Joint Complexes and Muscle Groups Used in Yoga

There are hundreds of muscles and joints in the human body, so when thinking about the structure of yoga, it is helpful to think of the nine major joint complexes and opposing muscle groups. Joint complexes are sets of joints that work together in the body and behave as one joint. The nine major joint complexes are the ankles, knees, elbows, wrists, shoulders, neck, lower back, upper back, and hips. A muscle group is a group of muscles that perform the same job at a joint complex. When stretching a muscle group, you must consider the opposing muscle group, the group of muscles that are opposing the action of the muscles being stretched. This is because muscle groups work as opposing pairs. Lengthening one muscle group will result in the opposing one being shortened.

Spinal Reflexes As They Relate to the Structure of Yoga

In the structure of yoga, you must also consider the spinal reflexes. A spinal reflex is when a nerve impulse is passed into the spinal cord and then a responding message is sent out without brain input. The three spinal reflexes in yoga are:

• The Myotatic Reflex – this is the stretch reflex. This reflex causes a lengthened muscle group to become tense if it is suddenly stretched, therefore, you need to block this reflex in yoga when trying to stretch. The reflex can be blocked by mentally focusing on the muscle group being stretched, exhaling as you move slowly into a stretch using the shortened muscles to actively move the joint complex into position.

• The Reciprocal Relaxation Reflex – this reflex causes the stretched muscle group to relax when the shortened muscle group is tensed. It can be used to help you relax and stretch any part of your body.

• The Inverse Myotatic (Relaxation) Reflex – this reflex causes the stretched muscle group to relax if it is stretched enough. It usually occurs after at least 12 to 15 seconds.

Yoga burns on average about 200 calories per hour, but it really depends on the type of yoga you practice. Also, learning how to intensify your practice and challenging yourself personally during class can really add to the total calories burned.

Different Types of Yoga Popular in the West:

Try this for half an hour!

Hatha Yoga

An easy-to-learn basic form of yoga that has become very popular in the United States. Hatha Yoga is the foundation of all Yoga styles. It incorporates Asanas (postures), Pranayama (regulated breathing), meditation and kundalini into a complete system that can be used to achieve enlightenment or self-realization if practiced on a regular basis. It has become very popular in America as source of exercise and stress management. The ideal way to practice the Hatha Yoga poses is to approach the practice session in a calm, meditative mood. Sit quietly for a few moments, then begin the series, slowly, with control and grace, being inwardly aware as the body performs the various poses selected for the practice session. Do not overdo the asanas or try to compete with others.

A gentle form a Yoga, the most common form that focuses on basic postures that flow in and out with emphasis on breathing techniques. Hatha Yoga is what most people in the West associate with the word “Yoga” and is practiced for mental and physical health. This is a great intro to yoga for beginners.

Iyengar Yoga

Developed by yoga master B.K.S. Iyengar more than 60 years ago, promotes strength, flexibility, endurance, and balance through coordinated breathing and poses that require precise body alignment. The poses are generally held longer than in other styles of yoga. In Iyengar, you slowly move into a pose, hold it for a minute or so, and then rest for a few breaths before stretching into another. Equipment like cushions, blankets, straps, and blocks to help the less flexible also distinguishes Iyengar from other types of yoga.

Although Iyengar incorporates the traditional postures, or asanas, that make up the broader category of hatha yoga, the cushions and other props revolutionized yoga by enabling everyone — even the elderly, sick, and disabled — to practice. Because of its slow pace, attention to detail, and use of props, Iyengar yoga can be especially good if you’re recovering from an injury. Iyengar is still one of the most popular types of yoga taught today. If you are restricted by age or a previous injury then Iyengar will be gentle enough for your needs. These yoga classes incorporate blankets, cushions and straps into the poses to make them easier to accomplish. the downside is that Iyengar classes don’t have the same feeling of flow that other styles have since there is a lot of time spent setting people up in poses and it doesn’t have the same group energy that a vinyasa or even hot yoga class since it will seem more disjointed.

Vinyasa Yoga

A dynamic form of yoga that connects postures and creates a flow between traditional yoga postures. The ‘Vinyasa flow’ is used especially during the Sun Salutation series. many types of Power Yoga, Hot Yoga and even Astanga also have elements of Vinyasa Yoga with the beginning sequence.

Bikram and Hot Yoga

The method of yoga that is a comprehensive workout that includes all the components of fitness: muscular strength, muscular endurance, cardiovascular flexibility and weight loss. The founder, Bikram Choudhury, was a gold medal Olympic weight lifter in 1963 and is a disciple of Bishnu Ghosh, brother of Paramahansa Yogananda, (Autobiography of a Yogi). One of the unusual but most beneficial aspects of Bikram’s yoga practice is the 95-105 degree temperature which promotes more flexibility, detoxification, and prevention of injuries. Classes include 26 postures, guided by specific dialogue and breathing techniques.

This is the only yoga style that specializes in using the heated environment. The idea is that muscles will loosen and sweating will cleanse the body and remove symptoms of disease and chronic pain. To my knowledge, there hasn’t been any research on the safety or efficacy of Bikram, and so I don’t recommend it to beginners or those with serious cardiovascular medical concerns because of the potential risk of dehydration, blood pressure changes, and cardiac problems with exertion in such an extreme environment. This is particularly so for individuals who may have an existing heart problem or high blood pressure but don’t know it. People who do it swear by it, and so if you are determined to try it, I recommend that you speak with your physician first.

