Outline the ATP - PC system
Used in high intensity exercise
Anaerobic process, creatine kinase detects high level of ADP, breaks PC in muscle releasing energy which is used convert ADP to ATP,coupled reaction
Define short term lactate energy system
Produced high powered energy for high intensity effort in events such as 400m
Synthesis of 2 ATP,lasts up to 3 min but peak at 45 second
Define aerobic system
Used in low intensity exercise,glycolysis, Krebs cycle, electron transport chain
34 ATP formed
Define altitude training
Usually done at 2500+m above sea level where the partial pressure of oxygen is lower
Air drops
Reduction in the diffusion gradient of o2 between air and lungs, not much o2 diffusion so less haemoglobin saturation
Define High Intensity Interval Training (HIIT)
Period of high intensity work and recovery
Interval training used for both aerobic and anaerobic
4 main variables: duration of work interval, intensity or speed of work interval, duration of recovery interval, no of work intervals and recovery intervals
HIIT: short intervals of maximum intensity exercise follows by a recovery of low to moderate intensity exercise
Define plyometrics
Involves repeated rapid stretching and contracting of muscles to increase muscle power, high intensity explosive activities. Muscles can generate more force if they have previously been stretched.
Eccentric phase - stretching the muscle where it lengthens, under tension
Amortisation- time between the eccentric and concentric muscle contraction
Concentric - uses stored energy to increase the force of the contraction
Define SAQ
Speed, agility, quickness
Speed - how fast a person can move over a specified distance
Agility - able to move and position the body quickly and effectively
Type of training that aims to improve multi directional movement through developing neuromuscular system. Maximum force, anaerobically.
Zig zag runs
Define massed and distributed practise
Massed - no rest intervals
Distributed - rest intervals
Define varied practise
Practise that is altered and different each time and can be varied within each session e.g one practise that is massed and the next mental
Define mental practise
Going over the skill in the mind without movement
Define the 3 stages of learning
Cognitive stage of learning- no motor programmes, uncoordinated movement , slow, not fluid or controlled
Associative stage - motor programming forming, smoother movements
Autonomous stage - actions are fluent, efficient, automatic, motor programme formed
What sort of feedback is used in the stages of learning
Cognitive- extrinsic, positive, knowledge of result
Associative- start to move from external to intrinsic,
Autonomous - detailed feedback, internal, development of kinaesthetic, negative and knowledge of performance
Define learning plateau, cause and solution
A period of no improvement in performance
Cause - lack of motivation, boredom, limit of ability, fatigue
Solution, allow rest, make enjoyable, new coach
Define rational recreation
Sport pastimes for the lower class which were designed by the middle class to be well ordered, organised and controlled
What were the socio and cultural influences on the development of rational recreation in the first half
Migration to urban areas - loss of space to play traditional mob games
Lack of leisure time - shift to machine time
Lack of income - low wages and poverty evident, poor hygiene - little energy to play sport
Loss of rights - criminal law changes restricted on mob football
What were the improvements made in the second half of 19th century
Health and hygiene - public baths,enabling more energy to participate in sport
Gradual increase in wages and more time for sport due to Factory Acts
Development of new middle class
Influence Of ex public school boys
Industrial patronage - factory teams set up
Improvements in transport and communication - leagues established
What role did the Wenlock Olympian Games have
Founder: Dr William Penny Brooks, mixture of athletics and traditional sports,
Society: campaigned for physical education to be in school
What influence did urbanisation, transport, church and British Empire have on rational recreation
Lack of space - built purpose built facilities
Movement of teams/spectators - nationwide fixtures developed on regular basis
Church - encouraged social control
Middle class - took leadership in roles for NGB
officers in the British army - used sports armed service
