Jazz dance, like modern dance and ballet, is a very severe physical test, which makes warm-up preparation before practice extremely important. Warming up can also benefit jazz dancers both mentally and physically. From a physiological standpoint, the effects of warm-up exercises include: increasing the speed and strength of muscle contraction, improving muscle coordination, and preventing or reducing injuries to muscles, tendons and ligaments; especially for jazz dancers, the back and chest , abdomen and other parts are also used quite frequently, so you should pay more attention when doing warm-up exercises. Psychologically, it can prepare learners to start exercising and cultivate their emotions, allowing students to be more focused and feel motivated to learn.

The warm-up movements of jazz dance are very rhythmic and usually last 20-30 minutes. Since jazz dance classes involve tiptoeing, fast kicking, spinning, jumping, sustained or rapid contraction of the abdomen, etc., ballet squats (plié) and stand-up movements (relevés) are often added to the warm-up exercises to help. It prepares the muscles of the feet and legs. In addition, it requires independent and joint movements of the upper body limbs and trunk to achieve the effect of whole body warmth and muscle flexibility.

If analyzed from the perspective of physical fitness elements, relevant considerations for jazz dance include:

Cardiorespiratory endurance – Generally, a combination of jazz dance movements does not last very long, but The rest time between combinations is often very short, so if the learner has good cardiorespiratory endurance, he or she can generally maintain good dance skills after repeated combinations of movements and avoid premature fatigue.

Muscle strength and muscular endurance – There are many fast and instant force movements in jazz dance, so basic muscle strength is necessary. In addition, because when learning dance, you often need to practice the same movement multiple times, the requirements for muscle endurance are relatively high. In particular, the endurance of the lower limb muscles must be trained well, otherwise it will easily cause injuries to the knee, ankle, hip joints and nearby muscles. Jazz dancers also use other auxiliary exercise methods (such as water fitness, yoga training, etc.) to enhance muscle endurance.

Softness – No matter what kind of dance, if you want to dance beautifully, the flexibility of your body must be good, otherwise you will not be able to show the beauty of your lines, and jazz dance is no exception. When performing warm-up stretching exercises, you must be careful. It is not appropriate to use elastic vibration to stretch before the muscles of the body are completely warmed. Otherwise, it is easy to backfire and strain the muscles. Static stretching is safer, but requires more patience. The range of softness exercises should not reach the point of pain. It is enough for the muscles to feel tight. The duration of the movements (angles) can range from 10 seconds to 30-40 seconds. The longer the time, the more harmful it will be to the muscles and joints. The load on nearby connecting tissues is also higher.

Body composition – Most great jazz dancers have strong muscles, but generally have less body fat. This makes their bodies show obvious muscle stripes, making their movements more powerful and powerful when dancing. The lower fat content also prevents dancers from carrying unnecessary weight, making dance movements more graceful and light. Although learning jazz dance can also be a way to lose weight, beginners who are overweight should first lose weight through other methods, otherwise it will pose a certain risk to the health of muscles and joints.

Coordination – Coordination is very important in jazz dance. In addition to the coordination of hands and feet, there is also the coordination of movements of the head, trunk and limbs. In addition, in jazz dance, different parts of the body will dance at different rhythms at the same time, which is really a big test for the dancer's coordination ability. When you first learn, it is appropriate to practice the movements of different parts of the body separately, and then continue to coordinate them into the required movements. That way you will have a higher sense of success.

Dexterity – Jazz dance often uses movements in different directions and levels to increase excitement and entertainment. Therefore, dancers must be dexterous and skillful in their movements, and their angles must be accurate and quick when turning.

Balance – The ability of dynamic balance is often more widely used in jazz dance than static balance. This means that dancers must be clear about the shift of the center of gravity of the dance steps, and they must skillfully use their eyes. To help position yourself and help you balance when turning.
