This investigation examined the effects of plantar flexion (PF) stretching on flutter kicking time in competitive swimmers. A single blind randomized control study was performed with 19 male and female Wichita Swim Club members (13-17 years old), who were divided into two groups: control or stretching. The stretching group performed PF stretches five times a week for 15 minutes a day. Pre-test measures for PF and 50 yard flutter kicking times were recorded initially then retested after four weeks. Results showed a small significant difference between PF stretching versus no stretching on flutter kicking speed in competitive age group swimmers.
