Weight calculation formula: 2- 14 years old weight (kg) = (age× 2)+8kg height calculation formula: 1 year old height = (age× 5)+80cm According to this calculation, your sister is a little fat! Children lose weight differently from adults. While reducing fat, children should also ensure the physical and intellectual development, that is, the "reduction" and "addition" of the body. Therefore, children can't use hunger therapy: they can't use diet pills; You can't use weight-loss surgery and inappropriate fast weight loss. It can be seen that exercise is the most suitable for children to lose weight. Exercise to lose weight should adopt light physical activity, that is, appropriate endurance exercise, with the principle of increasing human aerobic metabolism. Emphasis on family characteristics, easy to implement and adhere to. It takes a long time to lose weight, starting from half an hour every day and gradually increasing to 1 hour every day. Exercise is scheduled for half an hour after meals, preferably every day, at least not less than 5 times a week. After each exercise, the body can see slight sweat, but it is more suitable for inadvertently skipping the speed and feeling overworked. There are many forms of weight loss exercise. Here are two simple and effective exercise methods. Walking is also a kind of exercise, but due to insufficient exercise, it can't meet the requirements of losing weight and fitness. It is measured that walking the same distance consumes twice as much energy as walking. 1. Time and distance: leave for half an hour every day and walk 3 kilometers; 40 minutes in the second week, 4 kilometers on foot; 50 minutes in the third week, 5 kilometers on foot; The fourth week 1 hour, 6 kilometers on foot, long-term persistence. /kloc-children under 0/0 walk for 40 minutes and 4 kilometers every day; 10- 13-year-old children finally walk 50 minutes and 5 kilometers every day. 2. Speed: In principle, it is every 10 minute 1 km, which can be slowed down at first, and then gradually meet the requirements. The distance and speed of walking can be mastered by the heart rate after exercise. Generally, the heart rate should not exceed 150% at rest. 3. posture: take a bigger step. Children and/kloc-adults over 0/3 years old should take no less than 70cm each step. Raise your head slightly, lean forward slightly, and relax your shoulders; Try to swing your arms forward and upward, breathe evenly and concentrate; When stepping, the center of gravity should be shifted from heel to toe, and it should be vigorous and powerful. Climbing stairs consumes more energy, because in addition to exercise, you have to overcome your own gravity. For example, climbing the 10 floor is equivalent to lifting the weight of 100 kg by 30 meters, which is quite expensive. According to measurement, going up and down stairs consumes five times as much energy as walking and twice as much as swimming. Five times. Climb the stairs for half an hour at a time, 1-2 times a day. We should start with a small amount of exercise and gradually meet the requirements. The ideal climbing speed is 30-50 steps per minute. Climb 10 minute, rest for 5 minutes. After exercise, the heart rate should be below 140 beats/min, and10-130 beats/min is more appropriate. Obese people have poor sports coordination ability, so pay attention to safety. Focus on exercise, keep your eyes on the front, lift your feet neatly, and stand firm, accurately and slowly.
