The Most Important Components of Physical Fitness

There are components of physical fitness which insurance companies and trainers take into account as they are significant to the overall evaluation of health. Basically it is similar to a fine-tuning a racing engine, you would never add diesel to an engine that requires high octane.

When physical trainers measure the fitness of a person they use some components of physical fitness to test against a set standard and to develop goals for further improvement. By incorporating these components of physical fitness you can not only improve your health but also lose weight.

The first of these is muscular strength. This measures the ability of the muscle to exert a maximal force through a range of motion or to a given point. This is measured for a short period of time and usually incorporates the use of weights for evaluation.

As muscular strength varies through the body, you might for instance you have
high muscular strength in your arms while having weaker legs, this component is related to the amount and type of exercise that your body undergoes. Weight training or strength training is the only method to improve strength. One principle of increased muscle mass is that that a larger amount of muscle consumes a greater number of calories, even at rest. By increasing mass you effectively increase the amount of calories needed for your body at rest and will reduce your body fat ratio. Another benefit to strength training is that it will help to maintain your bone structure and decrease your risk of osteoporosis.

The second component is muscular endurance. This reflects to your muscles ability to work through a range of motion over a specific amount of time. This can be measured by the ability to hold a weight for a specific amount of time – say 20 pounds over-head for 5 minutes. Many times this component is measured through push-ups as these are exercises that exert a specific amount of pressure over time. This measures the upper body muscular endurance.

Muscular endurance is often confused with muscular strength because they are related. However they offer different benefits, while using muscular endurance an athlete is able to shovel snow for an hour lifting and moving a sub-maximum amount of snow over a specified amount of time. Muscular strength would have been the ability of the arms and shoulders to lift the maximum amount a couple of times.

The trainer will test muscular endurance while he will also be testing cardiovascular endurance because these two components are closely related. Cardiovascular endurance will reflect how well your heart and lungs work together to supply oxygen to your body, this is also called aerobic fitness. Trainers may use long runs or swims to test cardiac endurance and test muscular endurance at the same time. This is the cornerstone to complete health and fitness. Without cardiovascular endurance you can not improve the rest of your fitness.

Another component is flexibility, this is the ability of a joint to move through its full range of motion and the elasticity of the muscles. Some refer to this as how limber or supple you are, this is a major component of physical fitness and one that is often over looked. Not everyone needs to be as limber as a gymnast but we all need a degree of flexibility to deal with the demands placed on us during our daily lives.

Stretching is associated with flexibility in order to maintain or increase the ability of a joint to stretch further. Maintaining your flexibility is important for protection of your joints and allowing you to strengthen further to protect your back and reduce the pain of arthritis.

The final component of physical fitness is body composition. This is the ratio of lean body mass to fat body mass. This proportion does not refer to your weight in pounds or to your figure but to a measurement against a standard. Women and men have different body composition ratios. Women carry a higher percentage of fat to maintain a developing baby. This does not mean that women are fatter – but that their fat distribution is different.

Your body composition is really more a consequence of your overall fitness. If you have a high body fat mass ratio you are more at risk for coronary heart disease, diabetes, joint and back pain, arthritis, stroke and tendon-muscle accidents.

These components of physical fitness are foundation to physical fitness and the ability of the human body to withstand external forces and internal stress while maintaining health and wellness.

Vacations Are Fun, The Traveling With Kids Is Not!

Vacations are a time to remember. Years after a holiday we remember the merirement that we had enjoyed during a particular vacation. Although the holiday is memorable, traveling to the selected destination is probably the most tiresome part of the package. The process becomes even more tedious if you are traveling with kids.

Their low attention span and impatience is the primary reason why they get over excited wherever the destination is grandma's place or Hawaii. Not an hour passages by when parents hear the endless chime of 'when do we get there?'

Making these long car rides or a trip in the airplane is not as difficult as it may seem to a harassed parent. A wee bit of planning in advance to keep your young tykes in control will see you a long way. A variety of games will keep them engaged and divert their minds away from the long wearisome travel.

If you have not come across some games which are apt for travel time then here are a few. For bumpy car rides where children can not indulge in board games try 'spot the letter of the alphabet'. The game involves reading road signs or billboards and spotting the letters of the alphabet in the sequence. So if you come across 'Abacus building systems', the letters A, B, C, D and E are found.

In the next billboard they should look for F. This game is suitable to be played alone or with a sibling. Create a competition between two children by allotting one side of the road to each and see who reaches the end of the alphabet first.

Another extremely simple and interesting game which can be played while traveling on the freeway is 'license plates'. The objective of the game is to identify vehicles from different states using their license plates. Keep them busy by telling them to keep going till they see plates from all 50 states.

The tussle of managing a child on the airplane can be more embarrassing than a car drive. With a hollering baby you are sure to get dirty glances from the scores of passengers traveling on board. Coping with toddlers on a plane is easier since the journey is much smoother than a car ride and drop down trays can be used to play board games

If traveling with an infant, then make sure that your little one is comfortable to ensure a peaceful flight. Try and time your babies sleep to coincide with the flight timings. Feed your baby during take off and landing to reduce discomfort in the ears.

Planning activities specifically suited for travel will help you recall the vacation with fondness and visions of the harrowing time you had not cross your eyes every time you look back.

Diamond Earrings and Other Fine Jewelry

Diamond rings are the most common form of diamond jewelry, but diamond earrings, bracelets and necklaces are also quite popular. In fact, diamond jewelry has been around since the days of the Roman Empire, although it took almost 1500 years before diamond jewelers had figured out how to cut diamonds into attractive shapes that displayed their "fire," or shine and brilliance. Diamond earrings are but one way that people adorn themselves with this mystical, precious gem.

A Fascinating History

Chances are that the first diamond jewelry was from India. The tremendous geologic forces required to form diamonds exists mainly in regions of the world where one tectonic plate slams into another; the Himalayas, where the Indian subcontinent plows into Central Asia, is one such place. Loose diamonds from deep underneath these mountains have been known to appear in the rivers that flow south and westward from the Himalayas: the Ganges, the Brahmaputra and the Irriwaddy have all been sources of these rough, octagonal crystals.

Before diamond jewelers had learned the art of precision cutting, diamond earrings were not particularly beautiful; rough and dull-looking, they were nonetheless prized for their hardness.

One early example of diamond jewelry in the West was actually a crown made for a Hungarian princess well over 1000 years ago. One of the first diamond wedding ring was the one given to Marie of Burgundy on the occasion of her wedding to Archduke Maximilian I of Austria in 1477. It was not until over fifty years later however during the reign of Henry VIII of England that diamond cutting had reached a level that was suitable for jewelry such as diamond earrings.

Dull and Lifeless

If you had been buying diamonds back then, you'd have been disappointed; those early cuts did not show the kind of brilliance that we see in fine diamond jewelry today. It was not until the 1800s that art of diamond cutting had reached a level of refinement that allowed the gem's real beauty to shine through the way it does in contemporary diamond jewelry.

Fiery and Brilliant

Today, there are many different cuts to choose from when buying diamonds . Round cuts and square cuts both have characteristics in their favor, but a reliably new cut, called the "princess," has been gaining in popularity over the past thirty years or so. This particular cut combines the best features of round and square cuts, and causes the least wastage of all cutting methods – so the gem retains much more of its original weight. All three cuts however will make for highly attractive and valuable diamond earrings .
