the Benefits of physical fitness
Exercise, physical activity and physical fitness are three sides to a vital aspect of healthy living. This website and blog are designed to review what we know about these factors and the findings of new research in this field. We know plenty but there is still plenty which we do not know or about which there is uncertainty. It is an evolving science – our understanding of the benefits of exercise and physical fitness is continually being updated by the scientists who investigate the subject. This blog will keep you in touch with these developments. It may even persuade the uncommitted to take up or increase their exercising…..Here’s hoping.

THE BLOG
Energy expenditure, health and fitness
Another recap Total exercise dose can be calculated as MET minutes1 or MET hours. And one MET, or metabolic equivalent, is the rate at which energy is used by the body at rest. It is expressed in relation to body weight and is taken as 3.5ml of oxygen per minute per...
Energy Cost of Different Activities
Measuring exercise dose Last week I explained the various ways of measuring dose of exercise and I gave some reasons for wanting to do so. For instance one use is to assess the balance between calories consumed as food and calories expended in physical activity. The...
Measuring the Dose of Exercise
Units of measurement There are many ways of measuring exercise dose and the the best unit of aerobic exercise is the Metabolic Equivalent or MET. This is a measure of the intensity of exercise or physical activity, not total dose. It reflects the rate at which oxygen...
OXYGEN UPTAKE AND TRANSPORT
VO2 and VO2max A few points from last week's Blog as a recap: 1. Aerobic exercise means exercise fueled by oxygen. 2. The rate of oxygen usage is directly associated with the intensity of exercise. 3. The rate of oxygen use is usually expressed as millilitres of...
OXYGEN AND VO2max
Fueling exercise I have described the importance of oxygen for fueling exertion, but it was a long time ago - maybe even before you were reading my blog. It is a fascinating and really important topic if we are to understand some of the mechanisms of exercise so I...
THE INDUSTRIAL REVOLUTION
The mechanisation of work The inevitable consequence of having machinery take over much of manual work was the reduction of the general level of physical activity in the population. While there was a fairly rapid change over the transition period between the late 18th...
