Hazards of Running and Walking While Angry

by Kirk Mahoney, Ph.D. on June 17, 2010

Many runners and walkers, especially those who train for and participate in endurance races, know about the psychotherapeutic effects of running and walking. So, it makes sense to many people that going for a long workout could be a good way to recover from anger. While it is true that the time to reflect and the eventual endorphin rush could pull you out of your anger, the hazards of exercising while angry outweigh this benefit. Here are five of those hazards.

1. Anger while working out can program you to reduce or eliminate training.

When you exercise while angry, you program your unconscious mind to associate it with this powerfully negative emotion. But your unconscious mind is always working to protect you from pain, even if it does so in destructive ways. This means that your unconscious mind will try to protect you from the pain of anger, which you may have associated with running or walking. So you will reduce or eliminate that exercise — probably the opposite of what you wanted when you went for a long run or walk to “work out” your anger.

2. Anger while working out blinds you when you have to be your most cautious.

It is a classic story in books and movies because it is true. A story’s character becomes angry, goes out for a drive, and crashes his or her car because of failure to notice danger. Many running and walking situations entail safety hazards. Working out while angry means that you will be less alert to these hazards, which means that you increase your likelihood of getting into an accident.

3. Anger while working out easily leads to chronic injuries.

Anger can cause you to push yourself too hard during a workout. And pushing yourself too hard can easily lead to iliotibial-band strains and other injuries that can require long-term physical therapy for recovery.

4. Anger while working out drives away good training partners.

Even the best training partner does not want to train with you when you are angry. If you feel this way very often while exercising with him or her, you very likely will drive your training partner away.

5. Anger while working out attracts other angry runners or walkers.

The Law of Attraction works just as well, if not better, for negative emotions as it does for positive emotions. This means that walking or running while angry will tend to attract other angry runners or walkers. Do you really want this kind of runner or walker in your life after you have overcome your anger?

How to Run Your Races with Courtesy

by Kirk Mahoney, Ph.D. on June 11, 2010

If you know how to run your races with courtesy, then you will activate the Law of Attraction in your favor. After all, racing with other runners can be a lot of fun. But, frankly, you can be a big source of irritation to other racers when you are careless about what you are doing while racing.

Here are several ways to be more courteous to other runners while racing.

Ensure that your running shoes’ laces are securely tied.

You can create quite a hazard by stopping in the middle of a road or path to re-tie your shoes. Plus, you can trip over your own laces, if they become untied. Take some extra time before your race to be sure that your shoelaces are securely tied. Or get a lacing system that can never become undone.

Look where you toss water cups, especially half-full ones.

Although a splash of water may be refreshing to you during a hot race, the racers behind you do not want to be splashed by your half cup of water just beyond a water station. For example, water splashed onto their legs can drip into their socks. Even the best perspiration-wicking socks can not necessarily keep up with that amount of water, so you could inadvertently cause a blister in a runner whose legs get doused by the water remaining in the cup that you toss carelessly. Also, the water that you spill can be a tripping hazard on an oily road. If you cannot drink all the water, then take care to toss the cup off the race course.

Stop by the side of the road or trail to spit.

Racers do not want to be “misted” by your spit, and they do not want to step in it, either. If you must spit, then carefully run to the side of the road, stop, and spit.

Look before stretching your arms.

Shoulders and arms can get tight during a race, especially a long one. But be careful when swinging and stretching your arms. Otherwise, you could accidentally bloody or bruise a quiet runner nearby.

Look before slowing to a walk.

If you use micro-level pacing, or if you are fatigued, then you eventually will have to slow from a run to a walk. As with arm stretching, look around before doing this. Failing to do so can lead to bad accidents, with several runners on the ground.

Warn other runners before cutting in front of them.

Cutting in front of other runners can be quite dangerous, especially when they do not expect it. Say something (“Excuse me.” or “Sorry. Crossing in front of you.”), or at least motion with a hand, before crossing the path ahead of another runner.

Announce tripping hazards that lie ahead of you.

Depending on how big you are, how small are the runners behind you, and how close are the runners behind you, you can cause one or more of those runners to trip simply by failing to announce a tripping hazard that lies ahead of you on the road or trail during a race. This is analogous to a motorist hitting an object in the road because he or she was following another motorist too closely or could not see beyond a very large vehicle ahead of him or her even when following that larger vehicle from a safe distance for braking. If you are about to step around a tripping hazard, then take a moment to announce the hazard to those behind you.

Stop to talk on a cellphone.

If you must take or make a call on your cellphone during a race, then stop to do so. Just as motorists who talk on cellphones tend to drive more slowly, runners who talk on cellphones tend to run more slowly. And this speed differential with fellow runners can be dangerous. Do the courteous and safe thing by running to the side of the road or trail, making sure that nobody is immediately behind you, and then stopping to make or take that call.

Do not race with stereo earphones.

