Study Finds Supplementation With DHA May Improve Performance in Cyclists
A recent study suggests that supplementation with highly concentrated DHA may provide cardiorespiratory benefits and improve power output in amateur cyclists.
Thirty-eight amateur competitive male cyclists participated in the study. They were given 975 mg of DHA and 120 mg of EPA or a placebo daily for 30 days. They performed a maximal cycling test at baseline and at the end of the study period to evaluate performance. Ventilatory threshold, which is the intensity of exercise above which your breathing becomes labored and you feel you just can’t draw in as much air as your body wants, was also measured.
Participants in the supplement group saw improvements in power output and ventilatory threshold compared to the placebo group. This reflects improvements in aerobic capacity. Heart rate recovery rate post exercise also improved in the supplement group compared to the placebo group.
The study was conducted by researchers from San Antonio Catholic University of Murcia. It was published online ahead of print on October 21, 2020 in the Journal of the International Society of Sports Nutrition.
