Obesity is blamed for over 2.8 million annual deaths all over the world with increasing prevalence ofrelated comorbidities, including metabolic (e.g. diabetes mellitus, hyperlipidemia, hypertension) andnon-metabolic disorders (e.g. cancer, stroke, depression, polycystic ovary syndrome, fat liver disease,glomerulopathy, bone fragility etc.) The aim of the study was to describe the causes and remedies ofobesity. There are two primary causes for the increase in obesity: lack of an active lifestyle and poornutrition. Fortunately, inactivity and poor nutrition are causes that can be altered throughintervention. The PA based on walking in duration of 5 months were used in subjects withBMI>30kg.m-1. The PA was controlled in 192 middle age women, 67 men of the same age, and 58women seniors with help the pedometer Omron HJ720IT and energy content was controlled by Caltrac,and by relationship between speed of walking and VO2. VO2peak was improved from 13.2±2.1% inwomen to 15.1±2.4% in men, and by 13.0±2.7% in senior women. Similarly was altered the motorperformance – maximal speed of walking on the treadmill about 11.3±2.6% in women and16.2±3.1% inmen, and by 10.8±2.6% in senior women. %BF was decreased by 7.2±1.9% in women and by 6.5±2.0%in men, and by 6.7±2.4% in senior women. Together with these variables were significantly improvedthe predispositions for physical and workload evaluated by ECM/BCM coefficient (6.8±2.5% in women,7.9±3.1% in men, and 8.5±3.0% in senior women). We may concluded that walking with the meanenergy content of 1500kcal.week-1 (9430 ± 840steps.day-1)in females and men of middle age, and energycontent about 1000 kcal.week-1 (6930 ± 610steps.day-1) in senior women is able to significantly reducethe overweight and/or obesity and an improve actual fitness state in subjects without regular movementregime. Therefore, the chance of success in reducing the effects of hypokinesia have only those PA, whichare cheap, safe, well manageable and easily available for sale in the times and conditions, complyingwith the intervened individuals. |
