In a study investigating the impact of acute sleep deprivation on elite rowers' pacing strategies and perceived exertion during a simulated 2000 m time trial, researchers combined multiple methodology streams: self-reported post-trial exertion surveys (using the Borg CR10 scale), continuous chest-strap heart rate telemetry (physiological data), and high-frequency optical motion-tracking of the oar angle and stroke rate (biomechanical performance data).
Explain at least one strength of using this combination of research methods to investigate the rowers' pacing strategies and exertion, with specific reference to the validity of the study's conclusions.
