The history of man's involvement with water sports stretches back before history was written down. It is a history of the development of technology as well as human physical achievement. Man first took to water in boats that sailed around the world with nothing but the stars to guide them. The seas and rivers were a mystery to be feared, for lurked unknown creatures and death by drowning. Few actually ventured into the water. This changed as time went on. As a sport, however, water sports such as swimming, diving, and water polo are new comparatively to those on land. Probably the oldest one is rowing in a rowboat. This is seen in modern games such as competitions between rowing clubs in British and American universities. Olympic Water Sports began with swimming but did not end there. Olympic swimming began in the same year that the modern Olympic Games began in 1896. Yet, swimming as a sport can be traced at least back to the 16th century. The different kinds of water sports such as diving or water skiing came much later. Diving is especially important for China as many Chinese divers are the best in the world. Water games for fun are also a part of everyday life. If people live around water that they can swim or play in, these will be integrated into the culture. Many cultures have a tradition of water sports. While it is still an element that is dangerous and with which we wish to measure our courage, water is no longer a thing of mystery. It has become a medium through which we can enjoy our lives.

人类开始参与水上运动可以追溯到历史被记载之前。那是伴随着工业发展和人类体能进步的一段历史。人类第一次乘船环游世界的时候什么都没有带，只有星星为其指引方向。海洋和河流是令人生畏的谜，因为那里潜伏着不为人知的生物和被淹没而死亡的危险。很少有人敢真正地冒险下水。随着时间的推移，情况发生了变化。然而，作为一项运动，水上运动相对于陆地运动来说是新鲜的，例如游泳、跳水和水球。或许其中最古老的运动就是划船。这项运动在现代比赛中常可看到，例如英美校际俱乐部间的划船比赛。奥林匹克水上运动始于游泳但却不止于此。奥林匹克游泳运动始于现代奥林匹克开始的同一年，1896年。然而游泳作为一项竞技运动至少可以追溯到16世纪。不同种类的水上运动则出现得晚得多，例如跳水和滑水运动。跳水运动在中国占有重要地位，中国有很多跳水运动员都是世界的顶级选手。为了娱乐的水上运动也是人们日常生活的一个组成部分。如果人们住在水边，他们就可以去游泳或在水里嬉戏，这也会融入当地的文化中。许多文化都包含水上运动的传统。尽管它仍然是一个危险的因素，而我们却可以用它来衡量自己的勇气，况且水已经不再是一个神秘的事物。水已经成为一种媒介，通过它我们可以享受生活。
