A fitness instructor wants to investigate the effect of different aerobic training intensities on resting heart rate. Which data collection method would yield the most credible results?

Having participants self-report their resting heart rates each morning.
Using a standardised laboratory protocol with calibrated heart rate monitors.

B is correct: Using a standardised laboratory protocol with calibrated equipment provides the most credible results because it controls for variables and ensures measurements are taken under consistent conditions with accurate, scientifically validated equipment.

Other Options:

A is incorrect: Lacks credibility due to potential inconsistencies in self-reporting methods and participant error.
C is incorrect: Introduces variability from different staff members’ measuring techniques, reducing reliability.
D is incorrect: Problematic because measurements taken immediately upon arrival can be influenced by recent activity (walking, driving, etc.), not truly reflecting resting heart rate.
