Our athletes and followers are well aware by now of the dangers of long distance training (see Sparta Point 12/31/08). We define long distance training as any form of exercise lasting greater than 30 seconds, and it is the one of the best ways to lower your jump, decrease power, and produce overuse injuries (tendonitis, shin splints, etc.)
Yet, coaches and players continue to make exceptions. The baseball world calls it “flush runs”, jogging or running the day after pitching to clear the soreness from the day before. Soccer/rugby calls it “an aerobic base”, starting the offseason with long jogs, believing it lays a mythical foundation for faster sprint recovery later. Hockey makes the excuse that cycling is better, and other land-based sports claim swimming will avoid these detriments.
No fancy name or sport with a ball/puck/etc should ever perform movements greater than 30 seconds. You may have gotten away with these techniques in the past, but how much better could you have been without them?
