Key result
Mental arithmetic significantly increased heart rate from 72.35 to 80.38 beats/min, systolic blood pressure, and cardiac output, demonstrating time-dependent autonomic nervous system and cardiovascular responses.
Why the study?
Does mental arithmetic task alter cardiovascular and autonomic responses in healthy male subjects?
Population
34 healthy male subjects aged between 19 and 27 years old with no cardiovascular related disease.
Comparison
Mental arithmetic task. vs 5-minute baseline rest period.

Does mental arithmetic task alter cardiovascular and autonomic responses in healthy male subjects?
Absolute Event Rate: 80.38% vs 72.35%
p-value: p=<0.01
Mental stress induces time-dependent cardiovascular responses characterized by initial parasympathetic withdrawal followed by sympathetic activation, regulated by prefrontal and temporal cortices.
Wang et al. (2016) conducted an observational in Healthy (n=34). Mental arithmetic task vs. Baseline rest was evaluated on Heart rate (beats/min) (p=<0.01). Mental arithmetic significantly increased heart rate from 72.35 to 80.38 beats/min, systolic blood pressure, and cardiac output, demonstrating time-dependent autonomic nervous system and cardiovascular responses.
