Week 10 - training for performance Flashcards
How does genetics effect anaerobic capacity differently to aerobic capacity
Anaerobic capacity is more genetically determined than aerobic
Training can improve anaerobic performance to a small degree
Dependent largely on fast 2x fibers
What are the 3 key elements that contribute to aerobic performance
High vo2 max
Superior exercise economy/efficiency
High lactate threshold and critical power
Whats the effect of low responders (genotype A) on vo2 max
Posses a relatively low untrained vo2 max
Often exhibit limited exercise response as vo2 max improves by 5% or less
Whats the effect of high responders (genotype E) on vo2 max
Individuals with the ideal genetic makeup required for champion endurance athletes
Possess a relatively high untrained VO2 max
Often increase vo2 max by 50% with training
Whats the influence of sex and inital fitness levels
Males and females respond similarly to training programs.
training improvement is always greater in individuals with lower initial fitness
How are training improvements greater in individuals with lower initial ftiness
50% increase in vo2 max in sedentary adults
10 to 20% imporvement in normal active subjects
3 to 5% improvement in trained athltes
How does absolute strenght differ between untrained males and females
Upper body 50% stronger
Lower body 30% stronger
How is strength/cross sectional area of muscle differnet between males and females
It is similar between both
3 to 4 kg of force per cm2 of muscle in both
How does responses to short-term training differ between males and females
There are no sex differences in response to short-term strenght training
However, men exhibit greater hypertrophy as a result of long-term training due to higher testosterone levels
What are the 3 primary training methods to improve aerobic power and what are they designed to improve
Interval training, long slow distance, high intensity, continuous exercise
Training is designedd to improve vo2 max, lactate threshold, running economy
How are injuries and endurance training related
SHort term, high intensity exercise
Prolonged injury, low intensity exercise
10% rule - increase intensity or duration <10% per week
What are some other injury risk factors
Strength and flexibility imbalance
Footwear problems
Malalignment
Poor running surface
Diseases (arthrititis)
How does the ATP-PC system suit improving anaerobic power
Short (5 to 10 seconds) high intensity work intervals
30 metre sprints for football players
30 to 60 second rest intervals, little lactic acid is produced so recovery is rapid
How does the glyolytic system suit improving anaerobic power
Short (20 to 60 seconds) high intensity work intervals
May deplete muscle glycogen levels
May alternate hard and light training
