The first two throws innovations have been outlined previously:
It is quite difficult to follow the progression of the number 8 innovation. Although the exact timing of when throwers first began to be paid (either openly or ‘under the table’) is not easily determined, the inclusion of pay for performance has had a massive impact on the lives of track and field throwers.
Throwers typically do not receive the massive endorsements, which Usain Bolt or Sanya Richards-Ross may obtain, but most top throwers receive enough money in government funding and modest sponsorships to cover at least basic living expenses. The hope is that this financial aid allows the top athletes to focus almost entirely on training, allowing for maximum achievement of sports form while using clean training practices. Furthermore, up and coming athletes in most countries do receive some financial aid, meant to facilitate the growth of these young athletes and hopefully allow them to progress to a world class level.
I would argue that although the current level of funding is helpful, it could certainly be greater. A high percentage of top athletes still live under the poverty line, and many times must work part-time jobs on the side to cover expenses. This greatly handicaps their training and performance progression. Furthermore, the therapies needed to train at a high level (massage, physiotherapy and so on) are expensive, and are therefore often neglected by athletes. This neglect can lead to reduced throw distances, or even worse, injury. The payment of track and field throwers produced large changes in how athletes are able to train, but because payment is common to all sport today, this innovation only makes it to number 8 on this list.
