What are some technology changes in Tennis and Archery?
With tennis it is the racket mostly, and material for the string.



Here's a list of inventions that have changed archery.



1. Invention of bow sight, now comes in many shape, pin sights, open ring sight, scoped sights etc.

2. The invention of the Aluminum riser, this allows the bow to be fitted with stabilizers, sights and all sorts of add ons.

3. The invention of the compound bow, these are bows with wheels to make holding the bow at full draw a lot easier, it uses pulleys to allow the archer to only hold a fraction of the bow weight at full draw. The pulleys also make the force of the bow when released much greater than conventional bows.

4. Mechanical release, was originally invented for use on conventional recurve bows but are now illegal in competitions and only legal for compound bows.

5. Bow limbs have now moved from wood to carbon fiber and foam base or carbon fiber with wood core. Plain wood limbs are still in use but mainly for traditional bows or beginner equipments.

6. Arrows, have gone from wood to aluminum, then to the top of the line carbon shafts with tungsten points.

7. The fletching on arrows have gone from feathers, which is still being used, to mylar for long distance arrows.

8. String material, have also evolved, it went from linen at one point to nylon, kevlar, dacron, and now we're using dyneema and other variations of hmpe fibers.



Given all the advancements in archery though, the most amazing shots I've ever seen are from this fellow named Byron Ferguson, using a wooden longbow with wood arrows and feathers. What the technology does is, it allows mediocre archers like myself to compete, for the real champions the advanced equipments will probably buy them 1 or 2 points out of 1440 point. Rick McKinney, shot a 1352 out of 1440 way back when with aluminum riser, aluminum arrows and wood limbs, yet in this day and age, with all the carbon equipment, there are very few archer out there that can shoot that score.

I would think the tech change in tennis that most affected the game was the change from wood racquets to metal and then from metal to graphite and now to all kinds of space age material. Same goes for archery...wood to space age materials now.
