It is well known that respiratory exercises have many beneficial effects. They improve the

abdominal breathing and the function of the respiratory muscles, so the respiration becomes more

effective. The more effective breathing provides better oxygen supply for the peripheral tissues. By

the way the mobility of the chest as well as the whole respiratory mechanism will be improved.irculation becomes better by the increase in cardiac output. !ltogether the respiratory exercises

help to keep a pleasant daily lifestyle, create the vegetative balance. It was supposed that the

respiratory exercises can result in the improvement of physical stress tolerance and increase incardio"respiratory endurance. The aim of our experiments was to examine the effects of respiratory

exercises on the chest mobility and aerobic endurance. The circumferences of the chest at three

different locations, the voluntary apnoea time #$% and the results in ooper test were measured &. Ifthe hypothesis that respiratory exercises have positive effect on the aerobic endurance would be

proved, the endurance of patients who are excluded from cardiovascular endurance training on

account of contraindication could be improved.

2 clients took part in the investigations. The age of participants was 27.89$.2 years in average

:mean9+;), nmale was 27>2.

/e used a self"constructed 0uestionnaire for mapping the risk factors and the knowledge ofparticipants about respiratory exercises. The thoracic circumference of participants was determined

at three different levels by using a measuring tape> in the axillary region, at the level of the nipples,and at the level of the rib $&. The difference in circumference at the end of the maximum expiration

and inspiration was taken as the measure of chest motility. /e also measured the duration of thevoluntary apnoea :breath"hold time= as the indicator of the physical endurance. The examiner asked

the participants to make a forced expiration, then to inspire at maximum amplitude and hold the air

in. The process was repeated three times and the best result was used. To characteri4e the aerobicendurance the result in ooper test was also measured, that is the distance performed by running in

$2 minutes. Then we carried out a training programme containing respiratory exercises in a ?"week

period, twice a week. (uring the training programme the participants have done common respiratoryexercises in different body positions. /e used hardened positions, and the movements of the arm

aimed to increase the movement of the chest. !t the end of the training programme we asked the

participants to fill in a second 0uestionnaire about their sub@ective opinions regarding the wholeprocedure and we measured the parameters mentioned before again.

+tatistical analysis was performed by )icrosoft ;xcel. The significance was evaluated by paired t"

test.

The evaluation of 0uestionnaires at the end of the intervention programme revealed the positive

effects of respiratory exercises not only on the physical but on the psychic status, too.

(i$#inThe respiratory exercises used for a long while in the physiotherapy are based on the Hprana@ama in

the yoga &. The ma@ority of people get accustomed to inappropriate breathing techni0ues in spite ofthe fact that the suitable respiration facilitates other vital processes as the circulation, the neural

regulation etc. The right breathing techni0ue improves the function of the diaphragm, decreases the

J2and energy re0uirements of the respiratory muscles, so increases the efficiency of breathing. It issupposed that these changes are manifested in the improvement of the aerobic endurance and the

physical loadability.

Jur data showed a significant increase in the mobility of the chest which could result in an increasein the tidal volume and the vital capacity. The duration of the voluntary apnoea was elongated on the

effect of respiratory exercises. The voluntary apnoea can be used as an indicator of aerobic

endurance &, since the better the oxygen consumption, the longer the breath"hold time, the greaterthe aerobic endurance. The performance in the running ooper test showed remarkable correlation

to the duration of voluntary apnoea. +ince the breath"hold time seems to be improvable by

respiratory exercises these findings can be valuable in the improvement of endurance in elder age or

in the pathological conditions when the intensive endurance improving trainings are contraindicated.

Cn$l#in

The respiratory exercises can be effective tools for improvement of physical endurance and

performance for preventive and also curative purposes.
