Growth
Growth is the fundamental realm of children and young people. So much of their resources are used up in this activity it's surprising that there's any energy left for running around.
Children have different injury risks to adults and some times are more risky than others. There are times when growth is quicker and these times present greater challenges to the young body. If these times coincide to certain parts of a sporting season then the risks may add together.
Knowing when to push on or when to back off is part of the way we reduce risk of injury. As well as the young person themselves, Parents and Guardians are central in managing, supporting, explainiing and liaising with clubs and school.
