GENERAL CHARACTERISTIC OF YOGA The yogic system of health involves the exercise of all types of muscles of the body (skeletal, cardiac and smooth). The associated internal pressure such as intrathoracicand intra- abdominal pressure changes form the basis of yoga system of health ..
All walk of life of people and of all ages can practice yogic exercises easily and effectively. Its main aim is to achieve the highest level of integration through the control of the modification of mind. All yogic practices are complementary to each other The nature of yogic practices is psycho- neurophysical
EXPERIENCE AFTER YOGA PRACTICE The relaxation and softening of deep inner tension and blockages; Sense of body mind equilibrium, and Feeling of energetic light-heartedness
RISK OF YOGA PRACTICES Potential to cause musculo- skeletel injury Potential to induce arrhythmias Dehydration Fluctuations of the haemodynamic parameters Thrombo- embolic phenomenon due to intimal tear resulting in stroke.
REQUIREMENTS OF YOGA Room should be well ventilated and clean Yoga should be done on an empty stomach in peace surroundings, wear clean, simple and least cumbersome . One should not speak while doing yoga All exercises should be performed with the nig attitude i.e with conscious awareness of spiritual

TYPES OF YOGIC EXCERCISES The basic yoga methods can be divided into five bar areas of practice: Asanas or body postures Pranayama or breathing exercises Purification (cleansing) practices or kiryas Music and sound therapy; and Deep relaxation
ASANAS OR BODY POSTURES Asana literally means 'posture' or 'pose’. The principle of yoga practice involves the adoption and maintenance of a particular posture of the body, which is both steady and comfortable (called psycho- physical posture). Along with controlled breathing techniques it forms the basis of Yoga's mind-body integration work
TYPES OF ASNAS SURYA NAMASKAR:- SURYA It means to greet. It is done facing the sun It energises the entire neuro- glandular and neuro- musular system of the body.
PADMASAN Benefit: This asana is primarily meant for concentration and helpful in relieving the physical, nervous and emotional problems .
HALASANA Benefits It helps to maintain flexibility of the spine. It helps to remove all gastric discomfort Itis useful in controlling the high blood sugar levels. It helps to prevent protrusion of the belly.
TRIKONASANA It makes the spine flexible and reduces the waist line
PRANAYAM OR BREATHING EXCERCISE
Purification practices or kriyas Stomach cleansing or Dhauti :- here dhauti soaked in salty water in swallowed and then pulled out . It cleans the stomach and helps in flatulence and acidity complains
(iii) Abdominal churning or Nauli - It is performed standing with knees flexed and hands resting on the thighs. After a maximal expiration, the abdominal muscles are forcefully contracted so as to form a central ridge and are then pushed in and out. Cleansing of the Head or Kapalbharti - It is performed sitting with one nostril plugged at a time while breathing in and out with the other nostril forcefully and maximally. It is essentially a hyperventilation technique. It washes of carbon- dioxide and leads to a feeling of emptiness in the head
MUSIC AND SOUND THERAPY It include rhythm and melody, combined with hand movements and sound combination. It help to develop concentration, breath coordination, communication and motor skill, as well as appreciation for the essentials of tone and harmony.
Health benefits of yoga practices
Health benefits of yoga practices The yogic practices stimulate and balance all the systems of the body. A few month practice of yoga triggers neurohormonal mechanisms
Effects on nervous system yogic practices bring about stable autonomic nervous system equilibrium with a tendency toward parasympathetic nervous system dominance. Decrease in heart rate and blood pressure (of special significance in hypertensive) Decrease in respiratory rate. (iv)Improvement in GIT and excretory functions
Improvement in sexual activity Favours storage of absorbed nutrients Decrease in oxygen consumption (fall in metabolic rate)
Effect on EEG Predominance of alpha waves; theta, delta and beta waves also increases (during various stages of meditation). Sensory attenuation ie minimal sensory input (less distraction, better concentration and pain decreases) Motor attenuation minimal motor input (comfortable posture)
Higher functions of nervous system improvement of higher intellectual activities such as emotional affects, motivation, behavior, learning efficiency, personality, memory, moral and social sense etc. Improvement in cerebral blood flow with synchronized neuronal activity
EFFECT ON CVS Heart rate and systemic BP decreases Cardiovascular efficiency increases This may be attributed to increase baroreflex sensitivity.
