Nature and Nurture

20.3K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

科学领域:

  • 生物力学 生物力学
  • 人体工程学就是人体工程学.
  • 人类运动科学科学 人类运动科学

背景情况:

  • 手动物料处理期间的脊柱运动模式 (SMP) 对于预防伤害至关重要.
  • 现有的研究往往忽略了在举重任务中的性别特异性生物力学差异.

研究的目的:

  • 为了研究性别,人体测量因素和脊柱运动模式 (SMP) 在举起和下降任务期间的关系.
  • 识别与不同的提升技术和人口统计学变量相关的不同SMP.

主要方法:

  • 30名成年人使用自由式,腰和俯卧技巧用一个15公斤的箱子进行了箱子提升/降低.
  • 使用逐步细分方法和对相对角度拐点的分析来对SMP进行分类.
  • 时间多段相互作用及其频率在各段和技术中进行了分析.

主要成果:

  • 脊柱运动模式显示,在举起和降低过程中,与性别和人类学有不同的关联.
  • 在俯卧式举重时,女性主要表现出自下而上的SMP,而男性则倾向于同时举重模式.
  • 集群分析确定了一个自下而上的胸椎脊柱模式是女性的关键差异化因素.

结论:

  • 开发的SMP分类方法可以在举重过程中区分基于性别的运动策略.
  • 这些发现表明,个性化的手动物料处理策略和治疗干预措施的潜力.
  • 这项研究为职业健康,临床康复和体育训练计划提供了见解.
