The American College of Sports Medicine and AHA recommendstretching exercises before aerobic exercise to increase therange of motion in joints and thus protect injury in muscles and
joints.
a previous studystretch stimulus to rats lung vessels increasesnitric oxide (NO) production from vascular endothelial cells.
impaired NO-dependent vasodilation is an independentpredictive factor of cardiac events in IHD patients.

THE AIM
to determine the effects of a single sesion of
stretching exercises on vascular endothelial function
and peripheral circulation in patients with acute
myocardial infarction (AMI).

DISCUSSION
8/11/2019 Slide Rehab
13/18
one round of stretching exercises increased NO production fromvascular endothelial cells in AMI patients
mainly reflects NO-dependent vasodilation
Highly reliable and reproducible as a parameter for vascular endothelialfunction and shows close positive correlation with assessment
Increased significantly as an acute effect

Other study
Awolesi etal
showed upregulation of eNOS mRNA expression in bovine vascularendothelial cells subjected to cyclic stretch stimuli for 15 minutes and
increased eNOS translation with 24-hour cyclic stretch stimuli
Lansmanet al
a single stretch stimulus to vascular endothelial cells immediatelyincreased the opening frequency of Ca channels in the cell membrane

DISCUSSION
the stretching exercises increase peripheral blood flow througharterioles and capillaries rather than blood flow through the great
vessels in the upper and lower extremities.
the Foot-tcPO and Foot-tcPO2/Chest-tcPO2 ratio (indicates theperipheral blood circulation via arterioles and capillaries), were
significantly higher after the exercises than before
CAVI and ABI (to evaluate arterial stiffness great arteries )did notchange significantly before and after the exercises;

Cardiac parasympatheticnervous activity was
significanly enhancedafter the stretching
exercises in AMIpatients, becauseelevated HF was
observed as an acuteeffect

CONCLUSIONS
The stretching exercises performed in the present studyenhanced vascular endothelial function, resulting in
improved peripheral circulation in patients with AMI. the stretching exercises did not induce excessive
hemodynamic instability
