Low-dose of acute caffeine consumption in coffee form do not improve isokinetic strength performance.

This article focuses on the acute effects of low-dose caffeine consumption in coffee form on isokinetic knee strength performance in physically active males. In a double-blind, randomized, crossover study involving twelve male university students, caffeine doses of 1.5 mg·kg⁻¹ and 3 mg·kg⁻¹ were compared to a placebo (decaffeinated coffee) for their impact on single-leg isokinetic knee flexion and extension strength at angular velocities of 60°/s and 180°/s. The results showed no statistically significant differences in peak moment, total work, or rate of perceived exertion between caffeine and placebo conditions, indicating that low-dose caffeine intake did not enhance knee strength or alter perceived exertion. The study concludes that acute low-dose caffeine supplementation in coffee form is insufficient to improve isokinetic knee strength in this population, suggesting further research is needed with varied doses, exercise modalities, and participant characteristics.
