Backward Bending Asana's Physiology | Nirmala Institute of Yoga & Health



Dear friends ! In this video we are going
to discuss about backward bending asan with physiological explanation. Friends, usually our daily activities are
often associated with forward bending. We seldom bend back for any reason. In order to maintain health, our body requires
backward bending also. Backward bending postures reposes and strengthens
the entire nervous system along with vital organs of the body. They also re-energises the muscles and regulates
metabolism of the body. So let us see how these backward bending asanas
works ? Backward bending asan with digestive and nervous
system: Encourages good digestion: Good digestion refers to efficient working
of gastrointestinal tract. Backward bending asan increases the rate of
peristalsis movement in the stomach, small intestine and large intestine. These asanas pushes the intestinal contents
in the anal direction before slowing down and allows the intestinal contents to be propelled
more quickly and easily towards anus. As a result the digestion becomes fast and
efficient. In this way backward bending asanas encourages
good digestion. Reduces abdominal fat: Due to lack of physical activity, poor dietary
habits and stress, the entire digestive system becomes sluggish. In that condition disproportionate amount
of fat is unevenly accumulated in the abdomen region. Backward bending asanas are associated with
stretching of abdominal muscles which requires strength and energy to perform. For that purpose, body begins to consume stored
fat from the abdominal region by converting it into glycerol and fatty acids also. Glycerol is converted to glucose; then further
break down releases energy; as well as fatty acids are broken down into hydrogen and carbon
dioxide which also releases energy. This energy is utilised by muscles for contraction
and movement. In this way, backward bending asanas reduces
abdominal fat. Alleviates lower back pain: When stagnant stools are accumulated in the
large intestines, then the process of absorption becomes slow. This decreases intestinal absorption of dietary
vitamins and minerals. Shortage of vitamins and minerals leads to
decrease the rate of depolarization in the membrane potential within the cell and slowly
generates action potential. This results weak nerve impulse transmission
to muscles which provokes pain in lower back as it is proximal to large intestine also. Backward bending asanas stretches the abdominal
muscles which pushes the stagnant stools towards rectum and relieves from constipation. In this way, backward bending asanas alleviates
lower back pain. Relieves from lumbar slip disc: Intervertebral discs are the soft tissues
containing nucleus pulposus at the center and anulus fibrosus surrounding the center
with certain thickness located between the adjacent vertebrae. The range of movement of the vertebral column
is limited by the thickness, elasticity, and compressibility of the Intervertebral discs. These also act as shock absorbers. In Over weight and heavy lifters, the pulpy
nucleus flattens and the anulus bulges when weight is applied, as occurs during standing
and more so during lifting. Due to excessive forward movements, the nucleus
pulposus serves as a support and the anulus is simultaneously placed under compression
slides to one side. Backward bending asanas reduces pain and relocates
the position of the central part of the disc with sustain flexions of the vertebral column. In this way backward bending asanas relieves
from lumbar slip disc. Backward bending asan with other system:
Promotes proper functioning of kidneys: Backward bending is a natural range of motion
for the spine which increases its suppleness and flexibility. This involves compression and stimulation
of internal organs like kidneys which are located just below the ribs at the back and
posterior to abdomen. Gentle compression and pressure on kidneys
provides opportunity to filter the blood in an effective way and regulates major hormones
secreted by adrenal glands. In this way backward bending asanas promotes
proper functioning of kidneys. Relieves from menstrual discomforts:
Usually; menstrual discomforts are associated with abdominal cramps, lower back pain also. These arise due to excessive contraction in
the uterus to get rid of uterine lining by limiting the supply of oxygen to the nearby
muscles, which radiate pain through the web of nerves within pelvic region. During backward bending asanas extension occurs
in the frontal plane of abdominal area which covers abdomen and pelvic region. This encourages optimum blood supply to the
pelvic region which nourishes the reproductive organs, urinary bladder and lower part of
intestines. In this way these asanas relieves menstrual
discomforts. Releases muscular tensions of back and legs: The condition in which the muscle length shortens
and the tension on the muscle remains constant throughout contraction refers to muscular
tension. It is usually associated with stress, anxiety
and sedentary life style. Backward bending asanas like dhanurasana exerts
sustain pressure on regions of lower back from L1 to S1 area which innervates pelvic
organs and legs. These asanas elongates the contraction of
muscles and propels proper blood flow throughout the of the back and legs which provides high
relaxation to the muscles. In this way backward bending asanas releases
muscular tensions. Eliminates chest congestion: Due to prolong improper sitting postures,
the entire thoracic cavity is compressed and the breathing becomes shallow. This causes lack of proper oxygen supply to
the lungs arousing a feeling of tightness i.e. chest congestion along with other allied
problem also. Backward bending asanas like ustrasana and
chakrasana expands the rib cage, stretches the diaphragm and allows air into lungs freely
and deeply. Due to expansion of muscles of chest, diaphragm
and ribs, they support deep breathing which delivers more oxygen supply to lungs instead
of shallow breathing. In this way backward bending asanas increases
chest expansion, improves efficiency of respiratory muscles and eliminates chest congestion. Thank you so much for watching this video. If you like this video then please subscribe
