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.

INTRODUCTION


3/18

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).

METHODS

32 patients whoreceived phase Icardiacrehabilitation afteracute myocardialinfarction.

DISCUSSION


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

RH-PAT INDEX

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


15/18

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;


16/18

Cardiac parasympatheticnervous activity was

significanly enhancedafter the stretching

exercises in AMIpatients, becauseelevated HF was

observed as an acuteeffect

stimulate NO releasefrom vascular endothelial

cells via acetylcholinerelease from its terminal

ends.

Vasodilation inthe extremities


17/18

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
