帆板是一块略有流线型有浮力的平板,宽60公分,长不到4米,重不过20公斤,人体站立在板上直接用双手抓住帆杆来操纵,靠风力在水上滑行前进,时速可达几十公里。同时比赛在湖、海上进行,波浪起伏,潮水、风力及涌浪等因素的干扰较大,如果没有良好的平衡能力和高超的驾驶技术,是难以在风浪中行驶的。一、帆板运动的“平衡”是怎样形成的当帆受风之后而产生的帆力与人体为了保持桅帆的直立而施用的拉力之间大小相等方向相反的力,作用在一条直线上即形成帆板的平衡。但是帆板在行驶中这种人力与帆力之间的平衡经常被随时变化的外因所破坏。因为风速风向的变化会改变帆力的大小而波浪的起伏又会影响人力和帆力的稳定,这些都是破坏平衡的原因,
Windsurfer is a slightly streamlined buoyant plate, 60 cm wide, less than 4 meters long, weighing 20 kg, the human body standing on the board directly grasp the sail with both hands to manipulate, by the wind gliding on the water forward, speed Up to tens of kilometers. At the same time the competition in the lake, the sea, waves, tides, wind and surging and other factors more interference, without good balance and superb driving skills, is difficult to drive in the storm. First, the windsurfing “balance” is how to form when the sail after the wind and the human body in order to maintain the upright and maneuver to pull the force between the equal size in the opposite direction of the force acting in a straight line that Form a windsurfing balance. However, the balance between manpower and sail on a windsurfing board is often damaged by external factors that change at any time. Because changes in the wind speed and direction will change the size of the sails and the undulations of the waves will affect the stability of manpower and sailing power. All these are the reasons for undermining the balance,
