Effects of Polymethoxyflavone Rich Kaempferia parviflora Extract on Physical Fitness

The study investigated black ginger (Kaempferia parviflora) extract rich in polymethoxyflavones (PMFs) for its effects on physical fitness and fatigue in healthy adults using a randomized, double-blind, placebo controlled crossover design. Participants consumed 30 mg/day of the extract for four weeks, after which multiple physical performance parameters were assessed. The intake of the extract significantly improved grip strength, lower body strength (chair stand test), balance (tandem walking), and endurance (cycle ergometer performance) compared with placebo. These effects are associated with the ability of PMFs to enhance muscle metabolism, potentially through activation of AMP activated protein kinase (AMPK), supporting energy utilization and muscular function. In addition, the extract showed reductions in subjective fatigue scores, particularly in individuals without regular exercise habits, indicating improved recovery and reduced perceived exertion. Overall, polymethoxyflavone rich black ginger extract enhances physical performance, supports muscular function, and reduces fatigue, for improving fitness and preventing decline in physical capacity.
