Abstract
Purpose: To examine the effects of multiple dexamethasone iontophoresis treatments on Delayed Onset Muscle Soreness (DOMS) by evaluating muscle damage and inflammatory blood markers of creatine kinase (CK) and interleukin-6 (IL-6); pain using a visual analog scale (VAS) and an algometer strain gauge (ASG). Methods: Twenty untrained subjects (age, 23.55 ± 3.03yr; height, 175.24 ± 8.76cm; weight, 90.27 ± 17.78kg), assigned to either a dexamethasone or saline group, performed eccentric bicep brachii curls on the non-dominant arm. Baseline measurements included VAS, ASG, and a blood draw to evaluate CK and IL-6 levels. Following exercise, 10 subjects received an iontophoresis treatment of dexamethasone (Dex. group) while ten control subjects received a saline solution (Placebo group). Subjects were given the same iontophoresis treatment immediately, 24, and 48h after eccentric exercise. Dependant variables were evaluated again at 24, 48, and 72h post-exercise. Results: No significant differences were found between treatments and CK (Placebo = 379.7 ± 189.7 UI·L·1, Dex. = 561.8 ± 189.7 UI·L·1;p=0.506), IL-6 (Placebo 0.1 ± 0.0 μ/mL, Dex.= 0.2 ± 0.0 μ/mL; p=0.85), VAS (Placebo = 2.3 ± 0.3 cm, Dex. = 1. 7 ± 0.3 cm; p=0.198), and ASG (Placebo = 1.9 ± 0.2 kg, Dex.= 1.8 ± 0.2 kg; p=0.806). Conclusion: Dexamethasone iontophoresis does not appear to be effective in alleviating acute muscle injury or pain.
