Answer
A trained endurance athlete typically exhibits a lower resting heart rate when compared to an untrained individual. This is primarily because regular endurance training enhances cardiovascular efficiency. The heart pumps more blood per beat (increased stroke volume), requiring fewer beats per minute to maintain adequate blood flow.
Step 2
B) higher resting heart rate.

Answer
Endurance athletes usually develop more slow-twitch muscle fibers, which are better for prolonged activities. Thus, this option does not apply.
Step 4
D) decreased fast-twitch fibre concentration.

Answer
This answer is more appropriate as endurance training often leads to a relative decrease in fast-twitch fibers, which are more prevalent in strength and power athletes.
