Computerized tomography: a method to study cross-sectional muscle area in nutritional evaluation.

We have compared two ways of determining cross-sectional muscle area in patients undergoing total parenteral nutrition, namely, computerised tomography and anthropometric measurements. There was a poor correlation between the two methods of determining cross-sectional limb area. The cross-sectional area increased in all patients considered on clinical grounds to have improved during the course of treatment.

Muscle fibre type distribution, muscle cross-sectional area and maximal voluntary strength in humans.

The relationship between maximum voluntary concentric strength, muscle fibre type distribution and muscle cross-sectional areas were examined in 23 subjects (7 female and 11 male phys. ed. students as well as 5 male bodybuilders).
