Comparison of Cross-Education and Global Training Effects in Adults and Youth After Unilateral Strength Training

The objective was to compare adult and youth cross-education and global training effects on dominant and nondominant limb testing. Initially, 15 men and 15 prepubertal boys volunteered for each unilateral chest press (CP), handgrip training, and control groups (n = 89). Individuals trained their dominant limb 3 times per week for 8 weeks and had their dominant and nondominant limbs tested for CP and leg press 1 repetition maximum (1RM), handgrip, knee extension and flexion, and elbow extension and flexion maximum voluntary isometric contractions (MVICs). Adult CP training gains were significantly greater than youth with lower-body testing (p = 0.002–0.06), whereas youth CP training gains exceeded adults with upper-body tests (p = 0.03–0.07). Training specificity was evident with greater CP 1RM increases with CP vs. handgrip training for both youth (p
