Potential Ergogenic Effects of Saffron

Area of Science:

• Sports Science
• Nutritional Science
• Pharmacology

Background:

• Crocus sativus (saffron) contains carotenoids with potential health benefits.
• Muscular strength, pulmonary function, and reaction time are key determinants of athletic performance.

Purpose of the Study:

• To investigate the ergogenic effect of saffron supplementation on physical performance in healthy, non-active male university students.
• To assess saffron's impact on muscular strength and reaction times.

Main Methods:

• Twenty-eight participants were randomized into saffron (300 mg/day for 10 days) and placebo groups.
• Measurements included anthropometrics, visual/audio reaction times, and isometric/isotonic forces (leg press) before and after supplementation.

Main Results:

• Saffron supplementation significantly increased isometric force (10.1%) and isotonic force (6.1%).
• Faster visual and audio reaction times were observed in the saffron group.
• Statistical significance was reached for all measured improvements (p < .0001 for forces, p < .05 for reaction times).

Conclusions:

• Ten days of saffron supplementation demonstrated ergogenic effects, enhancing muscular strength and reaction speed.
• Potential mechanisms include increased muscle mitochondrial biogenesis, positive effects on the motor cortex, improved muscle blood perfusion, and facilitated oxygen transport.
• Saffron shows promise as a supplement for improving physical performance.
