Kinanthropometry
The study of the body's physical measurements as they
relate to motion.
Kinematics
The branch of biomechanics or dynamics concerned with
describing the motion of bodies, ignoring the forces
producing the motion.
Kinesiology
The study of the principles of mechanics and anatomy in
relation to human movement. The empahasis is on how the
structure affects the motion and stability of the human
body.
Kinesthesis
Sense of movement and position of the body and limbs made
possible by receptors, such as semicircular canals
utricle and saccule hair cells, Golgi tendon organs,
muscle spindles, joint receptors, skin receptors
(cutaneous and subcutaneous).
Kinesthetic
Perception
The level of awareness of the sense of movement and
position of the body and limbs.
Kinetic
Energy (KE)
An object doing work as it moves linearly or by rotation.
Linear KE = 1/2mv2, where m = mass and v =
velocity. Rotational KE = Iw2, where I = the
moment of inertia of the object about an axis that is
placed in the center of gravity of the rotating section;
and w = the angular velocity of the rotating
section.
Kinetic
Link Principle
Consideration of the segments of the body with regard to
coordination, sequencing and timing to increase the
distal segment velocity for work or athletic
performance.
Kinetics
An area of physics (specifically mechanics) that studies
the forces that act on a system.
Krebs
Cycle
Also known as the Tricarboxylic Acid Cycle or Citric Acid
Cycle, the Krebs Cycle is one of three components of
aerobic metabolism (The other two components are Electron
Transport and Oxidative Phoshporylation). In the Krebs
Cycle pyruvate is joined with a vitamin B derivative
Coenzyme A (A is for acetic acid), which forms
Acetyl-CoA, which is the entry substrate for the Krebs
Cycle. The Krebs Cycle occurs in mitochondria where
carbon compounds are oxidized, carbon dioxide is produced
and hydrogen ions and electrons are removed from
substrates. The importance of the Krebs Cycle is the
generation of hydrogens and electrons. Oxygen is not
directly involved with the Krebs Cycle. Oxygen is
involved with the Electron Transport System where it is
the final electron acceptor. If oxygen is not available,
NAD+ (nicotinamide adenine dinucliotide) and FAD (flavin
adenine dinucleotide) are not available to pick up more
hydrogens and keep the Krebs Cycle going.
KSA
Knowledge, Skills and Abilities categorized by the
American College of Sports Medicine for standards of
different certification categories.
Kyphosis
Excessive forward curvature of the vertebral column in
the thoracic region.
