Movement is essential to good health. It improves cardiovascular health, and lowers the risk of developing type 2 diabetes, and it can also boost mental health.
While research shows that cardiovascular and strengthening exercises can increase one’s lifespan, flexibility was largely left unaddressed. This led researchers in the current study to analyze whether flexibility plays a role in longevity.
Flexibility refers to, “the range of motion of muscle and connective tissues at a joint or group of joints.”It is important to maintain good flexibility in different areas of the body to avoid or reduce pain in areas such as the neck and lower back. When flexibility decreases, this can cause areas of the body not to work properly.
For example, if someone experiences lower flexibility in their hamstrings, this can lead to tight hamstrings. When this happens, it can cause pain in the thighs that can work its way up to the lower back and reduce mobility.
People can avoid losing flexibility with a daily stretching routine that targets specific areas of the body or by participating in yoga.
Checking Flexibilty across 20 Areas of the Body
The study utilized data collected from the CLINIMEX Exercise open cohort in Brazil. The researchers analyzed data from 3,139 middle-aged people (66% of the group were men) aged 46-65 years when they underwent their first exam.
At the participants’ first exams, the clinicians collected data on their BMI, vitals, and any health issues.
The clinicians also administered a flexibility test called the “Flexitest” that checked how flexible the participants were in 20 body joint movements:
- ankle (two)
- shoulder (five)
- knee (two)
- trunk (three)
- wrist (two)
- hip (four)
- elbow (two)
They assigned a “Flexindex” score from 0 to 80 based on the flexibility of the participants. Each body movement could get a score from 0 to 4 on the 20 areas measured, and lower scores indicated lower flexibility.The clinicians assessed flexibility in several ways, including checking to see how far the participants could extend their elbows, checking their trunk flexion, and assessing how well their shoulders rotated.
The study lasted from March 1994 to February 2023, and the participants’ average follow-up period was approximately 13 years.After analyzing the data, the researchers found that people with better flexibility levels had better survival rates for deaths related to natural or non-COVID causes.
When comparing Flexindex scores between men and women, they found that women had generally higher scores compared to men. Women had a 35% higher Flexindex score on average.
Overall, the scientists saw a connection between higher Flexindex scores and improved mortality rates in both men and women.
When comparing the women with lower Flexindex scores to those with higher scores, the researchers saw that women with lower flexibility scores had a 4.78 times higher chance of dying. The men with lower Flexindex scores had a 1.87 times higher chance of dying compared to those with higher scores.
The study emphasizes the importance of physical fitness, especially in terms of focusing on flexibility and long-term health. It establishes that people—particularly middle-aged people—need to incorporate a daily routine that targets stretching and shows that doctors may need to focus on flexibility at annual physicals.
“An assessment of body flexibility using the Flexitest may serve as a useful complement to routine evaluation protocols for providing exercise recommendations and prescriptions to healthy and unhealthy middle-aged individuals,” write the authors.