If you want an intensive yoga experience that incorporates a comprehensive yoga workout with a yoga studio heated up to 105 degrees than Hot Yoga or Bikram is probably what you’re looking for. This method of yoga promotes flexibility, strength, endurance, weight loss and body detoxification. It is not for the faint of heart. It requires incredible willpower and commitment to just stay in the room when it is that hot.

Ashtanga Yoga

Ashtanga is designed to build strength and endurance. It is an aggressive workout where you move quickly from one pose to another. There is little emphasis on meditation with Ashtanga, and at the end of the session you will feel more like you have completed a traditional weight training or calisthenic workout than you would with any other type of yoga. Ashtanga is for you if you’re looking for a tough, physically challenging workout and you want to get that sculpted toned look. The eight limbs connoted by the word ‘Ashtanga’ refer specifically to the eight spiritual practices outlined by the Yoga Sutra, the original Yoga text. Ashtanga can be composed of 6 set series, each increasing with more difficulty. It is usually combined or referred to as Ashtanga. People who do it swear by it, and so if you are determined to try it, I recommend that you speak with your physician first. This is not a good type for beginners or for those who are not already in good shape to begin with.

Power Yoga

A recently-developed yoga method that was established in the United States. It is an intense yoga workout that focuses on fast-paced, advanced yoga poses meant to build power and work your body harder.

Power yoga is essentially yoga with brawn. It’s the American interpretation of Ashtanga yoga, a discipline that combines stretching, strength training, and meditative breathing. But power yoga takes Ashtanga one step further. Many of the poses resemble basic calisthenics — push-ups and handstands, toe touches and side bends — but the key to power yoga’s sweat-producing, muscle-building power is the pace. Instead of pausing between poses as you would in traditional yoga, each move flows into the next, making it an intense aerobic workout.

Jivamukti Yoga

Developed in 1986 by Sharon Gannon and David Life, the Jivamukti Yoga method expresses the spiritual and ethical aspects of the practice of yoga that have been disregarded or devalued in contemporary times. It is a vigorous and challenging practice with an emphasis on scriptural study, Sanskrit chanting, vegetarianism, non- violence, meditation, devotion to God and the role that music and listening play in the practice of yoga.

Life and Gannon currently operate a few popular yoga studios in New York City. There are elements of power and vinyasa yoga in a typical class. The classes tend to be very crowded as well.

Kundalini Yoga

The practice concentrates on awakening the energy at the base of the spine and drawing it upward. In addition to postures, a typical class will also include chanting, meditation, and breathing exercises. Poses are held for a long time with very repitive movements and chants. I would not recommend this to a beginner since the overtly spiritual aspects and chanting can turn off someone that is very religious.

Restorative Yoga

If you want a relaxing yoga experience then restorative yoga classes might be what you’re after. This yoga method incorporates blankets, blocks and yoga bolsters into the class and focuses on relaxation rather than an intensive workout. This is great for those that are feeling depleted and have physical limitations that would prevent them from trying the more vigorous kinds of yoga. This is a great practice for those that have serious illnesses and are worried about a fast paced athletic kind of practice. This is also a great intro to yoga if you do not think you can get into crazy poses and worried about keeping up with a more athletic class. You are not going to get a six -pack from this kind of practice though.

If you are restricted by age or a previous injury then Iyengar or Restorative will be gentle enough for your needs. These yoga classes incorporate blankets, cushions and straps into the poses to make them easier to accomplish. The only downside is that is it tricky to replicate the class at home since it is very prop intensive. You could always invest in the props and then do the practice at home.

Key differences between Hatha Yoga And Vinyasa Yoga

There are various different types of yoga, some more advanced than others, but all work towards the same goal. That is, they all seek to unify the mind, spirit, and body; and to increase strength and flexibility. Poses are emphasized when the body is out of shape, in need of healing, or not flexible enough. The different styles of yoga, however, approach the practice of asanas in individual ways.

Two of the most popular styles of yoga used today are Hatha Yoga, and Vinyasa Yoga. Although vinyasa yoga is derived from hatha yoga, classes are very different. One of the features that make it unique is the pace. Another is the way postures are linked together in a series of movements. This produces effects in the body, especially in the cardiovascular system, that a moderate hatha yoga class does not.

Hatha Yoga is a gentle and slower paced form of yoga, although it can be quite challenging physically when you move deeper into the practice of it. The word Hatha, when split in to ‘ha’ and ‘tha’, means ‘sun’ and ‘moon’. This style is ideal for those that are new to yoga, and haven’t yet built up experience or confidence. Due to its’ slower pace, it is easier for people to learn the principles, postures, and the breathing methods involved in yoga.

Vinyasa Yoga, on the other hand, is a far faster paced, and more advanced form of yoga. Instead of simply doing individual exercises on the mat, with pauses in between, the asanas are linked together in synchronization with the in-flow and out-flow of breath. This produces a very dynamic effect, and it allows heat to build up in the body. An increased body temperature helps loosen the muscles, and people find they can go deeper into a stretch than if they were doing the posture in a more traditional way.

Both Hatha and Vinyasa yoga offers a range of health benefits. There is certainly no reason why you cannot start off using the slower paces Hatha Yoga, and once more experienced and flexible, move on to practice the more challenging form of yoga, Vinyasa. Both offer a great way to increase mobility in the joints, tone up your body, and find a sense of peace and stillness often lacking in daily activity
