How Do Muscles Grow Scientifically Manual For Students#

Training variables, such as how often each muscle group is trained, how many exercises per muscle group you do, the number of sets and reps you do, as well as the amount of effort you put into each set, will have a big impact on the speed at which you build muscle.If youвЂ™re already practicing yoga, you donвЂ™t need exercise scientists and physiologists to convince you of the benefits of stretchingвЂ”but what about flexibility and how that relates to going deeper in your asanas? For example, when you fold into a forward bend and are brought up short by the tightness in the back of your legs, can science tell you whatвЂ™s going on? And can that knowledge help you go deeper? Knowing your body3 Mechanisms That Make Muscles Grow 1. Some training programs work better than others when it comes to building muscle. The type of training youвЂ™re doing.

Age-related muscle loss, called sarcopenia, is a natural part of aging. But men should also add loss of muscle mass to the list. The saying goes there are two certainties in life: death and taxes. Declining muscle mass is part of aging, but that does not mean you are helpless to stop it. Muscle Damage If youвЂ™ve ever felt sore after a workout, you have experienced the localized muscle damage from working.

In yoga, вЂњflexibilityвЂќ is an attitude that invests and transforms the mind as well as the body.But in Western physiological terms, вЂњflexibilityвЂќ is just the ability to move muscles and joints through their complete range. If we understand more clearly the complex physiology involved in yogic practices, we may be able refine our techniques for opening our bodies.See also Yoga for Flexibility Challenge Understanding flexibilityOf course, yoga does far more than keep us limber: It releases tension from our bodies and minds, allowing us to drop more deeply into meditation. And if you know whether any uncomfortable sensations you feel are warnings that youвЂ™re about to do damage, or whether theyвЂ™re just notices that youвЂ™re entering exciting new territory, you can make an intelligent choice between pushing on or backing offвЂ”and avoid injuries.The body relaxes in preparation for a deep sleep and starts to produce Human Growth Hormone (HGH), which increases the growth of muscle tissue and regulates the bodyвЂ™s metabolism.In addition, new scientific research may even have the potential to extend the wisdom of yoga. You can optimize your efforts if you know whether the tightness in your legs is due to poor skeletal alignment, stiff connective tissues, or nerve reflexes designed to keep you from hurting yourself. The answer to the latter questions is вЂњYes.вЂќ A knowledge of physiology can help you visualize the inner workings of your body and focus on the specific mechanisms that help you stretch.

According to Michael Alter, author of Science of Flexibility (Human Kinetics, 1998), current research demonstrates that individual muscle fibers can be stretched to approximately 150 percent of their resting length before tearing. Muscle groups operate in concert, alternately contracting and stretching in precise, coordinated sequences to produce the wide range of movements of which our bodies are capable.In skeletal movements, the working musclesвЂ”the ones that contract to move your bonesвЂ”are called the вЂњagonists.вЂќ The opposing groups of musclesвЂ”the ones that must release and elongate to allow movementвЂ”are called the вЂњantagonists.вЂќ Almost every movement of the skeleton involves the coordinated action of agonist and antagonist muscle groups: TheyвЂ™re the yang and yin of our movement anatomy.But although stretchingвЂ”the lengthening of antagonist musclesвЂ”is half the equation in skeletal movement, most exercise physiologists believe that increasing the elasticity of healthy muscle fiber is not an important factor in improving flexibility. (Physiologists divide muscles into three types: the smooth muscles of the viscera the specialized cardiac muscles of the heart and the striated muscles of the skeletonвЂ”but in this article weвЂ™ll focus only on skeletal muscles, those familiar pulleys that move the bony levers of our bodies.)The specific function of muscles, of course, is movement that is produced by muscle fibers, bundles of specialized cells that change shape by contracting or relaxing. It pulls the interwoven cellular cross-links apart and helps muscles rebuild with healthy parallel cellular structure.Remember the cheesy вЂ™60s sci-fi flick Fantastic Voyage, in which Raquel Welch and her miniaturized submarine crew get injected into someoneвЂ™s bloodstream? To really grasp how Western physiology can benefit asana practice, we need to go on our own internal odyssey, diving deep into the body to examine how muscles work.Read Anatomy of Hatha Yoga: A Manual for Students, Teachers, and Practitioners How muscles impact flexibilityMuscles are organsвЂ”biological units built from various specialized tissues that are integrated to perform a single function. Unless we stretch, we dry up and tan! Stretching slows this process of dehydration by stimulating the production of tissue lubricants. This normal aging of tissues is distressingly similar to the process that turns animal hides into leather.

It is the most abundant tissue in the body, forming an intricate mesh that connects all our body parts and compartmentalizes them into discrete bundles of anatomical structureвЂ”bones, muscles, organs, etc. ThatвЂ™s why itвЂ™s such an effective method for increasing flexibility.Connective tissues include a variety of cell groups that specialize in binding our anatomy into a cohesive whole. The first school focuses not on stretching muscle fiber itself but on increasing the elasticity of connective tissues, the cells that bind muscle fibers together, encapsulate them, and network them with other organs the second addresses the вЂњstretch reflexвЂќ and other functions of the autonomic (involuntary) nervous system. What limits flexibility?If your muscle fibers donвЂ™t limit your ability to stretch, what does? There are two major schools of scientific thought on what actually most limits flexibility and what should be done to improve it.

Anatomist David Coulter, author of Anatomy of Hatha Yoga, reflects this in his description of the asanas as вЂњa careful tending to your internal knitting.вЂќLearn more Muscular System and Ligaments of The Joints Anatomical Poster Set Flexibility 101: PaschimottanasanaNow letвЂ™s apply this physiology lesson to a basic but very powerful posture: Paschimottanasana. Of all the structural components of your body which limit your flexibility, it is the only one that you can stretch safely. Fascia is the stuff that separates individual muscle fibers and bundles them into working units, providing structure and transmitting force.Many of the benefits derived from stretchingвЂ”joint lubrication, improved healing, better circulation, and enhanced mobilityвЂ”are related to the healthy stimulation of fascia.

The instructor asks you to lift your trunk slowly, reaching out through your tailbone and up through the crown of your head, being careful not to overarch and strain your lower back as you move up and forward. Your head is resting comfortably on the floor your cervical spine is soft, but awake. Your arms are relatively relaxed, palms on your thighs. According to yoga lore, this asana rejuvenates the vertebral column and tones the internal organs, massaging the heart, kidneys, and abdomen.Imagine youвЂ™re lying on your back in yoga class, getting ready to fold up and over into Paschimottanasana.
