The purpose of this study was to evaluate the relationships of body mass index (BMI), years of sport-specific training, power, and reaction time with simple agility measured in tennis players. Thirty participants were recruited from local tennis teams and clubs in Ithaca, NY. Participants performed an Agility T-Test, a 505 Agility Test, a Vertical Jump Test and a Reaction Time Test in the Biomechanics Lab at Ithaca College. Multiple regression analysis revealed that BMI, years of training, PPO and reaction time best predicted agility time for both the 505 Agility Test (R2 = 0.48) and Agility T-Test (R2 = 0.64)
