Effect of four voluntary regulated yoga breathing techniques on grip strength
1Swami Vivekananda Yoga Research Foundation, Bangalore, India.
Abstract:
Bilateral hand-grip strength was studied in 21 male volunteers (M age = 25.6 yr., SD = 5.2). All were assessed before and after five practice sessions of 20 min. duration: right-nostril yoga breathing, left-nostril yoga breathing, alternate-nostril yoga breathing, breath awareness, and a no-intervention session. Data were analyzed with analyses of variance and an analysis of variance using the no-breath awareness control condition as a covariate. There were no significant changes. The left-hand-grip strength reduced after left-nostril yoga breathing. However, findings were not considered significant, so methodological issues in yoga research which could contribute to null findings and even mask actual changes were discussed.

Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...
Mechanism of Breathing III: The Accessory Muscles
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...
