Muscle imbalance
Alteration of a muscle length surrounding a joint.
Obesity
The condition of being considerably overweight, referring to a person with a body mass index of 30 or
greater, or who is at least 30 pounds over the recommended weight for their height.
Overweight
A person with a body mass index of 25 to 29.9, or who is 25 to 30 pounds over the recommended
weight for their height.
Blood lipids
Cholesterol and triglycerides, carried in the bloodstream by protein molecules known as high-density
lipoproteins (HDL) and low-density lipoproteins (LDL).
Diabetes mellitus
Chronic metabolic disorder caused by insulin deficiency which impairs carbohydrate usage and
enhances usage of fats and proteins.
Deconditioned
A state of lost physical fitness which may include muscle imbalances, decreased flexibility, and a lack of core and joint stability.
Proprioception
The cumulative sensory input to the central nervous system from all mechanoreceptors that sense body position and limb movement.
Proprioceptively enriched environment
An unstable (yet controllable) physical situation in which exercises are performed that cause the body to use its internal balance and stabilization mechanisms.
Muscular endurance
A muscle’s ability to contract for an extended period of time.
Neuromuscular efficiency
The ability of the neuromuscular system to enable all muscles to efficiently work
together in all planes of motion.
Prime mover
The muscle that acts as the initial and main source of motive power
Superset
Set of two exercises that are performed back to back without any rest time between them.
Rate of force production
Ability of muscles to exert maximal force output in a minimal amount of time
Three main systems of human movement system
nervous, skeletal, muscular
Kinetic
Motion
The nervous system
A conglomeration of billions of cells specifically designed to provide a communication network within the human body.
Sensory function
The ability of the nervous
system to sense changes
in either the internal or
external environment.
Integrative function
The ability of the nervous system to analyze and interpret sensory information to allow for proper decision making, which produces the appropriate response.
Motor function
The neuromuscular
response to the sensory
information.
Neuron
The functional unit of the
nervous system.
Specialized cell that processes and transmits information
through both electrical and chemical signals.
Sensory (afferent) neurons
Respond to touch, sound, light and other stimuli and transmit nerve impulses from effector sites (such as muscles and organs) via receptors to the brain and spinal
cord.
Interneurons
Transmit nerve impulses from one neuron to another.
Motor (efferent) neurons
Transmit nerve impulses from the brain and spinal cord to effector sites such as muscles or glands.
Efferent
conducted or conducting outward or away from something (for nerves, the central nervous system; for blood vessels, the organ supplied).
