Which statement is most accurate concerning cardiovascular adaptations in a resistance-trained athlete?
A) increases in cardiac output are generally seen after 8-10 weeks of training
B) walls of the left ventricle increase in size at the expense of internal diameter
C) walls of the left ventricle increase in size with no change in internal diameter
D) resting blood pressure become elevated

Question

Quizplus · Accepted Answer

Resistance training can lead to left ventricular hypertrophy, which means that the walls of the left ventricle increase in size. However, this is often accompanied by an increase in internal diameter, which allows for an increase in cardiac output. Therefore, option A and B are incorrect. Resting blood pressure can increase in individuals with high levels of muscularity, but it is not a consistent finding in all resistance-trained athletes. Therefore, option D is incorrect. Option C is the most accurate statement as it describes the most common cardiovascular adaptation seen in resistance-trained athletes, i.e., an increase in the thickness of the left ventricular walls with no change in internal diameter.
