Matters needing attention
One: Normative action
The standardization of movements is based on the standardization of movements, so the position, direction and movement route of limbs must be accurate when practicing. Pay attention to the speed, muscle strength and amplitude of the action, that is to say, the muscles are fully elongated and contracted, so as to achieve the overall effect of the action.
Second, the flexibility of action.
Elastic movement is one of the characteristics of aerobics, and the elasticity of movement involves many parts of the body. Therefore, attention should be paid to the control of muscle contraction and relaxation during practice, so that the movements are elastic and the rhythm is even, and the joints are prevented from being excessively stiff and overstretched.
Three: the sense of rhythm of action
Mastering the rhythm of movements is very important for aerobics practice. Practitioners must have certain muscle control ability, music rhythm and action completion ability if they want to perform better movements. Therefore, in practice, we should pay attention to the development and training of students' sense of rhythm, so that students can master the sense of rhythm slowly on the basis of understanding the rhythm of music.
