What does a MET stand for in exercise physiology?

A MET, which stands for Metabolic Equivalent of Task, is a unit used to estimate the amount of energy expended during physical activities compared to resting metabolism. One MET is equal to the caloric cost of sitting quietly, which is approximately 3.5 mL of oxygen consumed per kilogram of body weight per minute. This measurement provides a standardized way to assess various activities in terms of their energy expenditure.

In exercise physiology, understanding MET values allows fitness professionals to categorize activities based on their intensity levels. For example, light activities might use 1-3 METs, moderate activities 3-6 METs, and vigorous activities greater than 6 METs. This helps individuals and trainers tailor exercise programs according to fitness levels and health goals.

The other options do not accurately reflect the established terminology in exercise physiology. Maximum Effective Time, Metabolic Equivalent of Training, and Minimal Energy Threshold do not correspond to the standardized measurement that MET represents. Thus, the correct understanding of MET is critical for professionals in the field to effectively communicate exercise intensities and energy expenditures to clients and improve health outcomes.
