The aim of this experiment was to investigate: (1) the difference in the effects of shadow training using an application and conventional methods on the agility of badminton athletes; (2) the difference in the effects of high and low muscle endurance on agility in badminton athletes; and (3) the interaction between shadow training methods and muscle endurance on agility in badminton athletes. This is an experimental study conducted to examine how a treatment or independent variable (variable x) affects the dependent variable (variable y). The study was designed as a 2x2 factorial, which involved two or more independent variables combined. The study population consisted of 55 members of the PB. UNJA Jambi club. The sample was selected using stratified and conditional sampling, specifically including individuals between the ages of 12-17 years old and who had a national PBSI ID. The sample was stratified based on leg muscle endurance, measured using the "Wall Squat Test." The data were collected using a leg exercise test instrument with a validity of 0.706 and a reliability of 0.808. The analysis of the study was conducted using Manova with a significance level of 0.05. The results showed that: (1) there was a significant difference in agility between shadow training using an application and conventional methods, with an F value of 38.37 and a significance value of 0.000 < 0.05; (2) there was a significant difference in agility between high and low muscle endurance, with an F value of 59.992 and a significance value of 0.000 < 0.05. The analysis showed that high muscle endurance increased by 1.5 from 15.10, while low muscle endurance increased by 0.40 from 14.10; and (3) there was no significant interaction between the treatment (shadow training using an application and conventional methods) and leg muscle endurance (high and low) on agility, with an F value of 0.634 and a significance value of 0.544 > 0.05.
