Despite common beliefs, the prime causes of tightness and soreness in muscles of the back, hips, and legs is not diseases such as arthritis. In order of frequency, the troublemakers are:
At the Colgan Institute we have found consistently, that the muscles and fascia attached to the weight-bearing skeleton of the lower back, hips and legs, are the most commonly tight and most commonly cause pain and restriction of movement.
This booklet shows you how to test your flexibility in these areas, so that you will know which stretches are the ones you need to concentrate on.
The length and elasticity of your muscles, and the freedom of motion of your joints, are mostly shaped by the habitual movements you make. If you do any type of repetitive partial movement, such as jogging, you progressively shorten and tighten the prime movers, in this case, the quadriceps and the hamstrings.
In addition to wrong aerobic training and wrong weight training, wrong stretching also makes you tight. If you stretch as we see many folk doing, trying to lengthen a tight muscle instead of relaxing the muscle chain, all you achieve is tightening of other muscles in the chain, plus the surrounding stabilizers, with the net result of further reduced mobility.
This booklet goes over the essentials of stretching and how to assess your posture and its problems.
Average life expectancy in the United States is 77.2 years, in Canada it is 79.7. In 1999 the World Health Organization began to rank countries NOT by average life expectancy, but by HEALTHY life expectancy, that is total life expectancy minus the average years before death during which most aged people suffer serious disease or disability. Different research organizations now use the terms: Disability-Adjusted Life Expectancy or Health Adjusted Life Expectancy.
No one wants to live as a doddering geriatric with one foot in the crematorium. We all want Healthy Life Expectancy - and most of us would like to know our chances. The Colgan Longevity Scale aims to tell you. Even more important, it also aims to give you strategies to improve your scores, so that you may live a healthy lifespan that far surpasses the average.
