What Happens to Our Fitness As We Age....
We lose about 0.5kg of muscle mass every year during our 30s and 40s and this rate may double after 50. This gradual process of muscle loss is called sarcopenia and is masked by increasing fat levels.
Peak bone mass is achieved by about age 25. Post mid-30s bone mass is lost at a rate of about 0.5 – 1% per year. From the onset of menopause women experience a period of accelerated bone density loss of up to 3 – 5% per year for up to seven years.
The benefits of resistance and aerobic training include reducing the risk of cardiovascular disease and hypertension, type 2 diabetes, obesity, stroke, osteoporosis, some types of cancer, psychological stress and depression.
Functional training and active daily living will also improve balance, reaction times and confidence as people age. Additionally, exercise can improve sleep, digestion and increase metabolic rate.
No other age group can experience more health benefits from exercise than those over 50.
