personally i use a mercian stick (and love it) , but Dita and grays are really good also :)
It is a third class lever.
A hockey stick is required either way, but the type will affect whether you use a ball on a field or a puck on some ice.
You use a stick in the sports of ice hockey and lacrosse.
Yes, there is a lot of research out there. Just go on Google and type in "Field Hockey".
No. Originally "field hockey" was not called that, as at the time of origin there was only one type of hockey with variations, played around the world. Outside of America and Canada field hockey is known by its original and formal name of hockey. It is only after the popular growth of ice hockey and roller hockey in North America that the word "field" was added to distinguish it.
Ice hockey, field hockey, etc. Just about any type of hockey you can think of, I guess.
I will tell you the ones i know of. Mini hockey is only played in a half of a hockey field, or even smaller, and there are 8 that play. Field hockey is played full field (the whole hockey field) and you have 11 players that play (including the goalkeeper). They are both similar in that they both play with hockey sticks and they are still a type of hockey. The same rules apply in both.
I believe the first kind of hockey was played on feet, not skates, it was called shinny. They played with some type of wooden block (similar to a puck), or some type of ball. An unlimited amount of people played. The oldest type of hockey is field hockey. There is an ancient Greek frieze depicting two field hockey players at Olympia, Greece.
It depends on the type of hockey. For field hockey, it is the International Hockey Federation (FIH). For ice hockey, it is the International Ice Hockey Federation (IIHF)
