Altitude, Hydration, and Athletic Performance

Why was this study done? Changes in altitude effect absorption and distribution of water and electrolytes in the body. This study was designed to understand how differing rehydration formulas (containing different concentrations of electrolytes) are effected by altitude. What did the study find? This study found that induction and maintenance of hypervolemia at altitude relies…

Do Sports Drinks Cause Kidney Stones?

Why was this study done? To investigate the effects of two sports drinks (“G” or “P”) and whether they produce or prevent the formation of kidney stones. What did the study find? “P” increased citrate excretion (by 170 mg/day) and increased urine pH (by 0.31), whereas “G” did not change citrate excretion or pH. These…
