Haskap berries for faster recovery after intense resistance workouts
Official title: Impact of Haskap Berries on Recovery From High Intensity Resistance Training
Run by Montana State University · NCT07344727 · Data updated 2026-11-12
This tests whether drinking Haskap berry juice helps resistance-trained adults recover faster from intense lower-body workouts by lowering inflammation and oxidative stress.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are resistance-trained adults who have at least 2 years of barbell squat experience and currently squat at least once per week, and who can follow the diet and visit schedule.
✕Probably not a fit
Those who are pregnant or lactating, have diabetes or thyroid disorders, smoke, have recent lower-extremity injuries, have BMI under 18 or over 40, have allergies to study ingredients, take interfering medications or supplements, follow specialty diets, or already consume certain berry products are excluded and unlikely to benefit from participation.

What this trial studies
This is a randomized, double-blind, placebo-controlled, parallel trial comparing Haskap berry smoothie to a matched placebo in resistance-trained adults. Participants follow a low-polyphenolic diet for 11 days, complete an intense lower-body workout (barbell back squats and leg extensions), and consume the assigned beverage. Blood is drawn before supplementation, before exercise, immediately after, and at 8, 24, 48, and 72 hours post-exercise to track inflammation and oxidative stress markers, and performance is measured with vertical jumps on force plates and standard strength tests. Stored samples may be used for secondary analyses of blood metabolites, and no genetic analyses or race/ethnicity-based analyses will be performed.
Why it matters
Potential benefit: If successful, Haskap supplementation could shorten recovery time and reduce post-workout inflammation and oxidative stress, helping trained athletes return to full performance sooner.
How similar studies have gone: Related research on other polyphenol-rich berries (for example tart cherry and pomegranate) has sometimes shown reduced post-exercise inflammation and soreness, but Haskap-specific clinical evidence is limited.
