通过观察各种不同技术类型优秀球员的比赛录像、图片资料,以定性分析为主,对各个球员正拍底线击上旋球的技术特点和生物力学特征进行比较分析。认为现代鞭打式正拍击球技术比传统长行程击球技术有明显优势,可以击出力量更大、速度更快、旋转更强、极具穿透力的上旋球,显著提高了击球的攻击性和稳定性,应当在网球教学和训练中优先采用和推广。 By observing the competition video and picture materials of excellent players of different technical types, qualitative analysis is mainly conducted to compare and analyze the technical characteristics and biomechanical characteristics of each player playing the bottom-up spin ball. Considering that the modern whipping-type shot technique has obvious advantages over the traditional long-stroke technique and can hit a larger, faster, more rotating and highly penetrating spin ball, significantly improving the hitting The aggression and stability should be given priority to and promoted in tennis teaching and training.
