Scientists have discovered that measuring your calves could reveal important insights about your longevity and overall health.
The circumference of a person's calves compared to their body proportions may serve as an indicator for multiple health conditions, including heart disease risk, nutritional health, and death rates.
The relationship between calf measurements and well-being stems from their correlation with muscle mass throughout the body.
More developed calf muscles typically signal superior physical capabilities, particularly among elderly individuals.

Age-related muscle deterioration, medically termed sarcopenia, typically intensifies beyond age 60. It contributes to numerous complications such as impaired movement, higher fall risks, bone fractures, and diminished physical abilities.
Global estimates suggest sarcopenia impacts between 10 and 16 per cent of older adults, with research showing those affected face a 364 per cent greater mortality risk among centenarians compared to individuals maintaining healthy muscle mass.
Medical professionals utilise the waist-to-calf ratio (WCR) as a comprehensive health assessment tool. This measurement accounts for both abdominal fat accumulation and muscle distribution, potentially offering superior health risk evaluation compared to BMI or waist measurements in isolation.
Calculating your WCR involves dividing waist circumference by calf circumference using consistent units. A ratio of 2.4 or below indicates healthy proportions between midsection and lower body composition. Values exceeding 2.4 correlate with elevated cardiovascular and circulatory disease risks.
Chinese researchers analysing 37 studies encompassing 62,736 adults discovered that every centimetre increase in calf circumference corresponded to a five per cent reduction in mortality risk.
Their findings emerged from work conducted at the Chinese Academy of Medical Sciences and Fuwai Hospital in Beijing.
Italian scientists from the Catholic University of Sacred Heart examined connections between calf measurements and physical capabilities in individuals aged 80 and above.
Their research revealed that "physical performance and muscle strength significantly improved" with increasing calf circumference.
The team assessed participants' frailty through walking speed, strength, weight, energy and exhaustion levels.
They found "frailty index score was significantly lower among subjects with higher calf circumference", supporting calf measurements as indicators of muscle mass and fitness.
Italian research involving 8,900 participants established links between WCR measurements and diabetes prevalence.
Average WCR values measured 2.4 for healthy individuals, 2.6 for pre-diabetic patients, and 2.7 for those with diabetes, affecting over 37 million Americans.

The researchers noted that muscle tissue significantly influences glucose processing and metabolic health. They highlighted connections between sarcopenia, insulin resistance, metabolic syndrome and cardiovascular complications.
Chinese researchers tracking 3,312 cognitively healthy participants discovered 565 developed mental decline within three years.
Higher WCR values showed stronger associations with cognitive deterioration than individual measurements.
Medical experts explain that robust calf muscles, especially the soleus, facilitate blood circulation to the heart. This mechanism supports healthy blood pressure and cerebral blood flow, essential for maintaining cognitive abilities.
