Abstract

This study aims to evaluate the effect of High-Intensity Interval Training (HIIT) on improving physical endurance performance and reducing the risk of injury in football players. This study utilizes a quasi-experimental design with a one-group pre-test and post-test approach involving 20 football players aged 18 to 25. Resistance performance is measured through VO₂ Max, while injury risk is assessed using body functional tests that evaluate muscle imbalances and biomechanical weakness. After undergoing the HIIT program for 8 weeks, the results showed a significant improvement in the players' VO₂ Max from an average of 61.87 ± 6.03 ml/kg/min to 63.60 ± 6.03 ml/kg/min, with an increase of 2.8% (p < 0.05). In addition, the risk of injury also decreased from an average of 4.11 ± 0.86 to 4.07 ± 0.86, with a decrease of 1.1% which was also statistically significant (p < 0.05). The increase in VO₂ Max reflects the increase in the player's cardiovascular endurance, which is crucial for dealing with the physical demands of a football match. The research also reveals that the reduced risk of injury suggests that HIIT effectively improves muscle stability, flexibility, and balance, which are important in preventing muscle and joint injuries in football players. In conclusion, HIIT is an efficient and effective training method to improve physical performance and reduce the risk of injury, so it is recommended to be applied in the training program of football players

Abstract

Abstract: This study aims to determine the influence of recitation method and motivation on the achievement of learning This study used quantitative methods with three variables, namely the recitation method (X1), Motivation (X2) and Learning Achievement (Y), the number of populations in this study was 180, then the researcher found 50 sempel taken using the Stratifed random sempilng formula. Data collection using questionnaire and documentation methods. Analysis of the instrument includes validity tests and reliability tests with Cronbach's. The analysis uses multiple linear regression analysis. Based on the analysis process, the magnitude of the influence of the recitation method and motivation on natural science learning achievement is shown from the magnitude ofthe coefficient of determination (R Square) value of 61.4% while the remaining 38.6% of natural science learning achievement is influenced by other factors that are not explained in this study. The results found that there was a significant influence of recitation methods and motivation on student achievement in natural science subjects. This means that the recitation method accompanied by motivationwill make students more active in learning.
