The metabolic process that creates energy from the splitting of glucose to form pyruvic acid or lactid acid and ATP
Glycolysis
System designed to cause action; consists of somatic and autonomic systems
Efferent System
The part of the PNS that sends messages to the CNS
Afferent System
Responsible for voluntary action : skeletal muscles
Somatic System
Processes and activates involuntary action: blood vessels, glands, internal organs
Autonomic System
Consists of the glands and tissues that release hormones. Works with nervous system in regulating metabolic activities.
Endocrine System
- Alter the rate of protein synthesis 2. Change the rate of enzyme activity 3. Change the rate of transport of nutrients through the cell wall. Classifications: Amino Acid Derivatives, Peptides/Protein, and Steroids
Hormones
A byproduct of glycolsis. Gateway to the final common energy producing pathway, the krebs cycle, and it provides acetyl coenzyme A through which fatty acids, and in turn fat, are produced from glucose. Also converts to lactic acid as needed.
Pyruvate Acid
Body system that consists of the bones, joints, connective tissue and muscle.
Musculoskeletal System

Neutralizer
Continuous muscle contraction to keep the weight moving
Sustained Movement
Inertial movement after an explosive or quick, maximum force contraction.
Ballistic Movement
Both the agonist and antagonist contract to control the movement.
Guided Movement
Movements in which there are constant agonist, antagonist muscle contractions to maintain a certain position or posture.
Dynamic Balance
The study of the mechanical aspects of physical movement, such as torque, drag, and posture, that is used to enhance athletic technique.
Biomechanics
Magnitude : How much force is applied Direction: The way which the force is applied Point of Application: Where the force is being applied on the body Line of Action: A straight line is drawn from the point of application of force through the direction of force.
4 Components of force
(Twist) Rotary movement in any plane around an axis
Torque
The ability to perceive your position and movement of the body or limbs in space.
Kinesthesis
Tight: Lower back (erectors), hip flexors Weak: Abdominals (especially obliques), hip extensors
Lordosis
Tight: Upper-Abdominals, hip extensors Weak: Lower back (erectors), hip flexors
Flat Back
Tight: Upper Abdominals, hip flexors Weak: Obliques, hip extensors
Swayback
Tight: Internal oblique, shoulder adductors (pectorals, lattisimus), intedcostals Weak: Erector spinae of the thoracic spine, scapular adductors (mid and lower trapezius)
Kyphosis
Tibia and talus bones.
The ankle joint is made up of which bones?
The most important functional unit of the body. It provides the main framework and foundation for most of the movements of the body and extremities.
Explain the role of the spine in the body.
They work together to creat max ROM in your ability to raise the legs as high as possible.
Whats the relationship between the abdominal muscles and hip flexors.
Anterior: biceps, brachialis, pronator teres, Postetior: triceps, anconeus
The elbow joint is comprised of which muscles?
A combination of three joints located at the wrist, elbow, and inbetween the ulna and radius bones.
The radioulnar joint is made up of which bones.
These muscles act as stabilizers and produce either pronation or supination. Includes: Biceps Supinator Pronator Teres Pronator Quadratus
The radioulnar joint is made up of which muscles?
The ends of the radius and ulna bones of the forearm and the carpal bones of the hand.
The wrist joint is made up of which bones?
Flexor carpi radialis Flexor carpi ulnaris Palmaris longus
The wrist joint is comprised of which muscles?
The strength exhibited at different points in the range of motion will vary because of the angle at which the muscle pulls.
Angle of Pull
Our ability to contract our muscles with max force given constaints stemming from structural / anatomical factors, physiological / biomechanical factors, psychoneural / psychosocial factors, and external / environmental factors.
Strength
The amount of musculoskelatal force you can generate for one all out effort. "Athletic Foundation"
Limit Strength
Inhaling and holding breath on exertion provides up to 20% greater force. Stabilizes the spine and helps prevent lower back injuries.
Valsalva Maneuver
Range of training intensity that will produce improvement in your level of aerobic fitness.
Aerobic Training Zone
Unit of measurement that refers to the relative energy demands of an a activity in comparison to your energy demands in a resting state.

While we all have similar responses and adaptations to the stimulus of exercise, the rate and magnitude of these changes will be limited by our differing genetics.
The Principal of Individual Differences
Our bodies will compensate to handle any repeated stress that our system faces.
Overcompensation Principal
In order for gains to continue, the intensity of the stress imposed must be progressively increased.
Overload Principal
Specific Adaptation to Imposed Demands States that our bodies will physiologically adapt according to whether we are training aerobically or anaerobically.
SAID Principal
States that our bodies will adapt to current exercise or lack there of. Use it or lose it.
Use / Disuse Principal
States that we must move from general training to specific and highly specialized training as it relates to our intended goals.
Specificity Principal
