Do you think this lack of facilities and resources, could possibly be the reason they generate the top sprinters? I am currently training to run the 100m at the professional level and as of now I have just been running for the most part. Not much lifting other than a hang cleaning workout once a week nothing to heavy. But my coach includes plyos and power exercises on the track and grass as well as the typical things you do in a track and field practice. (SIDE NOTE- My coach is olympic medalist Antonio Mckay, google him)..but I have been improving daily and feel very explosive and fluid. I have been basically sticking to the track and grass. Prior to switching coaches I ran track at Texas tech, in which we lifted everyday of the week but wednesday. Most of the lifts were heavy, and when it came time to sprinting I was always stiff , and I had a non stop aching back and hamstring, that eventually led me to injury the first meet. I also never really felt explosive. Which was odd to me because I have always been known to be an explosive sprinter.
So my theory ?is, the fact that the Jamaicans lack the facilities could be the reason they are dominant in the sprints. They use more of the Earth to train, which has to be less wear and tear on the body. Unlike weights, which is constant strain on the body. And it makes sense to think that a recovered body is a more efficient body which means you will get more out of the training. Also the heavier you are the harder it is to move your body. Weights add weight, especially when sets start to get down to 4,3,2’s.
Let me know if my theory makes sense. Im all ears when it comes to a good discussion about track and field! haha
