The purpose of the present study was to examine the effect of KT on 30 m sprint and
counter movement jump performance in active children. Methods. A randomized crossover,
pretest/posttest repeated measures design was used to compare the effects of KT on triceps
surae and no taping. To generate the random assignment sequence, the data collection
sheets were randomly marked with a small letter a or b alternatively. Only the KT
practitioner knew that these letters corresponded to one of the two groups. The two
sessions were separated for three days to avoid accumulation of the KT effects and took
place on the same public sports track. Of the 28 healthy active children (12 girls and 16
boys) enrolled in a triathlon school, all children voluntarily participated in the present study.
Results. The results of the ANOVA on the average obtained in the counter movement jump
test showed differences statistical significant a favor of KT condition [F(1, 19) = 12.383, p =
0.002; η2 = 0.395; P = 0.916]. However, the ANOVA results on the average obtained in the
sprint test did not show differences statistical significant in 0-15 m, 15-30 m, and 0-30 m.
Conclusions. KT on the triceps surae does not seem to affect the sprint performance in
apparently healthy active children, but it does on the counter movement jump test. The KT
application did not cause any discomfort or injury to the children during the study.
