Swimming can thin legs.
Swimming is a good aerobic exercise. When swimming, people's metabolism is very fast, and they can consume 1 100 kilojoules of heat in 30 minutes. At the same time, the thermal conductivity of water is 24 times higher than that of air, and the water temperature is generally lower than that of air, which is also conducive to heat dissipation and heat consumption. Therefore, swimming consumes much more energy than running and other land sports, especially slimming.
In addition, the buoyancy, resistance and pressure of water is an excellent massage for human body, which can play a role in beauty.
Extended data:
(1) Swimming suit:
Breaststroke+freestyle-slimming parts: thighs, arms and hips.
Butterfly+backstroke-slimming parts: waist, abdomen and back.
(2) Benefits of swimming: improving cardiovascular system, increasing vital capacity, improving respiratory system function, improving muscle system capacity, improving body temperature regulation mechanism, strengthening skin blood circulation, enhancing resistance, losing weight, strengthening physical fitness, enhancing adaptability to temperature and raising body temperature.
Different strokes exercise different parts: Although swimming is a whole-body exercise, different strokes exercise different parts of the body.
(1) breaststroke (thin thigh)-leg strength. The thigh style of freestyle and backstroke is whipping up and down, and only breaststroke is pedaling. The former can make legs longer, while the latter uses quadriceps more, so it is very effective for strengthening leg strength.
(2) Butterfly stroke (thin waist and abdomen)-chest strength. In butterfly stroke, the arm strokes inward, which is similar to chest expansion. Exert more force on pectoralis major, extensor dorsi and rectus abdominis, and the exercise effect is also the best.
(3) freestyle (thin arm)-arm strength. In freestyle, the biceps brachii and triceps brachii of the upper arm exert more force, which can effectively exercise the arm muscles and improve the shoulder muscle strength.
(4) Backstroke (thin buttocks)-back strength. When backstroke, the extensor 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.
