Q

what is the alactatcid ATP/PC system

A

after movement, ATP forms ADP

creatine phosphate is broken down to form creatine and phosphate and when combined with ADP it forms ATP

Q

what sport is the alactatcid ATP/PC system best suited for

A

due to the high speed of ATP production and the short duration of the fuel, ATP/PC is dominant for activities that require explosive muscular contractions over short times such as;

  • 100m sprint
  • discus
  • javelin
  • high jump

Q

duration the ATP/PC can operate for + cause of fatigue

A
  • fuel will be depleted in 8-12 seconds
  • -> creatine phosphate can be fully restored within 2 minutes (30sec-2minutes)
  • near maximal effort, fatigue is caused by inability to continually resynthesises ADP from CP because CP is quickly exhausted
  • -> why we are unable to run at maximal effort for longer than 100m

Q

what is the lactic acid system

A

after 8-12 seconds of maximal exercise and Cp supplies are exhausted, ATP will still need to produce energy where sufficient oxygen is not available for longer duration sports. the body needs a different fuel such as immediate sugar levels (glucose) that are circulating in the blood, liver and muscles

  • excess glucose stored in liver or muscle is called glycogen
  • process of using glycogen or glucose as fuel is called glycolysis

Q

cause of fatigue in lactic acid system

A

when lactic acid levels build up within muscle cells. it is caused by the rate of lactic removal because it is accumulated quicker than it can be removed
- high levels of lactic acid can cause deterioration in performance but moderate ones enhance performance as lactic acid is a source of fuel
lactic acid = lactic ion (lactate) and hydrogen ion
–> hydrogen is the acid part that impairs body from performing
–> lactate is fast fuel because it is easy to remove from blood

Q

process of recovery + rate of recovery for lactic acid

A

ROR : 30-60mins
post exercise : lactic acid diffuses from muscle into bloodstream, where in the liver it is reconverted into glycogen and can be used again as fuel

Q

what is aerobic system

A

physical activity which lasts longer than a minute requires the presence of oxygen-rich blood to continue muscular contractions
–> called aerobic metabolism because glucose (carbohydrates, sugar) and fat (sometimes protein) is broken down in the presence of oxygen to produce ATP

Q

cause of fatigue in aerobic system

A
  • decrease of blood glucose and muscle glycogen
  • when there is an exhaustion of carbohydrates and fat becomes the predominant fuel, it is called ‘hitting the wall’
    fatigue happens because fat requires more oxygen for metabolism of energy
    –> increases temperature + respiratory rate for athletes

Q

what is progressive overload

A

the gains in adaptation occurs only when training load is greater than normal and becomes progressively increased as improvement in fitness occurs. as the body becomes familiar with a particular of level training stress, it adapts to it and further training at the same level will fail to sufficiently stress the system

Q

what is muscle group specificity

A

muscle groups used in performance needs to be the same muscle group trained during training
- this is because the body will ‘recruit’ the type of muscle fibres most suitable for the task
E.g. 100m sprint, white fibres (fast-twitch) are required to adapt the most

however skills that may be easier to execute that involves large body movements (e.g. running + weightlifting) requires increase levels of arousal to be optimal

81
Q

what does optimal arousal largely depend on

A

individuals personality + factors that include;

  • self expectation
  • expectations of others
  • experience
  • financial expectations
  • level of competition
  • degree of difficulty
  • skill finness
82
Q

over arousal

A

over arousal results in athlete unable to perform required performance with precision because they are excessively tense and unable to concentrate

  • it can be characterised by anxiousness or apprehension, reflecting excessive concern about performance
  • -> leads to muscular tension and possibly mental confusion
83
Q

what is cognitive stage

A

at this stage, athletes make errors which are frequent and often large
coaches need to avoid “information overload” which could confuse learner
- learners will make mistakes, awkwardness and some disorientation which is why it is important for them to receive feedback

84
Q

what to do if cognitive learner experiences difficulty

A

skills can be broken down into smaller movements for practice
- drills are often reinforced to improve learners coordination and feel for the desired movements

