Osteopenia
A disorder in which bone density is below average, classified as 1.5 to 2.5 standard deviations below peak bone density.
Osteoporosis
A disorder, primarily affecting postmenopausal women, in which bone mineral density decreases and susceptibility to fractures increases.
Outcome goal
A goal that can be assessed via a measured outcome [e.g., weight loss of 5 pounds (2.3 kg)].
Overfat
The presence of excess body fat that can impair health, even for normal weight non-obese individuals.
Overload
The principle that a physiological system subjected to above-normal stress will respond by increasing in strength or function accordingly.
Overtraining syndrome
The result of constant intense training that does not provide adequate time for recovery; symptoms include increased resting heart rate, impaired physical performance, reduced enthusiasm and desire for training, increased incidence of injuries and illness, altered appetite, disturbed sleep patterns, and irritability.
Overuse condition
Refers to a state of repetitive movements and faulty body mechanics leading to excessive forces being applied beyond what tissues can normally withstand and. over time, may lead to overuse 1nJunes.
Overuse injury
An injury caused by activity that places too much stress on one area of the body over an extended period.
Overweight
A term to describe an excessive amount of weight for a given height, using height-to-weight ratios.
Oxidation
Process of oxidizing, or the addition of oxygen to a compound with a resulting loss of electrons.
Oxygen uptake (V02 )
The process by which oxygen is used to produce energy for cellular work.
Pacinian corpuscle
A specialized bulblike mechanoreceptor located in the subcutaneous tissue of the skin responsible for detecting pressure; occur abundantly in the skin of palms, soles, and joints.
Palpation
The use of hands and/or fingers to detect anatomical structures or an arterial pulse (e.g., carotid pulse).
Palpitation
A rapid and irregular heartbeat.
Parasympathetic nervous system
A subdivision of the autonomic nervous system that is involved in regulating the routine functions of the body, such as heartbeat, digestion, and sleeping. Opposes the physiological effects of the sympathetic nervous system (e.g., stirnulates digestive secretions, slows the heart, constricts the pupils. and dilates blood vessels).
Paroxysmal nocturnal dyspnea
Attacks of severe shortness of breath and coughing that generally occur at night.
Partial pressure
The pressure of each gas in a multiple gas system, such as air, which is composed of nitrogen, oxygen, and CO2
Partnership
A business entity in which two or more people agree to operate a business and share profits and losses.
Passive recovery
Complete rest; no activity at all.
Patellofemoral pain syndrome (PFPS)
A degenerative condition of the posterior surface of the patella, which may result from acute injury to the patella or from chronic friction between the patella and the groove in the femur through which it passes during motion of the knee.
Peptide YY
A satiety hormone that is released from the intestines.
Perceived seriousness
An individual’s feelings regarding the severity associated with developing an illness or disease. This is one of the four constructs of the health belief model.
Perceived susceptibility
An individual’s perception of the risk of personal vulnerability to illness or disease. This is one of the four constructs of the health belief model.
Percent daily value (POV)
A replacement for the percent Recommended Dietary Allowance (RDA) on the newer food labels. Gives information on whether a food item has a significant amount of a particular nutrient based on a 2,000-calorie diet.
Performance goal
A goal that represents change in a measurable variable, such as increases in strength scores, reductions in resting heart rate, or weight loss.
Perfusion
The passage of fluid through a tissue, such as the transport of blood through vessels from the heart to internal organs and other tissues.
Perimysium
A sheath of connective tissue that covers a bundle of muscle fibers.
Periodization
The systematic application of overload through the pre-planned variation of program components to optimize gains in strength (or any specific component of fitness), while preventing overuse, staleness, overtraining, and plateaus.
Periosteum
A double-layered connective tissue sheath surrounding the outer surface THE EXERCISE PROFESSIONAL’S GUIDE TO PERSONAL TRAINING of the diaphysis of a long bone; serves to cover and nourish the bone.
Periostitis
Inflammation of the membrane of connective tissue that closely surrounds a bone.
Peripheral arterial disease (PAD)
Any disease caused by the obstruction of large peripheral arteries, which can result from atherosclerosis, inflammatory processes leading to stenosis, an embolism, or thrombus formation.
Peripheral nervous system (PNS)
The parts of the nervous system that are outside the brain and spinal cord (central nervous system).
Peripheral resistance
The resistance of the arteries to blood flow. As the arteries constrict, the resistance increases; as they dilate, resistance decreases.
Peripheral vascular disease
A painful and often debilitating condition, characterized by muscular pain caused by ischemia to the working muscles. The ischemic pain is usually due to atherosclerotic blockages or arterial spasms, referred to as claudication. Also called peripheral vascular occlusive disease (PVOD).
Peripheral vasoconstriction
The narrowing of blood vessels resulting from contraction of the muscular wall of the vessels, particularly in the periphery of the body (limbs).
Peripheral vasodilation
The widening of the blood vessels (vasodilation) of the peripheral vasculature in the systemic circulation.
Person-centered care
Healthcare services that are tailored to individuals’ needs and provided in partnership with them.
Pes cavus
High arches of the feet.
Pes planus
Flat feet.
Pharynx
The muscular membranous tube extending from the base of the skull to the esophagus.
