ATP (Adenosine Triphosphate)
The primary biochemical energy carrier in human cells, produced via aerobic and anaerobic breakdown of glucose and fatty acids.
HRV (Heart Rate Variability)
The variation in milliseconds between consecutive heartbeats. Higher baseline HRV reflects dominant parasympathetic recovery tone.
RMR (Resting Metabolic Rate)
The minimal calories your body expends at rest over 24 hours to keep vital organs functioning.
Progressive Overload
The gradual increase of physiological stress placed upon musculoskeletal structures during exercise to stimulate adaptation.
Circadian Rhythm
An internal ~24-hour biological cycle synchronized by the suprachiasmatic nucleus (SCN) in response to environmental light.
NEAT (Non-Exercise Activity Thermogenesis)
Energy expended for everything we do that is not sleeping, eating, or formal sports exercise (e.g. walking, typing, fidgeting).
DOMS (Delayed Onset Muscle Soreness)
Muscular tenderness appearing 24 to 72 hours after novel unaccustomed eccentric muscle loading, caused by micro-trauma repair.
Prebiotic Fiber
Indigestible plant carbohydrates that selectively nourish beneficial probiotic bacteria in the colon, producing short-chain fatty acids.
The Four Pillars of 24-Hour Energy Expenditure (TDEE)
Commercial apps often convince people that formal cardio is the primary driver of calorie burn. In reality, human energy expenditure divides mathematically as:
