Document Summary

Any body movement produced by skeletal muscle: that results in energy expenditure, e. g. Any form of physical activity that is undertake with a specific objective: e. g. Any waking activity characterized by an energy expenditure 1. 5 met: or a sitting/ reclining posture. Challenges of measuring pa: pa is a complex construct (fitt, many different types of pa. Relies on the participant telling you: written and interview questionnaires, activity diaries or logs. Actually measuring something: heart rate monitors, pedometers, motion sensors/ accelerometers. Directly measuring pa: direct observation, doubly labeled water. Inexpensive: can be used on large populations, easily analyzed, not time consuming. Advantages: data can be analyzed on a computer. Disadvantages: can"t be used on large populations, heart rate can be affected by other factors, people that are fitter have lower heart rates, doesn"t indicate type of exercise, masks interval work. Disadvantages: only measures certain activities, doesn"t measure stride length, can"t measure intensity, doesn"t indicate type of activity.
