Which of the following statements concerning adaptations to endurance training is incorrect?

The statement regarding maximal heart rate being increased following endurance training is incorrect because endurance training does not lead to an increase in maximal heart rate. Instead, maximal heart rate is primarily determined by age and does not generally change as a result of training. With endurance training, the body adapts in various ways, but a rise in maximal heart rate is not one of them.

In contrast, stroke volume, which is the amount of blood ejected from the heart with each beat, is typically increased due to adaptations such as improved contractility and increased chamber size.

Furthermore, heart rate at submaximal intensities generally decreases with endurance training, reflecting enhanced cardiovascular efficiency and a better ability of the heart to pump blood with fewer beats.

Additionally, endurance training improves the strength of ventricular contractions, allowing the heart to pump more efficiently and effectively during both exercise and rest. These adaptations contribute to an overall improved ability to perform endurance activities.
