The addition of seawater did not significantly enhance these effects beyond resistance training alone.
Participants were allocated to four groups: resistance training plus seawater (RT+SW), resistance training plus placebo (RT+PLA), control plus seawater (CON+SW), and control plus placebo (CON+PLA). The resistance training intervention involved twice-weekly, submaximal, whole-body exercises. The study found significant improvements in almost all measured variables (strength, bone health, body composition, quality of life) within both resistance training groups compared to baseline. When compared to control groups, significant differences were observed only in isokinetic strength, body fat percentage, and the bodily pain subscale of the SF-36. RT+PLA), though the RT+SW group generally showed greater effect sizes. The study concludes that the resistance training program itself was the primary driver of adaptations, with seawater supplementation not providing a statistically significant additional benefit for most outcomes. A limitation noted is the lack of measurement of acute effects of seawater on resistance training performance.
