Abs - ANSWER-Rectus Abdominis (lumbar spine flexion)
External Obliques (largest muscle of ab)
Internal Obliques
Transversus Abdominis (stabilizes trunk)
Pelvis Structure - ANSWER-Ilium: the largest and uppermost
pelvic bone. Wing of ilium is called the iliac crest.
Ischium: strongest of the hip bones
Pubis: where the left and the right hip bone join.
Saccrum:
Connective tissue - ANSWER--Protect and insulate
internal organs -Bind together and support other
tissues in the body -Divide structures like skeletal
muscle.
Multifidus - ANSWER-muscles that allow for extension
,Shoulder ROM - ANSWER-Horizontal Abduction: post up
Horizontal Adduction: arm hugs
3 Types of Muscle Failure - ANSWER-1) Myofibril Failure (WF):
resistance so great that the contractile components fail.
2) Intermediate Failure (RF)
3. Mitochondrial Failure (RS)
Motor Unit Recruitment - ANSWER-1) Immediate Recruitment
(WF):
immediately applying heavy resistance triggers more motor
units. Muscle feels hard.
2)Contractile Speed Recruitment (RF): performing
compensatory movements, "ballistics", power training,
plyometrics.
3) Depleting Energy Recruitment (RS): each repetition steadily
depletes the working motor unit of energy. By the time the
white fast starts working, the muscle is tired and lactic acid
builds up. Also, lack of energy production caused by waste
build up.
Motor Unit - ANSWER-Entire structure, consisting of motor
neurons and muscle fibers. Motor units are triggered to
contract through nerve "innervation." Myofibrils - ANSWER-
, White Fast- have a greater amount of myofibrils which restricts
its contraction duration.
Red Slow: Can contract for long periods of time without
fatiguing.
Capillaries and Energy - ANSWER-oxygen rich blood is
delivered to the muscle cell by a tube called the "capillary"
(pills deliver healing). Red slow doesn't have much myosin-
ATPase and generate less tension. WF fibers have less calories
therefore they must rely on glycolysis (the breakdown of
glucose).
Glycolysis - ANSWER-A pathway of aerobic metabolism in
which glucose is oxidized to pyruvic acid for the production of
ATP.
Glucose-->pyruvic acid-->ATP
White Fast Muscle Fibers are also called.... - ANSWER-fast-
glycolytic fibers
Red fast fibers are use both... - ANSWER-oxidative (aerobic) or
glycolytic (anaerobic) metabolic pathways. They are sometimes
called "fast oxidative fibers".
