The effect of a protein-deficient diet non-supplemented or supplemented with vitamin B₆ on selected organs and tissue weights in the exercised and unexercised rats. Rats were fed for 90 days the control diet (20% of energy from protein, groups I and II), low-protein diet (4.5% of energy from protein, groups III and IV), or low-protein diet (4.5% of energy from protein) supplemented with 300% of vitamin B₆ (groups V and VI). ^{a, b, c, d} – the level of divergence between groups (p < 0.05). Each group consisted of 10 animals
