The second installment from Harry Smith in our Reasons to run series, a retired GP and keen runner who regularly attends Running Past 50 on a Friday morning here at the Accelerate store. Harry shares the medical benefits of exercise and how it can keep you healthy and strong whatever your age.
Thomas Edison 1847 – 1931 said “The doctor of the future will give no medicine but will involve the patient in the proper use of food, fresh air and exercise.”
Running is one of the best ways to keep fit and boost your overall health. It is a social activity enjoyed in an outdoor environment by thousands.
The Health benefits are numerous.
1. Cardiovascular System ‘A runner must run with dreams in his heart.’ – Emil Zatopek
The heart is a muscle and like any other muscle in the body benefits from regular exercise. Exercise lowers blood pressure. High blood pressure is a major causative factor in heart attacks. Good HDL cholesterol transports fat away from the arteries and back to the liver for processing is increased by exercise which may also reduce levels of bad LDL cholesterol which causes arteriosclerosis, Arteries therefore retain their elasticity.
This increase in cardiovascular health is asso ciated with a decrease in the incidence of strokes, heart attacks and coronary heart disease
2. Respiratory System “Just breath.” Author unknown
Our lung capacity naturally declines with age. Exercise can increase lung capacity by 5 -15% (lung capacity is the amount of air your lungs can hold after one inhalation). Running thus leads to increased efficiency of the lungs better facilitating transport of oxygen to all body cells leading to better stamina and more work for less cardiorespiratory effort.
3. Muscular Skeletal system. “Be fluid and elegant in your movements.” Anonymous
Running and running coaching especially can improve joint strength, mobility, and function. Muscles are strengthened and bone loss reduced. Core exercises train muscles in the pelvis, lower back, hips, and abdomen to work in harmony, leading to better balance and stability in daily activities.
Sufferers from arthritis also benefit from appropriate exercise reducing pain and increasing range of movement. The incidence of falls is reduced.
4. Weight Loss. “Sweat is just fat crying” anonymous.
Exercise is the key to weight control. Running for one hour can burn 400 calories. Running is the second-best exercise for burning calories, only second to cross country sking. However, for losing or maintaining a constant weight a balanced diet is also required. Exercise also lowers the incidence of diabetes by 50% by allowing muscles to better process glycogen, afuel for energy. Impaired processing of glycogen leads to excessive blood sugar and thus Diabetes
5. Psychological “Exercise equals endorphins. Endorphins make you happy” Anonymous
Beta-endorphin is released into the circulation from the pituitary gland during exercise,This improves mood and promotes a feeling of wellbeing thus boosting confidence and self-esteem.
Setting and achieving goals can give a sense of empowerment that leaves one feeling happier so fighting depression and stress.
Running is good at increasing social interaction since the running community has many supportive individuals and clubs.Aging is delayed as brain cognitive functions are maintained and decline prevented. New brain cells (Neurogenesis) are also created. There is an increase in vocabulary retention. with better decision making and learning.Miscellany Exercise has also been shown to have the following effects
In summary. Running is incredibly beneficial to the body and the mind. It can leave you feeling more energised, fitter, more focused and better able to enjoy all life has to offer.
Promoting regular running will bring us nearer to Thomas Edison’s prediction.
