Concurrent activation potentiation (CAP) enhances lower body torque and rate of force development, via the contraction of muscles remote from the prime mover. This study assessed the effect of remote voluntary contractions (RVC's) on upper body muscle activation and force. Fifteen women (20.7 ± 2.1yr) and fourteen men (21.4 ± 1.8 yr) performed isokinetic concentric elbow flexion and extension at 60 degrees/sec for 3 repetitions in RVC and NO-RVC conditions. The RVC condition included jaw clenching, plantar flexion, and the Valsalva maneuver. Rate of torque development (RTD), peak torque (PT), and average power (P) were assessed using dynamometry (System IV, Biodex Inc., Shirley, NY). Electromyography (Myomonitor IV, Delsys Inc., Boston, MA) was used to assess activation of muscles potentially involved in the RVC's (gastrocnemius, rectus femoris, hamstrings belly, rectus abdominous, flexor digitorium superficialis, masseter) and the prime mover and its antagonist (biceps brachii, triceps brachii). A two way mixed ANOVA with repeated measures for test condition was used to evaluate the interaction between RVC/NO-RVC conditions and gender, and to assess the main effects. Significant main effects were further evaluated with a paired samples t-test. Significant main effects were found for RVC/NO-RVC condition (p ≤ 0.001) along with significant interaction between test condition and gender (p ≤ 0.05) for tests of peak torque, rate of torque development, and power. Significant main effects were found for RVC/ NO-RVC condition (p ≤ 0.05) without significant interaction between test condition and gender for any test of muscle activation. The RVC condition produced 7.8 to 14.1% higher performance for all variables for men, and 5.5 to 12.7% higher values for women for peak torque and rate of torque development. This performance augmentation appears to be the result of 9.7 to 12.0 % higher prime mover activation for men and 11.5 to 15.3 % higher for women, in the RVC condition. Athletes and exercisers should consider using RVC's to augment upper body force and muscle activation during training.
