Stress Test

on Thursday, June 24, 2010 at 7:05 AM

Went for a cardiac stress test yesterday.  I also had an echocardiogram done while there.  I have to wait 2 weeks for the official report.  I tried to garner some information from the people doing the tests, but all they said was that everything looked okay. Not sure if that's what the tell everyone so as to not scare you.

My family doctor suggested the stress test after I mentioned the weird symptom that I sometimes see while running.  Here's an example from when I ran a marathon last fall. 


I started the race out fine, but at about the 2mile mark, the HR spiked for 4 miles and then returned to normal. It doesn't happen on every run and I'm not sure if there's anything that triggers it. It's a weird symptom.  I can sometimes sense when it starts since it feels like a skipped heart beat, but other than that I don't really know that it's happening unless I look down at my watch.  As far as I can tell, it impacts my performance only during shorter faster races where VO2Max becomes a limiting factor.  I think that's why I have problems with 5k races.  The harder intensity means that the HR is more likely to spike which causes a worse performance when it does. Anyhow the main objective of a stress test is to stress the heart to try and get it to do something abnormal and then analyse what the abnormal part is.

I had my echocardiogram done first.  This is where they use an ultrasound to take various pictures to get an idea of what the heart looks like and the blood flow through it.  The tech said that everything looked fine, but I'm not sure if she was the one doing the analysing or if a doctor is supposed to look at the pictures and issue a final report.

Then had the fitness test done.  They hook you up to a bunch of electrodes to get an EKG and then put you through a treadmill test at every increasing intensity while monitoring your blood pressure. The doctor asked some general questions about my HR issues and wanted to know a bit about my running. I said that I ran marathons and she then mentioned that she was a runner too and was doing her first marathon this fall in NY.  She then said that we might be here a while since the test builds up only gradually and most people will bail at some point during the test once the effort level increases.

So the test starts at a slow walking pace and flat incline.  Every couple of minutes the pace and incline of the treadmill increases and they measure your blood pressure.  I kinda figured early on that my HR was not going to spike during this test since from experience I know that if i build up the effort gradually enough, the HR will not spike and since this test was doing just that, it probably wouldn't reproduce the conditions that cause it to occur. I think I got a lot farther into the test then most people would because the treadmill started to make some strange noises at the higher speeds and the tech and doctor began to comment on it like it was a weird occurrence. The HR never did spike and the test shut down after what I'm assuming is the maximum effort level that the treadmill can induce. It could also have been that they thought i was working too hard since by the end of the test, i was dripping lots of sweat.  I'm not sure of the speed but by the end, it felt like around 8min/mile.  The incline was somewhat steep though.  My legs were starting to fatigue at the end and I was breathing somewhat hard, but not like interval hard. Afterward, they said my HR peaked at around 180 which for me is a good tempo effort when I know from past experience my max is at around 190.  In total, I think the test lasted a max of 15 minutes.

I'm somewhat disappointed by the test since I don't think the test really "stressed" me. But I can understand the reasoning for the treadmill test.  Most people that come in for stress testing have heart issues and are not involved in exercise and are usually of older age. Most of the people in the waiting room were seniors and the people who were younger seemed to be people who had brought their parents/grandparents to the office.  The test should induce cardiac stress in most people, but just not me on this particular test. 

I have to wait for the official results, but assuming that they don't report anything wrong, I will have to examine some other options as I'm still concerned about the increase in HR.  Another option which I'll have  to talk to my doctor about is a Holter test which is where you are hooked up to a portable EKG unit that you wear for 1 to 2 days.  I was actually hoping that my doctor would initially prescribe this instead of the treadmill stress test .  I think the main purpose of having the stress test done in a doctor's office is that you would have medical personal there in case anything bad happens.  The downside is that you are somewhat limited by the artificial test conditions present whereas if I used a holter device, I'm fairly certain that I could get my HR to spike under conditions of my choosing. 

Anyhow, I'll report on the results when they come in which should be in about 2 weeks.

