Population studied: 139 healthy women in a parallel-group randomised controlled trial, mean age 71.5 years.
Dosage & Duration: 1300mg Magnesium/day for 12 weeks.
Method: Assessment of Short Physical Performance Battery (SPPB); secondary outcomes were changes in peak torque isometric and isokinetic strength of the lower limbs and handgrip strength.
Results: No difference at baseline was found between the SPPB scores of the 2 trial groups. However, after 12 weeks, the treatment group had a significantly better SPPB score, chair stand times and 4-m walking speeds. These findings were more evident in participants with a magnesium dietary intake lower than the Recommended Dietary Allowance. No significant differences emerged for the secondary outcomes investigated. Overall, daily magnesium oxide supplementation for 12 weeks seemed to improve physical performance in healthy elderly women.
