Method: 35 healthy college students were recruited and arranged to different MoI groups for 6weeks training. Maximal voluntary contraction (MVC) force, isometric contraction peak torque (ICT) of quadriceps muscle were obtained. Two-way analysis of variance (mixed design) was processed. Significant level was set at (=.05. Results: Significantly improve after 6 weeks training upon MVC, ICT of eccentric contraction on high and low testing speed, and concentric contraction on high testing speed. There is no difference between groups. Mean power frequency and middle frequency were both lower. Concussion: Inertial resistance training can enhance lower limb strength especially in high speed movement and eccentric performance. And training should use maximal voluntary velocity whether the MoI. However, which training velocity is the most efficiently still unknown and will need further research.
