Alone, with milk or cappuccino: a 2017 survey ensures that 62% of the world’s population takes at least one coffee drink every 2-3 days. Many people drink coffee before exercising because it is said to help give a chute of energy naturally. But is this true?
How caffeine works
Caffeine is what gives strength to coffee. This substance stimulates the nervous system: it increases the production of noradrenaline in the brain and thus has an effect that enhances and stimulates performance. Sometimes, this is just what you need after a night of little rest or to overcome the drowsiness after eating. The coffee reaches its maximum effect 30 minutes after having consumed it.. This is a negative thing for people suffering from hypertension, since caffeine causes the heart to beat faster and blood vessels to dilate. Sometimes people feel palpitations if the coffee is very strong. But if your tension is in a normal range, this drink can also have benefits for the heart.
- Caffeine dilates the bronchi in the lungs. This means that it relaxes the muscles of the bronchial tubes and facilitates breathing.
- Do you usually go to the bathroom after drinking coffee? Caffeine stimulates kidney functions. With more leaks, the kidneys produce more urine.
- Caffeine, acids, tannins and coffee bitterness stimulate peristalsis (muscle contractions in the intestinal muscles that cause bowel movements). If consumed on an empty stomach, coffee can relax the intestines.
- It is also said that caffeine has an analgesic effect. It is used in some medicines as an auxiliary analgesic (for example in headaches).
Does coffee help you have more energy?
Coffee alone is a popular natural stimulant among fitness enthusiasts. A study published in the International Journal of Sport Nutrition and Exercise Metabolism investigated the effects of coffee consumption before endurance training (running and cycling). Significant improvements in performance levels were found in 5 out of 9 studies. In addition, it is said that caffeine reduces the perception of effort and facilitates breathing. A single coffee with 3 – 8.1 mg of caffeine per kg of body weight can therefore help you improve performance before training . However, there is no evidence that caffeine has a positive effect on muscle strength.
