On the dribbling track, the soccer players could have exercised at an intensity considerably higher than that shown in this experiment. In fact, in line with observations from running training (without a ball), the players had to be told to reduce their intensity in the first interval, so as not to exceed the planned intensity of 90–95% of fcmax. Higher exercise intensities lead to increased lactate levels and a lower aerobic training response, and often result in fatigue and failure to
