Implication

Muscle group-specific responses merit caution in static exercise testing; leaves open clinical translation and mechanistic validation.

Structured PICO

Do static contractions of different muscle groups elicit different circulatory responses?

P
Population
11 male subjects (for forearm vs quadriceps comparison) and 10 subjects (for hand-grip vs foot plantar flexion comparison)
I
Intervention
Static muscle contractions at 15% and 25-30% maximal voluntary contraction (MVC) of forearm (hand-grips), quadriceps, and foot plantar flexor muscles
C
Comparator
Different muscle groups and different contraction intensities (15% vs 25-30% MVC)
O
Outcome
Changes in heart rate (HR) and intra-arterial blood pressure (BP)surrogate

The magnitude of the reflex cardiovascular response during static contractions varies by muscle group, likely due to differences in functional properties, muscle strength, and size.
