Physiological cross-sectional area of muscles (PCSA)

Description

pcsa allows one to estimate the physiological cross-sectional area of a muscle

Usage

pcsa(mass, pennationAngle, fiberLength, density, stringAsFactors = FALSE, ...)

Arguments

mass

Numerical value of the muscle mass, in units of kilograms.

pennationAngle

Numerical value of the pennational angle of the muscle, in units of degrees.

fasicleLength

Numerical value of the muscle fiber length, in units of meters. Often assumed to be average muscle fiber length.

density

Numerical value of the muscle density. Defaults to 1060 kg/m^3, a typical value for striated muscles (Biewener 2003)

Details

See description in Hutchinson et al. (2015) and Sacks and Roy (1982) for more details regarding the calculation of PCSA.
