09d. Chronic Ads - Anerobic Flashcards
Describe motor unit recruitment
A motor unit is a muscle fibre and the motor neuron which attaches to it (it passes messages from the brain to the muscle). The more motor units recruited the more force you produce.
Describe fast twitch fibres
increased size, increased force of contraction, fatigue easily
What type of muscle fibre has increased size, increased force of contraction and fatigues easily
Fast twitch fibres
Which energy system is associated with having a high LA tolerance
anaerobic glycolysis
What does hypertrophy mean?
increase muscle size
What is CP?
the fuel of the ATP-CP system
What is an advantage of using glycogen as a fuel?
increased rate of ATP resynthesis
What is an disadvantage of using glycogen as a fuel?
limited stores, decreased yield
Whats is a motor unit is a muscle fibre and the motor neuron which attaches to it (it passes messages from the brain to the muscle).
motor unit recruitment
List 7 Anaerobic Chronic adaptations
Increased muscle size, speed of motor unit recruitment, ATP, CP and glycogen stores, ATPase and glycolytic enzymes
Outline how increased muscle size directly impacts performance
Increased force of contraction so can jump higher / sprint faster etc
Outline how increased speed of muscle contraction directly impacts performance
Faster reaction time
Outline how increased ATP, CP, Glycogen stores and ATPase directly impacts performance
Increased ability to use fuels for anaerobic energy production = increased speed/ability to use anaerobic energy systems
Outline how increased LA tolerance directly impacts performance
Able to work at maximal intensity for longer
