Achieving Health through Physical Activities

Being physically active is important to our overall health and well-being. For this reason, the US Health & Human Services Department recently issued guidelines for physical activities. These guidelines are based on the research conducted by the Physical Activity Guidelines Advisory Committee, a group comprising of 13 leading experts in the field of exercise science and public health.

History of Physical Activity Guidelines

In 1995, the Centers for Disease Control and Prevention and the American College of Sports Medicine issued guidelines on physical activities, which were supported by the Surgeon General. The recommendation called for accumulating moderate-intensity activities at least 30 minutes a day, most days of the week. These new guidelines affirm the recommendation in general, but allow more flexibility in achieving the activity levels required.

Physical activities & Health

The study found that regular physical activities can improve health and prevent certain chronic diseases. Generally, the amount of benefits increases as the amount of exercises increases, especially at low level of activities. Some of the benefits can be observed in a few weeks, while others may take years to build up.

Observed benefits include:

  • Reducing premature death

  • Improving cardio respiratory, metabolic, musculoskeletal and mental health

  • Providing better handle on obesity and energy balance

  • Improving functional ability and preventing falls

  • Reducing risk on certain kinds of cancer
