Fitness Glossary
- Path Variable
- Many path options.
- Pattern Overload
- Many repetitions performed in the same pattern can lead to overloading soft tissues beyond necessary stimulus.
- Pelvic Girdle
- The two hip bones.
- Pelvis
- Composed of the two hip bones, sacrum and coccyx.
- Perceived Volitional Fatigue
- Similar to Rate of Perceived Exertion (RPE). The exerciser is choosing/deciding on a specific level of exertion/fatigue based on how they feel
- Periosteum
- The fibrous connective tissue, which surrounds the surface of bones.
- Perimysium
- The connective tissue enveloping bundles of muscle fibers.
- Popliteal Space
- The space behind the knee joint. The space is bounded by ligaments and contains soft tissue including nerves, fat, membranes and blood vessels.
- Postural Response
- A change of body position that leads to a change in the projection of the center of mass.
- Planes
- The three basic planes of reference are derived from the dimensions in space and are at right angles to each other. Types of planes: Sagittal: Is vertical and extends front to back. It may also be called anterior-posterior plane. Coronal: Is vertical and extends from side to side. It is also called the frontal or lateral plane, and divides the body into anterior and posterior sections. Transverse: Is horizontal and divides the body into upper and lower portions. It is also termed the horizontal plane.
- Power
- Ability to exert muscular strength quickly.
- Prehabilitation
- Refers to the prevention of injury by training the joints and muscles that are most susceptible to injury in an activity. Unlike rehabilitation, prehabilitation deals with injuries before they occur.
- Prognosis
- Prediction of the course of an injury or disease, including its end result.
- Prone
- Lying face downward.
- Proprioception
- The neurological sense that allows one to know not only where one is in space, but also the position and location of each individual part and joint.
- Proprioceptive Neuromuscular Facilitation (PNF)
- A method of promoting a response of neuromuscular mechanisms through the stimulation of proprioceptors in an attempt to facilitate increased range of motion, increased strength and movement pattern control.
- Proximal
- Nearer to the center or median line, or to the thorax.
- Pyramiding
- Done in two ways: 1. Beginning with sets that use a lighter load and higher rep count, progressing to heavier load and lower rep count. 2. Beginning with sets that use a heavier load and lower rep count, progressing to lighter load and higher rep count.
