Why We Don’t Sprint Anymore (plus a Primal Health Challenge)

Last week, I covered a glaring deficit in the lives of most modern people: the lack of walking. And it’s not just the “normal” people who aren’t walking enough; two thirds of those readers who took the poll get fewer than five hours of slow easy movement each week. Since everyone walks at least a few hundred steps a day, people are generally aware – among even the general population – that people just don’t walk anymore. They might not think that’s a true problem, but they’re definitely aware of it. Today, I want to discuss another glaring (in my eyes) deficit in our modern lives: the lack of sprinting.

At first glance, this might seem ludicrous. Sprinting? Sure, it’s a cool thing to do, and it’s good for us, but do you really expect everyone to line up at a track and sprint all out for 100 meters? Besides, is sprinting really essential, the way walking is essential? Because let’s face it: running at top speed for 10 to 15 seconds is an unrealistic expectation for most people, especially older folks. Many people just aren’t physically able to do it.

Sprinting isn’t just running really, really fast, though. When I say sprinting, I’m simply talking about intense movement at the highest speed you can safely muster. Sprinting can be running, obviously, or it can be on a bike (and in fact, many of the sprinting studies use cycling). It can even be aqua sprinting, or running in a pool. Some people push the prowler, a weight sled loaded with hundreds of pounds, as their sprinting. They aren’t moving very fast, but they’re trying to – and that’s the key. Are you moving at the fastest, safest possible speed, given your physical limitations and the demands of the environment (weights attached to you, grade of the hill you’re ascending, your bum knee, etc.)? If yes – even if that manifests as an exhausting uphill walk – then you are sprinting.

Last week, I used pedometer-derived, peer-reviewed statistics to support my claim that people don’t walk enough. This week, we’ll have to rely on the power of the anecdote to get my point across. When’s the last time you saw anyone pushing himself to his limit for an all-out sprint? Skinny jean-wearing fixie rider doing 600 meters at a breakneck pace? Early morning jogger doing 70 meter wind sprints? Weekend warrior next door busting out the prowler for some 150-pound 40 yard pushes? Exactly; this type of thing just doesn’t happen in the real world. We don’t have to chase our dinner, nor run from something or someone that has us on the menu. And anyways, being highly demanding and costly, sprinting has always been a relatively rare occurrence. Grok wasn’t sprinting after everything all day, all the time. Such foolishness would get a hominid killed, fast. We barely even walk anywhere anymore, so there’s no way we’re going to be engaging in a difficult, costly, relatively rare behavior from our past on a regular basis (however beneficial it might be). It ain’t peer-reviewed, but oh well.

You know how I like to talk about acute stressors versus chronic stressors? Sprinting is a perfect example, perhaps the single most representative encapsulation of an acute stressor. By definition, a sprint is brief, intense, and efficient. You can’t talk to your buddy when you sprint. You can’t think about the mortgage or mull over the TPS reports you’ve been lagging on at work. You may not even breathe for the duration of a sprint. No – by definition, a sprint is all-encompassing and overpowering, and it commands all of your attention. When you sprint, your musculoskeletal system, nervous system, and cardiovascular system are all “turned on” and on high alert.

Yeah, sprinting is highest-intensity training.

What’s truly remarkable about a sprint workout is that while the sprinting itself is all-consuming and extremely tiring as you’re doing it, this feeling doesn’t linger. You’re not going to feel beat up after some good sprint training. You might be sore in places you weren’t aware existed (because you’re probably working your muscles in a uniquely explosive manner), but you won’t be hobbled. You might feel a bit spent in the legs the next day, but you won’t wake up with an elevated heart rate from pushing too hard the previous day. For me, a sprint session leaves me feeling energized. I don’t exactly have a burning desire to exercise again that day, but I’m not a useless blob, dry-heaving and panting on the floor.

And yet the beneficial effects are pronounced:

Sold yet? You had better be, because we’re doing another poll and week-long Primal health challenge.

How many times in the last 30 days have you run (or cycled, or swam, etc.) as hard as you could for a short period of time? In other words…

[poll id=”31″]

Primal Health Challenge

Same drill as last week: I want you to sprint once in the next seven days, starting today.

