  • 受疫情影响，2020东京奥运会将延期至2021年举行；

  • 虽然延期，但此次奥运会依旧会沿用「2020东京奥运会」这个名称；

  • 这也将是奥运会历史上首次延期（1916年、1940年、1944年曾因一战，二战停办）；

既然奥运会延期了，那我们就来回顾下整个奥运会的历史吧🎉🎉～

本项目将会从以下角度来呈现奥运会历史：

  1. 🏆各国累计奖牌数；

  2. ⚽️各项运动产生金牌数

  3. ⛳️运动员层面

    • 参赛人数趋势

    • 女性参赛比例趋势

    • 获得金牌最多的运动员

    • 获得奖牌/金牌比例

    • 各项目运动员平均体质数据

  4. 主要国家表现

    • 🇨🇳中国表现

    • 🇺🇸美国表现

  5. 💥被单个国家统治的奥运会项目

累计奖牌数

夏季奥运会 & 冬季奥运会分别统计

  • 🏖️夏季奥运会开始于1896年雅典奥运会；

  • ❄️冬季奥运会开始于1924年慕尼黑冬奥会；

各国夏奥会累计奖牌数

  • 截止2016年夏季奥运会，美俄分别获得了2544和1577枚奖牌，位列一二位；

  • 中国由于参加奥运会时间较晚，截止2016年累计获得了545枚奖牌，位列第七位；

运动员层面

历年参赛人数趋势

  • 从人数来看，每届夏奥会参赛人数都是冬奥会的4-5倍；

  • 整体参赛人数是上涨趋势，但由于历史原因也出现过波动，如1980年莫斯科奥运会层遭遇65个国家抵制；

获得金牌/奖牌比例

看菲尔普斯拿金牌拿到手软，但实际上想获得一块金牌的难度高吗？

  • 整个奥运会（包括夏季，冬季奥运会）历史上参赛人数为134732，获得过金牌的运动员只有10413，占比7.7%;

  • 获得过奖牌（包括金银铜）的运动员有28202人，占比20.93%；

运动员平均体质数据

根据不同的运动项目进行统计

  • 运动员平均身高最高的项目是篮球，女子平均身高达182cm，男子平均身高达到194cm；

  • 在男子项目中，运动员平均体重最大的项目是拔河，平均体重达到96kg（拔河自第七届奥运会后已取消）；

  • 运动员平均年龄最大的项目是Art competition（自行百度这奇怪的项目），平均年龄46岁，除此之外便是马术和射击，男子平均年龄分别为34.4岁和34.2岁，女子平均年龄34.22岁和29.12s岁；

被单个国家统治的奥运会项目

很多运动长期以来一直是被某个国家统治，譬如我们熟知的中国🇨🇳的乒乓球，美国🇺🇸的篮球；

此次筛选了近5届奥运会（2000年悉尼奥运会之后）上累计产生10枚金牌以上且存在单个国家「夺金率」超过50%的项目；

  • 俄罗斯🇷🇺包揽了2000年以后花样游泳 & 艺术体操两个项目上所有的20枚金牌；

  • 中国🇨🇳在乒乓球项目上获得了2000年之后10枚金牌中的9枚，丢失金牌的一次是在04年雅典奥运会男单项目上；

  • 美国🇺🇸在篮球项目上同样获得了过去10枚金牌中的9枚，丢失金牌的一次同样在04年，男篮半决赛中输给了阿根廷，最终获得铜牌；

  • 跳水项目上，中国🇨🇳获得了过去40枚金牌中的31枚，梦之队名不虚传；

  • 射箭项目上，韩国🇰🇷获得了过去20枚金牌中的15枚；

  • 羽毛球项目上，中国🇨🇳获得了过去25枚金牌中的17枚；

  • 沙滩排球项目上，美国🇺🇸获得了过去10枚金牌中的5枚；
