Playing a sport is a great way for adults and kids alike to get into shape and have a great time. While sports are a great way to exercise, it's important to remember that any type of physical activity can pose at least some level of risk. By having a sports first aid kit you can make sure that you are prepared in the event that something unfortunate happens. In most cases most sports injuries are minor such as a sprained ankle or knee.
However it's important to plan for more serious injuries so that you can be prepared in the event that one occurs. While it's not common it's certainly possible that someone can suffer a broken bone, a blow to the head, or even cardiac issues while playing a sport. Although these are certainly worst case scenarios, having a plan on how to handle them in the event that they arise is important.
A sports first aid kit should contain a cold pack, bandages, ace bandages, and some kind of antiseptic. These are the basics that will allow you to either treat a minor injury, or help to deal with a more severe one en route to a proper medical facility. Although your capability to treat serious injuries may be limited, doing the best that you can in the situation is certainly better than doing nothing.
In the event of a broken ankle an ice pack can provide some level of relief while on the way to a hospital. If someone is seriously cut, having bandages on hand can help to stem the flow of bleeding while waiting for medical help. Of course in the case of any serious injury an ambulance should be called, but by having a sports first aid kit you can provide basic treatment while waiting for medical professionals.
