为探讨三小球运动对上肢优势侧和非优势侧的差异性影响特点,采用文献资料法、测量法、观察法、数理统计法等研究方法,从机能形态学的角度,以科学的体育测量和评价技术为基础,分别对18~21岁三小球运动员和普通人优势侧与非优势侧的各项指标进行测量、对比和分析,认为:三小球运动对人体优势侧与非优势侧围度形态指标(上臂紧张围、上臂放松围、前臂围)、握力、简单反应时、肌含量、脂肪率指标差异性影响显著;距离运动反应时指标上,乒乓球、羽毛球两侧差异性明显,网球两侧差异不具有显著性;三小球运动员优势侧上肢骨径较粗、骨小梁排列紧密,存在不同程度的脊柱侧弯问题。建议:早期从事三小球专项运动训练的运动员一定要重视非优势侧的训练;教练员在进行三小球教学过程中,将三小球运动易引起两侧非对称发展的现象作为教学内容进行讲解,适当安排非优势侧技能与素质教学发展。
In order to explore the difference of the influence of three-ball game on the dominant side and the non-dominant side of the upper limb, this paper adopts the methods of literature, measurement, observation, mathematical statistics and other research methods. From the perspective of functional morphology, And evaluation techniques, we measured, compared and analyzed the indexes of dominant side and non-dominant side of junior golfers 18-21 years old and ordinary people, respectively, and concluded that the influence of tri-ball exercise on the dominant side and non-dominant side There were significant differences in the indexes of body shape and fat content (girth of the upper arm, relaxation of the upper arm, forearm circumference), grip strength and simple response; There was no significant difference between the two sides of the tennis ball. The superiority of the upper limbs of the junior golfers was thicker and the trabecular was arranged in close proximity. There were some problems of scoliosis. It is suggested that the athletes who are engaged in the special training of three balls in the early stage must pay attention to the training on the non-dominant side. During the course of teaching the three balls, the coaches can easily cause the asymmetric development of both sides as the teaching content Explain, appropriate arrangements for non-dominant side skills and quality of teaching and development.
