neuromuscular system Flashcards

1
Q

what is the autonomic nervous system?

A
  1. regulates the function of our internal organs eg heart
  2. controles some of our skeletal muscles within the body
  3. works involuntarily

Q

what is the neromuscular system?

A
  1. nervous system and the muscles work together to allow movement
  2. changes in the neuromuscluar system take place before, during and after exercise
  3. changes either prepare body for exercise and allow for changing demands of different intesities
  4. SNS and PNS are part of the peripheral nervous system

Q

characteristics of slow twitch muscles fibres?

A
  1. slower contraction speed
  2. better adapted to lower intesity exercise e.g long distance running
  3. produce most of their energy aerobically

Q

characteristics of fast twitch muscles fibres?

A
  1. faster contraction speed - generate a greater force of contraction
  2. fatigue quickly
  3. used for short, intense bursts of effort
  4. produce their energy anaerobically
