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.
Pushing your body to exercise at a very high heart rate makes you burn more calories, this is true, but not so many from fat. For example, exercising at 90% of your maximum heart rate will burn only around 15% of calories from fat.raining at higher heart rates burns more calories, there's no doubt about it, but a smaller percentage comes from fat burn. For example at 80% of your maximum heart rate 50% of the calories you burn come from fat.
