Methods: The subjects are 24 sarcopenia elder women who are evenly divided into hydraulic group (HDRE) and control group (CON). Subjects were examined by the senior fitness test, ultrasound and the biodex isokinetic dynamometer. Two factors mixed design (two-way ANOVA) was used to analyze pre- and post-tests between groups, and paired-samples t test was used to analyze pre-, post- and detraining-tests, significant level was set α=.05. Results: After 12 weeks hydraulic-resistance circuit training, the 30 seconds sit to stand test, the 2.44 meters up and go test, the functional reach test and the 2 minutes step were significantly increased. The thickness of rectus femoris (RF) were significantly increased, but fascicle length of the vastus lateralis (VL) was significantly decreased. RFD and impulse were significantly increased. Conclusions: RFD and muscle thickness were increased significantly after 12 weeks hydraulic resistance training. Hydraulic resistance circuit training could be beneficial to neuromuscular system functions. It shows that HDRE training could increase immediately for the recruitment of muscle fibers and be hypertrophy later. Therefore hydraulic circuit training could be the economic way to improve the functional fitness of the elderly women.
