What does PIE mean in PHYSIOLOGY

PIE stands for Pressure Ice And Elevation.

All three elements — pressure, ice, and elevation — play a role in determining the quality of an ice skating surface. The air pressure affects air temperature inside the rink, which impacts surface friction; the type of ice affects durability; and elevation has a direct effect on how quickly water will evaporate off the surface. All three factors must be taken into consideration when building and maintaining an ideal environment for skating.

Air pressure impacts air temperature inside the rink, which directly influences surface friction and how quickly water will evaporate off the surface. If a rink has too little or too much air pressure, it can cause problems such as slippery surfaces that are prone to melting and freezing rapidly.

The higher a rink is above sea level, the less dense its atmosphere will be compared to rinks located at lower elevations. This means that it takes longer for water to evaporate from higher-elevation rinks than those located at lower elevations as there is less atmospheric pressure present to push moisture away from where it needs to dry out.

Different types of ice have varying levels of durability and strength depending on what materials they're made with (e.g., artificial or natural snow). Artificial snow tends to be more durable while natural snow tends to melt faster due its high porosity; thus these two varieties provide slightly different experiences during skating sessions as well as require different maintenance routines (e.g., scraping or resurfacing).
