Everyone has drunk sports drinks. Drinking sports drinks for fitness looks very good, but the truth is often not so beautiful!
Basically, most sports drinks are sweeter. What is the sweetness? In fact, you have already guessed it, it is carbohydrates. One of the functions of sports drinks is to replenish body energy, so carbohydrates are indispensable in the ingredient list of drinks. If you are more concerned about carbohydrate intake, the carbohydrate content of this sports drink naturally cannot be underestimated.
Let’s take a closer look at sports drinks. So what does a bottle of sports drinks contain? Carbohydrates, water, and vitamins will all be present. Generally speaking, the current capacity of a bottle of sports drinks is about 500ml. Take XX brand sports drinks for example, its capacity is 600ml. See the figure below for the specific nutrient composition. Simple mathematics can be converted into a calorie of 88 * 6 = 528KJ.
Assuming that we exercise for one hour, let’s try to calculate how many calories we consume in one hour of fitness exercise. There are not many data on direct calorie expenditure in strength training, or it is because the related factors are too complicated. The direct calorie consumption of strength training is generally not very high, and it is generally lower than that of moderate and low-intensity aerobic exercises at the same time. For example, in the following data, “Strong bodybuilding”, METs is only about 6. 6METs is equivalent to 6 kilocalories per kilogram of body weight per hour. For example, a person weighing 70 kilograms, who exercises heavily for bodybuilding, consumes about 420 kilocalories per hour.
An ordinary person weighing 70KG consumes 420 kilocalories per hour of fitness, which is 420 * 4.184=1757.28KJ, 528/1757.28=0.3, which means that a bottle of XX sports drink is relative to the calories consumed for 20 minutes of fitness. If you work out for only half an hour on weekdays, a bottle of sports drink will basically recover your calorie consumption, which is really not worth it!
If you don’t have precise control over your usual food calories for fitness, you obviously have not counted the calories of an extra bottle of sports drink. So bodybuilders still drink boiled water or mineral water. After all, the “energy” of sports drinks is a bit high, and it absorbs a lot of energy unknowingly, sin!
