43
Progressive overload
Gradually increasing the load that your body is working against. Alter the intensity and volume of sessions and the frequency of training.
44
Specificity
Implies a close relationship between training activities and those used in an event.
Muscles - appropriate muscle groups being trained.
Movement - movement patterns being used Mirror those performed in competition.
Metabolic - energy systems are being trained in the proportions to which they are used in performance.
45
Reversibility
The effects of training can reverse as a result of de training.
46
Variety
Used to avoid boredom, associated with repetitious, eg training for endurance events.
Promotes enthusiasm and motivation. Eg stationary training for cyclists
47
Training thresholds
Points that indicate the zone for athletic improvement to occur.
Aerobic threshold - 60-80% maximum HR. Gives max fat burning and health benefits from cardioVascular activity.
Anaerobic threshold - OBLA occurs, results in fatigue and trains in aerobic system again. Training causing increase tolerance to lactic acid
48
Warm up and cool down
Reduce risk of injury
Prepares athlete mentally
Increase body temp and enzyme activity to promote faster muscle contractions.
Stimulate respiratory and cardiovascular system to increase blood flow to muscles.
Brings HR back to normal
Prevents muscle soreness
49

```
Heart rate
Stroke volume
Cardiac output
Haemoglobin levels
Lung capacity
Oxygen uptake
Hypertrophy
Effect of fast/slow twitch muscle fibres
```

| Trained athlete has lower heart rate
51
Stroke volume and cardiac output
Amount of blood ejected from the heart per beat.
Increase in stroke volume due to endurance training.
Amount of blood ejected from the heart per minutes. Q=HR x SV
52
Haemoglobin levels
Haemoglobin - transports oxygen around the body to working muscles and body parts that require oxygen.
Found in red blood cells.
Increases with training and increase further when training at high altitudes.
53
Oxygen up take and lung capacity.
Amount of oxygen the body uses per minutes, the maximum capacity of an individual's body to transport and utilise oxygen. Improves as a result of training.
Amount of air that the lungs can hold with one breathe.
54
Muscle hypertrophy
Increase in size of the muscle.
55
Effect on fast/slow twitch muscle fibres
Fast twitch - explosive movements, sprints, white fibres.
Slow twitch - longer, slower contractions, endurance, red fibres.
Adaptations that occur (slow) - hypertrophy, capillary supply, mitochondria function, myoglobin content
Fast twitch muscle fibres need to be trained other reversibility occurs.
Adaptations (fast) - hypertrophy, ATP/PC supplies, lactic acid supplies
56
What is motivation
Internal state or condition that activates behaviour and gives it direction, desire or wants that energise and directs goal orientated behaviour.
57
Positive and negative
Positive - includes praise, rewards and recognition for good performance.
Negative - involves completing tasks out of fear because the athlete is aware that there will be undesirable consequences. Eg, being replaced due to making too many errors.
58
Intrinsic and extrinsic
Intrinsic - motivation from within which is a result of interest/enjoyment. Main motivation for young people
Extrinsic - desire to perform is in anticipation of an external reward (money).

Recovery strategies
Physiological
Neural
Tissue damage strategies
Psychological strategies
71
Physiological recovery strategy
Cool down (active recovery) - easiest and simplest form of recovery. Restores muscle to previous state, disposed of lactic acid, cost effective.
Hydration - drink fluids post performance to replenish lost fluid. Gets body back to original state, reduces effects of dehydration.
72
Neural recovery strategies
Hydrotherapy - steam room, spas. Water provided buoyancy, allows for support to complete easy exercise with minimum impact on the body. Assists with maintaining fitness after injury, decreases muscle soreness.
Massage - manipulation of the muscles, reduces the lactic acid levels in body, aids recovery of soft tissue injuries.
73
Tissue damage recovery strategies
Cryotherapy - use of colliding as a mean of treating injuries. Vasoconstriction in blood vessels due to cold decrease amount of blood and scar tissue build up.
74
Psychological recovery strategies
Flotation tanks, soothing music, sleep, meditation - decrease heart rate, arousal level and blood pressure, relax muscles, allows injury to heal.
75

76
Vitamins
B vitamins produce energy from the fuel sources in the diet.
77
Caffeine
Cognitive function, increase concentration and alertness. Performance enhancement, assists with metabolism. Found in coffee, tea and cola. Excess may cause dehydration.
78
Protein
Growth and repair maintenance of body tissue. Found in fish, chicken, cheese, cereals, protein bars, red meat. Excess can cause kidney failure
79
Creatine
