What this Trial Is About
This research aims to learn how Haskap berries affect recovery from intense resistance training in adults who regularly perform barbell squats. The study focuses on whether Haskap juice can speed up recovery from oxidative stress, inflammation, and performance loss caused by intense lower body workouts. Researchers will compare Haskap juice to a placebo matched in color, flavor, and carbohydrates, and may also analyze stored blood samples for further insights beyond the main questions. Participants will be randomly assigned to drink either a Haskap berry smoothie or a placebo smoothie twice daily for 11 days while following a low polyphenolic diet. They will complete an intense workout of barbell back squats and leg extensions. Blood samples will be collected before supplementation, before, immediately after, and several times up to 72 hours post-workout to track recovery. Performance tests including vertical jumps, quadriceps strength, and squat speed will be measured at 24, 48, and 72 hours after exercise. During the 11-day study, participants will have multiple blood draws and performance assessments to evaluate markers of inflammation, oxidative stress, and muscle damage. Questionnaires on soreness, diet, and sleep will also be completed. Researchers will monitor changes in force production, barbell velocity, vertical jump height, and various blood markers. This detailed monitoring will help understand how Haskap berries may influence recovery and performance after intense resistance exercise.
