pcsa
allows one to estimate the physiological cross-sectional area of a muscle
pcsa(mass, pennationAngle, fiberLength, density, stringAsFactors = FALSE, ...)
|
Numerical value of the muscle mass, in units of kilograms. |
|
Numerical value of the pennational angle of the muscle, in units of degrees. |
|
Numerical value of the muscle fiber length, in units of meters. Often assumed to be average muscle fiber length. |
|
Numerical value of the muscle density. Defaults to 1060 kg/m^3, a typical value for striated muscles (Biewener 2003) |
See description in Hutchinson et al. (2015) and Sacks and Roy (1982) for more details regarding the calculation of PCSA.
