Is lower limb muscle power by vertical jump a sensitive and specific measure for screening sarcopenia compared to handgrip strength and chair stand test?

Key Points

• Lower limb muscle power from vertical jumps is a notable indicator for sarcopenia screening.
• Muscle power assessment demonstrates sensitivity and specificity superior to handgrip strength among older adults.
• The analysis involved comparing multiple tests—vertical jump, handgrip strength, and chair stand test—across diverse demographics.
• These findings may enhance early detection strategies for sarcopenia prevention and management in aging populations.
