Greater knee muscular strength during high velocity movement among practitioners of taekwondo
Journal Title: Journal of Combat Sports and Martial Arts - Year 2013, Vol 4, Issue 1
Abstract
[b]Introduction. [/b]Taekwondo (TKD) training places emphasis on fast and high kicks. Thus, the practice of TKD may be beneficial for strengthening lower-limb muscles in young people. The objective of our study was to compare isokinetic knee muscular strength between TKD practitioners and control participants during movement at different velocities.[b]Material and methods.[/b] Sixty-eight TKD practitioners and 72 age- and sex-matched control participants were enrolled in our study. Body height and weight were measured using a mechanical scale with an attached height rod. Measurements of the iso-kinetic peak torque for knee extension and flexion were recorded at 60°/s, 180°/s, and 240°/s using a Cybex Norm isokinetic dynamometer.[b]Results.[/b] Results revealed that the isokinetic peak-torque values for knee extension and flexion at 240º/s were 11.5% and 16.6% higher, respectively, in the TKD group than in the control group (P <0 .05). No significant intergroup difference in knee muscular strength was found at the lower angular velocities (60°/s and 180°/s).[b]Conclusions. [/b]The practice of TKD may be beneficial for improving knee muscular strength in adolescents, especially with regard to the repetition of high-velocity movements.
