Q

example of isomeric contraction

A

a 3 year old tries to lift the ball but cant; when can’t move anymore weights; myofilaments try to slide but cant

Q

what is the purpose of aerobic/endurance training

A

get more red fibers, greater blood supply to muscles= more O2 and # of mitochondria, increased metabolism, improved digestion and skeletal strength

Q

what is the purpose of resistance training

A

get more white fibers, isometric exercise that increase muscle size (increases diameter of individual muscle cells)

Q

describe pennate arrangement of fascicles

A

short, oblique attachements to central tendon; most powerful becuase most fibers dont shorten much
