The effect of strapping on changing the velocity of punching and kicking in Muay Thai boxer
Abstract:
This study was designed to examine the effects of strapping on tape on movement
time and velocity of punching and kicking in boxers. The subjects participated were 24 males
and were divided as inclusion criteria into two groups, non-boxer group and boxer group. The
non-boxer group was 12 students from the College of Sports Science and Technology of
Mahidol University, who played volleyball, basketball and football. The other group was
boxers from Kai Sasiprapa Gym. None of the subjects had a history of severe injury or being
knocked-out up to 6 months before investigation. After the subjects rested, their physical
fitness was tested. After these measurements, the subjects were allowed to rest about 15
minutes. Then the subjects were tested for response to various stimulus directions, and
various target directions. The response time was compared in 1st and 2nd degrees of strapping
and directions of movement. The response time of kicking was measured using the same
double reaction timer. The results showed that the mean of range of motion (ROM) of both
groups after a 1st degree strapping of Thai boxers ROM decreased about 14.42% and nonboxers
decreased about 17.06 % in the upper extremity. In the 2nd degree of strapping Thai
boxers ROM decreased about 21.97% and non-boxers ROM decreased about 27.14 % in the
upper extremity. In the lower extremity 1st degree strapping of Thai boxers ROM decreased
about 14.10% and non-boxers ROM decreased about 18.81 %. The 2nd degree strapping of
Thai boxers ROM decreased about 21.87% and non-boxers ROM decreased about 29.86 %.
The decreasing % of ROM in the Thai boxers group was less than non-boxers group which
suggested that the strength of the part of movement has an influence of limiting the ROM.
Thai boxer did regular exercises and were stronger than the non-boxer group. These data
showed that the limitations of movement had no significantly effect on the speed of
movement. The percentage reduction of velocity of punching after strapping of upper
extremity were no different between the 1st and 2nd degree of strapping in non boxers and
boxers. This suggested that the degrees of strapping did not influence the velocity of
punching. Additionally, the punching velocity at 0, 45, and 315 degree in non-strapping, 1st
and 2nd degrees strapping showed similar patterns to that of the boxer group. Punching
velocity was higher in the boxer group than non boxer group. The Thai boxer group had to
significantly higher physical fitness than the non-boxers. It’s suggested that this higher level
of fitness may have helped maintain their punching velocity. However, their kicking velocity
may have decreased due to the chronic leg injuries that many Thai boxers sustain. The nonboxers
velocity with strapping may have increased because they were able to compensate by
using unorthodox techniques. These suggestions would form a good basis for further study
