One early morning, the sun is warm, you put on your sneakers, and you run down the tree-lined path. Your heart is beating vigorously, you feel energized, and the energy of the day starts here. Running, this seemingly simple activity, not only exercises our body, but also brings us spiritual enjoyment. But, did you know that while enjoying the benefits of running, your knees may be quietly "hurting".
Yes, you heard it right. While running is an excellent aerobic exercise that boosts your heart and lungs and improves your fitness, it can also be a "hidden killer" of your knees. Especially for our middle-aged and elderly friends, if there is no correct method and moderate amount of exercise, the hobby of running may cause damage to the knees. The knee is one of the largest and most complex joints in the body, and it bears the weight of our body and the impact of movement. Excessive or improper running can lead to knee injuries, which can affect our daily life and ability to exercise.
The knee joint, the silent supporter of your body
The knee joint, as the largest and most complex joint in our body, plays a key supporting role. Its health is directly related to our ability to walk and exercise. Understanding the structure and function of the knee joint is essential to prevent and reduce knee injuries from sports such as running.
The main structure of the knee joint
Bones: The knee joint is made up of the femur, tibia, and patella. These bones interact with each other as they move, providing support and flexibility.
Cartilage: The cartilage in the knee is a smooth tissue that covers the ends of the bones, reducing friction between bones and cushioning impacts.
Ligaments: Ligaments are strong fibrous bands that connect bones, they help stabilize the knee joint, control range of motion, and prevent joint misalignment.
Synovial fluid: Synovial fluid is present inside the knee joint, which lubricates the joint and reduces friction during exercise.
Function of the knee joint
The knee joint is not only the basis for us to walk, it also plays a central role in many sports such as running and jumping. With each step you walk or run, your knee joint is subjected to forces that are several times your body weight. This pressure is fundamental to the proper functioning of the knee joint, but excessive stress can lead to injury.
The relationship between exercise and the knee joint
Moderate exercise can strengthen the muscles around the knee joint and increase joint stability and flexibility. However, excessive exercise, especially long runs, can put too much stress on the knee joint, accelerate the wear and tear of cartilage, and increase the risk of injury.
The warning behind the passion for sports: excessive running hurts your knees
Exercise is key to staying healthy, but excessive running can take a toll on your knees. This section is designed to provide in-depth and practical information to help athletic friends understand and prevent possible knee injuries.
The relationship between excessive exercise and the knee joint
The knee joint is one of the largest and most complex joints in the body, and it bears the weight and impact of the body when walking and running. When you run more than your knee can handle, it can cause excessive wear and tear on your knee. The cartilage in the knee gradually degenerates, causing pain and swelling, which is a common symptom of excessive exercise. In addition, long-term repetitive exercise loads can also lead to ligament strains or meniscus injuries.
Recognize signs of excessive exercise
Persistent pain: Knee pain increases after exercise.
Swelling and stiffness: especially in the morning after getting out of bed or sitting for long periods of time.
Limitation of movement: Feeling like you can't bend or straighten your knees freely.
How to prevent knee injuries
Moderate exercise: Do what you can and avoid overdoing it.
Running technique: Adopt the correct running posture to reduce the impact on the knee joint.
Strengthens muscles: Strengthens the legs and core muscles to support the knee joint.
Rest: Give your body enough time to recover.
Coping methods
Once knee pain occurs, you should reduce the amount of running and seek medical advice. Mild symptoms may be relieved by physical therapy, ice, rest, and appropriate exercise adjustments. Severe injuries may require medical intervention.

Early Signal: A Knee Alert Not to Be Ignored
When we talk about the effects of exercise, especially running, on the knee, it becomes crucial to understand and identify the early signs of knee injury. As one of the largest and most complex joints in the human body, the health of the knee directly affects our athletic ability and quality of life.
Knee pain: The most common early sign is knee pain. This pain may occur after activity, especially after a long run or stair climb. The pain may be dull or sharp and stabbing and usually indicates some level of injury or pressure on the knee joint.
Swelling of the knee: Another important sign is the swelling of the knee. This usually occurs when there is an increase in fluid inside the joints and may be due to an inflammatory response due to overuse. Swelling not only makes the joint appear swollen, but it can also be accompanied by pain and a decrease in the joint's range of motion.
Joint stiffness: You may feel knee stiffness after a period of rest, especially when you wake up in the morning. This feeling of stiffness is often a sign of joint inflammation and a possible injury to the knee.
Limitation of motion: When you notice that your knee has limited range of motion, such as difficulty bending or straightening it completely, it could be a sign of damage to the internal structures of the joint, such as the meniscus or ligaments.
Why are these signals important?
Identifying these signals early is crucial, as they can be a precursor to a more serious problem. For example, long-term neglect of knee pain can lead to chronic arthritis, which in turn can seriously affect quality of life. Early intervention can be effective in reducing pain, slowing the rate of joint degeneration, and in some cases even avoiding surgery altogether.
How to respond to these early signs?
Reduce the amount of exercise appropriately: As soon as these signals are recognized, reduce the amount of exercise that affects the knees, especially running and other high-impact sports.
Seek medical advice: If pain or swelling persists, it is advisable to consult a doctor. Your doctor may recommend physical therapy or anti-inflammatory medications.
Strengthen the muscles around the knee: Strengthening the thigh and calf muscles with specialized exercises can help stabilize the knee joint and reduce the risk of injury.
Improve daily Xi: Avoid staying in the same position for long periods of time, especially squatting and kneeling, which can increase the strain on your knees.
