, feeling how hard you hit the ball and seeing how good the hit was
what is verbal guidance ?
when you’re given instructions, being given key skill points
when is guidance effective ?
- combined with verbal guidance
- focused on main points in the skill
- delivered quickly
- concise
- easy to copy
- clear
- easy to understand and put into practice
- skill ability is suited to ability of the athlete
- skill ability is relative to the age of the athlete
what is guidance ?
giving the athlete advise on what they should do and support or help to improve performance, by teachers or coaches
what are the 4 types of guidance ?
- visual
- verbal
- mechanical
- manual
what is arousal ?
the level of activation and alertness experienced by a performer
give an example of arousal
a judo player having a higher arousal before a bout, and then having low arousal levels hours after the competition has finished
what is the inverted ‘U’ theory ?
a theory that suggests that :
- sporting performance improves as arousal increases but there is a threshold point, any increase in arousal beyond the threshold point will worsen performance
what is under-arousal ?
when the performer has low arousal levels, resulting in the performance usually being low - also known as boredom
give an example of when under-arousal may occur ?
when an elite tennis player is playing a lowly ranked opponent
what is optimum arousal ?
at medium arousal levels, when performance peaks
give an example of optimum arousal
when a boxer gets themselves into the right zone to perform their best
what is over-arousal ?
a high arousal level, or panic - performance quality deteriorates
give an example of over-arousal
a footballer performing poorly when their team is losing 3-0 so starts to panic
give an example of when arousal levels may change during a game
- half fly in rugby needs high levels of arousal when making a big hit compared to taking a penalty kick, when calmness is ideal
what is imagery ?
a mental or psychological technique where the performer visualizes themselves being successful in their performance
give an example of how imagery may be used
- performers recreating a good performance in their mind
- performers ‘make up’ a positive new experience, e.g before taking a penalty, a footballer visualizing the ball hitting the bag of the net
what is mental rehearsal ?
where the performer pictures themselves executing a skill in their mind, focusing on the specific stages and the correct techniques
give an example of mental rehearsal
a trampolinist mentally rehearsing a backwards somersault before performing the skill
how does using all senses improve imagery ?
it makes the imagery more vivid
give on example of how sight may improve imagery ?
a javelin thrower pictures how far the javelin will travel
give an example of how hearing may improve imagery ?
archer hearing the arrow hitting the target
give an example of how touch may improve imagery ?
gymnast touching the bars
give an example of how smell may improve imagery ?
swimmer smelling the chlorine in a pool
give an example of how taste may improve imagery ?
rower tasting salt in the air
how does imagery help the performer ?
- builds confidence
- reduces anxiety
- provides focus
- improves results
- overcomes problems
what is a physical and psychological process ?
a physical and psychological process, affects the body, and the body and mind are interlinked so it affects how the athlete feels
what is breathing control ?
a physical and psychological process which helps performers breathe steadily from the diaphragm to reduce anxiety
how do people breathe when they are anxious ?
from their upper chest, breathing is rapid and shallow
what is self talk ?
a psychological process which is the voice in our heads, telling ourselves about a situation
give an example of positive self talk
“i can run faster”
give an example of negative self talk
” i’m no good at running”
when do performers use self talk ?
when they are learning new skills or are in challenging situations during a performance
what are are the different parts of the respiratory system ?
- nasal cavity
- mouth
- trachea
- bronchus
- bronchioles
- alveoli
- diaphragm
- lung
describe airs journey in the body ?
- air enters the body and is warmed as it travels through the mouth and nose
- it then enters the trachea
- the trachea divides into two bronchi. One bronchus enters each lung
- each bronchus branches out into smaller tubes called bronchioles. Air travels through these bronchioles
- at the end of the bronchioles, the air enters one of the many millions of alveoli, where gaseous change takes place
what is breathing ?
the term given to the process of taking air into and out of the lungs
what are the 2 important structures for breathing ?
- diaphragm
- intercostal muscles
what is the diaphragm ?
a sheet of muscles that separates the chest cavity from the rest of the body
what are intercostal muscles ?
found in-between ribs, control rib movement
what is inspiration ?
breathing in
what happens to the diaphragm when you breathe in ?
it contracts and moves downwards
what happens to the intercostal muscles when you breathe in ?
contract and move the ribs upwards and outwards
what happens to the chest due to the movement in the diaphragm and intercostal muscles when breathing in ?
the size of the chest increases, and decreases the air pressure inside of it, which sucks air into the lungs
what happens when expiration begins with breathing in (inspiration) ?
inspiration is assisted by the pectoral muscles and the sternocleidomastoid to help lift the ribs up even further
what is expiration ?
breathing out
what happens to the diaphragm during expiration ?
it relaxes and moves back into its domed shape
what happens to the intercostal muscles during expiration ?
relax, so the ribs move inwards and downwards under their own weight
what happens to the chest size due to the way
the diaphragm and intercostal muscles moves during expiration ?
it gets smaller, which increases the air pressure in the chest which forces air out of the lungs
what happens with expiration during exercise ?
the passive process of relaxation becomes active as the abdominal muscles pull the ribs downwards and inwards even further
where does gaseous exchange take place ?
in the alveoli, in the lungs
how does gaseous exchange take place ?
diffusion
how does diffusion work in the alveoli ?
the alveoli is surrounded by capillaries so carbon dioxide and oxygen diffuse between the air in the alveoli and blood in the capillaries
what is diffusion ?
the movement of gas from an area of high concentration to an area of low concentration
where is there a high concentration of oxygen in the body ?
the alveoli
where is there a low concentration of oxygen in the body ?
the blood
