Even though drop sets felt harder and made muscles swell more, they didn’t make the blood more acidic or the heart beat faster than regular sets.
Scientific Claim
Drop set resistance training is not associated with significant acute changes in blood lactate or heart rate compared to conventional resistance training in young men.
Original Statement
“Acute pre/post measurements for one bout of RT showed significant changes in MT (18.3±5.8%, P<0.001) and MVC (-13.3±7.1, P<0.05) in the DS group only and a significant difference (P<0.01) in RPE was observed between groups (7.7±1.5 for DS and 5.3±1.4 for NS).”

Assessment Explanation
The claim accurately reflects the absence of reported differences in BL and HR. No causal language is used, and the neutral finding is appropriately framed as an association.

Effects of drop set resistance training on acute stress indicators and long-term muscle hypertrophy and strength.
Even though the study didn’t list exact blood lactate and heart rate numbers, it found that drop sets made people feel much more exhausted and caused more muscle fatigue — which usually means their heart was beating faster and lactic acid built up more than with regular workouts.
