Independent and Combined Effects of Short-term Sulforaphane Supplementation and Exercise on Immunometabolism in Healthy Adults (EXSFN)

2026年7月15日 更新者:Hashim Islam、University of British Columbia

Independent and Combined Effects of Short-term Sulforaphane Supplementation and Exercise on Immunometabolism in Healthy Adults: A Randomized Crossover Study

The study consist of 3 interventional periods which will be completed by each consenting participant in a randomized, crossover fashion. The interventional periods will be separated by a minimum 1 week washout period. One of the interventions consists of 4 days of daily supplementation with the commercially available broccoli sprout extract capsules (BrocElite). Another intervention will consist of 4 days of daily supervised treadmill running. The exercise protocol consists of 4 minutes of high-intensity running running followed by a 3 minute recovery period, repeated for a total of 4 repetitions. The last intervention combines the above two and consists of 4 days of daily supplementation and daily supervised exercise training. Before and after each intervention, basic anthropometrics (weight, heart rate, and blood pressure) will be recorded, and a venous blood sample will be collected. Blood samples will be analyzed for metabolic and inflammatory markers. Participants will be asked to refrain from structured exercise, alcohol consumption, and broccoli consumption during each of the experimental periods. Before any testing, willing participants will provide informed consent, and fill out a few demographic, and lifestyle questionnaires. The study will be conducted at the University of British Columbia in Kelowna, BC, Canada.

武器和干预

参与者组/臂
干预/治疗
实验性的:Sulforaphane Supplementation Only
In this intervention, participants will consume commercially available broccoli sprout extract capsules daily for 4 days (20 mg/day) . Basic anthropometrics (weight, heart rate, blood pressure) and a venous blood sample (30 mL) will be collected before and after this interventional period.
Broc Elite Plus stabilized sulforaphane capsules from Mara Labs
有源比较器:Exercise Only
In this intervention, participants will complete supervised exercise sessions daily for 4 days. The exercise intervention consists of interval running on a treadmill which contains 4 cycles of: 4 minutes of intense running (85-95% HRmax) followed by 3 minutes at a slow, easy pace. Basic anthropometrics (weight, heart rate, blood pressure) and a venous blood sample (30 mL) will be collected before and after this interventional period.
4 cycles of: 4 minutes of intense treadmill running (85-95% HR max) followed by 3 minutes of slow, easy running.
