The major focus of research in our laboratory is the effect of exercise on the respiratory muscles, including both fatigue and training of respiratory muscles.

To this end, we have evaluated various durations and intensities of exercise on respiratory fatigue and alterations in pulmonary function. We have also examined the effects of different exercise metabolites, including lactate, ammonia, and free radicals, on the diaphragm to determine whether they might be part of the cause of exercise-induce respiratory muscle fatigue.

Future studies proposed will involve using non-respiratory activities such as sit-ups to fatigue and train the respiratory muscles, as a possible rehabilitation intervention for certain pulmonary diseases.

We have also performed studies on performance in activities including cycling, running/walking and rowing. These activities, particularly in elite or near-elite athletes, provide insight into the maximal capabilities of the human species, allowing us to determine some of the limitations to exercise, as well as the response to specific training.
