Glossary

Plain-language explanations of the tests, measures, therapies, and concepts used in longevity medicine.

B

Biomechanical Assessment

A biomechanical assessment is a structured observation and measurement of how forces, joints, and body segments interact during movement or posture.

Body Composition

Body composition describes the relative amounts and distribution of fat mass, lean soft tissue, and bone mineral in the body.

D

DEXA Scan

A DEXA scan is a low-dose X-ray assessment used to estimate bone mineral density and, with suitable software, body composition.

E

Epigenetic Age

Epigenetic age is a model-derived estimate that uses patterns such as DNA methylation to summarize age-associated molecular variation.

G

Gait Analysis

Gait analysis is the systematic observation or measurement of walking or running patterns across time, distance, joint motion, and force.

Genomic Testing

Genomic testing examines selected parts or broad portions of a person's DNA to identify sequence variants and other genomic features.

Gut Microbiome

The gut microbiome is the collective genetic material and ecological activity of microorganisms living in the gastrointestinal tract.

L

Lactate Threshold

Lactate threshold is an exercise-intensity boundary around which blood lactate begins to accumulate faster than the body can clear or reuse it.

P

Pharmacogenomics

Pharmacogenomics examines how inherited genetic variation may relate to differences in medication processing, transport, targets, or response.

S

Spirometry

Spirometry is a breathing test that measures how much air a person can move and how quickly it can be exhaled.

V

VO2 Max

VO2 max is the highest rate at which the body can take in, transport, and use oxygen during progressively harder exercise.
