This study quantifies cardiorespiratory and metabolic responses during fast and slow Surya Namaskar (SN). Slow SN shows lower physiological strain, with posture changes significantly impacting oxygen consumption and ventilation.
Area of Science:
- Yoga and Exercise Physiology
- Cardiorespiratory and Metabolic Health
Background:
- Surya Namaskar (SN) is a popular 12-posture yogic sequence with an unclear rationale.
- Limited research exists on posture-specific physiological changes during SN at varying paces.
Purpose of the Study:
- To quantify cardiorespiratory and metabolic responses during fast SN (FSN) and slow SN (SSN) posture by posture.
- To model the dynamics of physiological parameter changes across the SN sequence.
Main Methods:
- A self-as-control study involving 20 healthy males performing FSN and SSN.
- Continuous monitoring of heart rate, oxygen consumption (VO2), minute ventilation (VE), and respiratory quotient (RQ) using specialized equipment.
Main Results:
- Slow SN elicited significantly lower heart rate, VO2, VE, and fat utilization, with a higher RQ compared to FSN.
- Heart rate remained stable across SN paces, while other parameters showed greater variability.
- Postural changes significantly influenced VO2 and VE, but less so for heart rate, RQ, and fat utilization.
Conclusions:
- Distinct physiological rhythms observed in posture-by-posture analysis may inform the rationale behind the SN sequence.
- Results can guide yoga practitioners and instructors in tailoring SN sessions for specific goals.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Exercise and Cardiac Output
Sustained exercise increases the muscles' oxygen demand, which can be met...
Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...
Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...
