Globally soccer causes more such injury than either of these. For some of these activities, some decent measure of protection is available in the form of well-designed helmets. Such materials are not practical for football or ice hockey helmets, where multiple blows to the head are experienced in every game. One cannot change one's helmet after every play. Having said that, better designs are appearing on the market, particularly for ice hockey.
Some players complain of the expense of a good helmet.
Even good helmets must be worn and fit well in order to work. I suppose it might protect the rear wheel a little in a collision. A helmet should fit tightly enough that the chin strap is an afterthought and not what keeps the helmet on the head. This has been the case in both tackle football and ice hockey. As a result the incidence of death and catastrophic neck injuries plummeted and the incidence of head injury improved somewhat.
