Comparison of Illinois Agility Test Results Between Normal and Overweight Body Mass Index in Basketball Extracurricular Members at SMAN 3 Surabaya

Background: One of the essential components in basketball is agility, both in offense and defense. Basketball players are required to master and carry the ball to the opponent's area using techniques quickly. One of the factors that influence a basketball player's performance is an ideal body, which can be measured by Body Mass Index (BMI). According to a study, excess BMI can affect body movement and flexibility by 9.15%. The Illinois Agility Test involves movements such as turning, zig-zagging, and sprinting around six cones arranged in a "T" shape.
Purpose: This study aims to compare the results of the Illinois Agility Test between normal and overweight BMI in basketball extracurricular members at SMAN 3 Surabaya.
Materials and Methods: This research is a comparative non-experimental study, with subjects being members of the basketball extracurricular at SMAN 3 Surabaya. The measurement tools used in this study are the Illinois Agility Test for agility and Body Mass Index (BMI). Data analysis was conducted using IBM SPSS Statistics 23, where the normality test used was Shapiro-Wilk, the homogeneity test was Levene's Test for Equality of Variances, and the hypothesis test was Independent Sample T-Test.
Results: The normality test results showed p > 0.05, indicating that the data in this study were normally distributed. The homogeneity test showed p > 0.05, indicating that the data were homogeneous. The Independent Sample T-Test results showed a p-value of 0.002 (p < 0.05), indicating a significant difference between the Illinois Agility Test results of those with normal BMI and those with overweight BMI.
Conclusion: There is a significant difference in the Illinois Agility Test results between individuals with normal BMI and those with overweight BMI.
