How does loco parentis affect sport?

Loco parentis is when someone is responsible for a child either because their biological parents are temporarily ill, on holiday or just at home while the child is at school or a sporting event. This brings me on to how does loco parentis affect sport? Well, if a person is under the age of 18 they are classed as a child and therefore must be in sight of a person over 18 years of age. This person will then be their loco parentis. In sport such as rugby the athletes up until the youth team are under 18 and so should require an adult at all times, someone who is responsible for them if they had an injury or were upset.
