Multiple sclerosis (MS) is a neurological disease characterized by a variety of potentially debilitating symptoms. The manner in which the disease affects each individual is unique; however, many individuals with MS have a normal life expectancy and remain ambulatory throughout their lives. Very little research has focused on understanding how ...

Recent social policies have focused on reentering persons with mental retardation (MR) into the work force and the mainstream of society. However, as individuals with MR age, their rate of institutionalization greatly outweighs that of the general population as well as children with MR. Health care organizations have expressed serious ...

Two studies examined the effects of physical activity/exercise on physical self-perceptions, self-efficacy, body satisfaction, fitness and relationships among these variables. In study 1, 34 female undergraduates participated in a 10-week exercise/activity program. Participants were selected from existing classes forming a weight training, aerobic exercise and activity control group. Results revealed ...

BACKGROUND: Research on smoking and physical activity provides strong evidence of smoking's negative impact and physical activity's positive impact on long-term health. However, evidence regarding the association between smoking and exercise activity and the independent effects of these factors on fitness is lacking. METHODS: The associations among exercise activity, smoking ...

There is unanimous agreement that regular exercise is essential for optimal function of the human body. It is evident that extrinsic factors, such as diet and exercise habits, are reflected in the morbidity and mortality statistics, especially in aging. Aging is obligatorily associated with reduced maximal aerobic power and reduced ...

There is international agreement that those in the community who are habitually active, either in work or in leisure, have a better coronary risk profile and a lower death rate from coronary heart disease (CHD). This agreement is usually translated into recommendations encouraging the population to perform regular aerobic exercise ...

At a cellular level, the major phenomenon in Dupuytren's contracture is an increase in proliferating fibroblasts, rather than an alteration in the type of fibroblasts. The collagen and glycosaminoglycan changes observed in the tissues of Dupuytren's contracture are likely to be secondary to changes in fibroblast density. Oxygen free radicals ...

A cohort of 6165 municipal workers 44 to 58 years of age was followed during 1981-1985. The most impairing work loads were poor work postures and poor physical climate, whereas good possibilities for development at work prevented work disability. Aging particularly increased the incidence of work disability, whereas physical exercise ...

The present investigation was designed to evaluate whether dynamic physical exercise is able to modify stapedius reflex (SR) activity and, as a consequence, to influence the amount of temporary threshold shift (TTS). Experimental subjects were 10 normal-hearing male volunteers, aged 27-34 years (mean 30.8). SR parameters in the time-domain were ...

Staying physically fit while injured can improve the patient's outlook, both physiologically and psychologically, and help him or her return to regular activities completely, safely, and with decreased risk of re-injury. Although treating and protecting the injured area is of primary concern, it is important to then look beyond the ...

Patients who have clinically recovered from Guillain-Barré syndrome (GBS) may exhibit a deficit during strenuous exercises that require maximal effort and muscular endurance. The Army Physical Fitness Test (APFT) is a quantitative tool that challenges neuromuscular endurance and unmasks a subclinical deficit in soldiers who have apparently recovered from GBS. ...

In general, depressed patients are physically sedentary. They have reduced physical work capacity but normal pulmonary function compared with the general population. This indicates that the reduced fitness level is caused by physical inactivity and is a strong argument for integrating physical fitness training into comprehensive treatment programmes for depression. ...

The inhibition by opiates and the sudden normalization by opioid antagonists of the brain L-asparaginase activity (BAA) have previously been reported to be the main factors in the development of physical dependence and the manifestation of precipitated abstinence syndrome, respectively. As a result, L-asparaginase inhibitors D-aspartic acid and prolyl-leucyl-glycinamide (PLG) ...
Czajkowski S M - - 1990

It has been reported that physical exercise may enhance cytochrome P-450 dependent drug metabolism in vivo. In this study we report that the specific activity of aryl hydrocarbon hydroxylase (AHH) in human peripheral lymphocytes (HPL) is enhanced approximately two fold following acute physical exercise. This enhancement of AHH activity in ...

Experimental studies of hypokinetic physiology are generally based on the assumption that diminished muscular activity (progressive reduction of number of steps per day) is hostile to animal and human organisms, since the entire animal kingdom has been formed in a high motor activity environment, which left its imprint on the ...
Micheo W F - - 1989
With improved long-term survival of the disabled patient the incidence of cardiovascular disease is increasing in this population. One important factor is the low level of physical activity of disabled individuals. Disabled patients respond similarly to their able-bodied counterparts to training programs of a frequency, intensity, and duration which permit ...

This essay suggests that contemporary fitness practices share aesthetic and ideological commitments with other activities that have been classified as postmodern. The aesthetic similarities are evident in the use of pastiche and simulation by manufacturers of exercise machines and videotapes. In terms of ideology, the pursuit of fitness is promoted ...

Regular physical activity in the elderly delays decline in physical abilities, improves quality of life, and enhances functional capacity. As medical costs rise, preventive measures such as exercise are attaining great importance. Physicians should encourage their patients to participate in routine exercise and assist them in selecting an appropriate program. ...
