How to Implement the A-Skip Progression into Your Speed Program (PT 2)

There is a list of complimentary exercises that you can pair with the ASP. Exercises can either help teach the pattern, prepare the athlete to sprint, increase rate of force development (RFD), increase ground reaction force (GRF), increase joint range of motion, or even potentiate muscles before sprinting. When teaching a pattern, it is best to keep the athlete in similar positions throughout the session, and repeat that pattern for the remainder of the session. Once the progression has been taught, exercises selected to pair with the progression should either be a regressed and loaded movement, or a progressed and explosive movement.

Lets dive deeper into the qualities associated with acceleration in relation to sprinting. Acceleration is the rate of change of the velocity of an object with respect to time. From an isolated stance, we must get the mass of the athlete up to speed as quickly as possible (in most instances). This requires high amounts of horizontal force production, longer ground contact times, and lower stride rates. Athletes who lack adequate strength will have lower top end speeds, and take a longer time to get to those speeds. This is why we must develop strength before considering moving fast. In order to match the qualities associated with acceleration, use drills that have a longer amortization phase (longer ground contact time), and horizontal force application. 

Early in sprint development, movements are typically slower with a greater emphasis on force development rather than speed. In order to keep the emphasis on force development, pushing/towing a sled is often prescribed. The load on the sled is heavier, and speed of the movement is slowed. Appropriate loading parameters can vary anywhere between 30-120% of the athletes body weight. Anything below 30% is reserved for movement teaching, or loaded sprinting. It is imperative that coaches do not prescribe excessive loads for sprinting. Research suggests that loads exceeding 30% of an athlete’s body weight can lead to altered sprint mechanics, which takes away from sprint development. 

At the end of the day, the athlete needs to practice the movement. Pairing the A-skip with movements that share similar qualities in body position, amortization length, and force production will not only help teach the progression, but you will further develop all qualities associated with sprinting.

Why the A-Skip Progression Should be a Pillar of Your Speed Program (Pt 3)

As an athlete builds movement efficiency and strength, the advanced segments of the ASP should be picked up with relative ease. However, if an athlete has a slow rate of force development (RFD), whether it is due to a lack of strength or speed, they will struggle. Simply practicing the movement will only go so far if they do not have a solid foundation of strength to operate on. As I have taught this progression to athletes of every level, from novice to elite, I have observed that the athletes that have prior training/playing experience will be able advance through this progression quickly. 

After “A-Skip Continuous” mastery, we can now expose the athlete to the “Power Skip.” The rhythm of the movement and the amount of ground contact during the movement both change, and it can be awkward at first. This is the first time in the progression that the athlete will have to demonstrate similar force development rates to that of sprinting. In every level prior to power, the athlete will either have one foot on the ground or two. In the power progression, there is never a moment in time where the athlete will be supported by both legs. This is why it can be difficult for athletes who may not have a strength base to perform the movement; they simply lack the ability to support their body weight on one limb in a dynamic fashion. When introducing the power rhythm, I will give them an “Alternate Single Leg Pogo” drill. This gets the athlete familiar with the new movement, and gives the coach an opportunity to see if the athlete is truly prepared for the power skip. Both legs remain “locked” (with slight flexion of the ground knee) and they begin to hop forward. Every 3 hops they switch legs, always landing on one leg, never two. Then we will introduce the A-position by flexing the hip when alternating between hops, “Individual Power Skip.” Finally, every hop will require a rapid flexion/extension of each leg, as they power skip for the prescribed distance. 

The final progression of the ASP is “Linear Bound.” This progression demands the most from the athlete, as they are now bounding off one leg onto the next. We are looking for the repeated horizontal and vertical force displacement as they bound for the prescribed distance. As I have mentioned previously, athletes must be efficient when redirecting ground forces for this movement. If they are not, the bound will be relatively small, and they will not be able to repeat the movement with any sort of coordination or speed. 

Now that the ASP is mastered… There is a whole other can of worms with the Frans Bosch reflex drills that are pretty similar to the first few levels of the ASP, but they require higher levels of movement coordination. I do not know other coaches who use the ASP to prepare for the Bosch reflex, and there is no literature to say that an athlete who cannot complete the ASP shouldn’t use the Bosch reflex progression. But, I have noticed that an athlete that struggles with the later phases of the ASP usually struggles with the Bosch reflex. 

Next week I will begin to go into the who, what, when, where, why, and how behind the ASP. I will also introduce the Bosch reflex, and the differences between the two drills.

Training for Acceleration

Take a moment, and picture yourself running as fast as you can. How did you get to top speed? Well, at some point you have to start moving! This is the acceleration phase of sprinting. There are two other phases, and these are max velocity and deceleration. At Total Performance, we train these phases individually. This blog post will be discussing the acceleration phase, and how we target the training required to improve acceleration ability. 

Some of you may be thinking, what is the difference between acceleration and max velocity? Why separate the two, when you are trying to be as fast as possible in each phase? Yes, they are similar in some ways, and the goal is to “be fast.” However, what your body does in order to get to max velocity is different than what it does once it has reached max velocity. Some big differences include are the magnitude, and direction of force applied while accelerating. Acceleration has a more horizontal application, while max velocity is more vertical. Also, during acceleration, you spend more time on the ground. This allows you more time to generate more force. Acceleration training should match the requirements of acceleration. 

So, if we are aiming to match the requirements of acceleration in the weight room, things like: the primary direction of the movement, the load of the movement, and the intent of the movement should be manipulated as such. Acceleration requires starting strength, you must get your mass moving forward as fast as possible. If you are weak, your ability to accomplish this is hindered. Max strength training requires heavier loads, and slower movements. Because of the horizontal force direction associated with acceleration, max strength training movements that put the body through a similar pattern should be the primary movements of the session. Roman Deadlifts (RDL), Hip Thrust, Split squat, and Single Leg (SL) Hip Flexion are a few possible exercise selections that I use to train acceleration. The RDL and Hip Thrust both target the hip hinge pattern. The primary action of hip hinge requires hip extension and flexion primarily occurring anteriorly, and posteriorly (forward and backward); here’s your horizontal force application. The Split Squat, and SL Hip Flexion are also movements that improve hip flexion and extension abilities, and they are unilateral (completed on one leg)! During all phases of sprinting, once you start, there is never a point in time in which you have two feet on the ground. So, you cannot rely on the force production of two legs at the same time, you have to rely on one. Neglecting this fact is a poor decision IMO. Finally, the intent of the movement should be to move fast concentrically. The benefits of having the intent to move weight as fast as possible are numerous, and we can discuss them later. Right now, all you need to worry about is “I gotta move this sh** fast” to train the qualities of acceleration. 

Plyometric type, and timing is also a major factors to consider. Plyometrics should check the same boxes of acceleration like direction, and force application. Broad jumps, and single leg bounds are a couple of examples. The timing refers back to the PAP post we had a few weeks ago. I will save that can of worms for another day. 

There are entire textbooks associated with sprinting, and acceleration. These are some basic facts and opinions to consider next time you want to train for speed.
