A few years ago when I was competiting in the heavy events at the Scottish Highland Games, the trig was a straight piece of timber... maybe 6 X 6 inches and 4 feet long.
The trig was placed at the front of a 4 X 10 foot "box" marked on the ground. When throwing the 56 pound weight for distance, the 28 pound weight for distance, the stone or the 22 pound hammer, the competitor used the area inside the box to build up speed for the throw. The movement, except when throwing the hammer, was usually from the back of the box toward the front. During the throw, the competitor's foot could touch the trig, but if he/she stepped ON TOP of the trig, the throw was disqualified. Stepping over the trig also disqualified the throw.
And in the dim past when I was a track and field athlete in high school, we always called the curved board at the front of the shot / discus circle the "trig" IIRC.
If I could figure out how to do so, I'd insert a pic of me twirling round just about ready to fling the 28 pound weight. It would be good for a laugh. I'm sure my kilt would thrill you all no end. Of course, no kilt, ya can't play!!
