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.
Different physical activities cause the heart to beat at different rates. Moderate physical activity corresponds to a heart rate of 50 to 60 percent of maximum, or 93 to 157 beats per minute for a 35-year-old. Increasing your heart rate to 60 to 70 percent of maximum improves cardiovascular endurance and burns fat.oderate physical activity corresponds to a heart rate of 50 to 60 percent of maximum, or 93 to 157 beats per minute for a 35-year-old.
