What muscles can backstroke exercise?
The latissimus dorsi and gluteus maximus are the main muscles, and the muscles on the limbs can be exercised.
When backstroke, latissimus dorsi will exert more force and stretch the back muscles. In addition, when backstroke, you need to lift your hips and slide, which is also an exercise for your hips. When backstroke, the buttocks are basically in a state of tension all the time, and there is no pressure on the development of the small buttocks. Coupled with the beautiful back, it can definitely kill passers-by.
What part of the muscle does backstroke practice?
When backstroke, latissimus dorsi exerts more force, which can relax the back muscles and help relieve the discomfort of backache. In addition, backstroke also needs the strength of the buttocks, so it also plays an exercise role in the muscles of the buttocks. In addition, when the body turns to both sides in backstroke, it can not only reduce the resistance, but also exert the strength of the large muscle groups of the body, which also has a certain effect on eliminating excess fat in the abdomen.
When swimming, the greater the resistance of water, the greater the stimulation to the cerebral cortex, so as to reflexively adjust the movement of more muscle groups, so that the whole body muscles, especially the pectoralis major, deltoid, triceps brachii and back muscles, can be exercised in an orderly manner, and a uniform muscle group can be shaped.
Backstroke technique
1 When kicking, be careful not to kick too deep. If you kick too deep, your body will float upwards and your speed will slow down.
When you stop, if your shoulder sinks into the water, your hand will come out of the water before your shoulder and your shoulder will sink. Shoulders and upper arms will be held down by water. You should stretch your elbow with the rotation of your body.
When backstroke, the waist muscles should be kept moderately tense, and the body should not sleep too much on the water or sit down. Lift your ribs, not your chest.
Matters needing attention in backstroke
First of all, you must not be afraid. Before studying, you'd better lie on the water while pulling the rope in the swimming pool, which can exercise your courage.
Second, the most important thing in backstroke is the coordination of arm and foot swing. When the hand strokes backward, the foot does not move, and when the foot moves, the arm comes back.
Third, some people may think that the greater the intensity, the better, but in fact, it is good to follow the normal intensity. Too much force will increase resistance. Make your swimming speed slower.
