練習特定的瑜珈呼吸法，可以增進呼吸知能

這是一篇來自法國某大學的研究報告，實驗對象是健康的人，利用各種實驗人體的方式，測試出練習特定的瑜珈呼吸法，可以增進呼吸知能。這特定的瑜珈呼吸法包含緩慢而深度的呼吸，大約兩、三分鐘的長度，訓練期間為兩個月。

Because yoga practitioners think they are benefiting from their breath training we hypothesized that yoga respiration training (YRT) could modify the respiratory sensation. Yoga respiration (YR) ("ujjai") consisted of very slow, deep breaths (2-3 min(-1)) with sustained breath-hold after each inspiration and expiration. At inclusion in the study and after a 2-month YRT program, we determined in healthy subjects their eupneic ventilatory pattern and their capacity to discriminate external inspiratory resistive loads (respiratory sensation), digital tactile mechanical pressures (somesthetic sensation) and sound-pressure stimulations (auditory sensation). Data were compared to a gender-, age-, and weight-matched control group of healthy subjects who did not undergo the YRT program but were explored at the same epochs. After the 2-month YRT program, the respiratory sensation increased. Thus, both the exponent of the Steven's power law (Psi=kPhin) and the slope of the linear-linear plot between Psi and mouth pressure (Pm) were significantly higher, and the intercept with ordinate axis of the Psi versus Pm relationship was lower. After YRT, the peak Pm developed against inspiratory loads was significantly lower, reducing the load-induced activation of respiratory afferents. YRT induced long-lasting modifications of the ventilatory pattern with a significant lengthening of expiratory duration and a modest tidal volume increase. No significant changes in somesthetic and auditory sensations were noted. In the control group, the respiratory sensation was not modified during a 15-min period of yoga respiration, despite the peak Pm changes in response to added loads were then significantly reduced. These data suggest that training to yoga respiration selectively increases the respiratory sensation, perhaps through its persistent conditioning of the breathing pattern.

因為瑜珈開業醫生認為他們正受益於訓練的他們的氣息我們假設那瑜珈呼吸訓練(YRT)能修改呼吸感覺。 瑜珈呼吸(年)由慢組成的("ujjai")，深呼吸(2-3分(-1))有支持的氣息舉行， 每啟發和終止。 在在研究過程中的包括時候和在2個月的YRT 編程式之后， 我們在健康主題內確定他們eupneic通風圖案和區別外部吸氣電阻負載(呼吸轟動)的他們能力， 數字化的觸覺機械壓力(somesthetic 感覺)和正確壓力的刺激(聽覺)。 數據被比作性-，年齡-，以及重量比得上對照組的健康不經歷這YRT 計畫的主題， 被在相同的時代探索。 在2個月的YRT 計畫之后，呼吸感覺增加。 因此， 史蒂文的能力法律(磅因/平方英寸= kPhin)的解釋者和線線的密謀的斜坡， 磅因/平方英寸和嘴壓力(下午)相當高，以及有磅因/平方英寸與下午的有規則的軸的截距關係更低。 在YRT之后，山峰下午反對吸氣的負荷發展相當是低，降低的負荷引起的呼吸afferents的活動。 YRT 用一重要的expiratory 持續的變長引起長時間持續的這種通風的圖案的修改，一適度的潮汐體積增加。 在somesthetic方面的沒有顯著的變化和聽覺被注意到。 在對照組裡， 呼吸感覺不在一瑜珈呼吸的15最小時期期間修改，儘管山峰下午兌換，為了答覆增加負荷然後被相當降低。 這些數據表明訓練對瑜珈呼吸有選擇增加呼吸感覺，或許透過它的持久的呼吸的圖案的限制。
