The effects of breathing with mainly inspiration or expiration on pulmonary function and chest expansion

Abstract

[Purpose] This study aimed to determine the effects of inspiration- and expiration-oriented breathing on pulmonary function and chest expansion. [Subjects and Methods] Twenty healthy male university students were divided randomly into inspiration-oriented and expiration-oriented breathing groups. Their pulmonary function and chest size during inspiration or expiration were evaluated and then re-evaluated after 15 minutes of breathing exercise five times a week for four weeks. [Results] The breathing with mainly inspiration group (BMIG) showed significant differences in chest size during inspiration (CSI), chest expansion values (CEVs), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF) after four weeks. The breathing with mainly expiration group (BMEG) showed significant differences in all measured variables except CSI. Comparison of the groups after exercise showed that the BMEG demonstrated differences from the BMIG in chest size during expiration (CSE), CEV, and PEF. Comparison of the changes in variables after exercise showed that the BMEG demonstrated significantly different changes in CSE, CEV, FEV1/FVC, and PEF. The BMIG showed a significantly different change in FVC. [Conclusion] Although both groups demonstrated improvements in pulmonary function and chest expansion, inter-group differences were observed. Therefore, inspiration- or expiration-oriented breathing may be recommended differently according to the desired outcome.

Effectiveness of LiuZiJue Qigong versus traditional core stability training for poststroke patients complicated with abnormal trunk postural control: study protocol for a single-center randomized controlled trial

“…In subsequent studies, it was also found that "abdominal electromyography decreased during forced exhalation" [10]. Patients with cerebral apoplexy generally have abnormal breathing, which is often manifested as decreased exhalation ability [11]. Because of all these factors, proper breathing exercises, especially exhalation exercises, are necessary in patients with stroke [12].…”

Respiratory Disorders: Physiology and Patient Problems

“…These disorders are characterising of lot secretion production and a long remission period without episodes [4,5]. The physiology of these respiratory disorders is related to the mechanism of respiration difficulties, as in inspiration, as in expiration ways, changing until obstructive to restrictive effects [4][5][6][7].…”

“…In the inspiration mode there are some disorders mainly obstructive diseases and asthma [4,5,7]. The physiology of the inspiration movement is described in a lot of books about respiratory system and in articles [6,8,9]. In the expiration mode there are a few disorders mainly restrictive diseases as bronquiectasias and lung abscess [4,6,10,11].…”
