Once you know the BPM you should be running to, you can find the right music and create the ultimate playlist to help you maintain a steady rhythm for your runs. You could also switch up the BPM playlists if you want a more intense run (166 BPM, for example) or an easier jog (150 BPM).
In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body. For many clinical purposes BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.
Average body surface area for children (12-13 years): 1.33 m2 Body surface area is used for a determining other medical measures. As examples, renal function is measured by the glomerular filtration rate (GFR) which is calculated in regard to the body surface area.
