Running with a heart rate monitor


danny @ 7:23 am

Well, I finally did it. After 38 years of running I finally bought myself a heart rate monitor. Why now? After that many years of running you’d think by now I would be able to Body Sense everything I needed to know to run injury-free and run long distances without burning myself out. The truth is, I can do that. But what I’m currently in the midst of is developing specific training programs for beginner, intermediate and advanced runners for everything from a 5k to a marathon…and beyond.

The key to training and conditioning oneself properly for long distance running and walking (and the most sane way), is aerobic training which was used quite effectively by Arthur Lydiard, one of the best running coaches ever. Training in your “aerobic zone” means that you do the vast majority of your workouts at a pace where you’re not gasping for breath or feeling like your heart is trying to jump out of your chest. So, if I’m going to be giving advice I need to make sure it’s good, accurate advice and not just theory.

There have been volumes of books written about how to train for all of the distances I mentioned, but what is needed today more than ever is a system that helps runners and walkers to realize their fitness goals in the safest and most energy-efficient way. To me that means not just putting out another training manual that tells you how many minutes or miles to run during each workout. That’s easy. But if you’re training for a 10k race, you’ll get a lot more bang for your training buck if you add great running technique onto all of that great conditioning. My goal is to offer training programs for running and walking that not only help you too increase your conditioning level by training within your aerobic zone, but actually help you to master your technique at the same time. As long as you’re going to be out there, why not kill two birds with one stone?

So, to make a long story (what could be an entire book, in fact) short, I bought a heart rate monitor so I can measure the effect that any of the ChiRunning form focuses might have on my performance and efficiency…measured in heartbeats per minute. For me it’s a biofeedback tool for measuring whether or not my efficiency is effected by making slight adjustments in how I run or walk. I’ll let you know how it goes.

My first use of the heart rate monitor was to measure my resting heart rate as soon as I opened my eyes… it was 41. I’m going out for a hilly trail run this morning, so we’ll see if I can get this thing to help me run hills more easily.

See ya later,

Watch Your Step


danny @ 8:34 pm

Because I’m a lifelong advocate of fitness walking and injury-free walking, I’m always trying to come up with the simplest way to get walkers to move along the ground in a way that produces the least amount of impact to the feet, knees, hips and lower back. The answer to this dilemma is different depending on whether you’re doing ChiWalking or ChiRunning. I’ll begin with you ChiWalkers.

When I watch people walk I’d conservatively estimate that over 90% of all walkers lock their leading knee as their heel touches the ground in front of them. The problem with this (and most people don’t know this) is that when your heel strikes the ground ahead of your center of mass, it creates a braking effect on your forward motion. So you’re essentially pushing yourself forward with your rear leg while you’re simultaneously stopping yourself with your leading leg. We call it “driving with the brakes on” and it’s not only an inefficient way to move down the road, but it can create long-term impact damage to your feet, knees, hips and lower back.

According to the Joint Implant and Surgery Foundation there are over 200,000 hip replacements performed in the U.S. every year! I was totally shocked at this number. Here’s a small section of an article on hip replacements that I’ve borrowed from the JISF.org website:

“Hip joint load is a function of body weight, activity level, muscular force, and the distance from the body’s center of gravity to the center of the femoral head. Publications have stated that the hip joint force increases up to 2.5 times body weight with speed in level walking.”

Let’s see… two and a half times my body weight is 290 lbs. That means that when I walk at any kind of speed on a level surface there’s a force of 290 lbs. going to each of my hip joints with every step I take. Now, if I’m reaching forward with my stride and locking my knee, that means that that same amount of force is also going into my heels (plantar fasciitis & ankle problems), my knees (300,000 total knee replacements each year according to the NIH), my hips (you’ve seen the numbers), and lower back (The U.S. spends $50 billion each year on lower back pain). You’d think that here in the 21st century we could come up with a way to prevent some of this. Well, there is something remarkably simple that you can do the next time you find yourself walking somewhere. Are you ready for this earth-shattering piece of inside information? OK, here it is….

Don’t lock your knees when you take a step forward. That’s right. It’s pretty simple. Just make sure your knees are always bent as your foot comes down onto the ground ahead of you. Here’s how you’ll be helping your hip joint specifically. When you lock your knee the impact of your footstrike travels in a direct line from your heel to your hip because all of your bones are lined up in a straight line. On the other hand, if you bend your knees, that impact is dispersed through your feet, ankles, and knees before it reaches your hip…and the resulting impact to your hip becomes almost negligible.

