Effect of Black Maca Supplementation on Inflammatory Markers and Physical Fitness in Male Elite Athletes.
Lee, Park, Kim, et al. Nutrients, 2023.
Study design: Clinical study in 44 elite male athletes (shooting, racket sports, and fin swimming). Capsules containing 2,500 mg of 100 percent concentrated black maca extract, one capsule twice a day for 8 weeks.
- Changes were seen in the ATP-PC energy system and the aerobic energy system, especially in fin swimmers.
- The authors linked this to increased antioxidant activity and factors regulating mitochondrial biogenesis.
- The authors called these findings early evidence; the abstract does not mention a placebo comparison group.
What it means for your product: The only study here that specifically used black maca. Relevant for product positioning in sports communities, with the caveat that the evidence is still preliminary.
