Deep Ocean Minerals

Hydrothermal systems in the deep ocean was propose to be among; the most credible settings for the biological origins of life. Indeed, such alkaline systems have been suggest as the source of the evolution of primordial metabolism. The marine environment possesses a rich pool of bio-active ingredients with numerous purported health benefits. Moreover, novel marine-based bioactive compounds might also augment human performance, especially in those who engage in physical activity.

Administration of deep ocean minerals (DOM) has previously demonstrate positive effects; on exercise performance in animal and human models. For example, Hou et al. reported that DOM extracted from 662 m; below the ocean surface facilitated substantially quicker recovery from a prolonged bout of exercise at 30 °C; which induced 3% reduction in body mass of healthy males.

More specifically, maximal oxygen uptake (V·O2MAX) increased by ~2% after 4 h compared to baseline with DOM; whilst it was reduce ~11% with placebo. After 24 h, V·O2MAX increased by ~6% compared to baseline with DOM; whilst it was ~13% lower with placebo. The authors opined that specific elements in DOM, such as boron, magnesium and rubidium; were likely to have contributed to the observed ergogenic effects.

Deep mineral water

Interestingly, using a similar protocol, Stasiule et al. reported comparable differences in aerobic capacity of healthy females 4 h after supplementation with (deep) mineral water (DMW); extracted from a well at a depth of 689 m or placebo (purified tap water). Similarly, these authors also postulated that the minerals and trace elements that constituted DMW may have worked collaboratively to recover normal human performance.

Oral ingestion of DOM has previously demonstrated positive effects on exercise performance in humans; although such benefits have been observed during exercise after recovery from an initial bout of prolonged dehydrating exercise in the heat (i.e., 30 °C). Therefore, the aim of this study was to examine whether DOM facilitated ergogenic benefits; during exercise after recovery from an initial bout of prolonged exercise in more thermoneutral conditions (i.e., 20 °C). In support of our hypothesis, DOM increased high-intensity intermittent running capacity in recreationally active soccer players at the group level by 56%.

Thermoneutral environmental conditions

However, assuming a conservative daily variation of ~10% for a high-intensity exercise capacity test, and after accounting for any potential order effects between Trials 1 and 2 of ~20%, we suggest the minimum likely ergogenic effects after DOM at the group level to be ~25%. In summary, oral ingestion of DOM seems likely to promote ergogenic benefits for recreationally active soccer players after recovery from prolonged exercise in thermoneutral environmental conditions; however, given the somewhat variable results, an individual approach to supplementation is warranted.

In the present study, body mass was greater at baseline compared to after 60 min running at 75% V·O2PEAKafter 2 h recovery and at the end of the high-intensity intermittent exercise capacity test. The majority of this reduction in body mass over time is most likely indicative of sweat losses.
