Dr. Robert Chapman and Dr. Timothy Mickleborough from the Department of Kinesiology are published in the December 2009 issue of The Physician and Sportsmedicine. The clinical focus of this issue is The Injured Athlete. Their article, titled "The Effects of Caffeine on Ventilation and Pulmonary Function During Exercise: An Often-Overlooked Response."
Abstract: The effects of caffeine on exercise performance have been well documented, with most reviews focusing on the metabolic, hormonal, and/or central nervous system effects. However, caffeine’s effects on ventilation and pulmonary function are often overlooked. Studies have shown that caffeine is a strong ventilatory stimulant, increasing the sensitivity of the peripheral chemoreceptors in untrained subjects and increasing exercise ventilation at all workloads in highly trained endurance athletes. The consequences of increased exercise ventilation could hold either positive or negative effects for exercise performance. Anti-inflammatory and bronchoprotective effects of caffeine are great enough to consider its efficacy as a possible prophylactic antiasthma treatment. Although an upper urinary concentration limit exists for caffeine with international sports doping control agencies, caffeine’s universal accessibility in the marketplace has resulted in its daily use being increasingly more socially acceptable as an ergogenic substance for sport and exercise.

Pretty much everything you say about caffeine is positive. But then you say "the consequences of increased exercise ventilation could hold either positive or negative effects for exercise performance." How important is this unknown? Do you this this negative could outweigh the positive? I was all geared for a cup of coffee before my workout today, but this made me question that. I guess I'll have to try it and see!

You said that caffeine is "Anti-inflammatory and bronchoprotective effects of caffeine are great enough to consider its efficacy as a possible prophylactic antiasthma treatment". Never thought that it could be use as such, is their any medical record that could prove that caffeine could actually be a anti asthma, if it is then it is great news for those people who has the said complication.
