-
The cumulative sensory input ti the central nervous system from all mechanorecptors that sense body position and limb movement
Proprioception
-
An unstable (yet controllable) physical situation in which exercises are performed that causes the body to use its internal balance and stabilization mechanisms
Proprioceptively enriched environment
-
How quickly a muscle can generate force
Rate of force production
-
The muscle that acts as the main source of motive movement
Prime mover
-
Sets of 2 exercises that are performed back-to-back without any rest time between them
Superset
-
The ability of the body's nerves to effectively send mesages to the body's muscles
Neuromuscular efficiency
-
Primary connective tissue that connects bones together and provides stability, input to the nervous system, guidance, and the limitation of improper joint movement
Ligament
-
Connective tissues that attach muscle to bone and provide an anchor for muscles to produce force
Tendons
-
The superior chamber of the heart that recieves blood from the veins and forces it into the ventricles
Atrium
-
The inferior chamber of the heart that recieves blood from its corresponding atrium and, in turn forces blood into the arteries
Ventricle
-
High-intensity, short-duration activity (heavy weight training, sprinting)
Anaerobic Training
-
Lower intensity, longer duration activity (walking)
Aerobic
-
Moving in the same direction as the resistance
Decelerates or reduces force
Lengthening of the muscle
Eccentric
-
No visible movement with or against resistance
Dynamically stabilizes force
Isometric
-
Moving in opposite direction of force
Accelerates or produces force
Shortening of the muscle
Concentric
-
PAR-Q
Physical Activity Readiness Questionaire
-
A questionnaire that is designed to help qualify clients for activety levels and identify those who may need medical attention
PAR-Q
-
Signifies the minimum blood pressure within the arteries through a full cardiac cycle
Diastolic BP
-
Reflects the blood pressure produced by the heart as it pumps blood to the body
Systolic BP
-
Measurable data that can be utilized to denote improvements in the client, as well as the effectiveness of the program
Objective information
-
Feedback from the client to the fitness professional regarding personal history
Subjective information
-
Capability to be elongated or stretched
Extensibility
-
The type of flexibility that is designed to improve muscle imbalances and altered joint motion
Corrective flexibility
-
The type of flexibility that is designed to improve the extensibility of soft tissue and increase neuromuscular efficiency by using reciprocal inhibition
Active flexibility
-
The type of flexibility that is integrated, multiplanar soft tissue extensibility, with optimum neuromuscular control, through the full range of motion.
Movements without compensations
Functional flexibility
-
The ability to react to stimulus and change the motion of the body in all planes of motion
Quickness
-
The ability to accelerate, decelerate, and change direction quickly, while maintaining proper posture.
Agility
-
The ability to move the body in one intended direction as fast as possible
Speed
