摘要:

目的 探讨血流限制下低强度增强式跳跃训练(LI-PJT+BFR)对功能性踝关节不稳(FAI)大学生的下肢动态姿势控制的影响。

方法 2023年3月至5月,招募西安体育学院FAI大学生40例,随机分为高强度增强式跳跃训练(HI-PJT, n = 14)组、低强度增强式跳跃训练(LI-PJT, n = 13)组和LI-PJT+BFR组(n = 13),各组完成相应的干预训练,共6周。干预前后,采用无线遥感表面肌电测试仪测量胫骨前肌、腓骨长肌、腓肠肌外侧头、臀大肌、股外侧肌、股二头肌和半腱肌最大自主等长收缩(MVIC)和单腿下落(SLL)时肌电均方根值(RMS),采用Y平衡和坎伯兰踝关节不稳问卷(CAIT)进行评定。

结果 干预后,除LI-PJT组腓骨长肌、臀大肌、股二头肌和半腱肌MVIC和RMS,LI-PJT+BFR组腓骨长肌RMS外,各组其余肌肉MVIC和RMS均较干预前提高(t > 2.218, P < 0.05);3组中,除腓骨长肌外,LI-PJT组各肌肉MVIC和RMS均最低(F > 3.262, P < 0.05);各组Y平衡各方向评分和综合分均提高(t > 2.485, P < 0.05),3组中LI-PJT组最低(F > 5.042, P < 0.05);各组CAIT评分显著改善(t > 5.227, P < 0.001),3组中LI-PJT组最低(F = 4.640, P < 0.05)。

结论 LI-PJT+BFR可改善功能恢复期FAI大学生下肢动态姿势控制能力,效果与HI-PJT相似。

Abstract:

Objective To investigate the effect of blood flow restriction combined with low-intensity plyometric jump training (LI-PJT+BFR) on lower limb dynamic postural control of functional ankle instability (FAI) in college students.

Methods From March to May, 2023, 40 FAI college students were recruited from Xi'an Physical Education University, and randomly divided into high-intensity plyometric jump training (HI-PJT, n = 14) group, low-intensity plyometric jump training (LI-PJT, n = 13) group and LI-PJT+BFR group (n = 13). All the groups finished the six-week corresponding training. The maximum voluntary isometric contraction (MVIC) of tibialis anterior, peroneus longus, lateral head of gastrocnemius, gluteus maximus, vastus lateralis, biceps femoris and semitendinosus were measured, and the root mean square (RMS) of electromyography of these muscles was measured during the single-leg landing (SLL), using wireless surface electromyography before and after intervention. Moreover, they were assessed with Y-balance test and Cumberland Ankle Instability Tool (CAIT).

Results MVIC and RMS of the target muscles improved after intervention in all the groups (t > 2.218, P < 0.05), except MVIC and RMS of peroneus longus, gluteus maximus, biceps femoris and semitendinosus in LI-PJT group, and RMS of peroneus longus in LI-PJT+BFR group; and MVIC and RMS of the target muscles were the least in LI-PJT group (F > 3.262, P < 0.05), except those of peroneus longus. The extension scores of Y-balance test and the total score improved after intervention (t > 2.485, P < 0.05), and they were the least in LI-PJT group (F > 5.042, P < 0.05). The CAIT score improved after intervention (t > 5.227, P < 0.001), and it was the least in LI-PJT group (F = 4.640, P < 0.05).

Conclusion LI-PJT+BFR could improve lower limb dynamic postural control of FAI college students, which is similar to HI-PJT.