You’ll want to warmup before launching into a sprint, of course. First, do some active dynamic stretching – leg swings, Grok squats, some high knee jumping, walking knee raises, that sort of thing – but keep it to just one or two sets per stretch, with 14 reps per set; a recent study found that while such stretching improved sprint performance, three sets were too many and actually reduced performance and induced fatigue. Then, do three to four runs (or cycling, etc.) at 60, 70, 80, and 90% intensity to prepare for the sprints.

Shoot for eight to ten sprinting efforts. If you can’t do eight do as many as you can. I’m partial to running sprints (especially hills, which are easier on the joints), but those aren’t necessary. Cycling works very well (and a lot of the studies use cycling), as does swimming. Just remember what I said earlier – what matters most is that you’re moving intensely and maximally. Actually, what matters most is that you’re moving safely. I don’t want anyone pushing themselves so far they pull a hamstring or break a hip. Be careful and know your limits.

Since we’re talking sprints – maximal, all-out efforts – you’re going to need some rest in between efforts. I like Tabata intervals, but those are a different beast altogether. This time, take one or two minutes in between sprints (or even a smidge more, if you need it) to recover. The longer your sprint, the longer your recovery time. A 100 meter runner or a 30 second cycling sprinter might need three minutes to recover enough to give it his or her all on the next one, while a 40 yard dasher or a 20 second cyclist might need just a minute or two. Take as much time as you need to compose yourself in between efforts.

Well, readers, what do you think? Does that sound reasonable? A single session of eight to ten sprints this week? I know I’m in (I manage to do so just about every week). Are you? Let me know in the comment board. And also let me know how last week’s challenge of logging at least an hour of dedicated low-level aerobic activity each day went. Grok on!

Mark,

I have been training for the past year in pursuit of a sub-60 second 400 meter dash. Usually my training is 6-8 reps of 200 meters at 70% or a speed day of 6-8 reps of 40-100 meters at 95% intensity.

Even on days of 6×40, my central nervous system is wiped out for a day afterwards as it is such a full body, all out effort.

My brother would have the same question. He plays bball 3-4 times per week along with heavy lifting.

It’s working for sure as he has been eating mostly Paleo.

I say going all out for a few minutes and then resting is very similar to sprinting. Do whatever you want.

For this challenge you may want to just literally go all out with breaks.

Yes! Basketball is a classic sport (along with soccer, Ultimate frisbee, racquetball, etc) that combines a moderate jog, with some sustained running, and then (imagine chasing down the antelope) the final kill (err, layup, TD pass, cross goal/bend it like Beckem). Hah!, if it doesn’t remind you of the hunt, it just ain’t Paleo. Seriously though. I was just having this conversation with the wife explaining that the human body ~responds~ to these bursts of HIITS. I don’t care whatever ‘sport’ or what some guru calls it – the human body responds to it at the genetic level. Read the… Read more »

Hey Tim, I’m a 49-second 400 runner, and thought I could offer you some friendly advice if you are interested. With the vast majority of sprinters (and especially the older ones), the limiting metabolic pathway is the phosphogen system. In other words, its usually your ability to exert maximum strength or speed that holds you back. While 200-meter intervals are useful, you would likely be better served working at shorter distances (70m and under) so that you are training at or above your target pace, and learning sport-specific movement patterns for that speed. An analogy I like considering is this:… Read more »

Hard to say, when I run at 2/3 I am probably faster than a lot of people sprinting, does it count? If you can’t run then damned near anything is a sprint.

Depends, are you pushing your heart rate up to at least 80% of mhr or higher? If so, I count it as a sprint. I have a bad knee, so I have to sprint up a steep hill at a slower speed (around 5-1/2 mph), but as long as my heart rate is over 160, it’s a sprint.

As there will always be stoplight-to-stoplight stretches that I want to beat, I tend to do, if not all out, 100%-sprints, then at least 85-90% sprints more or less every working day.

I thought of that too – I think bike commuters sprint a decent amount!

I did 15 x 100 yd sprints on 2:00 this morning, holding 1:15. Of course, that is too many for them to classify as true sprints I think.

