All imputs on this topic would be greatly appreciated- whether it be scientific studies on this topic or just your opinion, im interesting in hearing everyones different point of views. If you dont understand the question being asked i will explain it more
The benefits that a short sprinter (60m -100m) might derive from the weight room may be quite different from the benefits enjoyed by a longer sprinter (400m – 800m). I see your PRs listed are for the 400m and 800m. The cost/benefit ratio of additional muscle mass is higher, IMHO, for an 800m runner, than a 100m sprinter. You should keep that in mind when planning your weight program.
