Competitive athletes are always looking for an extra edge. According to a study, they can find one in the common cranberry.
In a series of trials involving trained distance runners, the researchers found that ingesting a cranberry supplement for 28 consecutive days led to noticeable improvements in both performance and muscle fatigue following 1,500-meter time trials. Reoxygenation rates were faster, and running speeds improved by 1.5 percent.
The researchers recruited 14 high-level runners from Concordia's varsity track and field team and from two Montreal running clubs, who are performing at least five hours of endurance training a week.
The athletes ran two time trials over three separate visits, one a 1,500-meter, the other a 400-meter. The first visit was used as a baseline. At the second, they were given a single large dose of cranberry extract two hours before running. The athletes were then instructed to consume a small dose of cranberry extract daily for 28 days, after which they repeated the runs for a third time.
"We selected these distances to test the effects the cranberry extract had on different energy systems," says Francis Parenteau, a Ph.D. candidate.
Following data analysis, the researchers found that 28 days of cranberry extract consumption demonstrated a trend toward increased speed in the 1,500-meter time trial but not in the 400-meter. However, they did notice that lactate buildup was reduced following the 400-meter but not the 1,500-meter compared to baseline.
The data also indicated that the cranberry extract promoted better oxygen extraction by the muscle, improved lactate clearance, and slower muscle deoxygenation.
Cranberries are extraordinarily rich in polyphenols, a natural compound with antioxidant properties. These characteristics help protect the body from the harmful effects of free radical molecules produced by strenuous exercise.

Beet juice/kvass and natto work better.
You are right to be skeptical, but consider if it’s a commodity and also if it’s cheap to prove out for yourself, and then doing it to validate it.
Interesting beverage and food choices there, sir.
Good ones!
Too much and it will boost you right into the restroom.
YMMV

Enjoy your cranberry juice,
but Men, be careful not to let any juice drip when you’re wearing your white Bergdorf Goodman; Giorgio Cashmere dress shirt: priced at $3990.
Or, when slumming about in your Dunhill Luxury Cotton dress shirt, minimally priced at $725.00
Perfect solution: literally!
Plus it does wonders for my aging urinary track (65+).
Were I wearing such rags it would be high time to dispose of them along with my haberdasher lest someone confuse me with a Yale man like yourself.
They took extracts instead of a cranberry juice mix (usually about 15% cranberry juice). I wonder how much juice or whole cranberries one needs to consume to receive the benefit.
Lol!

“A total of 14 trained runners were tested at i) baseline, ii) 2 h following an acute CE dose (0.7 g/kg of body mass), and iii) 4 weeks after daily supplement consumption (0.3 g/kg of body mass).”
No idea how that translates into real juice, but the actual results were not impressive.
“CE consumption for 28 d demonstrated a trend toward improving running times for the 1500-m TT (P = 0.10; η2 = 0.15), but not for the 400-m TT (P = 0.39; η2 = 0.07). Although NOT STATISTICALLY SIGNIFICANT, the faster running time during the 1500m TT translated to a 1.5% mean increase in running speeds. Baseline lactate levels were the same at all time points (P = 0.27; η2 = 0.11). CE significantly buffered the lactate peak at 1 min post-run for the 400-m TT (P = 0.01; η2 = 0.27), but not for the 1500-m TT (P = 0.33; η2 = 0.08) (Figure 2).”

But - if you eat too many, you will get “bogged” down😎
Sorry - couldn’t help it - I love Craisins
Haha! I always wear a tomato-colored shirt while eating spaghetti or making sauce!