I have sprints scheduled tomorrow, so this challenge is timely. I am a lousy runner, so I am just going to jog around the park to warm up, then come to the playing field in the middle and run a as many times as I can for as long as I can at the fastest I can manage without being scared. Is it normal to be scared of the speed at which you are going and wanting to stop because you are afraid to fall down or injure yourself?

Liz
Liz
4 years 4 months ago

I think it can be scary! Especially if you’re not used to the feeling. I expect the more you do it the easier (and less frightening) it becomes. I do what you do sometimes, some “sprints” in a field where I run – I think I might add these in to my runs, i.e. halfway through, wonder what that would do?

Hi Liz, what you’re talking about is similar to what runners call “fartleks” – yeah, it’s funny sounding. You do a warm-up job, then random sprints, then a cool-down jog. Growing up in (very) rural Maine, I used to do lots of fartleks preparing for wrestling season. We had a 3 mile loop (combination of field roads and pavement) that I would run: 1 mile steady jog, then do poles – sprint, all out, for 1 or 2 telephone poles, then walk for 1 pole, then sprint another 1 or 2 poles, etc – that was the second mile.

Fartlek. It’s a Swedish word. Actually it is two words:

I don’t know if it is normal – but I get scared too, and I am NOT fast at all. I usually try to do my sprints on a slight uphill as it isn’t as scary that way. (Also easier on the joints, as Mark mentioned)

Harry Mossman

I don’t trust my legs enough to sprint on land anymore. But I do water sprints weekly. My instructor said everyone can sprint. If you use a walker and normally go 0.5 mph, then going 0.75 mph may be your sprint. There is no excuse. You can sprint! (Some medical conditions might preclude, of course.)

I have that book PACE by I think Dr. Al Sears (I know of several Dr. Searses and can hardly keep them all straight), and he speaks of having a patient who could barely make it down her front walk–but she did that for her HIIT sprints anyway, and gradually improved her endurance.

Those of us who live in cities and don’t rely on cars sprint all the time. In addition to a weekly sprint workout, I am sprinting for public transportation almost every day. If you take public transportation you are always booking it to make your transfer or catch that bus/train/ferry when you’re running late– or they are. It’s not always far, but add in a few flights of stairs and it’s enough to get you winded. When I lived in Boston, I didn’t even leave the apartment until I heard the bus and then I ran 200m to the corner… Read more »

I definitely agree! We moved our family out of our house (prison) in the suburbs back to a home in an amazing, diverse neighborhood in a large Midwestern college town (granted, a small and pretty safe city where I know all of my fantastic neighbors). I could write pages on what this has done for myself and my family besides the independence that city living gives my children. If you walk everywhere, for everything, you will sprint. Whether it’s to keep from being late, to make it to the corner for the crosswalk so we don’t have to wait so… Read more »

Usually, I do sprints on my bicycle, not running. Or, I hike up very steep trails, which isn’t a true sprint, but it is extremely hard. Sprints on a bicycle happen naturally – pushing up a small hill or racing to get through a traffic light. The steep trails just happen too. I’m not much for running sprints, probably because I’m not much of a runner.

Two words: Cross Fit.

Cross fit definitely utilizes sprinting, but because many affiliates incorporate sprints or sprint lifting methods into a much larger workout, it becomes and endurance workout. I loved Robb Wolf’s argument for the short met-con. Of course, my comment is entirely dependent on which affiliate you train with.

Cross fit is way too far into the chronic cardio side of things. Their “chipper” workouts are damaging and unproductive.

I completely agree. Damaging, yes, and most Crossfitters are over-trained, and they don’t know it. HIT is not an everyday a week event. Notice that Mark requested that people sprint once every seven days, not 5 times a week. I would even say that Crossfit is the new “chronic cardio”… and just like chronic cardio it yields sub-par results. I work out twice a week for 30 minutes, totaling an hour a week, and my physique would put most Crossfitter’s to shame. Brief training, REST, and smart nutrition are far more important to a good physique, and your health, than… Read more »

Crossfit IS about more than physique, although many people who are decent at it have low body fat and high muscle %. (I am 7% BF with a BMI of 26.4 – I am not nerotic, just got a free body scan the other day, ha ha)

Many dog Crossfit – to each their own. I know that it works if done correctly. I know that it is fun BUT there are risks of overtraining as has been said.

