■羽毛球运动员的运动表现在很大程度上取决于动态姿势控制在进行高节奏运动时迅速恢复平衡的能力(例如,频繁的单腿跳跃)。我们的目的是研究一种新颖的干预措施的效果,该措施结合了不稳定表面的平衡训练和平衡训练对跳跃后恢复平衡的表现。以及优秀羽毛球运动员的相关姿势控制。
■16名精英男子羽毛球运动员被随机分配到一个平衡和平衡训练组合组(CT,n=8)或增度训练组(PT,n=8)。CT组参加了为期六周的培训,其中包括每周三次培训。每个课程包括40分钟的补强训练和20分钟的平衡训练。PT组使用与CT组相同的方案进行了定量训练。在整个研究过程中,所有参与者都接受了相同的羽毛球技术训练。在基线和干预后立即,参与者完成了单腿跳跃测试.使用着陆后的稳定时间(TTS)评估恢复平衡的能力;还记录了相关的压力中心(COP)波动。通过方差分析的双向重复测量检查干预的效果。
■主要的双向重复测量方差分析模型在优势腿稳定时间(D-TTS)或非优势腿稳定时间(N-TTS)(p>0.70)(p>0.70)。时间的重大主要影响,group,以及它们在前-后位移差(D-COPAP)的优势腿上的相互作用(时间:p=0.001;组:p=0.001;相互作用:p=0.014),非优势腿的前后位移差(N-COPAP)(时间:p<0.001;组:p=0.003;相互作用:p=0.021)和非优势腿的内外侧位移差(N-COPML)(时间:p<0.001;组:p<0.001;相互作用:p=0.026),也就是说,与两组的基线和PT后相比,CT后COP指标显著降低.其次,在CT和PT组中,干预之后,与基线相比,N-TTS(CT:p=0.001,post:0.58±0.87;PT:p=0.03,post:0.71±0.11)显著降低(CTpre:0.76±0.16;PTpre:0.88±0.13)。
■这项试点研究表明,与仅PT相比,结合平衡训练的6周CT在单腿跳跃着陆后恢复平衡的能力方面有相当的改善,并显着改善了通过COP指标衡量的姿势控制性能。
UNASSIGNED: The athletic performance in
badminton players largely depends on the capability of dynamic postural control to quickly restore balance when performing high-paced movements (e.g., frequent single-leg jumps). Our aim was to examine the effects of a novel intervention that combines balance training on an unstable surface and plyometric training on the performance of restoring balance after jumping, as well as related postural control in elite
badminton players.
UNASSIGNED: Sixteen elite male
badminton players were randomly allocated to either a combined balance and plyometric training group (CT, n = 8) or a plyometric training group (PT, n = 8). The CT group participated in a six-week training program, which included three training sessions per week. Each session comprised 40 min of plyometric exercises and 20 min of balance training. The PT group underwent plyometric training using the identical protocol as that of the CT group. All participants underwent identical technical training in
badminton throughout the duration of the study. At baseline and immediately after the intervention, participants completed a single-leg jumping test. The capacity to restore balance was evaluated using the time to stabilization (TTS) after landing; and the related center of pressure (COP) fluctuations were also recorded. The effect of intervention was examined by two-way repeated-measures of ANOVA.
UNASSIGNED: The primary two-way repeated-measures ANOVA models showed no significant interactions between group and time on either the time to stability in the dominant leg (D-TTS) or the time to stability in the non-dominant leg (N-TTS) (p > 0.70). Significant main effects of time, group, and their interactions on dominant legs of the anterior-posterior displacement difference (D-COPAP) (time: p = 0.001; group: p = 0.001; interaction: p = 0.014), non-dominant legs of the anterior-posterior displacement difference (N-COPAP) (time: p < 0.001; group: p = 0.003; interaction: p = 0.021) and non-dominant legs of the medial-lateral displacement difference (N-COPML) (time: p < 0.001; group: p < 0.001; interaction: p = 0.026), that is, compared to baseline of both groups and post PT, the COP metrics were significantly reduced after CT. Secondarily, within the CT and PT group, after the intervention, the N-TTS (CT: p = 0.001, post: 0.58 ± 0.87; PT: p = 0.03, post: 0.71 ± 0.11) was significantly decreased compared to baseline (CT pre: 0.76 ± 0.16; PT pre: 0.88 ± 0.13).
UNASSIGNED: This pilot study demonstrated that, compared to PT-only, the 6-week CT which combines balance training induced comparable improvements in the capacity to restoring balance after landing from a single-leg jump, and significantly improved the postural control performance as measured by COP metrics.
