Hello, can someone help me withthese questions? Describe how the Body Volume Index system works and give any 2 reasons why this type of measurement is an advantage over traditional BMI measurements.

Also , why is the BMI measurement still used widely today? What other simple measurement could be done, alongside of the BMI measurement, to assess a person's risk for cardiovascular disease, and how might a long distance runner's body composition differ from that of an elite rower? Please give me one additional reason why calipers (skin fold measurements) may not be the most reliable way to measure body fat?
