Reduced muscle mass, blood cell production, flexibility, bone mineral density. Decline in cardio respiratory function. Increase in blood pressure. Respiration becomes more difficult. Poor posture. Decrease in the number of nerve cells.
Some of the outcomes of the above
Reduced metabolic rate, muscle tone and strength, balance and stability, range of movement, aerobic capacity. Altered gait. Greater risk of falls, osteoporosis, arthritis and joint pain. Many activities of daily living become more difficult. Premature fatigue and tiredness. Lowered immune system.
The good news!
All of the above can be reduced significantly and to some extent reversed.
Hope the above explains why we do what we do in class.
