How Fitness, Strength, and Balance Can Help Prevent Joint Problems
Share
Introduction
Many people suffer from joint and bone problems as they get older. These are known as musculoskeletal disorders (MSDs) and include conditions like arthritis and back pain. But did you know that how active and fit you are today can play a big role in whether you develop these problems in the future?
A large new study involving over 400,000 adults in the UK found that low physical activity, poor fitness, weak grip strength, and even imbalanced hand strength are all linked to a higher risk of developing MSDs. The good news? Improving these factors may help protect your joints and muscles for years to come.
What Are Musculoskeletal Disorders (MSDs)?
MSDs are problems that affect the muscles, bones, and joints. Common examples include:
- Rheumatoid arthritis (RA) – an autoimmune condition that causes joint pain and swelling.
- Osteoarthritis (OA) – wear and tear in the joints, especially in older people.
- Degenerative spinal diseases (DSDs) – conditions that cause back pain and limited movement.
These disorders can cause serious pain, reduce mobility, and make daily activities difficult.
What Did the Study Look At?
Researchers tracked 406,080 adults aged 37–73 years who didn’t have MSDs at the start. Over nearly 15 years, they looked at several health and lifestyle factors:
- Physical activity (PA): how much people moved each week.
- Cardiorespiratory fitness (CRF): how well the heart and lungs worked, measured through exercise.
- Grip strength (GS): a measure of how strong a person’s hands were.
- Grip strength balance: whether a person’s left and right hands were equally strong.
They then checked who developed MSDs and looked for patterns.
Key Findings
- Low physical activity increased the risk of developing MSDs. People who exercised the least were more likely to suffer from arthritis and back issues.
- Poor fitness (low CRF) was linked to a higher risk of joint problems. Even small improvements in fitness lowered the risk.
- Weak grip strength meant a higher chance of developing MSDs. Those with the weakest grip had up to a 32% higher risk of rheumatoid arthritis.
- Imbalance between hands (grip strength asymmetry) also raised the risk. People whose hands were not equally strong were more likely to get joint disorders.
Interestingly, the study found that both very low and very high levels of physical activity could increase risk. The best outcomes were seen in people who did a moderate amount of activity.
Why These Findings Matter
This study is important because it shows that MSDs are not just a part of aging—they are linked to lifestyle choices that we can change. Staying active, improving heart and lung health, strengthening muscles, and maintaining balance between the left and right sides of the body can help prevent these painful and disabling conditions.
Even small efforts, like increasing walking speed or using both hands equally in daily tasks, can make a difference.
What You Can Do
Here are some simple steps you can take to protect your joints and muscles:
- Move more: Aim for at least 150 minutes of moderate physical activity per week. Walking, dancing, cycling, or gardening all count.
- Build your fitness: Try activities that increase heart rate, like brisk walking or swimming. Even a short daily walk helps.
- Strengthen your grip: Use hand grips or squeeze a ball regularly. Activities like lifting groceries or doing chores also help.
- Balance both sides: Try using your non-dominant hand more often—for example, when brushing your teeth or opening jars.
- Avoid overdoing it: Very high levels of intense exercise may not always be better. Find a balanced routine that fits your body and lifestyle.
Final Thoughts
Muscle strength, fitness, and balance aren't just for athletes—they're key to staying healthy and pain-free as we age. This study offers powerful evidence that taking care of your physical health today can help prevent serious problems tomorrow. So whether you're already active or just starting, every small step counts toward keeping your joints strong and your future bright.
