Scientists at the Mayo Clinic conducted a study on 40 participants over the age of fifty. The research examined grip strength, knee strength, gait, and balance tests, revealing surprising results.
The results show that while walking is not significantly affected by age, balance deteriorates noticeably. The study highlights that balance relies on various systems, including the visual and vestibular systems.
It was found that the duration one can balance on one leg decreases by 2.2 seconds each decade. As for bilateral tests (on two legs), postural instability increases by 6.3% per decade with the eyes open and 10.4% with the eyes closed. These numbers are alarming when considering aging and the risk of falls.
Sarcopenia, defined as the loss of muscle strength and mass, affects nearly 15% of people over 45 in France, and between 20% and 35% of those over 75. Researchers emphasize the importance of maintaining regular physical activity to prevent this condition and the risk of falls.
A simple exercise, like standing on one leg for 30 seconds, may be enough. This daily exercise helps coordinate muscular and vestibular responses, thereby strengthening balance. Researchers recommend testing this ability regularly to assess one's health.
It is thus possible to measure your biological age by evaluating your ability to maintain balance. Scientists suggest that people aged 69 and younger should be able to stand on one leg for at least 30 seconds.
The test requires no equipment and can be performed at home, making it a practical health indicator. Good balance is essential for living an active life and avoiding injuries.
What is sarcopenia and why is it important?
Sarcopenia is a natural process of muscle mass, strength, and coordination decline that occurs with age. This phenomenon typically begins at around 30 years old, accelerating after 60, and significantly impacts the quality of life of older individuals.
In France, sarcopenia affects about 15% of people over 45 and can reach up to 35% of those over 75. The consequences of this condition include reduced mobility, an increased risk of falls and fractures, and a loss of autonomy. Maintaining regular physical activity is essential to counteract this muscular deterioration.
