and 4 questions and answers
What type of joint is the knee? ✔✔hinge joint
What is the joint action of the knee and what plane of movement does this joint action occur?
✔✔flexion/extension; coronal (frontal)
List the four muscles groups that are associated with the knee and the joint actions for which
each is responsible. ✔✔quadriceps extend the knee joint, hamstrings flex the knee joint,
adductors adduct (pull in) the knees, abductors abduct (push out) the knees
How will students benefits from participating in a fitness program that provides exercises
designed to improve posture? ✔✔restore good posture, develop muscles equally, optimum
flexibility, increase range of motion, realign the spine
What percentage of Americans suffers from back pain at some point in their lifetime? ✔✔80%
How can poor posture negatively impact the internal organs? ✔✔it can affect how they function
and breathing patterns
List and describe the four posture types ✔✔a) anatomically ideal: balanced relationship of all
the skeletal muscles, bones of spine are stacked, weight is supported by legs and pelvis
b) flat back: posterior tilt of the pelvis, eliminated thoracic curve, retracted chin
c) lordotic/kyphotic: lordotic - strong anterior tilt, head forward, exaggerated curve of lower
back; kyphotic - stretches extensors, collapses upper chest, neutral pelvis
