Jogging and aerobic dance exercises are excellent for cardiovascular conditioning, weight control, and improvement of a variety of conditions; however, reasonable caution should be observed.
Jogging has been used successfully in rehabilitating cardiac patients and those with pulmonary emphysema; in weight reduction of diabetics; in relaxing insomniacs, the emotionally disturbed, and migraine patients; and in reducing the discomfort accompanying arthritis in the legs and back. Like many other exercises, jogging should not be done without a physician’s approval for those with arthritis, osteoporosis, and heart and circulatory diseases. It is not harmful to women, although some women may need to wear a special bra as a comfort measure. Jogging can cause shin splints, blisters, and foot, ankle, knee, and hip problems. Using the proper footwear and learning how to jog correctly will minimize these hazards. If you have poor leg or foot alignment, you would be wise to jog only three or four days per week because studies show that the risk of injury is greatest for those who jog every day. The same fitness levels will result with less risk of injury. (more…)

Exercise adherence means regular lifetime exercise. Positive addiction is another term commonly used to describe this healthy life-style. The implication is thatexercise is addicting, but unlike addictions such as drugs and smoking, the consequences of the addiction are positive. Experts have not established that exercise can be addicting, though it is generally agreed that some people develop very strong exercise habits (exceptional adherence) even to the point of exercise neurosis. Habitual exercisers regularly indicate that they have positive feelings, even feelings of euphoria, when they do regular, sustained exercise. (more…)

There are many fallacies, myths, and superstitions associated with strength training.
Some common misconceptions about strength training have been refuted.
It is not true that you will become muscle-bound and lose flexibility just because you do strength training. This could happen only if you train improperly. It has been found, however, that power lifters are less flexible than other weight lifters.
It is not true that women will become masculine looking if they develop strength. Contrary to popular belief, most women will not be able to develop as large and bulky muscles as men nor will their muscles be as well defined. On a heavy resistance training program, women and men make about the same percentage change in strength and hypertrophy. The greater percentage of fat in most women prevents the muscle definition possible in men and camouflages the increase in bulk. (Until CAT scans were used in research studies, it was not evident that women achieved hypertrophy at the same rate as men.) (more…)

People have always searched for the fountain of youth and the “easy,” “quick,” and “miraculous” route to health and happiness. This search has included the area of physical fitness, especially exercise and weight loss. Because of the popularity of these two subjects, the mass media have made it possible to convey as much misinformation as information. All people should seek the truth to protect their health as well as their pocketbooks. This concept discusses some myths and separates fact from fancy.

There are many different positive life-styles that can reduce the risk of disease.
Many of the factors that contribute to optimal health and quality of life are also considered risk factors. Changing these risk factors can dramatically reduce the risk of hypokinetic diseases such as heart disease, obesity, back pain, and cancer, as well as other diseases such as infections and sexually-transmitted diseases. Lack of exercise, poor nutrition, smoking, abuse of alcohol and other drugs, inability to cope with stress, and poor personal hygiene are all risk factors associated with various diseases.
Not all risk factors can be altered by life-style changes. (more…)

It is not necessary to join a club, spa, or salon to develop fitness, but if you are considering joining such an establishment, make your choice with care.
The consumer should observe these precautions before becoming a member of a club, spa, or salon.
- Do not expect “miraculous” results as advertised.
- Be prepared to haggle over price and to resist a very hard sell for a long-term contract.
- Choose a no-contract, pay-as-you-go establishment if possible. Otherwise, choose the shortest term contract available. (more…)

Passive exercise is not effective in weight reduction, spot reduction, increasing strength, or increasing endurance.
- 1. Rolling machines—These ineffective wooden or metal rollers, operated by an electric motor, roll up and down the body part to which they are applied. They do not remove, break up, or redistribute fat.
- Vibrating belts—These wide canvas or leather beltsmay be designed for the chin, hips, thighs, or abdomen. Driven by an electric motor, they jerk back and forth, causing loose tissue of the body part to shake. They do not have any beneficial effect on fitness, fat, or on the figure, and they are potentially harmful if used on the abdomen (especially if used by women during pregnancy, menstruation, or while an IUD is in place). They might also aggravate a back problem. (more…)

1. Increased physical fitness
Community surveys have shown that the general level of fitness in this country is ‘deplorably low’ and patients who suffer coronary problems have even lower levels. The improvements achieved by physical training as described above are of obvious benefit to the daily activities of cardiac patients. The energy costs of a wide variety of activities both at work and leisure have been estimated,”” and can theoretically allow prediction of the ability of cardiac patients to perform such tasks. In the United Kingdom the ability to regain a licence to drive a large goods or passenger carrying vehicle depends on the completion of 9 minutes of the Bruce protocol treadmill test, a feat that may only be possible after exercise training.
One group that may have most to gain is patients with cardiac failure.

