Abstract
The study by Jerez-Mayorga et al. (2020), published in Physiology & Behavior, investigates the reliability and relationship between muscle quality and strength in elderly women. Results showed that Functional Electromechanical Dynamometry (FEMD) is a highly reliable tool (ICC = 0.95–0.98) for assessing muscle status. It specifically highlights the Muscle Quality Index (MQI) as a critical indicator of functional status.
This research advocates for the use of the MQI alongside traditional strength tests to identify older adults at risk of functional decline. By accounting for the quality of the muscle rather than just raw power, clinicians can provide more targeted and effective interventions.
