Vitamins, minerals, etc. Vitamin drinks can quickly supplement human nutrition and relieve fatigue after exercise, but the improvement of physical fitness test results should focus more on ordinary exercise. Caffeine in functional drinks can refresh people who often stay up late, but drinking functional drinks should not be addictive, so be sure to drink it in moderation. In addition, you can also choose tea and freshly ground coffee to refresh yourself.

Sports drinks, the secret of scientific research, must contain some sugar. If soft candy, glucose and glucose are used as raw materials, the sugar concentration of 6% is generally selected, which is the best concentration to accelerate blood rehabilitation treatment and show kinetic energy. Any sugar concentration higher than 6% may slow down digestion and absorption, leading to beverage retention and digestive tract. This is why drinks with sugar content above 8% (such as juice and carbonated drinks) are not suitable for exercise. At present, the best sports drinks are mainly xylooligosaccharides. The molecular structure of xylooligosaccharide is 3~ 10 times larger than that of glucose and 1~5 times larger than that of sugar. Its advantages include providing more kinetic energy, low sugar, non-stick to mouth and throat, etc. , is conducive to filling blood sugar levels, so that people's brains and muscles continue to digest and absorb sugar during fitness exercise, thereby developing physical strength, delaying fatigue and accelerating rehabilitation after exercise.
