Training-related performance changes on maximal isometric leg extension strength from pre to post testing. Note: Error bars indicate the standard deviation of the mean training load; * indicates a significant difference (p ≤ .05), ** indicates a highly significant difference (p ≤ .001); Cohen’s d values ≤ .49 indicate small, .50 ≤ d ≤ .79 medium and ≥ .80 large effects; M-SRT = machine based stable resistance training; M-URT = machine based unstable resistance training; F-URT = machine based unstable resistance training
