battement tendu的训练目的与意义：是芭蕾基训中所有动作训练的基础与延伸，正确地学习与掌握它的规范性做法，可以为其他动作的学习打下良好的基础。battement tendu主要训练脚趾、脚掌、脚弓、脚腕、跟腱等部位的关节、韧带、肌肉等的柔韧性、灵活性和能力，同时锻炼人体的垂直站立、稳定性、后背的控制能等，使腿部的肌肉群得到延伸与外开的锻炼。
Battement tendu's training purpose and significance: it is the basis and extension of all movement training in ballet basic training. Correctly learning and mastering its normative practices can lay a good foundation for the learning of other movements. Battement tendu mainly trains the flexibility, flexibility and ability of joints, ligaments and muscles of toes, soles, arches, wrists and Achilles tendons. At the same time, it exercises the vertical standing, stability and back control of the human body, so as to extend and open the muscles of the legs.
battement tendu的要求：动作过程中人体垂直站立，身体的重量平均分配在双脚上，当动力脚向外擦出时，身体的中心微微移至主力腿。动力腿伸直，保持外开的形态，脚掌紧贴地面向外擦出，脚跟先离开地面，然后脚弓、脚掌一次离开地面，最后脚尖点地，脚尖向外擦出的距离是在两跨保持稳定、水平、不移动位置的情况下所能达到的最远点。动力脚向主力腿收回的路线与过程按照出时各部位的运动顺序依次反过来进行，脚收回至动作开始之前的位置。
Battement tendu's requirements: during the movement, the human body stands vertically, and the weight of the body is evenly distributed on both feet. When the power foot is rubbed out, the center of the body moves slightly to the main leg. The power leg shall be straight and keep the outward opening shape. The soles of the feet shall be close to the ground and rub outward. The heels shall leave the ground first, then the arches and soles of the feet shall leave the ground at one time, and finally the toes shall touch the ground. The distance of the toes rubbing outward is the farthest point that can be reached when the two spans remain stable, horizontal and do not move. The route and process of the power foot retracting to the main leg are carried out in reverse according to the movement sequence of each part at the time of exit, and the foot retracts to the position before the start of the action.
向前做时：脚跟先行，将脚尖留住，保持脚与腿部的外开形态，擦出至正前方的最远点，这时动力脚尖与主力脚跟最外侧呈垂直线；收回时脚尖先行，脚跟留住，将脚收回至动作前的位置。
When moving forward: keep the heel first, keep the toe, keep the outward opening shape of the foot and leg, and wipe it to the farthest point in front. At this time, the power toe is perpendicular to the outermost side of the main heel; When retracting, put your toes first, keep your heels, and retract your feet to the position before the action.
向旁做时：脚跟向前顶，保持脚与腿部的外开，擦出至正旁的最远点，这时动力脚和主力脚在平行的“一字”线上；再按原路线将脚收回至动作前的位置。    向后做时：脚尖先行，将脚跟留住，保持脚与腿部的外开，擦出至正后方的最远点，这时动力脚尖与主力脚跟最外侧成垂直线；收回时脚跟先行，脚尖留住，将脚收回至动作之前的位置。
When doing sideways: push the heel forward, keep the foot and leg open, and wipe it to the farthest point of the right side. At this time, the power foot and the main foot are on the parallel "line"; Then retract the foot to the position before the action according to the original route. When doing backward: keep the toes first, keep the heels, keep the feet and legs open, and wipe them to the farthest point directly behind. At this time, the power toes form a vertical line with the outermost side of the main heel; When retracting, the heel should go first, the toe should stay, and the foot should be retracted to the position before the action.
