Compared with resistance training alone, adding amino acids improved grip strength (SMD 0.69), gait speed (SMD 0.64), Short Physical Performance Battery scores (SMD 1.69) and sit-to-stand time; skeletal muscle mass did not change. Certainty was low to very low.

Walking speed rose in all intervention groups, but leg muscle mass rose only in the exercise groups and knee strength only with exercise plus EAAs (9.3%); EAAs alone did not raise muscle mass.