Stereo earphones are banned from many races because of the hazards that they create as clueless racers miss announcements from race officials, emergency responders, and fellow runners. Race without earphones. Or, if you feel that you absolutely must have your own personal music to accompany you, then race with an earphone in only one ear, so that you can keep the other ear open for your race environment.

Do not run backwards unless you have a lot of room.

You may want to run backwards to work out a kink or when trying to face another runner whom you want to motivate. But do this only when you have a lot of room and see no hazards further down the race course. Otherwise, you may run backwards into another racer. Or you may fall and cause one or more of the runners who you were facing to trample and fall over you.

Avoid wearing costumes that interfere with vision or running.

Costumes on runners often draw laughs and cheers from spectators and other runners alike. But be careful what you wear. Avoid costumes that could obscure your vision or that could trip you.

Avoid running two or three abreast.

It can be a lot of fun to race side-by-side with a training partner or two. But realize that this can create a “wall” that blocks runners behind you from passing all of you. The solution is simple: Leave a space that can let at least one runner pass between you and your training partner.

Means Are Not Enough

by Kirk Mahoney, Ph.D. on June 2, 2010

If you keep a running log (which you should do), then one of the things that you may like to do with it is to compare your average pace in one training season to your average pace in another training season.

For example, suppose that you followed an identical running schedule in training seasons A and B, with season B following season A but with some sort of boot-camp, cross-training, or gym workouts coming between seasons A and B. And suppose that you had a mean pace of 11:05/mile in season A and a mean pace of 10:55/mile in season B.

Would it be fair to say that there is a statistically significant improvement in your mean pace in season B in comparison to season A?

After all, the supposition is that season A had an 11:05/mile mean and that season B had a 10:55/mile mean — an improvement of ten seconds per mile!

Unfortunately, it is not enough to look at two means and say that one is statistically different than the other.

Of course, season B’s mean pace could be better than season A’s mean pace in a statistically significant way. But we cannot tell from looking at the means alone.

The path to statistical significance requires us to know how many values went into each sample mean and to know the variability of those values.

  • The sample means from seasons A and B in this scenario would be written in statistical notation as x-bar-subscript-A and x-bar-subscript-B, respectively.
  • The “how many values” part is easy to identify in this scenario. It is simply the number of running workouts on the running schedule. Written in statistical notation to refer to seasons A and B, these two numbers would be written as n-subscript-A and n-subscript-B, respectively. And, because we originally supposed that you followed exactly the same schedule in those two seasons, we also have that n-subscript-A equals n-subscript-B, which equals the total number of runs prescribed by the schedule.
  • The “variability of those values” part is calculated as what is called the sample standard deviation and would be written in statistical notation as s-subscript-A and s-subscript-B for seasons A and B, respectively. You can search the Web for information on how to calculate a sample standard deviation. And some computer spreadsheet programs will calculate this for you.

With the sample means, sample sizes, and sample standard deviations in hand, you can calculate what is called a “two-sample t statistic” (the formula for which is taught in many textbooks and on many websites) and determine from this calculation whether season B truly was better than season A at a specific level of statistical significance (such as 95%).

Why People Choose Running

by Kirk Mahoney, Ph.D. on May 26, 2010

If you consider yourself to be a runner, have you ever contemplated why you do it? If you do not consider yourself to be a runner, have you ever wondered why people choose running?

No matter whether you consider yourself to be a runner or not, it can be worth examining why you should run. If you already are a runner, then the following list may renew your drive to run. If you are not yet a runner, then the following list may make you into one. (You have been warned!)

I run for people.

  • I run to set a good example for my children or grandchildren of taking care of one’s health.
  • I run to stay alive long enough to see my children or grandchildren graduate from college, get married, and start their own families.
  • I run to raise funds for those less fortunate or afflicted by a disease that needs more research to find a cure.

I run for places.

  • I run to visit more cities as I participate in races across my own country.
  • I run to visit more cities around the world, each with its own exciting race and new things to teach me about how people live and how we are all alike.
  • I run to raise funds for cities and countries devastated by wars, famines, and natural disasters.

I run for things.

  • I run to get from my races their colorful technical shirts that I can wear with pride.
  • I run to collect medals that I can wear at work right after a race and can hang with pride at home.
  • I run to buy training gear that helps me to protect myself and helps me to improve my performance, so that I can run even more.

I run for experiences.

  • I run to meet new people, see new places, and try new things.
  • I run to experience new tests of my physical endurance.
  • I run to stretch my mind, to experience new tests of my willpower, and to expand my mental fortitude.

Most of all, I run for joy and happiness!

  • I run because running has to be one of the healthiest and fastest ways to trigger feelings of joy.
  • I run because I love the feeling of being in a competitive race, surrounded by others who enjoy this feeling, too.
  • I run because the joy of training for months for a race brings me long-term happiness like no other endeavour.

Why do you run? Please leave a comment here. Thanks!
