A new study conducted by the Mayo Clinic suggests that the ability to stand on one leg for an extended period of time may be a more accurate indicator of aging than changes in strength or gait. The research, published in the journal PLOS ONE, focused on the relationship between balance and aging and how it impacts overall health and independence as people get older. By studying a group of 40 healthy individuals over the age of 50, researchers found that balance, along with muscle strength and gait, play a crucial role in ensuring healthy aging.
The participants in the study underwent a series of tests to assess their balance, grip strength, knee strength, and gait. The balance tests involved standing on force plates in various positions, including on both feet with eyes open or closed, and on one leg with eyes open. The results showed that standing on one leg, specifically the nondominant leg, exhibited the highest rate of decline with age. Poor balance can increase the risk of falling, which can have severe consequences for older adults.
In addition to balance, grip and knee strength were also measured in the study. Grip strength decreased at a faster rate than knee strength, making it a better predictor of aging. However, gait parameters did not show any significant changes with age, as participants were walking at their normal pace. The study did not find any sex-specific differences in the strength, gait, or balance tests, indicating that both male and female participants were equally affected by aging.
According to Dr. Kenton Kaufman, the senior author of the study, individuals can take steps to train their balance and maintain their overall health. Simple exercises, such as standing on one leg for 30 seconds, can help improve coordination and muscle responses to maintain correct balance. Dr. Kaufman emphasizes the importance of using these abilities regularly to prevent their decline with age. The findings of this study provide important insights into the factors that contribute to healthy aging and independence among older adults.
Funding for the study was provided by the Robert and Arlene Kogod Professorship in Geriatric Medicine and the W. Hall Wendel Jr. Musculoskeletal Professorship. The research highlights the importance of balance, grip strength, and knee strength in assessing aging and provides valuable information for clinicians working to develop programs to promote healthy aging. By incorporating simple exercises to improve balance and strength, individuals can take proactive steps to maintain their independence and well-being as they age.
