SOS releases research study challenging the effectiveness of sugar in sports drinks.
Study results challenge the idea that sugar additives equal energy in sports drinks
March 10, 2014 (Los Angeles, CA)
SOS Rehydrate is the new healthy rehydration drink comprising the right balance of electrolytes for optimum hydration. The beverage is 100% free from artificial sweeteners, preservatives, flavors and colors.
SOS Rehydrate recently conducted an independent research study which found that SOS Rehydrate is capable of providing substantial rehydration and fluid retention, without the unnecessary excess sugar contained in the majority of leading sports drinks. This hydration capability, coupled with low sugar content, is what makes SOS Rehydrate the go-to drink of choice for many elite athletes.
This study, conducted by the Sports Performance Research Institute of AUT University, recruited 8 mid level distance runners who performed two single blind trials. During the trials, the participants consumed 500 ml of either the current sports drink market leader or SOS Rehydrate, followed by a 75 minute treadmill run while having their blood glucose, blood lactate, heart rate, blood pressure and feelings of thirst and fatigue recorded.
The runners’ results indicated that there were no statistically significant difference between the trials, thus challenging the notion that high levels of sugar are essential for aerobic performance and stamina. The market leading sports drink contains seven times more carbohydrates in the form of sugar (36 grams vs. 5 grams) than SOS Rehydrate, yet all participant performance measures were identical.
“The preliminary research results could not have been any more favorable to SOS Rehydrate’s mission to provide a healthy sports and lifestyle drink to the world,” said Dr. Lizaola, co-founder of SOS Rehydrate. “We have created a product that not only meets the World Health Organization’s standards, but also provides substantial rehydration without unnecessary excess sugar, that can potentially put our health at risk.”
Since the recent study indicates that high sugar content does not increase performance, SOS Rehydrate encourages consumers to question their sugar level intake as it can potentially lead to long term health problems such as chronic dehydration, obesity, diabetes and hypertension.
SOS Rehydrate Independent Research Study Findings Feb 2014
For many years Oral Rehydration Therapy (ORT) has been used to treat mild to moderate dehydration due to cholera and other gastrointestinal pathologies all over the world. It has saved more than 5 million lives, and it has proven its effectiveness through a myriad research studies. SOS Rehydrate applies the same principles used in the clinically proven ORT, to hydrate athletes and those with active lifestyles.
But how does it work? Water and electrolytes get absorbed all over the intestinal lumen through specialized energy-dependent pumps and co-transports. Within the small intestine there is a co-transport system that links one molecule of sodium to one of glucose; transferring sodium through the intestinal membrane into the blood stream. As a result of this sodium movement (osmotic gradient) water gets transported into the plasma. In essence by mixing the correct amount and ratio (1:1) of sodium and glucose the water absorption process gets enhanced by up to 3 times. Additionally this osmotic balance can aid in greater fluid retention, as renal reabsorption of water is favored in these conditions. However, as much peer reviewed clinical research has been conducted on the efficacy of a 1:1 sodium and glucose solutions osmolality, and resultant rapid fluid uptake, performance specific testing of this is a relatively new endeavor. To preliminary investigate the effectiveness of SOS Rehydrate verses the current Sports drink market leader, SOS Rehydrate commissioned the following study.
Effects of ingestion of SOS Rehydrate vs. Sports drink Market Leader on subsequent aerobic exercise:
This study, conducted by the Sports Performance Research Institute of AUT University comprised 8 mid level distance runners (6 males, 2 females) who performed two single blind trials in which they consumed 500 ml of either the current sports drink market leader (ML) or SOS, followed by a 75 minute treadmill run in a climate controlled room (~23 deg C, 60%rH), at a speed equivalent to 70% of their predetermined VO2 max. Prior to, Post, and every 20 minutes during these trials, measures of the runners’ blood glucose and blood lactate levels, as well as their heart rate, blood pressure, Rate of Perceived Exertion and feelings of thirst and thermal fatigue were collected and recorded. Additionally, to determine the runners’ hydration statuses prior to, during (if runners had to urinate during trial), and immediately post each 75-minute trial, measures of urine specific gravity and volume of urine produced were taken. Insensible and evaporative fluid loss, from sweating and breathing, were accounted for by pre and post body weights, and as the subjects were restricted from eating or drinking during the protocols, all weight loss was assumed to be due to fluid loss.
Following the completion of data collection, all subject data was averaged, and trial group means and standard deviations for each time point were generated. Upon statistical review, it was determined that for all recorded measures there were no statistically significant differences between either trial conditions means.
Below Figures 1-3 depict the mean trial values of Heart Rate, Blood Lactate, and Blood Glucose respectively.
This study was a positive step in demonstrating the effectiveness of SOS Rehydrate, and its 7 fold reduction in sugar content, in hydration and running performance when compared to the market leader. SOS Rehydrate is committed to furthering sports performance and hydration research, and as such will be initiating future studies to further investigate the effect of SOS Rehydrate on hydration status and performance, as well as post ingestion fluid retention rates.
