Here’s a nice piece in the Fashion & Style section of Thursday’s (4/17/08) New York Times.  The article details the training regimen of  Sara Hall and the evolution of her preferred race from the 5K to the 1500 meter.  She hopes to compete in this summer’s Olympic games in China.

Money quote:  “The most common mistake” that recreational runners make, (her coach Terrence) Mahon said, “is running the same pace all the time.” Occasionally making yourself run fast, he said, “is the only way to make yourself a fast runner.”’

Interval training is crucial to improving your performance in most sports.  Read the whole article here.

This article from Gina Kolata of the New York Times discusses the measurement of heart rates while training and “maximum heart rate.”

I’ve always been a strong supporter of wearing a heart monitor, particularly when you first start working out and when you are doing interval training.  The monitor can provide a significant aid to your workout since it gives you an immediate and unbiased view of how hard you are working.  I’ve also always thought that the monitor is extremely useful in gauging recovery, which measures your overall  fitness.  For example, if your exercise regime brings your heart rate near your maximum and then you stop and rest, it’s important to see how long it takes your heart to return to more normal levels.  If, after a minute of rest, your heart rate is still severely elevated and has only dropped a few beats that is definitely not a good sign for your fitness level.  Use of a monitor is particularly necessary in interval training, which many experts feel is the most effective type of conditioning.  It allows you to precisely track the cycle of your heart rate and lets you know if you need to push harder or less hard during an interval.  The monitor is also extremely useful as it provides your resting heart rate, a measure of fitness worth knowing.

While I’m happy to see an article that discusses heart rate monitoring during exercise the article loses some of its focus by worrying too much about one’s absolute maximum heart rate—after all, it can vary significantly from person to person and may not be a great indicator of fitness, per se.  The article  also throws in an anecdote of a person with a maximum heart rate of 400 which no doubt just serves to confuse readers.

Some of the key points from Ms. Kolata’s article:

The maximum heart rate reached may vary by sport.  For example, swimming tends to produce a lower maximum heart rate than sprinting.

Nerves can affect heart rates.

The heart monitor allows you to keep track of exercise intensity to meet performance goals or improve.

Ms. Kolata’s article drew a wide range of animated comments from her readers:  Many of the comments that  readers posted on the NYT site were excellent.  Some excerpts:

Resting heart rates may be more important than maximum heart rates, with lower being better.  (Normally, “a trained athlete” has a resting heart rate of 40-60.)

“I’m a personal trainer and I’ve been using a heart rate monitor for at least twenty years. I won’t train a client without one. When I design a workout regime for a client, one of the most important ways for the client to comply is to understand what’s going on with their body. I want the client to push themselves within boundaries and the heart rate monitor allows this. I also teach people to see how long it takes the heart rate to return to lower levels. What I have found fascinating is that perceived exertion is not necessarily a good gage of true exertion.  Most people at the gym on the equipment are working at such low rates that they might as well be taking a walk in the park. They don’t know this since they have no idea what heart rate training really is.”

“Think of an HR monitor as a tachometer which allows you to understand your own “power” usage and help endurance by keeping a pace slightly below your anaerobic threshold.”

“The correct Maximum HR can best be obtained in a sports med lab or in a real world sprint/ride, but for the recreational rider/runner/exerciser, the 220 minus age formula is a good start.”

“Notably, endurance athletes alternate intense workouts with lighter “recovery” days; HR monitors are at least as useful for exercising control on those days, keeping HR below a certain point, as they are for making sure intensity level is high enough during intense workouts.”

“Likewise, they are useful for pacing “long slow distance” runs and monitoring recovery during interval workouts.”

“Also, note that max HR is personal, and yes, it’s generally not an indication of ultimate cardiovascular capacity, and further, it’s testable! It’s probably a good idea for anyone who pays attention to HR in the health club to learn what his or her max HR is. See any of the good HR training books for advice on how this is done.”

“By basing my speed off of heart rate, I noticed that I covered more ground on each long run over the same time period, and have gotten all-around faster.  I agree that heart rate may not be the most important for everyone, but it certainly has helped my aerobic fitness and keeps me from overtraining on days when I don’t need to push myself to exhaustion.”

“Recovery time is not something that the general public should ignore. I am neither a pro or competitive athlete. But I do cycle a lot. If you are older or you do a lot of intensity and/or volume, you should pay attention to recovery time.”

“By simply cycling your intensity up and down (interval training) so that your heart rate repeatedly approaches, crosses and then drops below your anaerobic threshold, you can achieve dramatic fat-burning results, both during exercise and while you’re going about your daily business.”

“Before beginning to use a heart rate device 10 years ago, my exercise sessions and recovery were inconsistent. Knowing the zones, the heart rate, and following a program that works for me, I feel better, sleep better and am more confident that my exercise plan works.”

It’s a typical of the power of the internet that many of the comments on the original article provided more depth of understanding and detail than the article itself.  Be sure to read them all here.

I've mentioned before that I am involved with a great charity called 'Books In Homes'. It's a program where children at a disadvantaged school recieve 9 books of their choice each year. It all stems from the findings that the majority of those in prison come from disadvantaged areas, and have poor reading and writing skills. Books In Homes is all about getting thee kids interested in education, so they can make a better future for themselves.

Part of the program is the book giving ceremony, where the corporate sponsor, and a role model go out to the school and present the kids with their new books.

Well last week I was invited to be the role model at Doonside Public School. To be asked to do this was humbling to say the least, given that last year they had Michael O'Loughlan (Sydney Swans), and the Govenor General!

The coorporate sponsors for Doonside Public School are MainFreight, and they had 2 representitives from their company in attendance. It must be said that Mainfreight not only provide books at Doonside, but also at many other schools across Australia and New Zealand.

The assembly was formed and there I was standing in front of all those gazing eyes. The excitement in these kids were unbelieveable! I told them my story, about my achievements and how important education has been in my life. I explained how cool physics and biomechanics can be (Did I just say that!), and gave examples of how these subjects relate to the sports they enjoy playing. I then asked around the room, to see what they dreamt of being when they are older: teachers, archiologists, marine biologists, and captaining the Australian Rugby Team, were just a few. I remember being that old, and attending a school very similar. I really didn't want to sit back down!

The assembly finished and I was given a series of 'hi fives' as I left the assembly. We went back for some morning tea with the teachers in the staff room and I hadn't had a sip of my tea, when I was challenged to a game of handball by a group of students. I was warned that they were pretty good (and that the rules change very regularly :), but I remember being pretty good back in the day so took my suit jacket off and headed down to the 'arena'. There were 6 squares, with a line up of about 15 reserves, and apparently this is what it is like at every break. Well I held my own, but was certainly given a lesson by a couple of the older boys (Lol, 11 years old!).

The kids really seemed to love the interaction and I always had at least on standing next to me telling me their story, about where they're from, what they'd like to do in the future, or why they chose the books they did. We even had one of the more troubled students following the principal around asking a series of jokes from the joke book he had just recieved (yes, they were sick jokes, and yes I laughed at every one of them!)

I am being totally honest when I say it one of the best things I've done in years. I walked into that school thinking that I had few stressful situations to deal with during that week, but left with a whole new perspective. I couldn't get the smile off my face, and there was no event in my life at the moment that was even the slightest challenge. How could I think otherwise after seeing these kids, and the joy they had at just recieving these books?

Now I know these kids will go back to their normal lives, some probably have minimal love and supervision, or not even the essential 3 meals a day. But now they have these books, and I have no doubt that there will be some in that group that will one day look back on the Books In Homes program, and wonder where their life might've ended up without it!

I can't wait to go back!
