Lateral cone jump exercises are plyometric, involving jumping over cones while utilizing the Polar H10 assistive device to monitor heart rate intensity during each jump. This study aimed to evaluate the effects of cone jump training on the frequency of jumps and its impact on explosive power in the leg muscles. This type of lateral cone jump training aims to enhance physical conditioning by executing lateral jumps toward cones, with the intensity gauged by the number of cones cleared. High-intensity interval training (HIIT) aims to improve cardiorespiratory fitness, promote fat burning, and increase muscle strength in a relatively short training time. Path analysis was employed for data processing and analysis. The statistical software utilized included SPSS for direct influence and the Sobel Calculator for indirect influence to determine the outcomes of both pre-test and post-test assessments. Following the completion of the lateral interval cone jump exercise by 40 high school female students, it was observed that the variable representing the number of jumps had a statistically significant effect on leg muscle explosive power, with a significance level of 0.040 < a (0.05). The total coefficient of determination derived from path analysis equated to 0.320, indicating that 32% of the variance in leg muscle explosive power among high school sports students could be attributed to the lateral cone jump training variables and the number of jumps, while the remaining 68% could be influenced by other variables not incorporated in the study. Regarding the strength of the research model, the coefficient of determination of 0.32 places it within the moderate or medium category. The positive sign of the coefficient suggests that an increase in the number of jumps correlates with higher explosive power in the leg muscles. This implies that a greater number of jumps contributes to increased leg muscle explosiveness. [ABSTRACT FROM AUTHOR] |
