  • Peripheral cardiovascular responses

    Responses directly related to the vessels.  

  • Peripheral cardiovascular adaptations

    Adaptations that occur in the vasculature or muscles that increase the ability to extract oxygen. The process of engulfing and digesting an antigen.  

  • Periodization

    Plan for training based on a manipulation of the fitness components with the intent of peaking the athlete for the competitive season or varying health-related fitness training in cycles of harder or easier training.  

  • Perfusion of the lung

    Pulmonary circulation, especially capillary blood flow.  

  • Percent saturation of hemoglobin (SbO2%)

    The ratio of the amount of hemoglobin combined with oxygen to the total hemoglobin capacity for combining with oxygen, expressed as a percentage; indicated generally as SbO2% or specifically as SaO2% for arterial blood or as SvO2% for venous blood.  

  • Peak power (PP)

    The maximum power (force times distance divided by time) exerted during very short-duration (5 sec or less) work.  

  • Partial pressure of a gas (PG)

    The pressure exerted by an individual gas in a mixture; determined by multiplying the fraction of the gas by the total barometric pressure.    

  • Pulse pressure

    The difference between systolic and diastolic pressure (subtract the diastolic pressure from the systolic pressure). The difference between the diastolic and systolic pressure. Difference between the systolic and diastolic blood pressure readings, which is normally ranges between 30 and 50 mm Hg. The difference between systolic and diastolic pressures. The systolic pressure is normally about…

  • Pulmonary ventilation

    Movement of air in and out of the lungs. The process by which air is moved into and out of the lungs. The inspiration and expiration of air from the lungs.  

  • Pulmonary diffusion

    Rate of exchange of carbon dioxide and oxygen moving in the lungs.
