Muscles generate heat and force for movement, help us breathe, and keep our bodies upright. Skeletal muscle tissue is composed of two fibres, actin (thin fibres) and myosin (thick fibres). These two fibres give the muscle a striated appearance. In order for muscle to contract nerves called motor neurones must first stimulate it. A single motor neurone and the muscle fibres stimulated by it are called a motor unit. The recruiting motor units play a large part in the force of the muscle during contraction. The more motor units (muscle fibres) recruited the stronger the force of contraction.
Muscle fibres are classified as Type I, Type IIa and Type IIb fibres. "Fast" and "slow" twitches are also two other classifications for muscle fibres. Type I fibres (slow twitch) fibres are more resistant to fatigue than Type IIa or IIb fibres and have a high capacity for aerobic metabolism, fatigue faster and are mainly anaerobic.
Slow twitch fibres are mainly for endurance while fast twitch is for speed and performance. A muscle will generally have an equal amount of both fast and slow twitch muscle fibres. In regards to hypertrophy (muscle growth), fast twitch fibres grow faster and larger than slow twitch. Within the fast twitch muscle fibres, type IIa fibres are considered intermediate between fast and slow twitch fibres in relation to speed and contraction. For example, Type IIa fibres can become more glycolytic or aerobic depending on the type of training an athlete performs. If an endurance runner were to stop running and start weight lifting, then his or her Type IIa fibres would become more glycolytic in order to handle the stress of the activity.
Muscle growth and endurance is an adaptation to stress. For example, a sprinter will develop large quadriceps and hamstrings in order to adapt to the stress, while an endurance runner will develop more endurance to efficiently handle the stress. Type I muscle fibres respond to stress by becoming more efficient and stronger with slight hypertrophy, rather than the extreme hypertrophy seen with Type IIa and IIb muscle fibres. This is the premise behind trainers recommending 6 reps for pure strength/muscle gain and why 10-15 reps are recommended to "tone" a muscle.
Finally, there are four different actions a muscle can perform; isometric, eccentric, concentric, and isotonic. An example of an isometric contraction would be pushing against a wall. Lifting a dumbbell during a bicep curl is considered the concentric portion while lowering of the weight is called the eccentric portion of the exercise. There are also called the positive and negative portions respectively. And finally, isotonic contractions are those that involve full body actions such as skating or running.

Essential oils, roots and herbs can be used in a variety of ways to promote healthy living and stress management tip. They are used to create natural remedies for treating ailments common to both people and animals, to add flavor to food, to make perfumes and to create environmentally friendly cleaning products.
You do not have to own a garden to tap into the benefits of plants, roots and herbs. A few herb pots located by a sunny window are enough to get you started. Then, all you need are some essential oils and you are ready to go.
For therapeutic purposes, only the purest oils will do. It is possible to be fooled into thinking that you are purchasing a pure oil. Often, a lesser quality blend of several oils is used to mimic the properties of the pure oil. Blended oils are acceptable for fragrance purposes such as for perfuming a room, but pure oils are a "must" for medicinal purposes.
A reasonable guide to the purity of an essential oil is its price. Pure essential oils are generally more expensive. Common oils such as lavender and geranium are much cheaper than frankincense and carnation oil. It is advisable to become familiar with essential oil prices and then rely on this knowledge when purchasing oils from unfamiliar sources. Keep in-mind that you will generally get what you pay for. A price list from a reputable dealer is a valuable resource when purchasing essentials oils.
Usually, pure essential oils cannot be applied directly to the skin and must be mixed in a base oil to reduce their strength. Base oils such as almond oil or wheatgerm oil are commonly used for this purpose. Base oils are generally derived from seeds, nuts or vegetables and allow you to create essential oil remedies that can be massaged into the skin.
So, what do you need to get started with essential oils and natural remedies?
Without a doubt, Lavender is one of the most useful and desirable oils. Not only does it work wonders on cuts, bruises and burns, it also aids sleep and helps with relaxation.
The Tea Tree and Eucalyptus oils are useful for treating a variety of respiratory ailments. These are excellent for the treatment of colds and coughs. They can be massaged into the chest or burned in an oil burner to help clear the airways and prevent congestion. Tea Tree oil is a natural antiseptic and can be dabbed on cuts, bites and stings. It is often used to treat spots and pimples and when diluted with water, acts as a mouth gargle (keep in-mind it should never be swallowed).
Another basic antiseptic is Geranium oil. With its distinctive perfume and pain relieving properties, it is a necessary inclusion when starting out.
Peppermint oil should also be purchased as it treats digestive complaints and may be used in preparations for freshening breath.
For fragrant perfumes and establishing ambience in a room, buy some Patchouli and Ylang-ylang oils. Often combined in scented candles and air fresheners, a few drops of each in an oil burner creates a wonderfully perfumed home. Orange oil mixed with Cinnamon oil is a lovely winter alternative that evokes seasonal, holiday smells. Besides their perfume qualities, all four of these oils have other properties. Patchouli treats eczema and dandruff. Ylang-ylang is reputed to relieve stress, palpitations and high blood pressure. Orange is used in natural remedies for depression and nervous tension and Cinnamon is excellent for warts and viral infections.
The herbs, Thyme and Rosemary can be grown in pots and used when needed. To create essential oils from herbs, stew some large amounts in pure water, collect the steam and cool it. The oil will rise to the top of the drained water and can be collected with an eyedropper. Alternatively, a "flower still" can be purchased to make the job easier. Thyme and Rosemary are both antiseptics and can be used in skin care preparations. They are also delicious when used in cooking.
Lemon oil and fresh lemons will purify water and, when mixed with honey, are effective remedies for colds and flu. Lemon and white vinegar are highly efficient cleaning agents that can be used for domestic cleaning tasks without damaging the environment. Use white vinegar as a natural disinfectant or mix it with water to clean windows and wooden floors. It is also handy to keep a bottle of white vinegar in your car if you swim in the ocean. It will bring instant relief from jellyfish stings.
Citronella oil is perfect in summer to keep the insects at bay. Another natural repellent is Garlic. Fleas will not bite a dog that has been eating garlic, so a few garlic capsules in the dog food are a cheap solution to your pet's flea problem. A soft collar soaked in Citronella will also do the job.
Garlic also helps to promote a healthy immune system when the weather turns cold and viruses begin to circulate. In fact, most of the oils and herbs listed above are effective in helping to prevent many common winter illnesses.
Whether you are looking for remedies or nature friendly products to use around the house, the oils and herbs suggested above should help get you started. You will be ready to make some healthy changes in your way of life!
