Metabolic Calculations in Sports Medicine

Flashcards capturing key concepts from the lecture on metabolic calculations and their application in sports medicine.

Metabolic Calculations

Methods used to estimate energy expenditure and oxygen consumption during physical activities.

CRF

Cardiorespiratory Fitness, reflecting the integrated function of the heart, blood vessels, lungs, and muscles.

Absolute O2 Consumption

Volume of oxygen consumed per unit of time, expressed in liters per minute (L·min−1).

Relative O2 Consumption

Volume of oxygen consumed per kilogram of body mass per minute, expressed in mL·kg−1·min−1.

METs

Metabolic equivalents; a measure of energy expenditure, where 1 MET equals 3.5 mL·kg−1·min−1.

Energy Expenditure

The amount of energy that a person uses during physical activities, expressed in calories (kcal).

Oxygen Cost

The amount of oxygen required to perform a specific physical activity, which can be converted to energy expenditure.

RER (Respiratory Exchange Ratio)

The ratio of carbon dioxide produced to oxygen consumed, used to assess fuel utilization (carbohydrates vs fats).

Caloric Expenditure

The amount of energy expressed in calories that is burned during an activity.

HRR (Heart Rate Reserve)

Method of estimating exercise intensity using the difference between maximal heart rate and resting heart rate.
