Muscle Strength Pilot Study Protocol:

Eligibility: Sample persons aged 6 years or older are eligible for the Muscle Strength Pilot Study.

Informed Consent: Informed consent will be obtained as a part of standard NHANES consenting procedures. For paid volunteers, who are not NHANES participants, written consent will be obtained.

Exclusion Criteria: The exclusion criteria for this component are as follows:

For handgrip test: had surgery on hands or wrists in the past 3 months.

For lower body strength test: have amputation of both legs.

Study Design: The proposed muscular strength measurements include two tests in the MEC: 1) a handgrip dynamometer assessment will be used to assess upper body strength, and 2) a lower body (quadriceps/hamstring) strength assessment using a dynamometer placed at the lower shin of the participants.

Data Collection: NHANES participants will take the assessment in a NHANES Mobile Examination Center (MEC) room. Paid volunteers will take the assessment at the NHANES Home Office. These volunteers will be remunerated $25.

Report of Findings: Results will not be reported to the participant.
