What percentage of a typical body is composed of lean tissue?
a. $50-60 \%$
b. $75-85 \%$
c. $60-70 \%$
d. $85-95 \%
Answer (2)
The typical percentage of lean tissue in a human body is best represented as 75 − 85% , as this range includes the muscles, bones, and organs, making it a realistic composition for healthy individuals. Therefore, the answer is option b: 75 − 85% .
;
Analyze the definition of lean tissue, which includes muscles, bones, and organs.
Evaluate each percentage range to determine which is the most plausible for the proportion of lean tissue in a typical body.
Select the option that represents the correct percentage range.
The percentage range of lean tissue in a typical body is 75 − 85% .
Explanation
Understanding the Problem The question asks for the percentage of lean tissue in a typical human body. Lean tissue includes muscles, bones, organs, and other non-fat components. We need to choose the most reasonable percentage range from the given options.
Evaluating the Options Let's consider the options:
a. 50 − 60% : This would mean that fat makes up 40 − 50% of the body, which is high for a typical body.
b. 75 − 85% : This seems like a reasonable range for lean tissue, as it accounts for muscles, bones, and organs.
c. 60 − 70% : This is lower than what is generally expected for lean body mass.
d. 85 − 95% : This would mean that fat makes up only 5 − 15% of the body, which is very low for a typical body.
Determining the Correct Range Considering the composition of a typical body, the most plausible range for lean tissue is 75 − 85% .
Final Answer Therefore, the correct answer is b. 75 − 85% .
Examples
Understanding body composition is crucial in various fields, such as sports science, medicine, and nutrition. For example, athletes often aim to increase their lean tissue to improve performance. Doctors use body composition analysis to assess a patient's health and risk for certain diseases. Nutritionists use this information to create personalized diet plans. Knowing the percentage of lean tissue helps in setting realistic fitness goals and maintaining overall health.
