An interesting study was conducted by a team of scientists from South Australia. They found that today's children run slower than their parents at the same age. The research team was interested in, what is the reason for such temporary changes.
The study was conducted under the supervision of Professor Grant Tomkinson, who analyzed the indicators of physical development of children from 1964 to 2010. The analysis was subjected to information received from more than 25 million children in 28 countries. Most scholars interested in the performance when running load.
The study showed that every ten years the measure of the endurance of children is declining on average by five percent. The current generation runs a mile in 90 seconds slower than children, information from which was obtained thirty years ago.
The primary factor that influenced the decrease in physical form, has become overweight. The children of today, scientists say, less exercise. They spend more time in a static position, preferring the computer and the Internet walks in the fresh air.
It should be noted that these studies truthful regarding European countries, Australia and New Zealand. However, the endurance of children and adolescents in Japan remained at a decent level and not decreased over the last thirty years.
