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.
How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.Medications and some medical conditions may affect how fast your heart-rate is at rest and with exercise.ou can tell how fast your heart is beating (your heart rate) by feeling your pulse. Your heart-rate is the amount of times your heart beats in one minute.
