A person lifts a box and the mean rectified EMG recorded from his erector spinae muscles is 2.69 mV. Prior to the lift the same subject performed a maximal effort isometric trunk extension and his rectified EMG was 13.07 mV. What is the subject's normalised erector spinae activity to two decimal places and include the correct unit?
