Effect of Regular Yogic Training on Growth Hormone and Dehydroepiandrosterone Sulfate as an Endocrine Marker of Aging

Growth hormone (GH) and dehydroepiandrosterone sulfate (DHEAS) secretion decline with advancing age and are associated with the symptoms of aging. Yogic texts claimed that regular practice of yoga may restore and maintain general endocrinological properties in the human body. Objective of the Study. To observe the effect of yogic training for twelve weeks on basal level of GH and DHEAS in middle aged group. Method. Forty-five untrained volunteers were divided into two groups, that is, yoga practicing (experimental: male 15, age 42.80 ± 7.43 yrs; female 8, age 44.75 ± 8.40 yrs) and waitlisted control group (male 15, age 41.67 ± 7.87 yrs; female 7, age 45.43 ± 7.00 yrs). The experimental group underwent combined yogic practices daily in the morning for 6 days/week for 12 weeks, whereas control group continued their usual routine activities. Standing height, body weight, body mass index, and basal level of GH and DHEAS were measured before commencement and after six and twelve weeks of yogic training period. The repeated measure ANOVA was used for data analysis. Results. 12 weeks of yogic training produces a significant increase in GH and DHEAS for both male and female groups as compared to their baseline data, whereas no as such changes were observed in the control group. Conclusion. Combined approach of graded yogic training may be beneficial for maintaining the basal level of GH and DHEAS in the human body, thus promoting healthy aging.

EXERCISE EFFECT ON NEUROPSYCHOLOGICAL FUNCTION - A REVIEW

Research documented that regular participation in physical exercise has a beneficial influence on various aspects of brain function. Human studies reported that cognition and mental performance can be improved with various types of exercise like aerobic exercise, resistance exercise and others. Participations in exercise not only improve the physical health, but also improve their academic performance, job/office performance, reduce illness and injury related to age related decline and also improve sports performance. This article features with the positive effects of exercise on cognition and brain function, at the molecular, cellular systems and behavioral levels. More research investigation on exercise related benefits for specific components of brain and cognitive function is clearly needed in all cross section of human population.

Effect of Physical Exercise on Female Hormone

Evidence suggested that exercise may change, level of secretion of female hormones such as: Prolactin, Luteinizing, Follicle Stimulating, Estrogen and Progesterone. The researcher intends to concentrate on the function of various female hormone with sources of secretion, method of hormonal test and various problems of female. The prolactin hormone is secreted from anterior pituitary gland and its main function is milk secretion. Pituitary gland secreted Luteinizing hormone and complete development of ovarian follicle to secretary stage and secretion of estrogen are maintained by this hormone. Sources of follicle stimulating hormone is the anterior pituitary hormone gland and its work is regulating of human reproductive system, progesterone and menstrual cycle. Estrogen is secreted form ovary and it is responsible for puberty changes, proliferation stages of menstruation, growth of uterus during pregnancy, exert synthesis action with oxytosin. Progesterone hormone comes from Carpus lutem, Placenta, Adrenal Cortex and it is responsible for premenstrual change of uterine mucosa. One of the best hormonal tests for basal level of PRL, LH, FSH, estrogen and progesterone is Chemiluminescence immunoassay (CLIA). Following an overnight fasting venues blood sample were taken via a disposable plastic syringe inserted into an antecubital forearm vein. Blood (3ml) was allotted to colt for one hour in a plain test tube(burocell) and then centrifuged (REMI) at 30o Celsius for 5 minutes at 6000 rev min -1 to separate the serum form the cell before proceeding with CLIA test. Infertility, irregular menstrual cycle, decreases in sex drive, unable to breast feeding after child birth are the common problem due to imbalance in female hormonal secretion.
