Today is Wednesday and I should be training... But I need to finish up some freelance job (from London) and that's why I'm sitting in front of the computer screen again...
There was this TV program last week - Sport Science. It was done by the same team who did Fight Science on Discovery. Remember the muscle man with a katana, who violently chops the human jelly to see how much damage a Japanese blade can make? ...Yeah that's the one.
At one time they wanted to test if weighted warm-up helps. So they gave donut-shape weights to a pro-baseball player (batter) to swing a couple of time before measuring his strikes with a normal bat, and also repeat similar test with a pro-golfer. While the swings "feel" faster to the player, the result didn't show much difference for the speed of the balls.
The most significant change was WHERE the point of impact was. Many strikes were out of the marked "sweet spot" when they rolled in slow motion. So after weighted warm-ups, players will miss where the optimal point they should hit the ball with. Essentially this means the weights are counter-productive... It changes the players sense of balance towards the "bat".
Because of the above, the baseball player receives the impact not just on the bat, but also all the way down to his hands and elbows (that was shown in slow motion for obvious reasons!). The swings are getting less flexible, and will possibly let the player develop "Tennis elbow" or other wrist injuries. I wonder if this is relevant to those who keep breaking their shinai... hmmm...
In the end, I'm trying make excuses of not doing any more ridiculous 2-shinai hayasuburi warm-up at the old squad training. I understand the muscle-building and cardio-training parts, but for warm-ups - better stay away...
