The effect of exercise hyperpnea on gross efficiency and anaerobic capacity estimates during a 3-min cycle time trial Open
This study demonstrates that GE declines during a 3-min supramaximal cycle TT, which is possibly related to the hyperpneic response during supramaximal exercise. The finding from this study also provides novel insight into how the increase…
