对我国优秀男子三级跳远运动员跨步跳起跳三时相运动学参数的研究

运用定点高速录像(250帧/ s)的方法,对我高优秀男子三级跳远运动员跨步跳起跳过程中三时相(着地、缓冲、蹬伸)运动学参数进行了定量分析.分析结果表明:跨步跳起跳过程中,着地角、起跳幅度、着地时重心高度、离地时重心高度、离地时两大腿夹角对跨步跳离地时水平速度影响较大,是造成跨步跳阶段水平速度损失大的主要原因.我国优秀男子三级跳远运动员跨步跳起跳过程中,过分屈膝,蹬伸迟、不充分,摆动动作消极,不能有效地提高腾起初速度,提高起跳效果.

Should Children Attend Their Parent's Funerals?

The paper discusses elements of the findings of 'Iceberg', a doctoral study at the University of York addressing many issues of child bereavement through a retrospective study of nearly one hundred individuals who had either experienced the death of a parent when they were at school, or were the surviving parent of such a child. The research revealed issues of lack of control and information for children after a parental death. Forty-seven per cent of those in the study attended the funeral of their parent. There was correlation between the age of children and attendance at the funeral. Of the fifty-three per cent of children not attending, twenty-four per cent of them were forbidden to attend, whilst eleven per cent of them were distracted from attending the funeral, such as being sent to school or a neighbours and being unaware that it was taking place. None of the children attending the funeral reported any negative experiences, and two thirds of them reported it as a positive or helpful event. In contrast, over three-quarters of those not attending later wished that they had. Over a third had feelings of regret, others feeling that they had been excluded from the family at the time of the death, and felt anger, hurt, and frustration. The conclusion was that the best strategy is to give children informed choice about whether or not to attend. If children do attend a negative outcome seems unlikely, but it would be prudent to prepare them as to what to expect at the ceremony.
