Muscle thickness of the rectus femoris (a) and the vastus intermedius (b) assessed prior to and after four sets of unilateral eccentric knee extensions that were performed until volitional muscle failure either with (squares) or without (circles) blood flow restriction. Data are presented as means with 95% confidence intervals. No significant group by time interactions were observed for the muscle thickness of the rectus femoris and the vastus intermedius. Therefore, asterisks above horizontal lines spanning adjacent bars indicate that this measurement time point significantly different from pre, collapsed across groups