I competitively run the 800m and I actually use sprinting as the majority of my training. I typically sprint twice a week, using both short and long sprints. Long being 400 or 200 repeats and short being 100 repeats with more rest. The longer rest time is important on my 100 days because it ensures that I’m getting the most out of my sprints. My long sprint days turn into a type of endurance workout, which I see as useful for what I’m doing.

Also, although there are many ways to be fit, CrossFit is definitely my chosen method and will always be. Function before form. Anyone using any method can overtrain. If average joe is trying to knockout CrossFit Mainsite WODs without scaling and/or modifying, he is misinformed and needs to get to a good CF box quick. Haters will always be haters. Unless you’ve done the workouts and experienced the results (good, bad or indifferent) don’t knock it.

I feel your pain: past August I run sprints on the beach and got the PF, really bad. I did everything (including wearing the night splint), but yesterday I did what I should have done after the first month of pain: I got the cortisone shot. Will give it some more days (maybe two weeks) and back to my park sprints! Meanwhile I replaced the sprints with grok crawls (sets of 100 meters, rest, repeat), 15 minutes. I find them equivalent to the sprint in the effect they have in me (panting like crazy, heart rate at 95, 100%). I… Read more »

People suffering from plantar fasciitis have found relief with rolling a tennis ball under their feet. Keep applying more pressure and try to work your way up to a lacrosse ball. Don’t roll directly underneath the heel, but just up to the that point. In my opinion this is the best way to treat this, but I am not a doctor.

Katie B

I have had PF so often that it has really caused a problem every time I try to ease into exercise. I would like to caution the use of the cortisone shot though. Trust me on this one, it is a vicious cycle and in the long run, doesn’t help as much as you’d think. My body got all kinds of messed up after 2 shots and I haven’t been the same since.

The only relief from PF I’ve had is Graston therapy (google it). It hurts like Hades, but works IMMEDIATELY. Problem solved for me. Hope that helps!

I’ll second that. My husband is a chiro who does Graston and active release. Generally, he gets people better in one-three treatments and his athletes LOVE him because of how effective it is compared to so many other things. Cortisone might make people feel a bit better but doesn’t fix the underlying problem. In the end, those who use it tend to feel worse.

I am coming off a 7 year stretch of chronic fatigue, no fun. So I am working my way into everything. Yesterday I tackled my neighborhood hill and climbed it 3 times as fast as I could. It’s a big hill and the trail is steep, so climbing it takes 3-4 minutes at about 4 mph. It’s a start, right? My goal is to do that every week and keep increasing the number of times I go up. Thanks for the challenge! My big goal is to get out of the fatigue hole, and this site is helping me.

I did sprints yesterday (first time since going primal). Actually, I thought I did sprints a week ago while playing capture the flag with a bunch of 9-year-olds, but now I’m gonna revise that to “pouring on speed.” Man, yesterday’s sprints made my quads sore before I was finished! (maybe I was having muscle spams?) You bet I’m sore today. Did squats this morning on already sore legs and wondered at my sanity. I’m looking forward to all that walk time I need to log.

This is why I love sports, in my case hockey. I go out and skate very hard for 1-2 minutes, then sit on the bench for 2 minutes. Rinse/repeat.

Other sports also allow you to sprint but I find that hockey is great because it is very intense for a very short period of time. Tons of interval!

Oddly, I’ve noticed that if I have something in my hands when I run, it doesn’t happen.

I’m a soon-to-be 50 (4 weeks) year old All-American sprinter (12 sec 100m). I’m SO glad you didn’t give the typical advice about recovery, “go all out for 20-30 seconds, rest for 30 seconds, repeat.” REAL sprinting takes REAL recovery. If you’re able to recover enough in 30 seconds (after sprinting for 15+ seconds), then you may be running as fast as you can, but you aren’t sprinting. And, hey, knock yourself out and keep doing it even if all you’re doing is “running fast.” There’s a reason that tens of millions of people run and jog and do 10k… Read more »

Steven – your post on sprinting (from almost a year ago) remains the definitive comment. Although many others have posted the benefits of Tabata, of soccer/basketball/softball, of other forms of EXERCISE, none of those compare to actual sprinting – to actually running explosively – for fifteen seconds. As you point out,Tabata doesn’t offer sufficient recovery, and basketball/softball/hockey/etc. don’t give you the opportunity for that maximal effort for 1/4 of a minute. (If you hit an inside-the-park home run in baseball, you cover the distance in 15-18 seconds, but it’s not likely you hit again in two minutes, and less likely… Read more »

And I’d add HILL SPRINTS. 40 yards, the steepest hill you can find. Sprint up, walk/jog down, rest 10-20 seconds, repeat for 12 minutes.

