Strength is neuromuscular
Producing force requires muscle tissue, but also effective neural activation and motor-unit coordination.
Weakness is not automatically sarcopenia
Sarcopenia has a specific diagnostic framework. Subjective weakness can have many explanations and must be interpreted in context.
Measure and train function
Direct strength tests and functional tasks such as chair rise provide complementary information, and resistance training has a strong evidence base.
Established evidenceFactual statements are grounded in the publications listed below.
KŌMØ perspectiveKŌMØ favours a multidimensional, longitudinal reading of mobility.
