| Summary: | <p>Wearable resistance (WR) is used in sport training with the aim of increasing</p><p>performance by enabling sport-specific movements to occur with additional loading.</p><p>Despite of its potential of allowing athletes to move more specific, studies examining</p><p>WR during kicking in Taekwondo is scarce. The purpose of this study is to determine</p><p>the effects of WR loading on the biomechanics of axe kick. Thirty (N=30) university</p><p>taekwondo athletes have been recruited as participants in this study. This study requires</p><p>the participants to undergo the middle axe kick testing with WR loading worn at lower</p><p>body (0%, 5%, 10%, and 15% of body mass) during the execution. High-speed motion</p><p>capture system was used to analyse kinematic data (kicking velocity, kicking time,</p><p>kicking height, hip angle and leg displacement). Force plate was used to measure</p><p>ground reaction force (GRF) while electromyography was used to determine muscle</p><p>activation (vastus lateralis, rectus abdominis, gastrocnemius medial, gluteus maximus</p><p>and bicep femoris muscle) during the kick. Results showed there was a significant</p><p>change in kicking kinematics (kicking time was longer, decrease in kicking velocity,</p><p>the kicking became shorter, hip angle and leg displacement decrease) as the WR load</p><p>increased. There was a significant increase of GRF on the supporting leg as WR loads</p><p>attached increased. All muscle activation also increased with loading but no significant</p><p>differences found. In conclusion, WR loadings of 5% body mass and higher at lower</p><p>body affected the biomechanics of the middle axe kick. Although had mechanically</p><p>affect the movement, future studies are suggested to investigate the chronic effects of</p><p>these loadings. The implications of this study can be used as a guideline to choose</p><p>proper WR loading to be used in training.</p> |
