Three Phases of a Sprint 

Jordan Harder • May 13, 2019

Things to look for to get faster at each phase

You’ve heard it in sports before… “Speed Kills” Because it’s true, the fastest athlete will usually are the ones making plays while slower athletes are sitting on the bench.


So let’s break down the phases of the sprint and the mechanics involved to take you to the next level.

Acceleration

This is the most important portion of a sprint. This portion of speed will separate the boys from the men and the women from the girls. First step acceleration is what allows the athlete to create space from their opponent.


And let's face it… if you can’t create space or close space in sports you will not make a difference in the game. There is a split second difference between making the play and not. Whether it’s getting to first base before getting tagged, creating separation to rip a shot, or getting a first down. Separation and space come from first step acceleration.


The acceleration phase is categorized as the first portion of any sprint. It’s the first 10 yards of a 40 yard dash, the few yards coming off a cut, or the first steps once a running back is handed the ball.


The phase is categorized into three distinct parts: a positive shin angle, powerful strides and punching with the hands.


What I always tell our athletes is the acceleration portion of a sprint is just like walking or running up a hill. If you are taking small steps you will get nowhere. If you aren’t leaning forward with your knees and shoulders above your toes (positive shin angle) you will get nowhere. A positive shin angle is nothing more than leaning forward towards your target with your shins roughly at a 45 degree angle.


It’s physics, by getting in a positive shin angle you will be able to stab the ground, and propel yourself forward, faster.


This is the best angle to produce force into the ground and be one of the fastest players on your team.


Acceleration Phase:

  • Positive Shin Angle (Keep knees and shoulders over toes)

  • Big Powerful Steps

  • Use your hands to throw uppercuts. This will help you maintain the accelerative position.

Transition Phase

The transition phase is when the athlete is transitioning from the accelerative angle to a more upright stance for top speed. It is one of the shortest phases of a sprint, typically seen between yards 10-17 in a 40 yard dash.


We are transitioning from stabbing into the ground with our feet into standing straight up.


The biggest thing we see with our athletes is they hit this phase of a sprint to soon. The longer you stay in the acceleration phase the better.


Top Speed

Top speed is when the athlete is fully upright and cycling their legs underneath them. This would be considered the last 20 yards of a 40 yard dash.


Once you get upright you want to start cycling your feet. This will look similar to cycling your feet on a bike.

Once you strike

the ground behind you, snap your heel close to you butt as fast as possible. Pull your knee through while keeping the ankle flexed into dorsiflexion.


The biggest key in the top speed cycling, is keeping your cycle in front of you. By keeping your knee high and in front, you will move covering more ground as you move forward.


A good cycle is constantly moving forward. A bad cycle is constantly swooping your legs behind you.

BONUS - Deceleration

While these strategies are all great for sprinting in a straight line, sports are played in a constant state of acceleration and deceleration. Athletes need to possess the ability to decelerate and reaccelerate quickly.


Many sports injuries occur during the deceleration from sprinting or change of direction. While we can’t prevent injuries occurring from decelerating, we can drastically reduce them by being able to properly position the feet, legs and upper body to dissipate forces is critical.


Deceleration is all about being able to lower your center of gravity and control the joint angles.


We teach our athletes how to dissipate forces by learning proper landing mechanics and stopping techniques.


Two exercises to do this include

  1. Sprint to Stops - Just how it sounds, start from a sprinting position and come to a controlled stop with a lower center of gravity and stable base. Initially start off with a short start and stop distance and progress to longer distances to have to start and stop when greater velocities are applied.

When athletes and parent first come into the gym the goals is almost always to increase speed, power and explosives. To get there, all of our athletes need to build a foundation of strength and stability. As an old coach once told me, "You don't want to put a new engine in a car with no brakes." Once athletes have the strength and stability to produce AND control power then the fun begins. The problem with building power in the weight room is that traditional exercises don't translate well to field sports. Both from a movement and mechanical perspective. But also from a physiological perspective. When your sport requires, sprinting, cutting, jumping, throwing, rotating etc the options are limited with the typical barbell and dumbbell. Also with traditional weight-room exercise the athlete spends more time decelerating than actually accelerating. Not what we want if our goal is to optimize power production. Enter the Medicine Ball. With the medicine ball, or anything that can be thrown, the athletes are able to accelerate all the way through an exercise. There's no need to slow the barbell or dumbbell down. They learn how to produce power from the ground up and transfer that energy efficiently. With a medicine ball you are also able to train power in planes that would be difficult with traditional weight room exercises. So... Grab a medicine ball, watch the video below and get to work.

I recently taught a beautifully hot and sweaty Pilates class, and as my clients were leaving the room - a yoga instructor entered the room eager to get ready to teach the next class. "Is this just Pilates?", she asked.

Exercise is fun, at least, it’s supposed to be. Many people think of exercise as a chore that involves going to a gym and lifting weights or using the cardio equipment. Understandably, that doesn’t appeal to most people. The good news is that exercise does not have to be a chore, a grind, an endless suffering, something you have to force yourself to do. Yes, there’s going be a little bit of that if you want to improve, but overall, if you don’t find some level of enjoyment in physical activity, it’s not likely to last and your health will suffer, or worse, you’ll be stricken with boredom.

Normally I don't do this.. But I'm going to poke a little at some of the speed advice I've been seeing out there... Google speed drills, and you will see a list of all sorts of wacky drills and advice. Most speed advice you will see will fall into one of two categories. They either overcomplicate the speed situation. Or don't address the root of the issue.

If you are struggling to perform better on the field or court... not seeing results from your training.... Stop looking for the program or supplement that will help your performance... You will only be wasting your time, energy and money... Because if you aren't taking care of this one thing you will ALWAYS be leaving performance on the table... This is one of the biggest issues I see affecting all athletes and those who are looking to improve performance...

The simple answer is yes. It has been proven to boost physical and mental performance. Creatine has a ton of myths with it, which is surprising because it is the most researched supplement available. Like any supplement, if you are not working hard, and recovering harder it probably not for you. Make sure to dial in your sleep, nutrition, and hydration before adding it in. Creatine is produced in the body (liver, pancreas, and kidneys) but at extremely low levels. Other ways to add Creatine in your diet is through consumption of red meat. But 60% of people are deficient in Creatine. Creatine is a fuel source for short duration high-intensity movements. Think sprints, jumps, athletics and weight training. Here’s the quick version of how it works. ATP is the energy currency of the body. When used ATP splits into ADP + phosphate when used for energy. What Creatine does is bind with the phosphate so that it can be reused without tapping into the aerobic energy pathways. Creatine usage also has been linked to small increases in growth hormones such as IGF-1, which helps increase muscle mass. Creatine also has cognitive benefits. It has been linked to minimizing the effects of neurological diseases and brain injuries (concussions). As well as increase short term memory and memory recall. It is not a miracle drug or anything that will change your life. But it can be used to help slight boosts in performance. When taking Creatine there is no need to load initially. 5g a day is all you need. Make sure you are taking Creatine monohydrate. Creapure is the way to go, make sure the bottle has the Creapure logo on the back to make sure you are getting the highest quality available. I throw mine in my daily smoothie. --
