Why the study?
Does higher intensity resistance exercise (70% 1-RM) increase heart rate and blood lactate response compared to lower intensity (50% 1-RM) in male subjects?

Does higher intensity resistance exercise (70% 1-RM) increase heart rate and blood lactate response compared to lower intensity (50% 1-RM) in male subjects?
Higher intensity resistance exercise (70% vs 50% 1-RM) produces significantly greater increases in heart rate and blood lactate concentrations, which escalate with successive sets.
