Cardiac function in the sedentary control (C), exercise control (E), sedentary 5/6Nx (NxS), and exercise 5/6Nx (NxE) groups.

Results are expressed as the mean ± SEM (n = 8 per group). LVW/BW, left ventricle weight divided by body weight; CW/BW, cardiac weight divided by body weight; LVPWd, diastolic LV posterior wall thickness; LVPWs, systolic LV posterior wall thickness; LVAWd, diastolic LV anterior wall thickness; LVAWs, systolic LV anterior wall thickness; +dP/dt, maximum positive time derivative of developed pressure; –dP/dt, maximum negative derivative of developed pressure.*p#p&p
