Final answer:
A trained individual typically has higher oxygen consumption, lower pulse rate, and less rise in blood pressure, but contrary to the statement, they have a larger stroke volume resulting from an efficient heart.
Step-by-step explanation:
The statement that a trained individual has higher oxygen consumption, lower pulse rate, smaller stroke volume, and a less rise in blood pressure is partly true and partly false. A trained individual does typically have higher oxygen consumption and a lower pulse rate.
However, trained individuals usually have a larger, not smaller, stroke volume due to a more efficient and stronger heart muscle developed through exercise. As a result, there is typically less rise in blood pressure during exercise compared to untrained individuals. The effect of exercise on the heart is such that a well-conditioned athlete is expected to have an increased stroke volume along with increased cardiac output during maximal physical activity, without excessive increases in blood pressure.
