The Forearm Muscles Power To Raise University Students Tennis Training A Spin Quality Research

Tennis serve is the only own hands without hitting the other control method is best tennis player of today's powerful weapon to defeat the enemy. Thus, athletes may serve a strong and accurate by ferocious tricky catch each other's difficulties caused by the impact point, thus winning their access to each other's advantage. In the first tee, the player with swift and strong flat hit ball directly to score in the second serve, the player is often tricky with the rotation of ball impact point caused by difficulties in the other catch. Fast, fierce flat hit ball in the game can often score directly, but the success rate is low,Thus restricting the athletes in the bold use of race. Cutting off the tee and the right side of the upper-right spin serve in practice, spend more, especially the latter when serving in the second athlete has been widely adopted. Second ball through a high success rate, tricky impact point, a strong rotation has become offensive to the other start.In the spin serve, a strong arm and wrist pronation and external rotation, flexion and extension, its main role is to make the ball produced a strong rotation, which is a basic part of ball rotation. In order to improve the success rate of driving and scoring rate, we must increase the ball's rotation and impact point of the change, which should increase your tee time at the wrist action.Tennis Options in college teaching of teachers are often only emphasizes the teaching of technology, but have neglected the special quality of the training, and the special quality of the training process in the absence of specific, more scientific; training means a single, training load, training cycle, setting unreasonable. Based on the above understanding, research and explore the students in our hospital forearm muscle speed and strength training, a combination of teaching methods and technology has important theoretical and practical significance.The research focus adopted in the literature and data, survey method, teaching experiment, as well as mathematical statistics and so on, the students in our hospital Tennis forearm muscle speed and strength training means and methods were studied. Reached the following conclusions:1. Through investigation and research, as well as the relevant body of scientific theories, this paper presents the forearm muscle speed and strength training in five indicators: X120 second straight arm wrist flexion and extension load time (3-5 kg), X220 second straight arm wrist circling load time ( 3-5 kg), X320 second straight arm wrist adduction outreach loading time (3-5 kg), 4120 second straight arm wrist pronation and external rotation load time (3-5 kg), X510 sub-grip grip loose timing.2. Forearm muscle speed and strength training arrangements. One class of training time should be controlled within 30 minutes, best to keep the anaerobic state, namely the duration of each exercise less than 10 seconds, and practice strong limit should be used or sub-limit, rest periods between each cycle should be controlled at 4 - 5 minutes between the number of weekly exercise is 2 - 3 times.3. Emphasis on technology in teaching and made the ball spin rate of forearm muscle strength training combined. Forearm muscle speed and strength training can serve to improve the success rate of rotation and increase the spin of the ball. The experimental group of students serve success rate of rotation of the spin and the ball has significantly improved.Through the experimental results showed that forearm muscle speed and strength training methods and techniques of teaching organic combination, enabling students to better grasp the hair spinning ball technology to improve teaching effectiveness, college tennis at the same time want to be able to provide some theoretical reference for technology teaching.
