Key result
Six months of supervised exercise training increased VO2 max by 13% (p < .0001) but did not significantly change cardiac sympathetic nervous system function measured by PET imaging.
Why the study?
Does 6 months of supervised exercise training change cardiac sympathetic nervous system function measured by PET imaging in healthy sedentary volunteers?
Population
Healthy sedentary male and female volunteers (young and old)
Comparison
6 months of supervised exercise training vs Baseline (before training)
Design
Cohort
Follow-up
6 months

Exercise boosts fitness without altering cardiac SNS by PET in healthy adults; leaves open effects in disease or with refined imaging.
Does 6 months of supervised exercise training change cardiac sympathetic nervous system function measured by PET imaging in healthy sedentary volunteers?
Six months of supervised exercise training improves fitness but does not significantly alter cardiac sympathetic nervous system function as measured by current PET imaging techniques in healthy volunteers.
Bernacki et al. (2016) studied Healthy sedentary volunteers. Supervised exercise training vs. Baseline (pre-training) was evaluated on Cardiac sympathetic nervous system function (PSnt, β'max) and myocardial blood flow. Six months of supervised exercise training increased VO2 max by 13% (p < .0001) but did not significantly change cardiac sympathetic nervous system function measured by PET imaging.
