|Heart Rate Question.||Len J|
Aug 22, 2002 5:52 AM
|I use a heart rate monitor in all my training. As a result, I have gotten pretty knowledgable about how my body reacts to different workouts/winds/speeds etc. Normally, doing a pull in a paceline at 23/24 mph on flat ground with little wind requires a heart rate of somewhere between 170 and 175. My Max is 200 and my LT (tested via TT) is 180. Last night, in a group ride, doing the same pull had my heart rate between 184 & 188. In addition, we were doing 4 minute pulls & my legs were fine, little if any lactic burn, legs felt like I could have kept pulling at this pace for a while.
I don't get it. My body is telling me something, I just don't know what. I have about 5,500 miles this year, 3,500 of it base (Zone 2 miles). I am currently riding around 160 miles/week in 4 workouts. I do one to two inteensity workouts/week (Usually one) so I don't think or feel like I am overtrained. I came off my firsst peak the end of June, rested for 2 weeks and have just finished 4 weeks of base 3 and am in week one of Build 1 for a second peak in October. All of my testing shows that I am right on track until this week. BTW, I did a long endurance ride on Saturday and had a problem keeping my Heart rate down in the last hour. At the time I believed that I simply overheated (Heat index was 110) so I simply shut the ride down & spun home. Now I wonder if the two are connected.
Any of you psyiologists (SP?) have any explanation for this?
Thanks in advance.

|Heart rates are subject to a lot of variables. Don't hurt your head trying to figure it out.
I used a HRM for years, kept logs and charts (percieved effort vrs actual, air temps, diatance-charl after chart after chart). I concluded that I didn't know anything.

|I have just started using a HRM, so can't help you there. But, with all the high temperatures and humidity we have been having this summer in the Southeast, I really notice it. I got the HRM after my heart started racing after several days of long, hard rides in the heat. The heat this year is really exceptional. In Raleigh, we've had 60+ days over 90 so far and could very well top the all-time record set in 1942 (73 days) by the time it finally cools off this fall.|

|That's what I thought on Saturday but last night was almost plesant. I've ridden in worse with no effect.

|The heat this summer has been relentless. On "cool" days, it only hits the low 90s. I think the cumulative effect of riding in the heat has an effect. I had a full-scale leg cramp in my thigh a couple weeks ago -- even after drinking 3 bottles of Gatorade during the ride -- the first time that has ever happened to me.|

|There are lots of variables, some of which we probably don't even have an explanation for. However, you'd only worry about recovery if you couldn't get your heart rate up while at the same time you have no zip in your legs.|

|Like someone said - too many variables - sunds like the heat is the most likely - the only way your body can cool itself down is by pumping more blood around so your hr will go up.
Could be dehydration too - same thing actually - the lower water content of the blood decreases it's cooling affect so your heart pumps more of it.
Or you could have a viral infection - a mild one. If you're going to use a hrm you should pay close attention to your morning resting hr. If it's up by 10 beats you're infected. (We're all infected by about 20 different viruses/bacteria at any one time - sometimes one a growth spurt going and makes your immune systwm work a bit harder - so your heart rate goes up.
p.s. I'm a biochemist (Dr.) - does that count?