EFFECT ON RESPIRATORY SYSTEM Respiratory rate decreases Tidal volume increases Vital capacity increases Breath holding time increases Maximum breathing capacity (MBC) increases Respiratory efficiency increases and respiration become more smooth.
EFFECT ON METABOLIC RATE Yogic exercises slow down metabolism by decreasing the oxygen consumption. The fall in the metabolic rate is much greater and more steep than during sleep. Higher maximum oxygen consumption can be achieved due to increase in cardio- respiratory efficiency.
EFFECT OF NEUROHORMONAL ACTIVITY (i) Decrease in urinary exertion of catecholamines (epinephrine, nor-epinephrine and dopamine); aldosterone. (ii) Serum catecholamines, testosterone and luteinizing hormone levels decreases (ii) Increase in the urinary excretion of cortisol. (iv) Thyroxine increases (v) Oxytocin increases
vi) Prolactin increases (v) Decrease in resting glucocorticoid levels (viii) Decrease in fasting blood glucose level
EFFECT ON SKELETO- MUSCULAR SYSTEM E.M.G. activity decreases Musculoskeletal flexibility and joint range of movement increases Strength and resiliency increases Endurance increases Energy level increases
EFFECT ON DIGESTIVE SYSTEM Increase blood flow to GIT Stimulate peristalsis Relax digestive system and leads to more effectre elimination.
PSYCHOLOGICAL BENEFITS Somatic and kinesthetic awareness increases Mood improves and subjective well being increases Social adjustment increases Anxiety and depression decreases Hostility (unfriendliness) decreases
6. Psychomotor functions improves such as Grip strength increases Fine skill movements improves 7 . Endurance increases 8. Integrated functions of body parts improves
BIOCHEMICAL BENEFITS biochemical The ant antioxidant generative profile improves indicating an. antistress effect important in the prevention of diseases. Haematocrit, haemoglobin and lymphocyte count TLC decreases Total serum protein and v vitamin C increases Clucose and sodium levels decreases
Lipid profile:- Total cholesterol decreases Triglycerides decreases LDL and VLDL decreases HDL increases .
Yoga has been found to be particularly helpful in the management of obesity. By practicing yoga for a year help significant improvement in the ideal body weight and body density. 1.Obesity and Body Weight YOGA IN HEALTH AND DISEASE
MECHANISMS (i) By simple ,excess calorie expenditure (ii) Life style modification (iii) Improvemient in dietary habits (iv) Positive body-mind equilibrium 2. Hypertension A short period (3 months) of regular yogic practice for 1 hr / day is effective in controlling blood pressure in such individuals. I MECHANISM (i) Restoration of baroreflex sensitivity with autonomic readjustments.
3. Coronary Artery Disease (CAD) / lschaemic Heart Disease (IHD ) Reduced heart rate variability and baroreflex sensitivity are powerful predictors of CAD/IHD. Further increased intrinsic neurohormonal activity due to general stress in life also contributes to increased risk of myocardial infarction.
4. Diabetes Mellitus Maturity onset diabetes can usually be controlled through dietary life style changes. I t can bring lifestyle changes necessary to keep diabetes symptoms in check. Yoga exercises tone and shape the body, improve posture and circulation (specially to the extremities) and contribute to feeling of well-being. It helps to reduce the frequency of· hyperglycemia and need for oral hypoglycemics to.a maintain adequate blood sugar levels.
5. Skeleto - muscular disorders Yoga has been beneficial for skeleto - muscular disorders such as backache, spondolytis (cervical/lumbar), arthritis etc. Asanas strengthen back muscles and relieve backache. They also help reliving muscular spasm by increasing flexibility, decrease in body weight and stress, and producing relaxation of the body as a whole.
