Unilateral strength training leads to muscle-specific sparing effects during opposite homologous limb immobilization

Unilateral strength training preserves strength, muscle thickness, and muscle cross-sectional area in an opposite immobilized limb. The preservation of size and strength was confined to the trained homologous muscle group. However, strength was preserved across multiple contraction types.
