Abstract
An Institutional Review Board (IRB)-approved study was conducted to investigate the effects of the Tsunami Bar® (TB), a flexible barbell, on ground reaction force (GRF) production and muscle activity in the quadricep, hamstring, and gluteal muscle groups during phases of the squat exercise and compare the effects to the effects to using a rigid barbell (RB). A two-by-two repeated measures Analysis of Variance (ANOVA) test was used to compare the results. Descriptive statistics showed significantly higher GRFs for the TB during the unweighting phase, significant differences in GRFs between speeds for each phase, significantly higher forces on average with the RB during the breaking and propulsive phases at the 90 beats-per-minute (bpm) speed, and significantly higher muscle activity with the RB at the 60-bpm speed. A linkage to the beneficial effects of the TB seen in literature was seen with familiarity with the TB.
