Biomechanical study of badminton first appeared in 1984. In the article "Talking about the Best Force Structure of Killing Ball from Biomechanics", from the perspective of sports biomechanics, it is discussed in detail that the force process of badminton killing ball should be similar to whipping.
Theoretically, the key to improve the speed of whipping and killing the ball is to improve the angular velocity of each movement link in the swing process and the linear velocity of the racket face when hitting the ball, and to rationally use the braking method in the swing process. ?

Precautions for mass fitness:
Users should not rest immediately after fitness. After each exercise, we should adjust the breathing rhythm and properly carry out some low-calorie activities, such as walking slowly and taking a deep breath, so as to promote the blood of limbs to return to the heart.
Especially when you stop to rest immediately after strenuous exercise, the rhythmic contraction of muscles will stop, and a large amount of blood that originally flowed into muscles can't flow back to the heart through muscle contraction, resulting in a decrease in blood pressure, temporary cerebral ischemia, palpitation, shortness of breath, dizziness, pallor, and even shock and fainting.
It is not advisable to drink plenty of water after fitness. Don't drink water immediately after exercise, especially after strenuous exercise, and don't drink a lot of water, because drinking a lot of water will reduce the salt content in the blood, which is prone to muscle spasm and even cause headaches, vomiting and other diseases. Therefore, after exercise, even if you are thirsty again, don't drink water immediately, let alone drink too much water at a time. You should keep healthy by drinking less many times.
