Repeated brain stimulation sessions were followed by reported leg strength gains
A randomized study reported improvements after repeated stimulation, but the abstract leaves the size of those gains and the underlying comparisons unclear.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Repeated sessions were followed by significant improvements in explosive and maximal strength in the 2 mA and 3 mA groups, with gains persisting at follow-up. A single session did not demonstrate an acute improvement in explosive strength or maximum knee torque. The abstract does not specify whether the reported gains represent advantages over sham stimulation.
The abstract provides no effect sizes, confidence intervals or explicit comparisons behind the reported improvements. This abstract-based account therefore cannot establish the practical size of any benefit or whether one intensity performed better than another.
How strength was measured
Researchers measured jump height and peak torque at the knees and ankles. Testing covered baseline, the immediate response to the initial session, the period after repeated sessions and a later follow-up assessment.
Interpreting the reported pattern
The abstract describes significant gains after repeated treatment at the higher intensities. It does not report a direct comparison between those intensities, and the single-session result leaves uncertainty about whether an acute effect exists.
