Assessing the Effectiveness of Selected Biomarkers in the Acute and Cumulative Physiological Stress Response in Professional Rugby Union through Non-invasive Assessment.

abstract：:It has been asserted that the consumption of oxygenated water can support physical working capacity. As this has not been accurately investigated yet we analyzed effects of a two-week period of daily O2-water ingestion on spiroergometric parameters and lactate metabolism in healthy adults. Twenty men (24 +/- 2.5 years...
