Muscular power

Physical Performance

Muscular power is the ability to produce force quickly, important for sprinting, jumping, and explosive sport movements.

A common variant in ACTN3 (the R577X variant) has been linked to muscle fiber composition and explosive power performance.

This result reflects research-level variation in power biology and is not a performance test.

Training, sport-specific practice, age, body composition, nutrition, recovery, and skill all strongly shape actual power output.

ACTN3

This gene encodes a member of the alpha-actin binding protein gene family. The encoded protein is primarily expressed in skeletal muscle and functions as a structural component of sarcomeric Z line. This protein is involved in crosslinking actin containing thin filaments. An allelic polymorphism in this gene results in both coding and non-coding variants; the reference genome represents the coding allele. The non-functional allele of this gene is associated with elite athlete status. [provided by RefSeq, Feb 2014]