Of course, if you’re used to walking with your knees locked, this means a change in what is probably a longstanding habit. Remembering to do it is the hardest part, but it is much easier to do if you can remember to always work on walking with your posture well-aligned with your shoulders and head slightly forward of where you are used to carrying them. It’s just a very slight forward tilt of your upper body whenever you’re walking.

Another way to accomplish the knee bend when you walk is to shorten your stride and quicken your cadence. You’ll sense that you’re taking smaller, quicker steps, but your legs will feel very different as will the impact on your hips and knees. It might feel a bit strange at first, but if you go back and read the statistics about knee and hip replacements and think of the alternatives…you might be more willing to watch your step.

A Cure for Foot Slapping


danny @ 10:23 am

I was recently asked, for the umpteenth time, a question that deserves a good answer.

“When I concentrate on striking mid-foot and keeping my
lower legs very relaxed, it feels and sounds like my feet are slapping the pavement much harder than before. Is this normal, or does my form still need correcting?”

For many first-timers to ChiRunning, learning to run with a midfoot strike is a very new experience. The new way your feet touch the ground, along with a distinctive full-bodied tilt can take a little time to get used to. What happens for some folks who are working on a midfoot strike, is that they notice their feet tend to slap the pavement more then they used to. If this happens to you it’s a sign that you’re on the right path to getting a midfoot strike, but it’s also a sign that there’s more work to do in other areas of your stride.

Here’s what I mean. Most people are used to swinging their legs forward when they take a stride…whether they’re walking or running. What this does is create a heel strike where your heel then becomes a fulcrum and your foot slaps down onto the pavement with each step. Not only is a heel strike unhealthy for your knees, the slapping can bruise the metatarsal heads and make your feet feel like they’re on fire.

In the ChiRunning and ChiWalking techniques, the foot strikes under your center of mass in a midfoot strike. This eliminates a heel strike and shortens your support time. The legs are always swinging to the rear, which noticeably reduces the amount of impact to the knees. When many people first try the midfoot strike they tend to focus more on the landing than on what the rest of their body is doing. The way to get rid of the slapping is to work on your pelvic rotation, which is mentioned on pages 179-180 of the ChiRunning book, and also mentioned at the top of page 82. In the ChiWalking book it is explained and illustrated on page 87.

As your foot hits the ground under you, your leg begins its rearward swing. Your leg then extends out behind you and when your foot returns to its original support position, it’s underneath you again…not landing out in front of you. As long as your foot never lands in front of your body, the slapping will go away.

Here’s the trick. Every time your leg swings out the back, let your hip swing back with it. This will force your hips and pelvis to rotate in the direction your rear leg is swinging, creating a healthy twisting motion along your spine. Your stride will open up behind you, as it should, and you’ll experience a new sense of smoothness in your gait because your legs will no longer be swinging forward which causes foot slapping.

Happy Trails,
Danny

Make the Choice to be Injury-free


danny @ 3:26 am

Being able to walk or run injury-free doesn’t happen by accident… and believe it or not, neither do most injuries. Although there are many people out there who are naturally talented in running and walking, there are very few people who never get injured. Even the best fall prey to training mistakes or momentary lapses in their technique. We’re all human and therefore subject to everything that entails, which means we spend our lives dealing with the consequences of our choices whether they’re made consciously or unconsciously.

Making the choice to live a life of injury-free running or walking involves making efforts to observe what you’re doing so you can lower the odds of being sidelined for any reason. You can choose to be injury-free by doing everything in your power to run or walk in a way that won’t hurt your body.

This choice applies to injury-prevention as well as injury-recovery. Whether you’re intent on avoiding injury or whether you want to recover from an injury, make the choice to run and walk as efficiently and as biomechanically correct as possible and you’ll carry with you the best health insurance policy there is…for the rest of your life.

The choice to be injury-free begins with self-observation. Listen to your body. Do you “hear” complaints from any body parts, in terms of aches or pain? Whenever you do, ask yourself the simple question, “Why is this happening?” Many possible answers will come, but keep asking that question until you discover the true source of the problem. Many times injuries are layered and the primal cause is not clear at first. But if you keep asking your question at each successive layer, you’ll eventually get to the origin. And when you do, you stand in the unique position of being able to choose to rid yourself of the problem forever by addressing the real cause.

When you feel that you’re onto the answer to your question, you can either refer back to the ChiWalking book or the ChiRunning book, or go to the library of articles on our website to see which focuses you can apply to correcting the problem.

Here’s where choice comes in. Once you know what it is you need to do, make a choice to instate the corrective focus(es) with every step you take until the problem goes away. Your ability to move forward into health lies in your ability to be relentlessly mindful in your movement. This is the true nature of mind-body work. Making the choice for health requires constant focus… but think of the alternatives.

Namaste,
Danny
