A simple fitness test, involving standing on one leg, may offer insights into an individual’s lifespan, according to a study published in the British Journal of Sports Medicine. The research indicates that the ability to stand unsupported on one leg for 10 seconds or longer is associated with a lower risk of mortality in middle-aged and older adults.
The study, conducted by researchers in Brazil, tracked participants over several years and revealed a correlation between balance and longevity, highlighting the importance of maintaining physical fitness, particularly balance, as people age. While the test is not a definitive predictor of lifespan, it serves as a valuable indicator of overall health and functional ability.
The research involved nearly 1,700 participants aged 51 to 75 who were followed for an average of seven years. Participants were asked to stand on one leg for 10 seconds without any additional support. To standardize the test, individuals were instructed to place the front of the free foot on the back of the opposite lower leg while keeping their arms by their sides and looking straight ahead.
According to the study, approximately 20% of participants failed the 10-second test. The proportion of individuals unable to complete the test increased with age, with failure rates ranging from about 5% in the 51-55 age group to nearly 54% in those 71-75 years old. During the follow-up period, 123 participants died. Researchers found a significant association between the inability to complete the 10-second balance test and an increased risk of death from any cause. In fact, those who failed the test were 84% more likely to die within the study period compared to those who could complete it.
“This is an observational study, so it can’t establish cause,” Dr. Claudio Gil Araujo, the study’s lead author, told Yahoo Lifestyle. “However, the test adds useful information about mortality risk in middle-aged and older men and women.” Araujo further noted that the ability to successfully complete the test reflects good musculoskeletal fitness, which is essential for maintaining independence and performing daily activities.
The study underscores the importance of balance as a key component of physical fitness, particularly as individuals age. Maintaining good balance helps prevent falls, which are a leading cause of injury and disability in older adults. Regular exercise, including balance-specific training, can improve balance and reduce the risk of falls.
The findings of this study align with previous research highlighting the link between physical fitness and longevity. Studies have shown that individuals who engage in regular physical activity tend to live longer and have a lower risk of chronic diseases, such as heart disease, stroke, diabetes, and cancer.
While the one-leg standing test is a simple and convenient way to assess balance, it is important to note that it is not a substitute for a comprehensive medical evaluation. Individuals who are concerned about their balance or overall health should consult with a healthcare professional.
The study’s authors suggest that the one-leg standing test could be incorporated into routine health checkups for middle-aged and older adults.

Elaborated and Enhanced Content:
The study published in the British Journal of Sports Medicine presents compelling evidence for the correlation between balance, as measured by the one-leg standing test, and overall longevity in middle-aged and older adults. While the study does not establish a direct causal relationship, the significant association between the inability to perform the test and an increased risk of mortality warrants further examination and consideration for integration into routine health assessments.
Methodology in Detail:
The research methodology was carefully designed to assess the balance capabilities of the participants. The near 1,700 individuals, spanning ages 51 to 75, were meticulously instructed on how to perform the one-leg standing test. The standardization included specific positioning of the non-supporting foot (placed on the back of the opposite lower leg), the arms (held by the sides), and the gaze (directed straight ahead). This meticulous approach ensured that the test was conducted uniformly, minimizing variability and enhancing the reliability of the results. Participants were given up to three attempts to successfully complete the 10-second balance, ensuring that the data accurately reflected their maximum balancing ability. The extended follow-up period, averaging seven years, allowed researchers to observe long-term health outcomes and establish a more robust association between balance and mortality.
Statistical Significance and Risk Assessment:
The statistical analysis revealed a highly significant association between failing the one-leg standing test and increased mortality risk. Those who were unable to complete the test exhibited an 84% higher risk of death from any cause compared to those who could successfully balance for 10 seconds. This elevated risk remained consistent even after adjusting for other potential confounding factors such as age, sex, body mass index, and pre-existing medical conditions. The hazard ratio of 1.84 (95% confidence interval, 1.23 to 2.78) indicates the magnitude of this increased risk. These findings underscore the strong predictive value of balance assessment in identifying individuals at higher risk of mortality.
Comparative Analysis with Existing Literature:
This study builds upon a substantial body of existing research that links physical fitness to longevity. Prior studies have demonstrated the benefits of cardiovascular exercise, strength training, and flexibility for overall health and reduced mortality risk. This particular study expands our understanding by highlighting the crucial role of balance, an often-overlooked component of physical fitness. Balance is critical for preventing falls, a leading cause of injury and disability in older adults. Falls can lead to fractures, head injuries, and other complications that significantly impact quality of life and contribute to increased healthcare costs. By identifying individuals with impaired balance, healthcare providers can implement targeted interventions to reduce the risk of falls and improve overall health outcomes.
Physiological Mechanisms Underlying Balance and Longevity:
While the study does not directly investigate the physiological mechanisms linking balance and longevity, several potential explanations can be inferred. Balance relies on a complex interplay of various systems, including the musculoskeletal system (muscles, bones, and joints), the nervous system (brain, spinal cord, and peripheral nerves), and the sensory system (vision, proprioception, and vestibular system). Impaired balance may reflect underlying dysfunction in one or more of these systems. For example, decreased muscle strength or flexibility, nerve damage, or visual impairments can all contribute to balance problems. Moreover, balance is closely linked to cognitive function. Studies have shown that individuals with cognitive impairment are more likely to experience balance problems and falls. The ability to maintain balance requires cognitive resources for attention, planning, and motor control. Therefore, impaired balance may be an early indicator of cognitive decline. Maintaining good balance requires a healthy and well-functioning body. Balance may serve as a marker for the overall health and resilience of the body, reflecting the ability to withstand stressors and maintain homeostasis.
Practical Applications and Recommendations:
The simplicity and accessibility of the one-leg standing test make it a valuable tool for both individuals and healthcare providers. Individuals can easily perform the test at home to monitor their balance and track changes over time. If they are unable to complete the test, they should consider consulting with a healthcare professional to identify any underlying health problems and develop a plan to improve their balance. Healthcare providers can incorporate the one-leg standing test into routine checkups for middle-aged and older adults. The test can be performed quickly and easily in a clinical setting, providing valuable information about a patient’s overall health and risk of falls. Individuals identified as being at risk can be referred for further evaluation and intervention, such as physical therapy, balance training, or medication adjustments. The test can also be used to track the progress of patients undergoing rehabilitation or treatment for balance problems.
