1. Sport stimulates the IQ

Keep in mind that children who go to school on foot, concentrate better and get better results. And this truth is also true for the elderly: those that provide some light physical effort and daily have a better memory.

Exercise brings more oxygen to the brain so that it is better protected against decline and dementia.

2. Music during physical training

Not only the music has a stimulating effect, but in addition it influences the number of steps we do. Urges a rapid pace to make more steps.

3. Are cramps due to a lack of salt?

There is no evidence that eating more salt, plenty to drink or eat bananas to help avoid cramping. The real causes cramping remain mysterious, but it is no at least not from a lack of salt. British nutritionist Ron Maughan, accompanying the Olympic athletes, found in various studies as sweat contains less salt than blood, people who sweat a lot lose more fluid, increasing the concentration of salt. If the latter was responsible for cramps, this should lead to their decline. This is not the case …

Dehydration is also not involved. No study proves that cramps are most common in athletes who lose lots of water sports than in the optimal moisture level. On the contrary, even, to some extent (5, 6). The heat is not involved either: cramps can also occur in very cold weather

According to Martin Schwellnus (University of Cape Town), cramps simply result from excessive forces.. The muscles contain small sensory structures: muscle spindles – which come into action when a muscle may be too stretched – and Golgi tendon organs that protect against exaggerated muscle tension. In case of fatigue, especially the latter declare package. It is then stretch the muscle to restore and relax the muscle. Fatigue seems to be the cause cramping, and you can not do anything.

4. Depressive disorders

In September 2014, neuroscientists Jorge Ruas and Mia Lindskog at the Karolinska Institute in Stockholm have published the sensational results of a study on exercise and depression. In case of mild and moderate depression, moderate and heavy exercise is as effective as antidepressants and psychotherapy.

At first glance, regular exercise does not achieve better results than antidepressants, but in light of the growing consumption of these drugs, side effects and costs rising, sport indeed constitutes an alternative.

However, exercise is very effective provided it is sufficiently intense. According to the latest recommendations, we must move 150 minutes per week of moderate or 75 minutes intensively. This training can be divided into blocks of 10 minutes minimum.

5. The body consumes fat permanently.

Many think to do sports for at least 30-40 minutes to burn fat. Yet our body is constantly consume, even at rest.

But the body handles sugars economically much more than fat because the reserves of the latter are much higher.

When one practices a sport quietly, muscles consume much more fat than sugar. Gradually, as the exercise intensifies, the consumption of sugar increases well as fat burning, but in smaller proportion. To burn more fat, you have to train regularly. More effort is provided, more energy is consumed and the body will seek the easiest source to use: fat. Well-trained athletes burn so much fat that sports less well trained or not. However, novice athletes consume more fat when they practice their sport calmly, about half their maximum capacity (or their maximum heart rate). What is interesting is that we can maintain this level of effort for much longer.

Warning! If you consume sugars or carbohydrates before or during sport, priority will consume the body, temporarily reducing the burning of fat. A good reason therefore to use sports drinks sparingly if you want to lose weight. It is better to drink water. (BBC / Bodytalk / AVE)