Whitby 5k Race Report

on Saturday, December 5, 2009 at 11:50 PM

Ran this race 2 weekend's ago.  They also hold a 10k and a 10 miler.  It's a bit strange since the same location also hosts a half marathon in the the summer along with a 5k and 10k.  So i did a Whitby 5k race back in July and this race is called the same thing.  Confusing.

Long story short is I finished in 20:26 and i'm pretty sure the course was short.  It was a different route than the short 5k i ran in July, but it was still short nonetheless. Garmin measured it at 3.06 miles which is about 75m short.  Mapped it out in Google Earth and it says its even shorter than that.  As usual, i ran into HR issues.  I wore the HR monitor but put electrical tape on the readout cause I didn't want the readout bothering me during the race.  Was okay for the first 2 km which were right on pace (4:00, 3:59), started to slow down during km 3 (4:11), had a miserable 4th km (4:33) and then was able to speed up for the last km (3:40 for .58km about 3:58 pace).  Felt like crap during the 4th km.  Checking out the HR afterwards, my HR spiked just after the 2km mark and then returned to normal just before the 4th km marker which would explain the slow down in the middle of the race and the speed up at the end.  But then again, all my 5k's tend to follow this trend so i don't know if it's a result of the HR thing or not.  It would make sense though. A 5k is run at the limits of ones VO2Max and anything that can change that obviously will have a big impact on performance.  The HR monitor slid down off my chest with about 500m to go so that's what the drop in HR right at the end.

Finished 15th overall and 5th in my age group.  They gave out a nifty orange toque.  Not really nifty in the sense that I would wear it in public(maybe i'd wear it in a race), but nice to get something other than a t-shirt. They had soup and sandwiches afterwards.  They used a completely different route this year for the 10k and 10 miler.  Apparently they didn't have anyone telling people where to turn around for the 10k so a lot of the 10k'ers ran longer than they should have.  There was one woman at the finish line who was really pissed of about it and complaining to anyone that would listen.  Yikes, I just smiled, nodded my head and moved along. 

Though i didn't win any prize at the event, i received an email a few days after telling me I had won something and should send them my address.  I had signed up for Road Warrior program a while back.  It was started by the guy who organized the pace bunnies for the Scotiabnk waterfront races.  The program offers a grading system where you basically race against yourself but your improvement in times is compared to other Road Warrior participants at a given race.  They basically average your times over the past year to an equivalent 5k time and if you are able to run faster times than that you are more likely to place higher in the Road Warrior standings. In theory, this sounds great, but unfortunately it's idiots like me who intentionally run slow during a lot of races that end up screwing up the curve.  Prior to this race, the Road Warrior program had me as a 23:58 5k runner. This was due to my races at the beginning of the year when I was practicing to be a pace bunny and also due to someone who was accidentally given my bib and chip who ran a 38 minute 5k back in June. So when it comes to race day, and I'm able to put down a 20-something 5k, the program thinks I had a great improvement and ranks me high.  Very easy to game the system.  I didn't respond to the email asking for my address cause it felt like I had cheated and didn't deserve the prize which was a pair of socks. 

I was contemplating trying another 5k before years end, but I have a blood donation appointment next week which when combined with the fact I haven't run in two weeks means I'm probably not going to be in racing shape before the new year.  I guess, it'll just have to be another goal for the new year.

Sleepy HR

on Thursday, August 13, 2009 at 8:22 PM

Yes I know I'm weird and a nerd.  I wore my HR monitor to bed last Friday and did again last night.  I wanted to get an idea of where my resting HR is these days.  I did this a couple of years ago and it was about 45.  Based on the graphs, it seems to be at 43 today.

 
Friday
 
Yesterday
I only ended up wearing it for about 3 hours each time.  I wasn't sure if the 43 was right last Friday since I thought it would be lower, so I decided to do it again.  I had intended on wearing the monitor the whole night, but I woke up unexpectedly after about 3 hours and decided to just take it off to save some of the battery.  There were times the HR dropped into the lower 40 and even into the high 30's but i think 43 is the more consistent HR when it wasn't spiking on both days so that's probably what the HR is.  I'm not worried about the HR spiking parts.  The HR only jumped for very brief moments and i've been reading the HR can fluctuate during the night depending on one's breathing pattern and what stage of sleep one is in.

