In America, thousands of people go jogging in the sea or swimming pool, which is a new exercise to lose weight.
Jogging in water can distribute the body load evenly, which has obvious advantages over running on land. On land, each foot will hit the ground about 1000 times per mile, and the feet, knees and buttocks will vibrate, so they often sprain muscles or strain ligaments, while in water, the vibration of lower limbs is zero, so the above accidents will not happen. The resistance of water is 12 times that of air. Running in water for 45 minutes is equivalent to running on land for two hours.
Jogging in water is especially suitable for obese people. Because the density and heat transfer of water are greater than that of air, more energy is consumed in water than on land. The experiment shows that the heat released by staying in water at 12℃ for 4 minutes is equivalent to the heat released by staying on land at the same temperature 1 hour. Running on land 100 meters consumes about 35 kcal, and jogging in water 100 meters consumes 65 kcal. It can be seen that in the same time and intensity of exercise, water consumes much more energy than land, and these energy supplies are supplemented by consuming sugar and fat in the body. Through this method, we can gradually reduce the excess fat in the body, reduce the internal organs and make the body healthier.
