Forearm endurance training attenuates sympathetic nerve response to isometric handgrip in normal humans
Why the study?
Does 6 weeks of unilateral handgrip endurance training attenuate the sympathetic nerve response to isometric handgrip in normal subjects?
Population
8 normal subjects
Comparison

Implication
May attenuate sympathetic responses to isometric exercise in healthy subjects; hypothesis-generating and leaves open relevance to patients.
Structured PICO
Does 6 weeks of unilateral handgrip endurance training attenuate the sympathetic nerve response to isometric handgrip in normal subjects?
P
Population
8 normal subjects
I
Intervention
6 weeks of unilateral handgrip endurance training (right arm)
C
Comparator
Sham training (left arm)
O
Outcome
Muscle sympathetic nerve activity (SNA) response to isometric handgrip (IHG: 33% of maximal voluntary contraction maintained for 2 min)surrogate
Six weeks of unilateral handgrip endurance training significantly attenuates the sympathetic nerve response to isometric handgrip in normal subjects, likely by decreasing muscle chemoreflex stimulation.
