Anatomy
This sesamoid bone is embedded within the quadriceps tendon.
Patella
This is the term referring to a decrease in muscle size and strength
Atrophy
This type of blood vessel brings blood back to the heart.
Vein
The point where rotation occurs in a lever system
the axis (or fulcrum)
This is defined as any bodily movement produced by the contraction of skeletal muscles that results in an increase in caloric requirements over resting energy expenditure.
Physical Activity
This muscle is the primary agonist during neck flexion
Sternocleidomastoid
This is the functional unit of skeletal muscle
Sarcomere
The right ventricle ejects blood into this major blood vessel.
pulmonary trunk
Power is defined as work divided by this variable.
time
ACSM recommends at least this many minutes per week of moderate-intensity aerobic exercise
150 minutes per week
This is the longest muscle in the human body
Sartorius
This relationship describes how muscle force changes depending on muscle length
length–tension relationship
This cardiovascular measurement represents the proportion of end-diastolic volume ejected during systole.
Ejection Fraction
The stretch-shortening cycle enhances performance primarily through storage and release of this type of energy.
elastic energy
Neuromotor exercise is especially emphasized for this population
older adults
This joint type allows movement in all three planes, such as the shoulder
ball-and-socket joint
Calcium binds to this protein to initiate muscle contraction
troponin
This vasodilator is released by the endothelium and helps blood vessels relax during exercise.
Nitric Oxide
The gastrocnemius during a heel raise functions as part of this class of lever
second-class lever
The range of MET values associated with moderate intensity
3.0 - 5.9
These are the three structural properties of the lungs that maximize diffusion according to Fick’s Law
large surface area, thin membrane, slow moving blood
This structural protein helps maintain alignment of thick filaments and contributes to passive tension
titin
This is a cardiac property where an increase in ventricular filling stretches the cardiac muscle fibers, resulting in a more forceful contraction and increased stroke volume.
Frank-Starling mechanism
A diver tucks during a somersault to decrease this variable
moment of inertia
This population is at a higher risk of adverse events in cold and dry environments
Asthmatics
