High-intensity eccentric exercise could induce muscle damage and decrease exercise performance. This study investigated the beneficial effects of deep-ocean minerals liquid concentrate on eccentric-exercise induced muscle-damage recovery. Professional competitive swimmers (N = 10) were randomly assigned to placebo and deep-ocean minerals liquid concentrate groups. Ss performed upper extremity exercise (6 repetitions × 6 rounds at 85% 1 RM) to induce muscle damage in the biceps brachii. After exercise, Ss were randomly treated with either deep-ocean minerals liquid concentrate or placebo. Creatine kinase, myoglobin, muscle oxygenation, and oxygen consumption (measured by near-infrared spectroscopy) and biceps brachii power were measured at 4-hours, 24-hours, and 48-hours of post-exercise recovery.

Levels of myoglobin were not significantly different between groups. Biceps brachii power was significantly higher in the deep-ocean minerals liquid concentrate group than in the placebo group at 4-hours during post-exercise recovery. Muscle blood flow was significantly higher in the deep-ocean minerals liquid concentrate group compared to the placebo group. Muscle oxygen consumption was significantly higher in the placebo group than in deep-ocean minerals liquid concentrate group at 4-hours during post-exercise recovery.

Implication. Deep-ocean minerals liquid concentrate showed beneficial effects on muscle recovery after eccentric exercise.
