What is a single word which can properly describe age, height, weight, and BMI?

I am completing a final assignment for a statistics course, and need a single word to describe age, height, weight and BMI (body mass index).

The best I've been able to come up with so far are physical characteristics which isn't actually a good explanation for those terms, characteristics by itself, and traits, neither of which fit very well in the title:

The Effect of NFL Players’ __________ on Skill.

Solution 1:

Biometrics is the measurement and statistical analysis of people's physiological and behavioral characteristics.

Biometrics refers to metrics related to human characteristics. Biometrics authentication (or realistic authentication) is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance.

Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. Biometric identifiers are often categorized as physiological versus behavioral characteristics. Physiological characteristics are related to the shape of the body. Examples include, but are not limited to fingerprint, palm veins, face recognition, DNA, palm print, hand geometry, iris recognition, retina and odour/scent. Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to typing rhythm, gait, and voice. Some researchers have coined the term behaviometrics to describe the latter class of biometrics.
