title: The effect of vitamin B12 on physical performance capacity.
abstract: 1. Physical performance capacity was assessed before and after injection of cyanocobalamin and a placebo for thirty-one Burmese male subjects whose age ranged from 18.7 to 20.8 years. 2. The subjects chosen were free from anaemia and were paired on a "weight--age" basis and divided into two groups. 3. One group received an injection of 1 mg cyanocobalamin and the other was given a placebo injection three times weekly for 6 weeks. This was done on a "double-blind" basis. 4. There was no significant difference between the two groups in any of the criteria measured, before and after administration of either 1 mg cyanocobalamin or placebo injection. So also there was no significant increase in any of the measurements in the subjects after receiving cyanocobalamin injections compared with thosse receiving the placebo.
