Balanced capacity plays a very important role in each sport. This study took a total of 36 fifth-grade girls from 3 classes, with each class having 12 participants, in Tainan elementary schools as subjects. These subjects were assigned to soft surface jump training group (trampoline group), stiff surface jump training group (rope skipping group) and control group for training once a week for eight weeks to understand the impact of jump training on different surfaces on the balanced capacity and muscle strength of elementary female students. The subjects took tests on static balanced function (standing with one foot with eyes closed), dynamic balanced function (walking on a balance beam) and muscle strength of lower limbs (standing long jump). Independent sample co-variable analysis was used to compare differences in the balanced capacity among groups (α=.05). It’s found from the results that the soft surface jump training group (trampoline group) and stiff surface jump training group (rope skipping group) were significantly improved (p<.05) in static balanced capacity; The soft surface jump training group (trampoline group) and stiff surface jump training group (rope skipping group) were significantly improved (p<.05) in dynamic balanced capacity; The soft surface jump training group (trampoline group) and stiff surface jump training group (rope skipping group) (p<.05) were significantly improved in muscle strength of lower limbs. Therefore, jump trainings on either soft surface or stiff surface can improve static balanced performance, dynamic balanced performance and muscle strength of lower limbs of these high-grade elementary girls.
