Abstract

The purpose of this study was to determine the contribution of lower limb explosive power and waist flexibility to the performance of the flop-style high jump among students in the Department of Coaching Education, Faculty of Sports Science, Universitas Negeri Padang (FIK-UNP). This research was motivated by the observed low performance in the high jump, which is suspected to be influenced by insufficient explosive leg power and limited flexibility in the waist area. This study employed a correlational research design. The population consisted of 39 students enrolled in an advanced athletics course, comprising 37 male and 6 female students. A total of 37 participants were selected using purposive sampling. The instruments used were: the vertical jump test (using the Lewis formula) to measure lower limb explosive power, the bridge-up test to assess waist flexibility, and a standardized flop-style high jump test to evaluate high jump performance. Data were analyzed using single and multiple correlation techniques, followed by the calculation of the coefficient of determination (R² × 100%) to identify the contribution of each independent variable. The results showed that: (1) lower limb explosive power contributed 61.62% to high jump performance; (2) waist flexibility contributed 30.91%; and (3) both variables together contributed 69.22% to the students' flop-style high jump performance.

Abstract

Motor learning in preschool and school education is very important to pay attention to because it has an impact on children's growth and development, as well as their mental abilities (Komaini et al. 2021). Many challenges Indonesian children face, overweight or obesity and lack of physical activity are two major challenges. More than half (65%) of the world's population lives in countries where overweight and obesity kill many people, identified as the fourth leading risk factor for global mortality(Gallahue 1989). The problem is not limited to adults and nearly 43 million children worldwide under the age of five were overweight in 2010. It is clear we need to look critically and progressively at physical activity and motor skills development. In this service, the service will run basic physical fitness and movement programs that have been adapted to the needs of school and early childhood students in Indonesia, namely the TKJI and INDO-SKIP tests. INDO SKIP is a basic motion learning program that focuses on locomotor motion and control objects that have been proven in improving the quality of children's basic movements. Meanwhile, TKJI is an Indonesian Physical Fitness Test. The target that will be carried out this year is to be able to provide training to kindergarten schools in the region to implement basic movement learning in PAUD and Sipora Middle School, Mentawai Regency. Has collaborated with the Academic community of Padang State University to develop school teachers and Village Kindergarten Teachers. For this reason, it is important to do coaching for these teachers. After training, teachers will provide independent learning about basic movements in accordance with the curriculum that has been prepared for kindergarten students.
