|Outline of Final Research Achievements
The purpose of this study was to elucidate the effect of sling exercise training on muscle cross-sectional area of the psoas major muscles (CSA), and hip flexion torque (HFT) and maximal running velocity (Vmax) in track and fields. Forty-five college sprinters and jumpers were randomly assigned to two groups: training group which conducted a 10-wk sling training (TR, N=23) and control group which trained regular track and field specific training alone (CON, N=22). Before and after the intervention, CSA (MRI), HFT (dynamometer), and Vmax (Laser) were determined. For TR, CSA, HFT and Vmax were significantly increased through the intervention. For CON, there were no significant changes in CSA and Vmax, but the HFT was significantly decrease for 10 weeks. These current results indicate that sling training can be feasible for improving the musculature and force generating capacity of the hip flexors and Vmax, compared to regular sprint- and jump-specific training alone.
