Regular
Physical Exercise
Typically, after 25 years, muscle mass starts decreasing by 3% to 5% per decade (every 10 years). This reduction
can lead to total degeneration in some individuals. However, with regular and appropriate exercise, anyone,
whatever their age, can increase muscle strength by 25% to 35%.
As a Harvard University scientist, Anne Fabiny, has said, "Physical activity is what is closest to the fountain of
youth!” In her paper,
Living Better, Living Long, Fabiny said, with supporting research, that physical activity reduces the risk of being
affected by various diseases: diabetes, cancer, Alzheimer's, cardiovascular disease, osteoporosis, depression, and
others. Exercising regularly
keeps bones healthy, helps maintain vitality and independence even in elderly people. In addition, regular exercise
improves mood and mental functioning. Physical activity can counteract, to some extent, the negative effects of
certain risk factors for cardiovascular disease like high blood cholesterol and hypertension.
Regular physical exercises well suited to your age and physical condition, can also significantly reduce
non–life-threatening problems
that affect the quality of life. This list includes but not limited to tendonitis, stiffness, loss of range of
motion, minor or mild pain, lack of strength or breath, accidental fall.
Living a sedentary life, however, increases the risk of a variety of disease and premature death. According to
research conducted among 50 000 nurses for six years: more these people spend hours per day watching television,
the higher the frequency of type 2 diabetes increased.
Physical activity needs not to be intense; it can be an everyday activity: fast walking, climbing and descending
stairs, gardening (which also allows you to breathe fresh air), running errands and doing chores, playing with
children, etc. In other words, being moderately active at least 30
minutes per day can be sufficient to help all your organs work normally.
As long as it
is possible, you can combine, within a week, these various activities in your exercise program:
- Stretching
- for joint support
- Strength
training - for muscle tone
- Prolonged
aerobic training – this improves oxygen
transport to the muscles.
