Maximum Heart Rate MHR: The fastest and hardest a person's heart can pump without going into fibrillation. This rate obviously differs according to age and body type although an basic estimation can be found by subtracting your age in years from 220.
Maximum Oxygen Uptake or VO2 Max: An indication of cardiovascular efficiency. The maximum amount of oxygen can use per minute of work. If, the intensity of exercise increases further the body starts to work anaerobically and lactic acid is produced—although most people get soreness from lactic acid before he or she reaches VO2 Max.
Metabolism: The sum of the processes by which a particular substance is handled (the breaking down, assimilation and incorporation) in the body. People with a higher metabolism, have systems which digest, assimilate, detoxify and subsequently excrete food and nutrients more quickly.
Metabolite: A produce or single step/phase in a chain of metabolites which make a metabolism process.
