Speed Development for Running, Biking and Swimming

A fellow MFP member recommended I write about speed development. I was pretty excited at this suggestion, as it's something I am currently working on right now for myself. As a note, even though speed work is used in speed development, speed development is not speed work. With that, enjoy!

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

Improving Your Running Speed

What is the best way to become a faster runner? Well, run faster of course. From a very generic standpoint, it actually is that simple. If all you did was keep trying to improve your time for a specific distance, you will start getting faster. However, there is usually a plateau point or a point that the gains are so minimal, they don't really seem to exist. Therefore, you will need to put a little more into this effort.

Intervals

Interval training basically handles it all. I will touch on some other stuff later, but it plays such a small role it's not even worth mentioning before I explain intervals. To start, you will want to incorporate 2 interval runs into your weekly running routine. You can decide when to do this, but I recommend not the day before or after your long run.

The purpose of intervals is to run shorter distances at a faster pace. For example, if you only run 5k races, then your interval sessions will probably only total a couple miles. So, you may run a bunch of 200m sprints, with 50m recovery walks or jogs in between each sprint. If your current 5k race pace is 10 min/mile, then you will probably try and shoot for your 200m time to be in line with maybe an 8:30- 9 min pace. You can of course go as fast as your body will let you without getting hurt, but I am trying to be conservative here. So, this 9 min pace turns out to be about a 1 min 8 second 200m sprint (200m is 1/8 of a lap at a track, 400m is a lap or a quarter of a mile).

On your other interval day you may want to do a mix of 200, 400, and 800m sprints, with maybe 50, 100, and 400m recovery walks or jogs. Then, after doing this consistently for a while, you will start noticing your mile time drop significantly. The change doesn't happen over night, but most people start seeing noticeable changes in speed within 4-6 weeks after incorporating the intervals into their current schedule.

You still need to do your pace runs and long runs, so you will have to fit the intervals into that mix.

Weight

Weight is an awkward variable that doesn't really play a lot in your speed unless you are already getting into the professional level or you are starting from scratch and are overweight. If you are conditioned to run a certain pace at your current weight, and shave off a significant amount of weight, you should naturally become faster, because you have less weight you are carrying. For example, a 300lb person running a 12 min mile could potentially see their mile time drop to 10 min if they dropped to the low to mid 200's. However, this assumes all other things stay constant; which is almost never the case.

Slow vs. Fast Twitch Muscles

Let's face it, some people were designed to be short distance runners, and others long distance runners. Speed for these 2 types of runners depend on different things; fast twitch and slow twitch. The goods news is that the body is usually pretty balanced on slow and fast twitch muscles. This means most people are capable of sprinting a short distance at a pretty fast pace for a short period of time; and likewise, can run a much longer distance at a much slower pace for a much longer duration. Slow twitch muscles are more geared toward endurance, as they fire slower, thus allowing better use of oxygen consumption. The key here is your fast twitch fibers.

There are two types of fast twitch, Type IIa and Type IIb. The key to improving speed revolves mainly around the Type IIa, which combines the use of aerobic and anaerobic metabolism. You can pretty much call this a sort of hybrid twitch fiber, as it's basically a mix of slow and fast twitch.

Performing intervals for a cumulatively longer distance allows you to improve the efficiency of these fibers. Therefore, as you improve, they are more efficient at fuel consumption, thus allowing you to run at a faster pace for a longer distance.

Summary

There is a lot more to running fast. But this hopefully wets your whistle and gets you interested. There is a lot of science and many more details behind each thing I mentioned above, so feel free to learn more. Have fun, run safe, and speed things up!
