          </h4>

          <p>
            速度滑冰是以冰刀为工具在冰上进行的竞速运动，起源于 11—12
            世纪的荷兰、英国、
            瑞士等国家。速度滑冰因技术要求高、战术多变、竞争激烈、比赛气氛浓厚等特点，迅速在
            更多国家得到发展与普及。速度滑冰可发展反应速度、绝对力量、速度力量、力量耐力和爆
            发力等身体素质，可有效提高身体的平衡与协调能力、关节灵活度和上下肢力量，不仅可以
            帮助同学们培养坚持不懈的精神，还可锤炼不畏困难、团队合作等意志品质。速度滑冰于
            1924 年被列为冬季奥运会的正式比赛项目。2022
            年北京冬奥会的举办，开启了我国乃至全 球冬季运动的新时代。

          </h5>
          <p>
            本模块设置了速度滑冰运动中最为基础的前置内容——冰性适应。其中，单项技术学练
            包括陆上基本姿势、安全摔倒与站起、冰上原地基本姿势、冰上步伐、滑跑姿势；组合技能
            练习设置的是陆上收引腿 + 摆臂练习、冰上原地收引腿 +
            摆臂练习，以及课程平台中的重心
            移动技术、侧蹬回收技术、单脚支撑技术。同学们学练本模块的内容能提高基本的技术水平，
            为参与本模块设置的比赛提供保障，为后续模块的学练奠定基础。
          </p>

          <p>
            刚上冰的人，穿上冰刀之后不太容易保持身体平衡。由陆上转为冰上进行的适应性练
            习动作被称为冰性适应。学滑冰不是从某个动作开始的，而是从熟悉冰面环境开始的，要让
            身体多种感官对冰面摩擦力有一个适应过程。熟悉冰面的目的是适应冰面环境，消除畏惧
            心理。

              作，滑动起来后保持双腿触冰滑行。在身体前倾时开始蹬冰，先伸展髋关节，同时膝前压，
              踝关节略有缩小；在蹬冰最大用力阶段，使冰刀位于身体侧方，身体倾斜达到最适宜角度，
              膝关节快速伸展，同时伸展髋、踝关节；在结束阶段，要使髋、膝、踝三关节完全伸直。

              入小弯道时，从直道入弯道的最后一步是右腿，在距离小弯道 里侧线 1~2

              道区，后半步在弯道区，随着完成收回左腿动作，身体要大胆地向
              左倾斜。当倾倒到一定程度时，左脚冰刀尽量靠近右腿冰刀，用外刃贴近雪线。当右脚冰刀
              下刀时，身体重心偏后，注意团身；在入弯道前要略加力量，以获得最大的初速度。

          </h4>
          <p>高山滑雪是滑雪者利用雪板、雪鞋、雪杖等雪具，根据旗门设定的赛道，从山上至山下
            滑行的雪上竞速运动项目，起源于阿尔卑斯山脉地区，1936 年被列为冬季奥运会项目。滑
            雪运动容易受气候因素的影响，滑雪者需要适应多变的气候。高山滑雪的滑行方法变化多样，
            不仅可以帮助同学们发展协调性、灵敏性、柔韧性、耐力等身体素质，还能有效提高同学们
            的心肺功能、关节灵活度和上下肢力量，对心理素质较弱、畏寒体质的人有较大帮助。同学
            们在学练滑雪的过程中应不畏挑战，不断体认自我，磨炼意志。</p>

          </h5>

          <p>本模块设置了高山滑雪运动中最为基础的前置内容——雪上适应。其中，单项技术学练
            包括安全摔倒与站起、双板原地练习、雪地行走、蹬坡技术；组合技能练习包括平地走滑 +
            向后转 + 平地走滑、平地走滑 + 八字蹬坡。这些练习能提高初学者基本的技术水平，为参与
            本模块设置的比赛提供保障，为后续模块的学练奠定基础。</p>
          <p>初学者会对滑雪板的长度和重量很不适应，在雪上总有站不稳的感觉，需要先在平缓的
            雪面上进行一些雪上适应练习，提高后续练习效果，防止意外损伤。</p>

            （2）学练建议
            <p>①不穿雪板，两腿左右移动，进行屈伸练习。</p>
            <p>②穿上雪板，进行重心移动练习。</p>
            <p>③只进行一个转弯的平行转弯练习。</p>
            <p>④拓展练习：设置旗门，改变转弯半径大小、滑行速度。</p>