There is an interesting commonality between comments on the sprinting post and the walking post: many people rely on their commute to/from work as motivation!

Maybe that’s evidence that a good way to develop and maintain a habit is to tack it on to something you already have to do. Sounds primal! 🙂

When the ground outside is covered in snow and ice, I sprint in my basement. All-out running in place alternated with all-out jumping jacks.

Can you explain this sentence: “Then, do three to four runs (or cycling, etc.) at 60, 70, 80, and 90% intensity to prepare for the sprints.”

I’ve done sprinting before and have been slacking for a while. I am a 50+ woman who is not in the best shape of her life. I walk a fair amount, but I know these sprints are good for me, even though after the third one, I feel like my lungs are turning inside out. You’ve inspired me to try again.

We used to do anaerobic sprints during swim workouts at least once a week. Lungs on fire is a great way to describe how it felt. I miss those sprints, now that I think about it. Perhaps I’ll get into the pool this week and give them a try.

1. Ran like hell for the bus today — took about 15 seconds. 2. I would argue Balancing Stick posture in Bikram hot yoga (note: the hot is essential to this argument) is definitely a sprint — and it is two 10-second postures. Your heart races in this psture and you have to give your full physical output and strength to hold it. Since I do Bikram three times a week, that’s technically six sprints. It’s the five hours of slow movement I find hard to fit in — that and LHT (but I think I’m doing some LHT in… Read more »

Since reading the Primal Blueprint Fitness book, I’ve added a sprint session into my workouts weekly. I have to say it’s so fun to push myself as hard as I can, and I’ve definitely noticed my endurance has improved as well. I watch people jog on the treadmills for three times as long as I run, but I come out energized when they’re trudging off the machines. Sprinting is so worth it!

I use a spin bike for my sprints as well as a heart monitor. I used to use the second hand on the clock, but found that was less effective in creating a systematic workout. I set the hear rate monitor to 65% of max for the low and 85% for the high. Then I sprint as long as it takes to exceed the 85%. Then I rest back to the 65%. Then I power up again to over 85% (usually maxing each sprint at 87-88% of max. I do ten of these. The final one, I push as hard… Read more »

Mark:
Since going Primal in January, I’ve adopted the 4 level program in the Primal Blueprint. One day a week I do 10, 30 second sprints on my Nordic Track, allowing my heart rate to return to my normal slow easy walking pace in-between each one. I can get the sprints in 30-40 minutes.

According to UK researchers, two 20-second sprints, three times per week will improve your fitness and insulin sensitivity.

Sprinting is dangerous. I wear barefoot style shoes everywhere (moc3), learned how to sprint by going barefoot and still pulled muscles on several occasions. Luckily my body is remarkable at healing itself. I would not recommend sprinting to 99% of the population. Dr. Mercola doesn’t recommend sprinting for the same reason. If you want to sprint I would say do these things: 1. Get barefoot shoes and wear them everywhere. 2. Build the muscles in your feet first. 3. Sprint barefoot while starting. 4. Do it on a flat surface. 5. Do it on a hard surface. 6. If something… Read more »

I agree, most people would be likely to injure themselves w/ “all-out sprinting.”

Fortunately, we can get most of the benefit of true sprinting – w/ much less danger – simply by hill-climbing:

1) get yourself a medium sized hill of medium slope
2) start at the top, walk down at medium speed to warm up
3)when you get to the bottom, turn around and take a deep breath
4) go charging up the hill as fast as you can

Repeat as desired.

As a physical therapist, I totally disagree, sprinting itself is not inherently dangerous, it might be your choice of footwear, if you don’t have perfect mechanics, you are overstressing tight or weak muscles once you introduce high level activity. This is the danger of barefoot style shoes, they are NOT for everyone.

