Exercise physiology is the study of physical responses and adaptations to several types of physical exercise. It helps professionals understand how the body works and it can help you become more physically healthy. If you wish to push up your physical fitness a notch, all you need is exercise physiology. Our fitness expert Akshay Chopra tells us what are the principles of exercise physiology.

The Theory of Biorobs: Towards the Future part II was held during BioVision Alexandria 2010 conference "New Life Sciences: Future Prospects" on Tuesday, 13 April 2010 at the Bibliotheca Alexandrina Conference Center Great Hall. The session was moderated by Dr. Ismail Serageldin, Director of Bibliotheca Alexandrina and featured distinguished robotics scientist Prof. Miguel Nicolelis, Anne W. Deane Professor of Neuroscience and Professor of Neurobiology, Biomedical Engineering and Psychology, Duke University, USA. Prof. Nicolelis presented "Principles of Neural Ensemble Physiology" where he reviewed series of recent experiments demonstrating the possibility of using real-time computational models to investigate how ensembles of neurons encode motor information
Paramahamsa Nithyananda continues intercepting the first verse or mantra of the Kenopanishad, the second primary Upanishad in Nithya Satsang from Varanasi on 12th July 2016. Illuminating the pure beauty of Upanishads, He explains that the ‘pure questioning’ in the form of poetry reveals to us the amazing renunciation with extraordinary romance – which is both masculine and feminine principles in their wholeness. He points out the powerful lies taught to us that – if you are logical, rational, you cannot be poetic, if you are masculine, you cannot be feminine. By doing so, our muscle memory is denied certain ability to flow and we deny our other part. We need to grow with the natural principles of male and female physiology, carrying the consciousness based understanding, and not the societal conditionings which are the wrong beliefs that suppress one part of us. He gives the lesson for Nithyananda Gurukuls – Do not brand your body as male or female and constantly program it. Let it function with the male and female qualifies naturally, freely. The topic for Spiritual Discussions and Exploration, called ‘Vaakyartha Sadas’ in Samskrit is – “Meditate today on the pure inner space where the masculine and feminine principles exist but not the social conditioning of being male and female. The natural principles of being male and female and social conditioning of masculine and feminine concepts. What are the natural physiological principles and what are the social conditioning?

What is COMPARATIVE PHYSIOLOGY? What does COMPARATIVE PHYSIOLOGY mean? COMPARATIVE PHYSIOLOGY meaning - COMPARATIVE PHYSIOLOGY definition - COMPARATIVE PHYSIOLOGY explanation. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Comparative physiology is a subdiscipline of physiology that studies and exploits the diversity of functional characteristics of various kinds of organisms. It is closely related to evolutionary physiology and environmental physiology. Many universities offer undergraduate courses that cover comparative aspects of animal physiology. According to Clifford Ladd Prosser, "Comparative Physiology is not so much a defined discipline as a viewpoint, a philosophy." Originally, physiology focused primarily on human beings, in large part from a desire to improve medical practices. When physiologists first began comparing different species it was sometimes out of simple curiosity to understand how organisms work but also stemmed from a desire to discover basic physiological principles. This use of specific organisms convenient to study specific questions is known as the Krogh Principle. C. Ladd Prosser, a founder of modern comparative physiology, outlined a broad agenda for comparative physiology in his 1950 edited volume (see summary and discussion in Garland and Carter): 1. To describe how different kinds of animals meet their needs. This amounts to cataloging functional aspects of biological diversity, and has recently been criticized as "stamp collecting" with the suggestion that the field should move beyond that initial, exploratory phase. 2. The use of physiological information to reconstruct phylogenetic relationships of organisms. In principle physiological information could be used just as morphological information or DNA sequence is used to measure evolutionary divergence of organisms. In practice, this has rarely been done, for at least four reasons: physiology doesn't leave many fossil cues, it can't be measured on museum specimens, it is difficult to quantify as compared with morphology or DNA sequences, and physiology is more likely to be adaptive than DNA, and so subject to parallel and convergent evolution, which confuses phylogenetic reconstruction. 3. To elucidate how physiology mediates interactions between organisms and their environments. This is essentially physiological ecology or ecological physiology. 4. To identify "model systems" for studying particular physiological functions. Examples of this include using squid giant axons to understand general principles of nerve transmission, using rattlesnake tail shaker muscles for measurement of in vivo changes in metabolites (because the whole animal can be put in an NMR machine), and the use of ectothermic poikilotherms to study effects of temperature on physiology. 5. To use the "kind of animal" as an experimental variable. "While other branches of physiology use such variables as light, temperature, oxygen tension, and hormone balance, comparative physiology uses, in addition, species or animal type as a variable for each function." 25 years later, Prosser put things this way: "I like to think of it as that method in physiology which uses kind of organism as one experimental variable." Comparative physiologists often study organisms that live in "extreme" environments (e.g., deserts) because they expect to find especially clear examples of evolutionary adaptation. One example is the study of water balance in desert-inhabiting mammals, which have been found to exhibit kidney specializations. Similarly, comparative physiologists have been attracted to "unusual" organisms, such as very large or small ones. As an example, of the latter, hummingbirds have been studied. As another example, giraffe have been studied because of their long necks and the expectation that this would lead to specializations related to the regulation of blood pressure. More generally, ectothermic vertebrates have been studied to determine how blood acid-base balance and pH change as body temperature changes. In the United States, research in comparative physiology is funded by both the National Institutes of Health and the National Science Foundation.