Looking at HR

on Thursday, August 6, 2009 at 10:50 PM

Gotten all my runs in for this week as planned. Thought I would document some HR stuff.

Tuesday: Did a little over 10 miles with 5 miles at LT pace. Averaged 7:04 pace for the LT portion. Did them around the track. It was about 20C in the morning to start and it was a struggle to roll out of bed in the morning to get this done. I'm sort of disappointed with the pace on this. I had thought I would be able to maintain this consistently below 7 min/mile especially on a flat track, but I think the relatively warm weather kept me from being able to hold the right pace. The effort felt harder than the 5 mile LT run I did last week on a non-flat route yet the pace was slower. The HR stayed below 180 which is where I like to keep it for LT runs, but don't like that the HR was constantly increasing throughout the LT portion. I normally like when it reaches 180 and then stays there for the entire run as it basically means that it's sustainable. Now it could just be that 5 miles was too short to see the plateau effect and the warmish weather may have contributed to it cause I was sweating buckets towards the end so who really knows.

Wednesday: Did 4.1 mile recovery run at 8:52 pace. It was relatively cool for this run at less than 15C. HR for recovery runs I've always tried to keep below 150 and a pace of no faster than 9 min/miles. I had no trouble keeping below 150 and it was lower than 140 at times. Pace however was 8:37 which is a bit too fast. If it wasn't for the slow first mile done at 9:26 pace, the average pace would have been much faster. I was comparing this to the HR during the Ottawa marathon where I was doing 8:45 pace but my HR was in the high 160's. I am in much better shape than I was back then.

Thursday: Could not force myself out of bed in the morning so ended up doing my 11 mile run after work, but wasn't feeling the greatest. I had eaten two lunches today. Lately, I'm famished come lunch time and ended up eating at noon, only to find out that some of the co-workers were taking a visitor out to lunch at 12:30. Not wanting to be anti-social I joined them with the intent of only nibbling on some of the Chinese food they were ordering, but I ended up having an entire second lunch. Needless to say, I was super stuffed this afternoon and my system had not quite processed it by the time of the run so I carried the bloated feeling for most of the run. First three quarters weres done slow and picked up the pace for the last quarter. Two interesting things to note are that HR was higher though pace was slower for the first three miles then the recovery I did yesterday (it was the same three mile route). Probably due to it being warmer and me being heavier. Second, based on the data from the end of the run, I think I can maintain a sub 8 min/mile at a HR of less than 160 though I"m not entirely sure cause I didn't wear the garmin today. Will have to test out this theory on Saturday.

I've been kinda wondering what my resting HR is these days. Last year when I got my wisdom teeth pulled, the nurse said it was 37. This was just after what I would guess was my peak fitness point. A couple of years ago, I wore my HR monitor to bed and it was 45 (i know I'm weird). I'm going to try wearing it to bed tomorrow to see what it is. I'm guessing probably around 40.

Crunchy Snow

on Friday, January 26, 2007 at 9:28 PM

So I didn't get around to doing the 10 miles I had planned for yesterday as I couldn't get up in the morning and it was too cold and too late when I got back from work last night. Since it's the first week of marathon training and I really didn't want to have to report that I was skipping runs during the first week, I decided to to do it today. The temperature was -18C degree outside this morning. Really cold, but thankfully there was no wind.


Lap Lap Time
1 09:19.50
2 09:14.60
3 09:15.70
4 09:54.00
5 10:10.70
6 09:17.80
7 09:32.60
8 08:53.50
9 08:38.60
10 08:54.80

HR is still up, but it's coming down a little. The 10 min/mile were around a slightly snow covered track. I like the sound of snow crunching under my feet as I run. It has an almost hypnotic sound to it and gets me to zone out at times. I'm also finding that running on snow and ice forces me to be more efficient with my running. It should pay off when the spring time rolls around.

Though I was generally warm while running, I think I have to buy something to cover my face if I'm going to keep running outside in temperatures like this since my face was dry and chapped when I got back.

I'm going to try and do 4 mile recovery tomorrow morning and a 14 mile long run on Sunday.
