Bioenergetics

Study of energy in the human body

Metabolism

Process in which nutrients are required, transported, used, and disposed of by the body

Aerobic

Requires oxygen

Anaerobic

Without oxygen

Adenosine triphosphate ATP

Energy storage and transfer unit within cells

Anaerobic threshold

Where the body can no longer produce enough energy with normal oxygen intake

Excess post oxygen consumption EPOC

Elevation of metabolism after exercise

Biomechanics

Science concerned with internal and external forces acting on the body

Force

Influence applied by one object to another, accelerates or decelerates the second object

Torque

A force that produces rotation

Lever

Rigid “bar“ that rotates around a stationary fulcrum

First class lever

Fulcrum in the middle nodding head

Second class lever

Resistance in the middle. Caffrey’s

Third class

Effort in the middle. Bicep curl; most common in human limbs

Superior

Above a point of reference

Inferior

Below a point of reference

Proximal

Nearest to a point of reference

Distal

Farthest from a point of reference

Anterior

Front of the body

Posterior

Back of the body

Medial

Closer to the middle of the body

Lateral

Farther from the middle of the body

Contralateral

On the opposite side of the body

Ipsilateral

On the same side of the body

Frontal

Adduction/abduction, lateral flexion, eversion/inversion

Sagittal plane of motion

Flexion/extension

Transverse plane of motion

Rotation, horizontal adduction/abduction

Flexion

Bending movement; decreases relative angle between segments

Extension

Straightening movement; increases relative angle between segments

Plantarflexion

Extension at the ankle

Dorsiflexion

Flexion at the ankle

Abduction

Movement in the frontal plane away from the middle

Abduction

Movement in the frontal plane toward the metal

Horizontal abduction

Transverse plane are movement from anterior to lateral i.e. chest fly

Horizontal adduction

Transverse plane our movement from lateral to anterior

Internal rotation

Rotation toward the middle of the body

External rotation

Rotation away from the middle of the body
