This study aimed (1) to identify the developmental status of balance and sensory functions in young adolescents as compared to adults and, (2) to explore the effect of Taekwondo (TKD) training on the development of balance and sensory systems in young adolescents.
Cross-sectional controlled trial.
Sixty-six participants including 42 adolescents (21 TKD practitioners, 21 non-TKD practitioners) and 24 adults were tested. The sway velocity of centre of gravity was recorded during standing on the non-dominant leg on a Smart Equitest ® system. The somatosensory, vestibular and visual ratios were also measured with the machine.
Adult participants swayed slower than both TKD and non-TKD adolescent groups during single leg stance with eyes open (p=0.007 and p<0.001, respectively). The TKD adolescent group, in turn, swayed slower than the non-TKD adolescent group (p<0.001). Adult participants had better visual ratio than both TKD and non-TKD adolescents (p=0.001 and p<0.001, respectively) while there was no difference between the TKD and non-TKD adolescents (p=0.164). For the vestibular ratio, there was no significant difference between adult participants and TKD adolescents (p=0.432). Adolescents who did not practice TKD showed significantly lower vestibular ratio than TKD adolescents and adults (p=0.003 and p<0.001, respectively). In addition, there was no significant difference in the somatosensory ratio among the 3 participant groups (p=0.711).
Participation in TKD appears to speed up the development of postural control and vestibular function in adolescents. Clinicians might advocate TKD exercise as a therapeutic intervention for young people with balance or vestibular dysfunctions.
本研究旨在:(1) 比较青少年与成年人的平衡和感觉功能发育状况;(2) 探讨跆拳道(TKD)训练对青少年平衡和感觉系统发育的影响。
横断面对照试验。
共纳入 66 名参与者,包括 42 名青少年(21 名 TKD 练习者,21 名非 TKD 练习者)和 24 名成年人。使用 Smart Equitest ® 系统记录非优势腿单腿站立时的重心摆动速度。同时,机器还测量了本体感觉、前庭和视觉比。
成年人在睁眼单腿站立时的摆动速度比 TKD 青少年组和非 TKD 青少年组都慢(p=0.007 和 p<0.001)。而 TKD 青少年组的摆动速度又比非 TKD 青少年组慢(p<0.001)。成年人的视觉比优于 TKD 青少年组和非 TKD 青少年组(p=0.001 和 p<0.001),而 TKD 青少年组和非 TKD 青少年组之间没有差异(p=0.164)。对于前庭比,成年参与者与 TKD 青少年组之间无显著差异(p=0.432)。非 TKD 青少年的前庭比明显低于 TKD 青少年和成年人(p=0.003 和 p<0.001)。此外,3 组参与者的本体感觉比无显著差异(p=0.711)。
参加跆拳道似乎可以加快青少年姿势控制和前庭功能的发展。临床医生可能会提倡 TKD 运动作为治疗平衡或前庭功能障碍的年轻人的治疗干预措施。
