Thank you for sharing your knowledge!!!! I have few questions ; 1) what is the ρ (g/mm ³)? in the equation of physiological cross sectional area? 2)Also in the same equation for physiological cross sectional area, on the denominator of that equation there is fiber length (mm) times ρ (g/mm ³) correct? But then you said that physiological cross sectional area is related to the maximum force that a muscle can produce. Wouldn't that mean that the more fiber length increases the less maximal force the muscle can produce? (because of the fiber length being on the denominator?). But we know that resistance training causes increases in muscle strength and usually increases in muscle fascicle length (especially when using eccentric contractions). How is this possible?
