Strength gains by motor imagery with different ratios of physical to mental practice

M. Reiser, D. Büsch, et al.

Explore the groundbreaking study on motor imagery in strength training conducted by Mathias Reiser, Dirk Büsch, and Jöm Munzert. Discover how incorporating imagined contractions can yield significant strength gains while potentially reducing the need for high-intensity workouts.

Abstract
This study investigated the effectiveness of motor imagery (MI) in strength training. Four groups underwent a 4-week standardized strength training program followed by a 4-week intervention: a control group (CO), a group with MVC (maximum voluntary contraction) only (MO), and three groups combining MVC and imagined maximal isometric contraction (IMC) training at different ratios (M75, M50, M25). Results showed that IMC groups had slightly smaller but still significant strength gains compared to the MO group, and significantly greater gains than the CO group. Strength gains were maintained after a week of rest. The study concludes that high-intensity strength training can be partially replaced by MI without significant strength gain reduction.
