Malaysia is fast becoming an aging nation. The average life expectancy now stands at 74.7 years in 2016 as compared to 72.2 years in 20001. With the average Malaysian living longer, it is important to ensure that these ‘additional years’ are spent in good health.
After the age of 30, the average adult is estimated to lose 3% to 5% of muscle per decade2 due to a combination of factors e.g. aging, sedentary lifestyle, poor nutrition or presence of illness. A decrease in muscle mass and strength over the decades can lead to frailty, reduced mobility, increased risk of falls and fractures. In older adults, it is possible to rebuild those muscle mass through diet and exercise.
Protein from food is broken down during digestion into amino acids which are the building blocks for muscle. Older adults require more protein than younger adults due to reduced ability to break down protein (attributed to aging). The recommended protein intake for average older adults is between 50-60 grams per day3.
Strength training is a good way to improve overall muscle strength. Check with your doctor before you embark on any exercise and approach a well-qualified physiotherapist/trainer to ensure you perform those exercise safely.
Age-related muscle loss is inevitable but it is possible to slow down the process. With adequate protein intake and regular exercise, you can remain strong and healthy in your golden years.
