The main aim of this study is to find the effect of jump-rope training on the physical fitness of 9 to 10 years old
female students. Considering the mentioned objective, 20 volunteered female students of Jahrom are selected as
cases for this study and they are randomly divided into training group and controlling group. The first group,
participated in jump-rope training three sessions per week. This training process continued 15 weeks, while; the
latter group did not participate in any exercise programs and continued with their daily activities. Some factors
related to the physical fitness, such as balance, speed, and agility of the participants are assessed before and after
the training process. Data analysis is performed by using dependent and independent t-test. The results have
demonstrated that the balance, agility, and power of the training group is increased (p0.05). The results have proven that jump-rope training increases the physical
fitness of 9 to 10 years old female students. However, speed seem to be a heritable trait and did not change after the
training process.
