dex decreased by
6. 3 times than the period of pre-exercise (P<0. 01) ,the right decreased by
8. 1%(P<0. 05); the
left ascending time decreased by
21. 2%(P <C0. 01), but the right in-
creased a
bit. It shows that qigong exercise can increase blood volume of the brain and de-
crease cerebrvascular resistance.

tance decreases after the exercise. To sum up, qigong may harmonize the blood circulation re-
markably , playing a very important role
in preventing and cure of cardiovascular and cere-
brovascular diseases and lower limb disease. Qigong
is
a kind of exercise to harmonize the
mind
, breathing and bodily posture, a rehabilitative method for many chronic diseases. The
result has provided a preliminary experimental basis for preventing and curing the circulatory
system diseases.

The paper reports the effect of qigong on the heart function. The trainees involved
in
this experiment were 37 middle-aged intelligentsia ,25 males and 12 females between 35 to 45
years old. During the first three months, the subjects accepted the emitted qi remedy twice a
week besides their independent exercises for an hour, twice a day. In the next nine months,
the trainees practiced by themselves without the emitted qi remedy. A RM-6000 polygraphy
was used to record electrocardiogram (ECG) ,phonocardiogram (PCG)and carotid artery pulse
(CAR) simultaneously three months before and after the emitted qi remedy as well as a year
later respectively to determine the left heart systolic time intervals. After three months of the
emitted qi remedy the trainees
heart rate (HR) ,electromechenica systole (Q-S2)
, projection
period (PEP)
, left
ventricle contraction time (LVET ), systolic pressure (SP) and
diastolic
pressure (DP) were not statistically different from those of three months before. While after
one year of practice, the measurements were found to have a significant difference compared
with those of before the exercise in all the index mentioned above except HR ,isovolumic con-
traction time (IVCT ) and Q-S2. The following table indicates that qigong practice improves
the heart function.

The final conclusion has prevailed for long that respiration has a definite effect on car-
diovascular function. The Institute of Physio-Medical Engineering of the China Academy of
Medical Science has put forth the training model of respiration by making use of the cardio-
electric feedback control. Through such a specific breathing drill, it
is intended to enable the
internal pressure of the chest of one under training to take the shape of a step-leap of each in-
halation phase, and precisely at the time of the systole of the heart (a certain time after thq
cardioelectric R wave)
it positively increases the transmural pressure of the chest aortas, thusi
lowering the obstruction of the cardiac ejetion of the heart. The repeated chest internal pres-:
sure^ coming from the exhale phase occur exactly at the time of the beginning of the diastole
of tlje heart (a time after the cardioelectric T wave)
, positively reduce the transmural pressure:
of the chest aorta
, increase the systolic pressure of the arteries and enhance the perfusion
pressure of the blood supply of the coronary vessels. Just as the effect of the negative step-
leap jof the chest internal pressure in the course of inhale on the heart and arteries
is similar
to tHe effect of the counterpulsation of the pneumatophore (JABP)of the arteries on the air
discharge of the pneumatophore at the time of the systole of the heart, the positive step-leap
of the chest internal pressure on the coronary vessels is similar to the effect of JABP air-filled
ditalqtion. Therefore
, this self-controlled step-leap respiration plays
its own feedback
role.
Due to
its specific design, it has a favourable effect on the function of the coronary vessels
through effectively increasing the transmission of pressure from the chest pump to the heart
pump. Researching observations in contrast were conducted on two groups of persons under-

going experiments (30 cases of healthy youths and 14 cases of chronic heart problem)concern-
ing the function of their coronary vessels before and after the training. The data emanating
from a colour Doppler supersonic diagnostic instrument showed that the self-controlled step-
leap respiration training could distinctly slow down the rhythms of the heart of one under ex-
periment , mitigate the afterload of the heart
, increase the distolic pressure so as to increase
the pressure of the entrance to the coronary vessels , increase the discharge amount at each
pulsation and reduce the work function of the heart. It has a definite role to play in the im-
provement of the diastolic work of the
left ventricle , the enhancement of the adaptibility of
the left ventricle and the improvement of the working condition of the right ventricle. At the
same time, it can greatly mitigate such subjective symptoms as a sense of suppression in the
chest, chest pain and shortness of breath for those suffering from obstruction of heart func-
tions. Due to its features, such as its non-invasive nature, its non-medicinal nature and simple
method, it undoubtedly provides an entirely new method for the recovery and treatment of
the heart problems.

, Shanxi University,
Taiyuan 030006
Taijiquan is a kind of internal qigong and the meridian theory is one of the fundamental
theories of qigong. By using electroencephalographs (EEGs)and vibration transducers the au-
thor tested the electroencephalograms
, meridian waves and electrocardiograms (EECs)m thir-
ty Taijiquan exercisers and thirty-one non-Taijiquan exercisers. The following results clearly
demonstrated the Taijiquan group, the degree of coupling between the“heart-meridian”and
H/L value of Baihui(Du20)was noticeably higher than the control group(P<0. 005, P<0.
002). When the Taijiquan group entered a relaxed state, the frequency of the meridian waves
compared with the waves of the non-Taijiquan group reduced (P<0. 05).
This paper holds that Taijiquan promotes smooth flow of qi and blood to get rid of dis-
eases. In additionTtaijiquan may help people to reach utmost harmony or coupling of the vari-
ous systems of the body.

^Through a general survey we have monitored at random the people who did qigong exer-
cise in order to study their microchange of the superficial partial temperature by means of a
detector of human energy metabolism. The results show that before and after qigong exer-
cise
* the characteristic energy change of the superficial acupoints is related to the pathological
changes of internal organs and meridians. Their internal and external responses had repluari-
ty.
It comfirms
the characteristic energy change of New Daxi (acupoint ) provides
relevant
specificity. It
is the first time we have discovered that the detection of the loss of the specific
eneigy equilibrium of New Daxi
is a diagnostic way for tumors.

INFRARED PHENOMENA UNDER THE QIGONG STATE!
AND BLOOD VESSEL VOLUME

Chai Jianyu
Shanghai Qigong Institute .Shanghai 200030, China
Infrared phenomena under the the Chen Wenhua qigong state has been researched for
more; than ten years. This thesis, on the basis of the research
, first studies the infrared phe-
nomena under the qigong state on physiological theory
, and discusses the relationship
be-
tweerii the infrared phenomena under the qigong state and the changes of vessel volume. In or-
der tp study the
relationship between the changes
of the
infrared temperature under the
qigong state and the changes of digital vesselal volume, we observed 192 volunteers' change
of infjrared temperature and vessel volume from the pre-qigong state to post-qigong state at
the s^me time. All results indicate that the changes of the infrared temperature under the
qigonjg state were related to the changes of partial vessel volume. It also means that the ves-
sel vcjlume increaces while the infrared temperature is rising. There might be the relationship
of cause and result between the two items.
^ince the skin temperature and digital vessel volume are affected by many factors includ-
ing influence of personality
, the further research will be done on the basis of the development
of experimental techniques and more experimental samples.
