The relationship between limb length and lower-limb explosive power on squat-style long jump performance in junior secondary students
Karina Octaviani1, Siti Nurrochmah21. State University of Malang , ID2. State University of Malang , ID2025-07-01|page 103-114AbstractBackground: To determine the relationship between leg length and leg muscle explosive power with squat style long jump performance applied to junior high school students.
Objectives: This study examines the relationship between leg length, leg muscle explosive power, and the ability to jump squatting style long.
Methods: The method used is a quantitative descriptive design with a correlational study. The study population amounted to 60 male students in class VIII. Sampling using the Purposive Proportional Systematic Random Sampling technique amounted to 45 students. The collected data were analyzed using three prerequisite tests: data normality test, homogeneity test, and linearity test. After fulfilling the prerequisite test requirements, it can be continued with 4 hypothesis tests, product moment test, multiple correlation test, regression equation line, and practical contribution and relative contribution.
Results: The data obtained using inferential statistics in multiple correlation analysis is complemented by multiple regression analysis. The results of the multiple correlation test obtained a coefficient = 0.687 and Sig. P = 0.001 < a = 0.05.
Conclusions: The study concludes a positive and linear relationship between leg length and leg muscle explosive power with squat-style long jump performance. Based on these findings, further research is recommended to explore additional variables such as speed, flexibility, and confidence, which may influence squat-style long jump performance.

The effect of game-based learning variations on elementary school students’ straddle jump gymnastics skills
Fadhilah Nurwahid1, Rizal Ahmad Fauzi2, Adang Sudrazat31. Indonesian University of Education , ID2. Indonesian University of Education , ID3. Indonesian University of Education , ID2026-04-01|page 57-67AbstractBackground: Physical education in primary schools is essential for the development of students' motor skills, including gymnastic abilities such as the straddle leap. In fact, numerous students continue to struggle to execute these movements accurately because of repetitive teaching approaches that fail to engage them actively. Consequently, a more stimulating and diverse educational methodology, including game-based activities, is required.
Objectives: This study examines the impact of fluctuations in game-based learning on the enhancement of straddle jump gymnastics skills among primary school students.
Methods: This research employed a quantitative methodology using a pre-experimental framework, namely the One-Group Pretest–Posttest Design. The study population comprised all 40 fourth-grade students at Citungku Elementary School, who were sampled using a total sampling technique. Data were gathered via a practical examination of straddle jump movement proficiency, adhering to the Australian Gymnastic Federation's evaluation criteria, which encompass four components: the initiation, propulsion, suspended posture, and landing. The intervention lasted four weeks and included eight sessions featuring activities such as frog leaps, mirror jumps, rope jumping, and hopscotch, all aimed at training the elements of the straddle jump. The Shapiro-Wilk normality test and paired-samples t-test were conducted in SPSS version 27 for data analysis.
Results: The study found an improvement in students' capabilities following the implementation of game-based learning modifications. The mean pretest score of 58.00 rose to 74.76 in the posttest. The paired-samples t-test yielded a t value of -9.894 and a p-value of 0.001 (< 0.05), indicating a significant difference between pre- and post-treatment outcomes. This demonstrates that the executed game activities facilitated improvements in students' motor coordination, push-off strength, body control during floating, and landing methods during the straddle jump movement.
Conclusions: Variations of game-based learning, including frog jumping, mirror jumping, rope jumping, and hopscotch, have demonstrated efficacy in enhancing straddle jumping gymnastics skills among elementary school students while fostering a more dynamic and pleasurable physical learning experience.
