At least two thirds of the adult population are estimated to be insufficiently physically active for optimal health benefits. All initiatives designed to increase physical activity are therefore urgently needed. The well proven health benefits of regular, moderately intense physical activity (Health Enhancing Physical Activity, such as decreased risk of mortality from cardiovascular diseases, seem to apply to all people, regardless of their age, gender and weight. There is moderate evidence indicating that lower physical activity levels, or lack of high intensity exercise, are associated with greater body weight gain over time. On the other hand, recent findings strongly suggest that the amount of inactivity (i.e. time spending sitting, lying, and standing) in the population does not explain body weight. Current recommendations on physical activity that enhances health suggest that half an hour of moderately intense physical activity on most days of the week yields major health benefits for inactive populations. For effective prevention of overweight and obesity, up to an hour of such daily activity is recommended. Recent guidelines also encourage performing regular strength and flexibility training in addition to the 30 minutes of moderate intense activity, or 20 minutes of vigorous exercise three times per week. Thus, recommendations on health enhancing physical activity now approach the recommended exercise levels for developing and maintaining cardio-respiratory and muscular fitness. The message for health promotion is that “higher intensity is back”

THE EPIDEMIOLOGIC STUDY of any concept or event requires that the item under investigation be defined and measured. The common and professional uses of the terms “physical activity,” “exercise,” and “physical fitness” reveal a need for clarification. This paper, therefore, defines physical activity, exercise, and physical fitness, with the hope that each definition will provide a framework in which studies can be interpreted and compared. Ideally, standardized terminology will promote greater understanding of the relation between physical activity, exercise, physical fitness, and health. However, they are often confused with one another, and the terms are sometimes used interchangeably. This paper proposes definitions to distinguish them.

The aim of this study was to investigate the relationship of short term memory and long term memory with blood glucose level in elderly patients with NIDDM. Only 30 male diabetic type II subjects were selected from different places in West Bengal randomly for this study whose age range from 45 to 55 years. Only Fasting blood glucose level, short term and long term memory were measured for this study. Glucometer was used for the measurement of blood glucose level and short term and long term memory tests scale were used for this study. Pearson product moment Coefficient correlation method was used to find out the relationship of short term memory and long term memory with blood glucose level in elderly patients with NIDDM. In conclusion negative relationship was observed between memory and blood glucose level. Maintaining safe blood glucose levels are strongly recommended
