{"title":"Obesity and physical activity.","authors":"B Hamborg","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Obesity has a close connection with energy balance. Available methods of measurement are, however, too coarse to measure minor daily oscillations that over the months or years can indicate a rise of several kilograms. Basal metabolism is an important part of total energy consumption. This varies with age, sex and body composition. Several investigations appear to show that physical activity can raise basal metabolism. With the help of direct and indirect calorimetry it has been possible to calculate energy consumption above the basal figure. However, in calculating the energy gain through exercise it is necessary to subtract the energy consumption that would otherwise have taken place. Theories have been put forward that the different types of overweight (hyperplastic and hypertrophic) show different gains from physical training as regards weight reduction. However, classification of overweight persons in groups is somewhat uncertain. Physical activity has been found to restore to normal the metabolic changes which are often associated with obesity. There are also cases in which no loss of weight occurs. Physical training has a favourable effect in regulating appetite. Dropout from training programmes is considerable in the overweight. Associated locomotor symptoms may also complicate training. Even though there is little evidence in the literature to show that the majority of overweight persons lose significant amounts of weight without accompanying dietic restrictions, physical training is undoubtedly of great value in these groups.</p>","PeriodicalId":76526,"journal":{"name":"Scandinavian journal of social medicine.

The disease (arteriosclerosis obliterans) is characterized by a reduction in the blood flow through muscles and in oxygen uptake, together with increased lactate excretion during work, usually in spite of a developed arterial collateral system. An increased ability to extract oxygen from the blood while the affected muscle metabolism is modified in the direction of greater aerobic capacity can partially compensate for the reduction in blood perfusion. Physical activity which involves large muscle groups and is continued beyond the boundary of pain leads to an increase in both claudication distance (the distance until pain appears during normal walking on the flat) and the walking distance (maximal distance the patient can walk). Since the blood flow is unchanged or reduced, the effect seems not to be due to improved vascular capacity. It has however been shown that training gives rise to further increase both in the ability to extract oxygen from the blood and in the metabolic activity of muscle tissue. It is concluded that, if indications for surgical treatment are not present, training by walking with regular controls constitutes good treatment favourable to health economics and able to improve the patient's quality of life.</p>","PeriodicalId":76526,"journal":{"name":"Scandinavian journal of social medicine.
