Exercise And Harm

Thursday, June 26th, 2008

Anytime you exercise, your brain releases chemicals known as endorphins that produce a feeling of euphoria, which is known as “runner’s high”. It is also very easy to become chemically addicted to this feeling.

Without this rush, you’ll feel irritable and out of it until you exercise again. Therefore, you’ll go on exercising and not listen to what your body is actually telling you - which is to ’stop’.

The main reason addicts will continue to push themselves lies in what will happen when they don’t work out. Normally when they are unable to exercise, they will display signs of depression, anxiety, confusion and be less happy with themselves.

Aches and pains.

Over exercising doesn’t only affect the mind, but the body as well. Exercise will initially do what it is intended to do - give you a fit body, but once you cross the line however, it can be drastic. Muscle damage, osteoarthritis and heart problems will all be waiting in the wings if you continue to overdo it. The body has limits and if you push beyond that limit, you’ll do nothing but harm to yourself.

Obsessive exercise tends to happen among those who are new to exercise. Therefore, if you are keen to reap the benefits of getting fit, you’ll tend to overstep the limits.

The initial signs of over exercise are exhaustion, which can lead to a build up of fatigue. Keep in mind, it isn’t only the muscles that are at risk, but the bones as well. Many people who exercise, push themselves to the point of injuries such as shin splints or even stress fractures, then refuse to rest, which causes greater and sometimes even permanent damage.

Even a brisk walk in the morning doesn’t come without risk, as walking too much can lead to osteoarthritis. When you walk, you are working against gravity. Even though you are exercising your muscles, you are also harming your knee joints as well.

Many people who walk up to an hour or more everyday end with complaints of aches in the knees. The fact is, jogging also harms the knees and too many sit ups can also hurt as well. As with any type of exercise, moderation is the key.

You should always start off gradually and combine several different types of workouts, which is one that that obsessive exercisers forget to do. One of the biggest complication factors of people who get addicted to exercise is that they will tend to perform the same workout each and every day, which further increases the risk of permanent damage.

Think right.

You should never work out to the point where you feel completely exhausted once you have finished. Your limit with exercise should be 45 minutes to an hour, four or five days a week. When you are finished, your workout should leave you feeling fresh and energetic. Every week you should make it a point to take a day off to let your body relax and rejuvenate.

If you take things one day at a time and don’t over do it, you’ll be well on your way to a healthy body. Exercising can be a lot of fun and a way to relax, if you don’t rush it. Start off slow and gradually work your way up. Before you know it, you’ll know how to prevent injuries before they happen and you’ll know exactly what you need to do to remain healthy.

The results are all based on the same foundation of sound nutrition, good exercise and realistic expectations. Realistic expectations will get you a long way to achieving your goals, so do take the time to consider what you can do and what you can maintain over the long term.

Once again, using good quality supplements can help considerably by maintaining balanced nutrition and reducing hunger that comes about from your body telling you that something is missing in your nutrition.

The first step is always the hardest and the further you go, the easier the journey becomes provided of course, that you have chosen the right path to follow!

Why Muscles Get Sore

Tuesday, June 24th, 2008

As people age, they begin to complain more of pains in their muscles and joints. They seem to stiffen up with age and such commonplace activities as bending over for the morning paper can make them wince.

Such pain can grip so fiercely that they are sure it begins deep in their bones. But the real cause of stiffness and soreness lies not in the joints or bones, according to research at the John Hopkins Medical School, but in the muscles and connective tissues that move the joints.

The frictional resistance generated by the two rubbing surfaces of bones in the joints is negligible, even in joints damaged by arthritis. Flexibility is the medical term used to describe the range of a joint’s motion from full movement in one direction to full movement in the other. The greater the range of movement, the more flexible the joint.

If you bend forward at the hips and touch your toes with your fingertips, you have good flexibility, or range of motion of the hip joints. But can you bend over easily with a minimal expenditure of energy and force? The exertion required to flex a joint is just as important as its range of possible motion.

Different factors limit the flexibility and ease of movement in different joints and muscles. In the elbow and knee, the bony structure itself sets a definite limit. In other joints, such as the ankle, hip and back, the soft tissue-muscle and connective tissue limit the motion range.

The problem of inflexible joints and muscles is  similar to the difficulty of opening and closing a gate because of a rarely used and rusty hinge that has become balky.

Hence, if people do not regularly move their muscles and joints through their full ranges of motion, they lose some of their potential. That is why when these people  try to move a joint after a long period of inactivity, they feel pain and that discourages further use. What happens next is that the muscles become shortened with prolonged disuse and produces spasms and cramps that can be irritating and extremely painful. The immobilization of muscles, as researchers have demonstrated with laboratory animals, brings about biochemical changes in the tissue.

However, other factors trigger sore muscles. Here are some of them:

1. Too much exercise.

Have you always believed in the saying. “No pain, no gain?” If you do, then, it is not so surprising if you have already experienced sore muscles. The problem with most people is that they exercise too much, thinking that it is the fastest and the surest way to lose weight. Until they ache, they tend to ignore their muscles and connective tissue, even though they are what quite literally holds the body together.

2. Aging and inactivity.

Connective tissue binds muscle to bone by tendons, binds bone to bone by ligaments, and covers and unites muscles with sheaths called fasciae. With age, the tendons, ligaments and fasciae become less extensible. The tendons, with their densely packed fibers, are the most difficult to stretch. The easiest are the fasciae. But if they are not stretched to improve joint mobility, the fasciae shorten, placing undue pressure on the nerve pathways in the muscle fasciae. Many aches and pains are the result of nerve impulses traveling along these pressured pathways.

3. Immobility.

Sore muscles or muscle pain can be excruciating, owing to the body’s reaction to a cramp or ache. In this reaction, called the splinting reflex, the body automatically immobilizes a sore muscle by making it contract. Thus,  a sore muscle can set off a vicious pain cycle. First, an unused muscle becomes sore from exercise or being held in an unusual position. The body then responds with the splinting reflex, shortening the connective tissue around the muscle. This causes more pain, and eventually the whole area is aching. One of the most common sites for this problem in the lower back.

4. Spasm theory.

In the physiology laboratory at the University of Southern California, some people have set out to learn more about this cycle of pain.

Using some device, they measured electrical activity in the muscles. The researchers knew that normal, well-relaxed muscles produce no electrical activity, whereas, muscles that are not fully relaxed show considerable activity.

In one experiment, the researchers measured these electrical signals in the muscles of persons with athletic injuries, first with the muscle immobilized, and then, after the muscle had been stretched.

In almost every case, exercises that stretched or lengthened the muscle diminished electrical activity and relieved pain, either totally or partially. These experiments led to the “spasm theory,” an explanation of the development and persistence of muscle pain in the absence of any obvious cause, such as traumatic injury.

According to this theory, a muscle that is overworked or used in a strange position, becomes fatigued and as a result, sore muscles.

Hence, it is extremely important to know the limitations and capacity of the muscles in order to avoid sore muscles. This goes to show that there is no truth in the saying, “No pain, no gain.” What matters most is  how people stay fit by exercising regularly at a normal range of motion.