As obligatory urine losses persist even in the dehydrated state, it is clear that any drink consumed after exercise-induced or thermal sweating must be consumed in a volume greater than the volume of sweat that has been lost. To investigate the influence of drink volume on rehydration effectiveness, 12 male volunteers performed intermittent exercise in the heat to induce a level of dehydration equivalent to a mean of 2.06% of their initial body mass.

A study was undertaken to examine the effect of the sodium content of drinks on the rehydration process after exercise-induced dehydration equivalent to l.9% of body mass of six fasted but euhydrated men.’ After dehydration they consumed drinks with sodium concentrations of l, 25, 50, and 102 mmol/l over a 60 minute period beginning 40 minutes after the end of exercise; the volume consumed was l.5 times their mass loss by dehydration which amounted to about 2 litres in all trials.
The entire volume of urine produced over the 6 hours after the end of the drinking period was collected and measured (no other food or drink was consumed after the rehydration period). The volume of urine produced was influenced by the quantity of sodium consumed, such that it was greatest when the 1 mmol/l drink was consumed and least when the 102 mmol/l drink was consumed (fig 14.l). The sweat secreted during the exercise was collected and the sodium content measured; the mean (SD) concentration was 49.2 (18.5) mmol/1. Calculations of whole body sodium balance can be made, taking the pre-exercise values as the zero point (fig 14.2); the results clearly show that there is a strong relation between the sodium content of the ingested fluid and its ability to restore water balance.

1. Contraindications
There are some absolute contraindications, such as unstable angina, worsening heart failure, critical valve stenosis (mainly aortic), malignant arrhythmias, very recent infarction, and any acute intercurrent medical condition such as venous thrombosis or febrile illness: Relative contraindications include severe angina, severe heart failure and non-critical valve lesions, and potentially dangerous arrhythmias. All of the latter may be treated but need much closer supervision than patients with fewer complications: Risk stratification of patients at the onset of an exercise programme takes all these factors and more into account.

Several measures have been suggested to reduce the negative effects of circadian rhythm desynchronisation, although treatment of shift workers, competitive athletes, and simple international travellers is quite different. The measures include preadaptation, meal timing and composition, phototherapy, and chronobiotic drugs.
1. Preadaptation
Theoretically, the negative effects of jet lag can be reduced by changing bedtime for several days before a transcontinental journey, remembering that sleep changes should correspond to the direction of travel (eastward or westward). Adaptation should be disturbed by behaviour that anchors the circadian rhythms to the previous phase for example, taking prolonged naps at the new destination. To lock the circadian rhythms to home time, at least 4 hours sleep taken within the window of normal sleep in the home time zone are needed. However, in practice, preadaptation is superfluous when people are travelling west, arriving late, and only a few hours phase advance can be recommended before travelling east. Moreover, because of the difficulty of manipulating other synchronising factors (light, social constraints), preadjusting the sleep-wake cycles is largely ineffective. (more…)

In the United Kingdom most cardiac rehabilitation programmes are run by nurses or physiotherapists with help from a multidisciplinary team, which in some cases includes sports scientists or other exercise specialists.’ The programme is divided into four phases.13 Phase 1 covers the time in hospital after acute myocardial infarction, and exercise is limited to gradual mobilisation including stair climbing to prepare the patient for discharge. Phase 2 includes the first few weeks at home when the main exercise, usually unsupervised, is a progressive walking programme. Ideally the patient is sent out with clear written guidance, and supplementary support can be given by telephone contact with a primary care team. Phase 3 is the supervised exercise programme which is the centrepiece of a package of care which includes education, dietary instruction, risk factor monitoring, stress management, and relaxation training. Phase 4 is the long term exercise to which it is hoped that most patients will adhere. In practice more than 50% will drop out of regular vigorous exercise once the supervised programme is over. A necessary prerequisite to phase 3 is the exercise test. (more…)
