A new study, published in Nutrients, of 38 participants (19 men, 19 women) has found that drinking caffeinated coffee improves speed of cycling.

The study, which investigated the effect of coffee ingestion in a 5km cycling trial, found that it had a positive effect on the time trial performance of both sexes. The study's findings suggest that both men and women respond similarly to coffee and that coffee ingestion may be a practical source of caffeine prior to exercise to improve performance.

Participants restricted coffee consumption for 12 hours before drinking either: coffee providing 3mg.kg-1 of caffeine, a placebo in water or nothing as a control. In a 5km cycling time trial, following coffee ingestion, the performance of both men and women improved by approximately nine seconds and six seconds compared with placebo and control, respectively. No differences in performance were observed between the placebo and control.

The study contributes to the growing body of research that highlights the ergogenic benefit of coffee ingestion. To date, much of the research on this topic has focused only on anhydrous caffeine and on men.

About ISIC

The Institute for Scientific Information on Coffee (ISIC) is a not-for-profit organization, established in 1990 and devoted to the study and disclosure of science related to "coffee and health." Since 2003 ISIC also supports a pan-European education programme, working in partnership with national coffee associations in nine countries to convey current scientific knowledge on "coffee and health" to health care professionals.

ISIC's activities are focused on:

the study of scientific matters related to "coffee and health"

the collection and evaluation of studies and scientific information about "coffee and health"

the support of independent scientific research on "coffee and health"

active dissemination of balanced "coffee and health" scientific research and knowledge to a broad range of stakeholders.

ISIC respects scientific research ethics in all its activities. ISIC's communications are based on sound science and rely on scientific studies derived from peer-reviewed scientific journals and other publications.

ISIC members are six of the major European coffee companies: illycaffè, Jacobs Douwe Egberts,Lavazza, Nestlé, Paulig, and Tchibo.
