The transfer of strength from a trained limb to an untrained one is a well-known phenomenon, thought to be due to neural adaptations, and offers potential benefits for athletes seeking to maintain strength in an injured limb while it is out of action. But does this apparently miraculous transfer of strength affect both sides equally? Probably not, according to a team of Canadian researchers, who studied transfer of arm strength in right-handed people and found it operated only from right to left – ie from the dominant to the non-dominant side.
Thirty-five strongly right-handed women were randomly assigned to left-hand training, right-hand training or non-training (the control condition). The strength training consisted of a high intensity handgrip exercise, four times a week for six weeks. Peak torque, muscle thickness and muscle electrical activity were assessed before and after training in both limbs.
