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.

Digital Infrared Photography Pictures Made Easy

Digital infrared photography is a fairly basic photographic technique that yields amazing images. There is a spectrum of light that can not be seen with the human eye, but it can be seen and captured through the lens of your digital camera.

Images captured with this technique have a surreal dreamy look. A picture of a green leafy tree against a bright blue sky taken with digital infrared photography becomes a picture of a brilliant white tree against a dark foreboding backdrop of sky.

This happens because visible light is ignored and only infrared light (light from the spectrum we can not see with the naked eye) is captured. The resulting compositions are stunning. However, the technique is not difficult.

Digital Infrared Photography Equipment

Infrared pictures can be really unique. Here is a resource to learn more about the technique and see samples of what can be done with inferred photography.
A digital photography course is a great way to learn this technique. There are even free digital photo classes offered online [http://www.mydigitalphotoclasses.com/digital-photo-classes.html].

Modern digital cameras differ in their ability to capture infrared light. To test your camera's infrared capabilities, point your television remote control at your digital cameras lens from 6 inches away and press a button on the remote. If you see a light in your camera's LCD coming from your remote, you're in luck. Your camera is capable of digital infrared photography. If you saw no light being emitted from the remote, your camera probably has an internal infrared filter installed by the manufacturer to preserve the camera's ability to focus on images in the normal light spectrum.

Now that you've tested your camera, you need only two additional pieces of equipment: a filter and a tripod. The purpose of the filter is to "filter" out visible light and only let infrared light through. Filters are fairly inexpensive (approximately $ 20). The Hoya R72 filter is one of the more popular filters and can be obtained from your local camera store. If your camera has a thread adapter (most digital cameras do not), you'll also need to purchase an adapter. If your camera does not have a thread adapter, you'll have to get creative to attach the filter. With gelatin filters, it's as simple as cutting the filter to size and taping it to your lens. Your local photography store should be able to help here, too. While you're at the camera store, pickup a tripod also. These are needed due to the increased aperture and reduced shutter speed required for infrared photography.

Shooting Techniques

Once you've got your camera outfitted with an infrared filter, you're ready to go out and shoot. Landscapes with green leafy foliage and a bright sky make the best subjects when starting out. Portraits of people in sunlight also make interesting compositions. Every camera is different so you'll want to experiment with various settings and their effect. Some cameras are capable of taking good digital infrared photography in "automatic" mode, so try that first. However, if "automatic" mode does not yield good results, the following is a list of manual settings to use as a starting point:

  • Flash Off
  • Black & White Mode On
  • Film Speed: ISO 400 (or the highest available)
  • Shutter Speed: 1/15 of a second (slower is better)

Digital infrared photography opens up a whole new world to photographers. With just a few relatively cheap pieces of equipment, you can create stunning compositions from the world of the invisible light spectrum. This article just scratches the surface of what you can do with digital infrared photography . There is so much more that can be done within this area of ​​photography and there is a whole array of other basic photography techniques that yield amazing results. The best way to learn how to take full advantage of your digital camera or expand your photographic skills is by taking a digital photo class. They are a lot of fun and with just a little instruction you can learn how to take amazing pictures.

Child Cognitive Development

In the present time, nobody thinks that the babies are not capable of understanding things. Scientists have explained with the aid of several examples of how babies are, for instance, very much capable of reacting or hearing to any sound.

You may be a bit surprised to know that the child cognitive development begins when s / he is in the womb. The brain begins to mature when a baby is in the stage of a fetus.

It is true that they can not master the arts, but it is a proven fact that the babies start connecting with the outer world at this pre-natal stage. It basically depends on the age of the baby. The child cognitive development is a matter of time. Do not expect from your baby that s / he can make all the movements or can use the language nicely at the primary age.

There are some certain features that the child doctors and psychologists can explain to you regarding how much can you expect at every certain age / stage of the baby.

When the baby is of 3 months, you can notice certain child cognitive development in your baby. In this primary stage, the infants try to cope up with the world as her / his senses have so developed. The baby gives responses to the facial expressions. S / he can distinguish between sounds.

The baby can differentiate among various tastes as well. It is not possible that s / he knows what is sweet and what is bitter at this early stage. Neverheless, s / he can realize that two tastes different from each other.

At the age of three to six months, the baby's perceptual abilities get to a higher level. The infants can recognize faces now. They can make themselves familiar with the common faces.

Another important child cognitive development is that the baby can now differentiate one person from another as well. The baby follows her / his newly grown senses to identify persons. S / he can identify someone to be quite close to her / him through the voice, touch, and look.

Between six to nine months, the baby usually stares at the hanging objects. They have a little idea of ​​the outer world and how it functions. The hanging objects are like something impossible to them and they stare at them for a long time.

At the age of twelve months, the child cognitive development reaches a certain limit when the baby can recognize herself / himself from others. S / he can imitate various gestures and actions of the elders. The baby can also respond to the simple directions that you give to her / him. In this slow but steady way, the baby slowly develops the faculties that will be with her / him for the rest of life.

Lubrication of Domestic Clocks

Domestic clocks are one of the most ignored watches in the entire household. We make sure that our wrist watches are well maintained with good servicing, battery changes and of course lots of lubricating. But domestic watches are practically ignored till the battery runs down. Even then, we just replace the battery without getting any servicing or lubricating done on it. That means that the watch continues to run without any care or oiling till they finally expire and die! But just like wristwatches, domestic watches need to be maintained well too with regular cleaning and lubrication and care. Clocks are larger than wristwatches so a little too much lubrication is OK here.

But still there are rules to be followed in lubrication and care of clocks like-

* Try to use just a single drop of oil in the watch works to make the watch remain on time. These are bigger watches so they don’t really require you to be precise but it’s a good idea if you are. Carriage clocks require a smaller amount while long clocks and grandfather clocks require much more.

* Try not to scrape the oil pots while oiling watches as it scrapes up unnecessary settled grit into the workings of the clock. This is especially true of incalite pots. Use only fresh oil and discard any which has more than five years on the packing date on the seal; protect the oil you are using by storing it at room temperature and away from direct light. An ideal temperature would be about 15 to 20 C or as stated by the manufacturer of the clock. There are several points on a domestic clock where you can oil them and the oil will them spread to all over the clock workings. Good places to apply lubrication are at oils sinks or pivot holes, escapement pallet faces, weight pulley bearings and points of contact between different parts of the mechanism.

* Make sure you do clean the mainspring and refit the watch springs after you have oiled the domestic wall clocks. You can also apply heavy grade mineral oil around the edges of the barrel cap. Capillary action will make sure that the oil spreads all over the mechanism.

* Do not lubricate or oil pinion leaves and gear teeth, as they will slip while revolving. Another place to be careful of is the ratchet and the great wheel arbor in the main clock facings.

* The frequency of oiling depends on how frequently you use the clock and the location it is based in. Synthetic oils are very stable and do not deteriorate but non-synthetic oils do. The residue leaves a gummy deposit in the watch that can destroy a good watch.

* Contamination with dust will however really cause a tremendous amount of wear on the clock and that can damage the mechanism. Reapplication of oils is fine after the old one has been wiped off.

But do make sure that you do service the watch at least every two years to maintain optimum working conditions.
