I assume by this you mean curveballs so these all the ways to throw different curveballs:
Curveball: Grip the ball like a two-seam and then put your fingers off-center so they're on the right seam, then snap your wrist hard off to the side. This can be very damagaing to your elbow if you're not mature enough and if you throw to many of them, can still be damaging even if you're old enough.
12-6 Curveball: Take the curveball grip and then move the ball up so your fingers are on the right seam of the horseshoe. PRESET your wrist in a position as if you're throwing a football. Then come straight down. This is much more safe than a curveball although with your fingers off-center you will probably come off very slightly. I would still not recommend throwing it if your not old enough but you can most definetly throw it with hardly any risk once you're old enough to.
Spike Curveball: Take a four-seam grip and then curl your fingers back so your fingertips are pressed hard into the ball. Then move your hand up so your about 3-4 of the way up from the bottom seam to the top and then throw straight down. It will have movement like a 12-6. Most pitchers have more success with a 12-6 but others have a better spike so you should definitley try it. This is completely safe to throw at ALL ages.
Knuckle Curveball: Position your index and middle knuckles so that they're on the bottom of the horeshoe seam and the thumb underneath. As you release flick your fingers forward. This will have curveball-like movement and is safe to throw at ALL ages. However, it could seriously mess up your form so be careful of that.

Track itself only has discrete roots back to the early 1800's in various countries in Europe, eventually making its way into America. Track events however, started back before there were even countries that one could classify. The Greek started holding Olympic Games including events such as the Standion Race (Running Race), the Long Jump, the Javelin Throw, the Discus throw, and wrestling. All of these (with the exception of Wrestling) are modern day track meet events. So to directly address your question:
Track and field began nearly 2700 years ago in the Greek Empire.
A Javelin is a spearlike shaft about 8 1 / 2 feet (2.7 meters) long and usually made of wood, used in throwing for distance. Commonly, the Javelin is used in the outdoor activity, Track.