85
Q

what is the requirements of the cognitive stage

A

the fundamental requirement in this stage is that the athlete gains an understanding of the task required which involves;

  • knowing what to do and an insight about how to
  • conceptualism of the ability to generate a clear mental picture of task
  • demonstrations, pictures, videos and instruction can highlight teaching points for learners
86
Q

what is associative stage

A

athletes experience success with a decreasing number of errors. learner has identified what the skill is, needs to repeat the movement to enhance synchronisation of their mind and muscles

87
Q

what are the requirements of associative stage

A

athletes are able to understand the principles and mechanics of the movement required and begins to learn anticipation

  • able to identify errors and at times correct themselves
  • skills may be executed but not to the speed or distance required
    e. g. basketball player develops ability to dribble ball from right to left but unable to dribble the speed of elite athletes
88
Q

what is the autonomous stage

A

athletes make occasional errors, which can be identified by the athlete themselves and at times adjusted mid-performance
E.g. diving
the most important feature is their ability to attend to other cues while giving little thoughts to how to perform their skill
E.g. netball, the problem will not be how to pass the ball but who to pass it to and what type of pass considering the position of the defence
–> less concentration needed and athlete can focus more on strategy + tactics

89
Q

what is autonomous stage categorised as

A

looking automatic and consistent

  • athlete has consolidated many discrete skills (subroutines)
  • movement is fluent as subroutines sequence blend, referred as temporal patterning
  • -> the movement looks good because it is efficient with the muscle groups and is working in order and producing only necessary movements required
90
Q

what are the characteristics of skilled performers

A
  • kinaesthetic sense
  • anticipation and timing
  • consistency
  • technique
91
Q

what is kinaesthetic sense

A

refers to the ability to make adjustments during performance, usually as a result of internal feedback

92
Q

what is an example of kinaesthetic sense

A

basketball : adjusting their shot after being fouled to ensure the shot still is successful

93
Q

ability to predict what is likely to occur
predicting movements from their opponents or team members mean that they are able to respond appropriately in the required time to successfully execute skills required

94
Q

example of anticipating and timing

A

tennis player anticipates a backhand down the line after reading body position of their opponent

95
Q

what is consistency

A

ability to perform skills at a high standard for a regular basis

be more consistent as they fatigue compared a performer who is not skilled

96
Q

what is technique

A

ability to perform movements that are safe, efficient and effective
–> important in developing strategies and tactics as they are not focused on the execution of the skill
this also contributes to the decrease of injuries throughout seasons

97
Q

what are objective performance measures

A

these are measures recorded using instruments such as measuring tapes or stop watches making data more credible by eliminating guesswork
a completely objective measurement occurs when judges apply the same criteria to measure performance and do not need to interpret information

98
Q

example of highly objective measuring

A

high jump events : same measuring scale is used to determine height jumped
running events : speed measurements using stop watches or electronic timing, or distance measurements provide reliable information because devices are accurate

99
Q

example of slightly objective measuring

A

team sports : need to be appraised by competent officials

100

it refers to the standard or qualities that are used for judging the value of a performance
there is;
- personal judging criteria
- prescribed judging criteria

105
Q

what is personal judging criteria

A

  • continuous (uniform)
  • aerobic interval
  • fartlek
  • circuit
110
Q

how does aerobic training affect performance

A
  • increases ability to perform for longer (bc of higher VO2 Max)
  • enables athletes to ‘surge’ within continuous activity
  • develop muscular endurance due to increased capacity to carry O2 to working muscles and increased blood volumes
111
Q

what is continuous training (aerobic training)

A

when athlete performs the same activity at the same intensity for a specified duration
E.g. running at a set speed on a flat track OR riding an exercise bike at a set intensity
best suited for sports where intensity does not change (70-85% MHR) very much and same activity is often repeated throughout competition
–> marathons, long distance rowing or swimming

112
Q

what is aerobic interval training
