HPE Exam 1 #1 Question with verified answers
skeletal muscle 3 main function - √√1.movmemt
2.posture and balance
3.regulate core body temp
make up of skeletal muscles - √√-muscle fibers
-tendons connects the muscle to the bone
-three main fiber types
three main fiber types - √√type 1, type 2b, type 2a
type 1 - √√: do not generate a lot of force, they contract slowly. They are however
fatigue resistant;
Highly aerobic->Always recruited by motor units first in every activity
type 2b - √√They generate a lot of force, and are very strong.
They fatigue quickly.
They are anaerobic type
->Recruited last
type 2a - √√Best of both worlds.
Known as "super fibers" because they can doa little of both worlds.
->Recruited next
o Can only contract, or relax
, motor unit - √√Motor neuron and the muscle fibers it is attached to.
• Types of Muscle Contraction - √√1.concentric
2. isometric
3.eccentric
concentric - √√Lifting up the dumb bell in a curl
isometric - √√holding the contraction
eccentric - √√relaxing the muscle back to resting position
• Two types of Static Strength Training - √√1) Isometric Excercises
2) Dynamic Strength Training
1) Isometric Excercises - √√-> Generating force in contraction, but no lengthening
of muscle
(planks, lower back strengthening)
Prone to Valsalva Maneuver. Better to exhale and breath out as you lift weights
2) Dynamic Strength Training - √√b) Isotonic
a) Isokinetic
