研究目的：设计一套BOSU球训练方案对体育舞蹈艺考生进行运动处方干预，检验BOSU球训练对于体育舞蹈艺考生平衡能力和专项技术水平的提升效果 ，以期为提高体育舞蹈艺考生平衡能力探寻科学有效的训练方法和手段。

研究方法：(1)本研究基于动力学稳定原理、体适能训练、运动医学等理论设计一套BOSU球的训练方案，且基于适时恢复、肌肉适应等原则将训练部分划分为动态平衡能力、静态平衡能力和核心力量训练三个模块。(2)在泰安某艺术学校54名学生中选取20名体育舞蹈艺考生作为实验组，在淄博某学校36名学生中选取20名体育舞蹈艺考生作为对照组。实验组进行8周的BOSU球训练干预，3次/周，30min/次；对照组进行常规训练，无任何BOSU球干预。干预前后分别对两组动态平衡能力（YBT测试）、静态平衡能力（闭眼单脚站立、单脚站立BOSU球）、核心力量（仰卧起坐、俯卧背起、侧卷腹）和专项技术水平（定点转、自编动作组合、前进走步接SPIRL-SPIN-SPIRL）等指标进行测试。采用独立样本t检验比较干预前后各指标的组间差异，采用配对样本t检验比较干预前后各指标的组内变化差异。

研究结果：（1）实验前静态平衡能力（闭眼单脚站立、BOSU球单脚站立）、动态平衡能力（ YBT测试）、核心力量（仰卧起坐、俯卧背起、侧卷腹）和专项技术水平（定点转、自编动作组合、前进走步接SPIRL-SPIN-SPIRL）各指标两组之间无显著性差异，基线同质（P>0.05）。（2）经过8周的BOSU球训练，与干预前相比，实验组体育舞蹈艺考生的静态平衡能力、动态平衡能力、核心力量和专项技术水平各指标均得到显著改善（P<0.01）。其中，静态平衡能力：闭眼单脚站立、单脚站立BOSU球均显著提升（P<0.01）；动态平衡能力：左脚和右脚YBT均显著提升（P<0.01）；核心力量：仰卧起坐、俯卧背起、侧卷腹显著提升（P<0.01）；专项技术水平：定点转、自编动作组合、前进走步接SPIRL-SPIN-SPIRL均显著提升（P<0.01），而对照组各指标无显著性变化（P>0.05）。（3）与对照组相比，实验后实验组各指标均显著高于对照组（P<0.05）。其中，静态平衡能力：实验组闭眼单脚站立、单脚站立BOSU球成绩均显著高于对照组（P<0.05）；动态平衡能力：实验组左脚YBT测试显著高于对照组（P<0.05）；核心力量和专项技术水平：实验组仰卧起坐、俯卧背起和侧卷腹以及专项技术水平（定点转、自编动作组合和前进走步接SPIRL-SPIN-SPIRL）各指标均显著优于对照组（P<0.05）。

研究结论：8周BOSU球训练能有效提高体育舞蹈艺考生动、静态平衡能力，改善其身体姿态控制能力，提高其运动技术水平，为体育舞蹈艺考生竞技能力和考试成绩的提升提供有益支持。

Objective: This study designed a set of BOSU ball training program for sports dance art examinees exercise prescription intervention, test BOSU ball training for sports dance art examinees balance ability and special project technical level effect, in order to improve sports dance art examinees balance ability to explore scientific and effective training methods and means.

Research methods:(1) This study designed a BOSU ball training program based on the principles of dynamic stability, physical fitness training, sports medicine and other theories, and divided the training part into three modules: dynamic balance ability, static balance ability and core strength training based on the principles of timely recovery and muscle adaptation. (2) 20 sports dance art candidates were selected from 54 students in Shandong Honghu Art School as the experimental group and 20 sports dance art candidates were selected from 36 students in Zibo Art School as the control group. The experimental group received 8 weeks of BOSU ball training intervention, 3 times/week, 30 minutes/time; the control group only carried out routine training without any BOSU ball intervention. Before and after the intervention, the dynamic balance ability (YBT test), static balance ability (standing on one foot with eyes closed, standing on one foot BOSU ball), core strength (sit-ups, prone back-ups, side curls) and special project technical level (fixed-point rotation, self-made action combination, forward walking connected to SPIRL-SPIN-SPIRL) were tested in the two groups. Independent sample t-test was used to compare the inter-group differences of each index before and after the intervention, and paired sample t-test was used to compare the intra-group changes of each index before and after the intervention.

Research findings:(1) Before the intervention, there was no significant difference between the two groups in static balance ability (standing on one foot with eyes closed, BOSU ball standing on one foot), dynamic balance ability (YBT test), core strength (sit-ups, prone back-ups, side curls) and special project technical level (fixed-point rotation, self-made movement combination, forward walking connected to SPIRL-SPIN-SPIRL), and the baseline was homogeneous (P>0.05). (2) After 8 weeks of BOSU ball training, compared with before the intervention, the static balance ability, dynamic balance ability, core strength and special project technical level of the experimental group of physical dance students were significantly improved (P < 0.01). Among them, the static balance ability: closed eyes standing on one foot, standing on one foot BOSU ball significantly improved (P<0.01); dynamic balance ability: left foot and right foot YBT significantly improved (P<0.01); core strength: sit-ups, prone back-ups, side curls significantly improved (P<0.01); special project technical level: fixed-point rotation, self-made action combination, forward walking connected to SPIRL-SPIN-SPIRL significantly improved (P<0.01), while the control group did not have a significant change in each index (P>0.05). (3) Compared with the control group, the experimental group after the intervention, each index was significantly higher than the control group (P<0.05). Among them, static balance ability: the BOSU ball performance of the experimental group was significantly higher than that of the control group (P<0.05); dynamic balance ability: the left foot YBT test of the experimental group was significantly higher than that of the control group (P<0.05); core strength and special project technical level: the experimental group sat up, prone back up and side curl up and special project technical level (fixed point turn, self-made action combination and forward walking connected SPIRL-SPIN-SPIRL) were significantly better than the control group (P<0.05).

Research conclusions: The 8-week BOSU ball training designed by this research institute can effectively improve the physical balance ability of sports dance examinees, improve their sports skills, and provide beneficial support for the improvement of art examinees' competitive ability and competitive performance.
