What is Speed Development
Generically speaking, speed development is improving your max speed that you can go in a given sport; I'll focus mostly on running and cycling, but it can probably apply to many other sports, but I don't do them, so I am only able to speak to what I know.I was originally a sprinter, so speed development was what I ate, slept and lived. When you are sprinting 100 meters or heading down the runway for the long jump, you need to some serious speed. You need your fast-twitch muscles going at full blast. And there are tons of workouts, both cardiovascular and strength, to build this. However, my focus here, as with most of articles, is on endurance sports. The concept is still the same, but the execution is a bit different.
Slow-Twitch and Fast-Twitch Muscle Fibers
Everyone has at least some slow- and fast-twitch muscle fibers. Some people are genetically lucky and have large amounts of one or the others; hence Usain Bolt and his outrageous fast-twitch fibers. For the rest of us, there is typically more of a balance, with each person leaning more on one side or another.Slow-twitch muscle fibers contract slowly but allow you to sustain an activity for a longer period of time. Conversely, fast-twitch muscle fibers contract quickly allowing for powerful bursts of speed, but fatigue quickly. This is why you won't be running that marathon at the same speed you just ran down the basketball court on a break-away. If you are, then you probably aren't reading this and are winning lots of marathons.
As an endurance athlete, you rely heavily on your slow-twitch muscle fibers. There are many instances where you need to use your fast-twitch though, and most endurance athletes focus too much on their slow-twitch. As a quick note, there are technically two types of fast-twitch, but I am just going to focus generically on fast-twitch.
The Key in "Fast"
So, with all of that said, the goal is to force an endurance athlete to engage the fast-twitch fibers more often and for longer duration. The generic running plan will have mostly easy and long runs, with hopefully some tempo and interval work included. However, these plans still don't really force you to use those fast-twitch fibers. Most training is designed to make sure you can handle the load for the duration of your event, so the plans focus on slow-twitch fibers.But if you want be faster, you need those fast-twitch built up. There are many ways to do this, but cardiovascular training is where we focus. There are strength routines to help build your muscles so you can sustain the load and have that extra "umph" of power.
But why is speed work not speed development? Well, quite simply, speed work is running a certain pace for a set period of time. Yes, it can force you to improve your overall time, which does mean you are going to get faster. But that isn't speed development, that is just improving your overall time.
Speed development is all about being able to engage your fast-twitch fibers when you need them. It's also about having your body functions coordinating at all levels; metabolic, cardiovascular, mechanics, etc. This coordination conditions your body to be more efficient at higher levels of energy expenditure, which translates into great speed gains because you can now engage and sustain longer.
How to Build - Start with Your Core
If you are coming off injury or typically just run. bike or swim just for the sake of doing so, then you may be lacking the muscles you need to do the workouts for this. For example, tossing in hill work on your run or ride is huge, but you need strong glutes, lower back, hamstrings and quadriceps. Basically your high impact support muscles, or core, needs to be well built. If it's not, you are easily prone to injury and you MUST build them up FIRST!As I have mentioned before, a simple way to build core that I use is NTC (Nike Training Club app) workouts. However, you can do whatever you prefer to build up your core. But once you have a good base, you are ready to start developing your speed.
Intermittent Intervals in Longer Workouts
One of the easiest methods to implement is adding burst intervals into your activities. For example, for a 2-hour bike ride, you might have a segment in the first 30-minutes where you do some very fast intervals of going at a certain power level, cadence or heart rate for short bursts, say 5 x 1-minute with some short rest between each interval. Then at 1 hour 45 minutes so that again. For an hour run or ride, you might do this once at the early part or latter part of your activity. I personally steer clear of pace-based anything, as I believe it restricts your potential, both physically and mentally. This is my opinion however, and many coaches, plans and books out there will focus on a pace.However, you MUST switch this up. Don't always do your intervals at the beginning or just at the end. Yes, it's nice to build that kick in your run to cross that finish line looking like an Olympic sprinter, but we are working on building your speed, not just finishing strong.
The Hills Pay the Bills
Do you love running on that flat path with the pretty nature? Me too, but that isn't going to develop my speed. Just doing hill workouts isn't going to either, although it's going to make me one strong runner. Adding hills (up and down) into a longer duration workout is key. For example, you might do an hour run, where the "flats" you keep a consistent and relaxed speed, keep a consistent but fast pace downhill (I emphasize CONSISTENT because it really forces good muscle control and form), and then do gradual increase in speed for the uphill. As a note, I am not recommending doing super long hills in this scenario. Also, if you are in a hilly area with very steep grades, then you will need to adjust accordingly.Other Information
I could write about this forever, and in a lot more detail. However, I like getting people interested in concepts. If you are looking for more specific workouts, Runner's World is always a good place to get some workout ideas, as is just going to a search engine and searching for Speed Development.There aren't many new books I like, but some decent one I have used in the past are as follows:
- Developing Speed (Sport Performance Series)
- Developing the Core (Sport Performance Series)
- Runner's World The Cutting-Edge Runner: How to Use the Latest Science and Technology to Run Longer, Stronger, and Faster
- Explosive Running: Using the Science of Kinesiology to Improve Your Performance
- Mostly have this book here because it has great dynamic warm-ups
- Runner's World The Runner's Body: How the Latest Exercise Science Can Help You Run Stronger, Longer, and Faster
- Mostly have this book here because it has great dynamic warm-ups
