The density of the bentonite particles. calculated from these data is 2.457 _+ 4 x 10 -7 g/cm 3. and the compressibility is 0.12 x 10 -12 _+ 2 x 10 -20. cmZ/dyne. The +_ values are asymptotic standard errors.
The bottom line is this: You burn fat and build cardiovascular fitness at both low and high exercise intensities. The logic is that at lower heart rates you burn more fat. At higher heart rates you supposedly burn less fat but get a better cardio workout. This is partly true, but let's take a closer look. For a 20 minute workout performed at a lower heart rate, you burn proportionally more fat as a fuel source, but fewer overall calories per unit of time.
Fat Burning Zone. Your target heart rate for fat burning is approximately 55 percent to 70 percent of your maximum heart rate. Multiply your MHR by 0.55 to get your lower level threshold, and multiply your MHR by 0.70 to get your upper level threshold.o, if you are 40 years old, your estimated maximum heart rate is 180. Keep in mind that this method is based on an estimated maximum heart rate. Your actual maximum heart rate may vary slightly from this number. Your target heart rate for fat burning is approximately 55 percent to 70 percent of your maximum heart rate.
