Jazz dance warm-ups are rhythmic and usually last 20 -- 30 minutes. Because jazz dance classes involve tiptoeing, rapid kicking, spinning, skipping, and sustained or rapid abdominal contractions, ballet squats and relevés are often added to the warm-up to help prepare the feet and legs, and independent and combined movements of the upper body trunk are needed to achieve the effect of whole-body warmth and muscular flexibility.
If analyzed from the point of view of physical fitness elements, the relevant considerations for jazz dance include:
Cardiorespiratory endurance - generally a combination of jazz dance movements is not a very long time, but combinations and combinations of rest time between the combination is often very short, so if the learner's cardiorespiratory endurance is better, generally in many repeated combinations of movements after the movement is still maintained well, and not too early. The dance technique does not cause premature fatigue.
Muscle strength and endurance - In jazz, there are a lot of fast and instantaneous movements, so basic muscle strength is necessary. In addition, because learning to dance often requires practicing the same movement over and over again, the demand for muscular endurance is relatively high. In particular, the endurance of the muscles of the lower limbs must be well-trained, or else it will easily lead to injuries to the knee, ankle and hip joints and the nearby muscles. Jazz dancers also use other complementary exercise methods (such as water fitness, yoga training, etc.) to enhance muscle endurance.
Flexibility - No matter what kind of dance you do, if you want to dance beautifully, your body must be flexible, or else you won't be able to realize the beauty of your lines, and jazz dance is no exception. In the warm-up stretching movement, we must pay attention to the fact that it is not suitable to use the form of elastic vibration to stretch before the body muscles are fully warmed up, otherwise it is easy to make a mistake and strain the muscles. Static stretching is safer, but requires more patience. The amplitude of the flexibility exercise should not reach the point of pain, muscle tension can be felt, the action (angle) can be maintained from more than 10 seconds to 30-40 seconds, the longer the time on the muscles and joints near the connective tissue of the load is also higher.
Body composition - Most good jazz dancers have strong muscles, but generally have less body fat. This gives their bodies a distinct muscular striation, which makes their movements more powerful and dynamic. Lower body fat also prevents dancers from carrying unnecessary weight, making their dance moves more graceful and light. Although learning jazz dance can be a way to lose weight, beginners who are overweight are advised to shed pounds through other modes first, otherwise there is a certain risk to the health of muscles and joints.
Coordination - Coordination is very important in Jazz Dance, not only the coordination of hands and feet, but also the coordination of head, torso and limbs. In jazz dance, different parts of the body move at different rhythms at the same time, which is a big test for the dancer's coordination ability. It's a good idea to practice the different parts of your body separately, and then continue to work on them together to create the desired movement, so that you will have a higher sense of success.
Dexterity - Jazz dancers often use different directions and levels of movement to increase excitement and entertainment, so dancers must be dexterous in their movements, and the angle of their turns must be accurate and quick.
Balance - Dynamic balance is often more widely used in jazz than static balance, which means that dancers must have a clear sense of how to shift the center of gravity of the steps, and must be able to position themselves with the help of their eyes to assist in balancing when turning.
