In my last blog post 'Walking - The Miracle Cure' I emphasised the benefits of walking and hinted at the need for Walking Plus but why do we need Walking Plus and what do we mean by Plus?
Walking is wonderful but its benefit is primarily on stamina, This aspect of fitness focuses on the body’s ability to get enough oxygen when required to do extra work, and this depends principally on the fitness of the lungs, heart, and circulatory system. The ageing process affects both these systems but for most people affected by breathlessness, the cause is not ageing but a combination of loss of fitness and disease. The heart becomes unfit as a result of inactivity, namely, failure to increase the pulse rate for 30 minutes at least 3 times a week. For the respiratory system, the effects of inactivity and loss of fitness are not so much on the lungs as on structures within the muscle cells, called mitochondria, which extract oxygen from the blood as it passes through. However, for too many people breathlessness is not the consequence of ageing but of disease, heart and lung disease caused by our environment and lifestyle and people who smoke should try to stop no matter how often they have tried in the past and no matter their age. There are however 3 other aspects of fitness – strength, suppleness and skill.
Ageing affects the muscles and muscle strength reduces every year. However, the studies that demonstrate these trends are conducted on people who live the Western lifestyle, so how much of the change that takes place is due to ageing and how much to the loss of fitness is unclear. From studies demonstrating how strength can be increased by training in the seventies and eighties, it is reasonable to assume that a considerable proportion of loss of strength is due to loss of fitness, and is therefore preventable and recoverable. Walking increases the strength of the lower limbs but it is essential to maintain and improve the strength of the upper limbs and the core muscles of your abdominal wall and spine which we will describe later
This is probably the least well recognised aspect of fitness, even in young active sportsmen and sportswomen. Just look at a leg of lamb and you can clearly see white connective tissue surrounding the muscles connecting them to bones as tendons, and connecting the bones to one another as ligaments.
The chemical called collagen, that is in the tissue in tendons and ligaments, loses elasticity with age but, as with the loss of muscular strength, the evidence is derived from the study of people leading a Western, sedentary, lifestyle. Even people who are active at home and work rarely move their muscles, tendons and ligaments through the full range of movements. In societies in which exercise like Tai Chi is universal, however, it is clear that at least some of the loss of suppleness is the result of failure to stretch. In Japan, participation in exercises derived from martial arts such as Kendo are widespread and contribute to its very active society of people over seventy. In the West, the rise of interest in, and evaluation of Yoga, the Alexander Technique, and Pilates classes demonstrate that suppleness can be maintained and improved at any age.
The ability to perform complicated tasks is a skill and although the term is usually used to describe the abilities of a craftsman or artist or pianist, skill is important in everyday life. The ability to stand on one leg while putting a stocking on the other is a skill, as is the ability to estimate and then step accurately from a bus to the pavement, as well as more intricate skills such as sewing, or repairing a fuse box.
Skill requires both muscular strength and coordination by the nervous system, so the skill that is lost as a result of inactivity is another aspect of loss of fitness. However, as with other aspects of fitness loss, loss of skill can be prevented by keeping active and recovered by training, namely, the repetition of the skill, and related activities. For example, to maintain and improve the skill of recovery from a stumble, daily balance exercises, supplemented by social activities such as dancing, maintain and improve the muscular and neurological skills required to recover from a trip on an irregular pavement.
