Gelatin may improve endurance by 240 percent, claims forgotten study
Luckily, while browsing through a dusty library, we stumbled upon a virtually forgotten pre-World War II study. Otherwise, we would never have known that in 1939 researchers seriously studied whether gelatin might be a sports supplement that improves endurance.
Gelatin
Study
The researchers used a product from the American Knox. It is still in American stores, by the way. They dissolved 30 grams of that powder in 240 milliliters of citrus fruit juice and gave the gelatin shakes to their subjects.
The researchers experimented with 6 men and 4 women. All subjects were supplemented with gelatin for approximately 7 weeks.
The researchers used a product from Knox, which is still available in American stores. The researchers dissolved 30 grams of this powder in 240 milliliters of citrus fruit juice and gave the gelatin shakes to their subjects.
The men consumed 60 grams of gelatin per day. Three women were given 45 grams of gelatin per day, one 62.5 grams of gelatin per day. When the supplementation was over, the researchers still gave the subjects fruit juice, but without gelatin.
During the experiment, the subjects had to cycle on a velometer several times until they were tired. The researchers then calculated how many Watts the study participants could generate.
There were no exercise protocols in the 1930s. The subjects probably made a submaximal effort.
Results
The researchers did see an increase in endurance in the men during the supplementation phase. The amount of Watts generated increased by 37 to 240 percent.
The researchers did not understand why women did not respond to gelatin supplementation.
A scientifically obsolete curiosity?
Soon we will continue.
