Listen to Your Heart, but WATCH Your WATTS!!!

Take a look at this chart. We've got a good workout from Paul Dybala, a client at the White Rock Lake location. What's interesting is that if you look at the red line, which displays heart rate, you'll see a minimal trend of rising intensity, but it sort of plateaus, both on range and max/min for each interval. However, if you look at the Watts, in light blue, well, it goes UP, and UP, and UP! But HR doesn't show you that. 

For decades, Heart Rate was viewed as the primary indicator of fitness. Zones were developed, based on good science, to indicate levels of intensity and fitness results. But with HR, intensity was just too vague to account for quantifiable values. Again - look at the chart. Heart rate range between intervals was pretty similar each time, and yet, wattage went up - significantly. Not even cadence changed all that much for the intervals themselves.... 

What does it all mean??? Well, for one thing... While you can get a good idea of your workout intensity from Heart Rate... you'll get a more acute sense of your work, with Wattage. Secondly - while Heart Rate Monitors can be purchased for around $50, Wattage meters, which WERE once in the stratosphere in terms of cost, continue to decline in price, while remaining both accurate and consistent. This image shows the successful merge between the Physics of Wattage, and the Physiology of Heart Rate. You can't have one without the other, but it's the Wattage that determines the success of your workout - with heart rate alone, you're just not getting the full picture. 

Stay tuned, though. Cycling Center Dallas is working with a MoxyMonitor, to measure Muscle Oxidation levels and Total Hemoglobin, which, when combined with wattage, will yield a TRULY complete picture of the cyclist, inside, and out, in real-time.
