Pe Revision Flashcards
Athletes diet:
BMI (4 marks)
Weight(kg) / height (m2)
27+ BMI means increased risk of health problems
Doesn’t account for muscle weighing more than fat
Trained athlete could have same BMI as untrained
Athletes diet:
Bioelectrical impedance (4 marks)
Sends weak electrical impulse through the body
Hand held device
Travels quickly through the muscle and slowly through fat
Calculates body fat % through the strength of the impulse
Athletes diet:
Skinfold Calipers (2 marks)
Measures subcutaneous fat
Various sites on the body to calculate body fat
Periodisation:
Definition
Training is organised into blocks of time (cycles) to prepare physically and psychologically for competition
Periodisation:
Preparation phase (4 marks)
Develop baseline fitness
General conditioning: endurance, strength, mobility
Quantity not quality
Competition focus - tactics and techniques to increase speed and intensity
Periodisation:
Competition phase (4 marks)
Refine skills in a competitive enviroment
Maintain fitness
Quality not quantity
Tapering - drop in intensity to prepare psychologically and physically for competition
Periodisation:
Transition phase (3 marks)
Between the end of one season and the start of another
Active rest
Maintain fitness
Periodisation:
Cycles - macro (3 marks)
Long term development plan
1 year for football
4 years for Olympic athletes
Periodisation:
Cycles - meso (2 marks)
Long term plan divided into smaller blocks
2-8 weeks long
E.g focus on speed
Periodisation:
Cycles - micro (2 marks)
One session a week
Increased detail on intensity and duration and volume and content
Periodisation:
Single periodisation (3 marks)
One peak
long term development
Increased intensity and duration of training
Periodisation:
Double periodisation
2 peaks
Periodisation:
Multiple periodisation (3 marks)
Many peaks
Increased frequent high intensity phases in training
To maintain intensity for elite athletes
Confidence and self efficacy:
Self efficacy (2 marks)
Situation specific confidence
Belief in own ability to succeed in a specific situation
Confidence and self efficacy:
Social facilitation (2 marks)
The influence of the presence of others affects performance
The presence of others increases arousal
Confidence and self efficacy:
Influence of self efficacy on performance (5 marks)
Increase motivation Positive attitude Decrease anxiety and stress More likely to reach optimum performance Decrease NAF, increase Nach
Confidence and self efficacy:
Social inhibition
The negative effect of others on performance
Confidence and self efficacy:
Self confidence (2 marks)
Belief in your own ability to succeed
Aspect of self esteem
Athletes diet:
Main Points (6 marks)
Carbohydrates to meet energy demands
Hydrated via drinking
Balanced diet
Avoiding processed foods
Fats for low/medium intensity, exercise and glycosparing
Fats for insulation and protection of vital organs
Glycoloading:
Supercompensation
Intake more glycogen than normal in order to delay fatigue
Glycoloading:
Dietary Manipulation
One week before competition, reduce carbohydrate intake to decrease glycogen stores
Take part in either high intensity training/ endurance to reduce stores of glycogen further
A few days before, increase glycogen intake and drink lots of water to aid digestion
Glycoloading:
Carbohydrate window
The day before the event high intensity exercise for 3 minutes
This opens the carbohydrate window
Eat lots of glycogen for the next 20 minutes
Consume more water to aid the process of digestion
Glycoloading:
Advantages
Delays fatigue
Increase glycogen source
Greater aerobic energy sources
Easy to manipulate your diet
Glycoloading:
Disadvantages
Heavy legs due to water retention
Tapering decreases fitness
Negatively effects metabolism
Plyometrics:
Knowledge
Aim - develop muscle elasticity, power and strength
Depth jump done by athletes of power
Stretch shortening cycle:
- pre stretch reflex
- amoitisation
- muscle contractions
Plyometrics:
Benefits
Hyper trophy of muscle fibres
Increase muscle elasticity
Recruitment of more fast twitch fibres to motor units
Better coordination between fast twitch motor fibres
Plyometrics:
Advantages
Increase maximum muscle power
Increase muscle strength elasticity
Can be made sport specific
Plyometrics:
Disadvantages
Can cause chronic injuries e.g shin splints/Achilles tendons
Rupture tendons and ligaments
Damage vulnerable ankle and knee joints
