Obesity, a major risk factor in the development of type 2 diabetes and increased morbidity and mortality, has increased rapidly in recent decades. Exercise represents an important intervention for weight loss through the potential to raise energy expenditure. Exercise intensity plays an important role in governing substrate utilization (i.e., fat and carbohydrate) during exercise. Commonly, low/moderate intensity exercise is recommended for overweight and obese individuals to promote fat oxidization. Low/moderate intensity exercise is also proposed to be an appropriate intensity for preventing injury and improving tolerance. The reason to use this level of exercise intensity is to ensure that sedentary overweight/obese individuals could maintain the duration of exercise sessions.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
