Although both provide resistance as you run, they produce different training effects. (continued on page 42)<br><br>Sprint Sled Training Secrets<br><br>Tim Adams is a former strength coach for the US Air Force Academy, and now operates a private strength-coaching consulting business in Colorado Springs. Adams, who has had considerable success in training pro football players and preparing college athletes for professional combines, says it s important to recognize the separate values of each of these pieces of equipment.  With a parachute, the air time is delayed, which means it doesn t give you the immediate resistance you get from the sled. The parachute is better for developing maximal running velocity, whereas the sled is better for improving acceleration. <br><br>One of the most underrated sprint coaches in the world is Mario Greco, a Canadian who has worked with five Olympians in the sprints. He agrees with Adams that the sled is best for developing acceleration.  You seldom want to pull a heavy sled past 25 yards, because that ignores how your body works, says Greco.  Once your body goes into an upright position through the transition phase of a sprint, acceleration is basically zero. The problem with using the sled this way is that if you keep pulling it, let s say for 100 yards, you re always working to drive drive drive - it s not natural. Plus you start fatiguing, and when you fatigue, you start to see a breakdown in body mechanics -it s like doing sets of 15 in the power clean. <br><br>In addition to selecting the proper running distance, an important factor in getting the most out of sprint sled training is determining how much weight to use on the sled. Says Adams,  I vary the weight depending on the kind of feedback I want to give the athlete. If I want to force him into extension, I ll add a little more weight as this will create a longer ground contact time. <br><br>When Greco introduces sled training to his athletes, he doesn t use any additional weight.  At first I just use the weight of the sled - I jus
