The effect of the amount of eccentric exercise on ventilatory response at the onset of exercise.

We examined the effect of the amount of eccentric exercise (ECC) on ventilatory response at the onset of exercise. The first 10 s of ventilatory response to exercise while using the leg that had performed a relatively greater number of ECC repetitions was greater than that of the leg that had done relatively fewer repetitions, suggesting that ventilatory response at the onset of exercise varies with the degree of change in muscle condition after ECC.
