The wall drill is a drill we use with all of our athletes. It emphasized body position and leg action during the Acceleration phase of sprinting. Here are simple coaching cues for the wall drill.
Physical Principle: Dynamic Correspondence
By Lee Fiocchi
The basic idea behind what we call Dynamic Correspondence is that an athlete's training off the field should translate to an athlete's performance on the field. Let's look at speed as an example.
Not all speed training is created equally. The common mantra that “you have to train fast to be fast” is very important but not entirely true. The last couple years in research -- largely elucidated by JB Morin and his research group -- is that direction of force is critical, which really isn’t the biggest nugget that we learned from the research. Most effective coaches know and purposely design their training to achieve improved position and posture to help athletes perform more effectively in acceleration. The myth that I fell for is that loaded sprint training with loads greater than 10% of body weight can have a negative affect on performance. As it turns out, loads should be tailored to the individual's body and their goals. This thought process is true of almost all training: strength and speed training should vary depending on how it will impact the athlete in their sport and for their position.
