The purpose of this study was to assess whether measurements of thigh bulk taken with a tape measure would give an indication of muscle power. Eleven male patients, all undergoing unilateral menisectomies, performed exercises of the quadriceps and hamstring muscles during concentric loading at 60°/s. The patients were tested three times over a 12-week period: one day before the operation and 2 and 12 weeks after the operation. Thigh girth was recorded, using a conventional plastic tape measure, 10 cm from the top of the patella in each of the three test sessions. The results of this study demonstrated that muscle power cannot be predicted from thigh girth measurements.
