摘要
虽然已有研究表明,不稳定条件下训练可以激活躯干活化,但该效应能否转化为有效的躯干力量长期训练计划尚不明确。另外,平衡训练对于特定关节本体感觉的影响尚不明确。因此,本研究的目的是通过10周核心稳定性训练检测训练对人体联合适应能力影响。43名被试参与了共计10周的核心不稳定训练计划,使用瑞士球和自重抗阻练习,并和对照组(n=17)进行对比。实验组训练后躯干伸展相对峰力矩(PT/W)和总功(TW)分别比训练前上升了23.6%和20.1%,而对照组分别下降了6.8%和6.7%。实验组的躯干相对峰力矩(PT/W)上升了18.1%,而对照组下降了0.4%。膝关节本体感觉训练后上升了44.7%。结论:使用瑞士球,自重抗阻练习的核心稳定性训练,可以较长时间保持训练效果,这将有助于受试者(为参与过该锻炼的人)改善关节本体感觉和核心力量,并能提高其整体健康水平。
Although there are many studies demonstrating increased trunk activation under unstable conditions, it is not known whether this increased activation would translate into meaningful trunk strength with a prolonged training program. Additionally, their effect on specific joint proprioception is not clear. Thus the objective of this study is to examine training adaptations associated with a 10-week instability training program. 43 participants participated in either a 10 week instability-training program using Swiss balls and body weight as resistance or a control group （n = 17）. The trained group increased trunk extension peak torque/body weight （23.6%） and total work output （20.1%） from pre- to post-training while the control group decreased by 6.8% and 6.7% respectively. The exercise group increased their trunk flexion peak torque/body weight ratios by 18.1% while the control group decreased by 0.4%. Knee proprioception improved 44.7% from pre- to post-training. Conclusions： An instability-training program using Swiss balls with body weight as resistance can provide prolonged improvements in joint proprioception and core strength in previously untrained individuals performing this novel training stress which would contribute to general health.