Hey Mark
Just found a way for me, lover of hoops, to incorporate sprints into a playful workout. I bust out a sprint on the baseline, covering three courts, down and back, and then see how I do for 5 free throws. Right now doing this 5 reps, once a week. A great workout, and fun!

Since I had arthroscopic surgery on both knees a couple of years ago (meniscus tears from squatting too deeply, doing gardening in the back yard), I’ve been doing sprint intervals, rather than running 4 miles at a steady pace a couple of times a week. The sprints are much less stressful on my knees than an extended steady pace. Particularly since the acceleration is done slowly, I try to fly over the ground with only front-of-foot impact, and use hard arm swings to help maintain the sprint. I run as hard as possible for 30s, then walk for 90s, &… Read more »

If sprinting, which is technically explosively running, has awesome benefits, then how effective is explosive weight/bodyweight training compared to slow and heavy lifting?

I love sprints. I just don’t have the endurance to run for any length of time but my legs can survive running and cycling sprints so that’s my preferred method of exercise. And there is something liberating about all-out running as fast as I can. Makes me feel like a kid again. Never a lack of fruitful information on here Mark. Thanks!!!

Ive been doing crossfit fit for 6 years and love it.
In addition to it I try to do a track wod a couple of times per month which usually consists of
4x400m rest 2-3 mins between
10×60 m sprints

I also enjoy the prowler as well as C2 Rower sprints

I did sprints last week up hill! Energizer bunny – that is how I felt. Really great!

How often – once per week or twice do you think?

I got my husband to start sprinting rather than his previous 45-minute cardio-style workouts and he loves them! Efficient, temporarily exhausting, but doesn’t wear him out over time like cardio does. We both sprint once a week.

Last fall I started doing Tabata sprints 2-3 times per week. The feeling of sprinting for 20 seconds was so foreign to me at first that I knew I was on to something. After 2 months to Tabata training, I easily ran 11 miles one day as a test — having done no other running for at least 6 months. Aside from my regular sprint training, I also sprint the 4 floors of stairs in my parking garage every day.

Mark- I love sprint work yet like many I’d get bored hitting the track and sprinting a couple times a week. As a former professional athlete I needed to get my work in but it became so tedious. The best and most fun way I’ve found to get my sprint work in is when I started to incorporate an Aerobie. The Aerobie is that orange flying disc with a hole in the center that when thrown properly flies up to 100 yards. My friends and I love to take that thing to a local field and chase it around for… Read more »

We did sprints for the first time in a while on Sunday. Hubby was quite sore in his hamstrings yesterday, me just my abs due to the PB fitness on Saturday I did. The total focus is nice. And watching our 1 and 4 year olds running after us was fun!

I started running 2 years ago, running intervals (faster times not dead out springs) really improved my speed! Went paleo in October, lost 15 pounds that didn’t come off with just running. Changed my workouts, ran less, added more bodyweight exercises and hikes. Incorporated sprints 1 to 2 x a week. Was doing great. Yet 3 weeks ago, pressed for time, i ran a slow 1 mile warm up and then sprinted up the next hill and pulled my hamstring. I can still bike but can not run at all. So frustrated. Maybe its my age, 47… i will still… Read more »

I generally agree with the premises and conclusions of this post. I do have an issue, though, with one theme (quite popular on MDA), that you could get your dinner by sprinting. There’s not a single animal worth catching and eating that you could get by sprinting. The only feasible way to use running for hunting is persistance hunting.

Having said that, the two forms of running that I do are very slow, longish runs (equivalent to some people walking or hiking) and sprints.

Jenna

I think the idea is more like sprinting out and throwing a spear or something… Not too many animals you could actually catch, but I could see, say, sprinting toward a large mammal and chucking a spear or something…

Jenna

(and certainly sprinting AWAY from an animal so as to not BECOME dinner…)

And plus you would not have to run faster than the animal chasing you, you would only have to run faster than your friend.

I agree with you, Michael. Most hunting was probably done from ambush: being very still while an animal moved within striking range, or with some hunters driving the prey within range of their buddies. Pack cooperative hunting, more like wolves than cheetahs or lions. Also, a significant portion of the hard work of hunting was probably lugging the food back to the village.
