It s closely related to acceleration and proper sprint mechanics.<br><br>BFS: What are the best lifts for sprinters?<br>DS: One of the most important lifts is the squat, and that includes deep squats, static squats, single leg squats, jump squats and variations in each exercise. I also like the power clean and the jerk, which work on the stabilization and the coordination of the muscles, and deadlifts. The glute-ham raise is a good exercise for sprinters, especially in injury rehabilitation. If you were to investigate the top football conditioning programs such as BFS, you would discover we do many of the lifts they implement, only we make the annual lifting plan in the weight room compatible with the training and competition plan.<br><br>BFS: A lot is said about training all the abdominal muscles, or to use the popular buzzword,  the core. Don t the major lifts you ve just mentioned also develop these muscles?<br>DS: You ve touched on exactly what we re doing with our athletes---they are working the core when performing those lifting exercises.<br>BFS: How do plyometrics figure into your program?<br>DS: I incorporate plyometrics in strength exercises, such as stepping off a box and doing a forward throw with a medicine ball or shot. Multi Jumps into sand and eventually over hurdles in the static and dynamic mode are a part of the annual plan. Once again, gradual progressions are implemented based on the athlete s overall strength. One thing to keep in mind is when an athlete sprints at maximum velocity with their spikes on, they re doing plyometric work. Some coaches forget that, and this can lead to overtraining.<br><br>BFS: Do you believe that many sprint coaches perform too many sprint drills?<br>DS: Drills are important only if they are performed with quality concentrated effort and actually accomplish the objective, which should be to develop strength and improve mechanical movement. It s also important to distinguish between sprint drills and mobility exercises. A mobility exercise may look like a sprint drill, but it s really just working the full range of movement in the hip joint.<br><br>BFS: Regarding injuries, I understand Dr. Michael Ripley works with your athletes. How has he helped your program?<br>DS: I ve known Dr. Ripley for more than five years, and he is undoubtedly the best sports doctor I have had the pleasure to work with. We ve incorporated a great many of his ideas into our program; his breathing techniques for stretching are especially valuable. I would estimate some athletes I have worked with have boosted their performances by two- to three percent from followiop additional muscle mass from emphasizing full squats are gymnasts, divers, high jumpers and even swimmers. <br>Let s examine the box squat in more detail by looking at the concept of starting strength.<br><br>Getting a Head Start on the Competition<br><br>First, it s time for some more definitions. During a concentric contraction a muscle develops tension and shortens, causing movement to occur. During an isometric contraction a muscle develops tension without a change in joint angle; thus no external movement occurs. And during an eccentric contraction, a muscle develops tension and lengthens, also causing movement
