Efficacy of Carotenoids on Blood Biomarkers Following A Collision Sport Athletes
Abstract
This is a supplement study being conducted to find out if collision sport athletes who are exposed to repetitive head impacts while supplementing with carotenoids will have decreased pro-inflammatory blood biomarkers, increases in macular pigment optical density, improved contrast sensitivity, greater retinal nerve fiber thickness, and better overall visual quality of life scores compared to collision athletes taking a placebo.
Conditions: Head Injury, Carotenoids.
Primary outcome: Blood and saliva biomarkers via venous blood draw and spitting into sterile cup.; Visual Performance: Speed of visual processing; Visual Performance: Contrast Sensitivity; Skin carotenoid concentration; Retinal Nerve Fiber Layer Thickness; Macular Pigment Optical Density; Visual Quality of Life Scores; Visual Quality of Life Scores.
Enrollment: 31 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 31 participants or records.
