Twitch peak force (A), time to peak (B), half relaxation time (C) and maximum specific force (D) in the controls and maternal steroid treatment groups of 2 d, 7 d and 21 d postnatal age (n = 6 for each group). Values are Mean (SE). White and black bars refer to the control and steroid treatment groups respectively. * ∧ # indicates p<0.05 compared with controls of 2 d, 7 d and 21 d respectively. TTP: time to peak; ½ Relax: half relaxation time.
