Articles on Fitness

Fitness can be described as the ability to perform daily tasks vigorously and alertly, with energy left over for enjoying leisure-time activities and meeting emergency demands. It is the ability to endure stress, to continue on in circumstances where an unfit person could not continue and is the basis for good health and well-being.

Physical fitness involves the performance of the heart, lungs and the muscles of the body. What we do with our bodies also affects what we can do with our minds.  Fitness can influence, to some degree, mental alertness and emotional stability.

Walking can cut stroke risk in women

Stroke can be a disabling, even fatal, event. We already know about some of the risk factors linked to stroke, such as high blood pressure, excess alcohol intake, diabetes and smoking. What has not been clear is how physical activity might help reduce stroke risk. A team from Harvard School of Public Health now issues a new report from the Women’s Health Study, a large study set up to investigate risk factors and heart disease and stroke. This shows an association between walking for two hours or more a week and reduced stroke risk. Read more

Preventing weight gain through exercise

The equation for weight gain is a simple one – if calories in (through food) are greater than calories out (through exercise) then you will gradually gain weight. Therefore, exercise clearly plays an important role in balancing the equation, preventing weight gain and maintaining a healthy weight. But, the big unanswered question is – can you stay trim by exercise alone, if you do enough? A new study from researchers at Harvard Medical School, and elsewhere, set out to provide some answers.

Dangers of a sedentary lifestyle highlighted

The sedentary lifestyle is marked by prolonged periods of sitting, whether it’s lolling around in front of the television or being glued to a computer screen at work. A new study reveals that the sedentary lifestyle carries health risks that go beyond the mere fact that when you are sitting you are not taking exercise. The muscular inactivity that goes with the sedentary lifestyle is linked to obesity, diabetes, heart disease, cancer and an overall higher mortality, say researchers at the Karolinska Institute, Sweden. It is possible to quantify the risk – for each additional hour a woman sits in front of the television, her risk of metabolic syndrome goes up by 26% and this is independent of whether or not she takes exercise at other times. The researchers say we should take sedentary lifestyle to mean muscular inactivity rather than lack of exercise – a subtle difference, perhaps, but an important one. Read more
