Knee injuries are the most common injury for athletes, and often result from weak muscles, overuse, or impact. Athletes need to strengthen their knees to stay in the game.
Strong knee muscles – quadriceps, hamstrings, and glutes – are key to injury prevention, stability, and overall performance. Proper knee strengthening exercises protect the ligaments around the knee joint and improve range of motion, flexibility, and power during athletic movements.
If you can’t do traditional strengthening exercises because of knee pain or injury, Motive is a great alternative to strengthen the muscles around the knee with minimal strain. Our app-controlled, FDA-cleared therapy can help athletes in their recovery journey.
In this article, we’ll cover knee-strengthening exercises for athletes to build strength and stability.
Common Knee Injuries in Athletes
Athletes across all sports are susceptible to knee injuries due to the stress and impact on their joints during activity. Below are some of the most common knee injuries in sports.
1. ACL Tears
The anterior cruciate ligament (ACL) is a ligament that stabilizes the knee joint. ACL injuries are common in high-impact sports like soccer, basketball, and football where athletes are constantly pivoting, jumping, and changing direction. An ACL tear can occur when the knee is twisted beyond its range of motion or hit with sudden force.
Strengthening the quadriceps, hamstrings, and glutes can help prevent ACL injuries by improving knee stability and controlling the movements that lead to tears.
2. Patellar Tendonitis (Jumper’s Knee)
Athletes who play sports that require repetitive jumping like basketball and volleyball are at risk for patellar tendonitis also known as jumper’s knee. This occurs when the patellar tendon, which connects the kneecap to the shinbone, becomes inflamed due to overuse.
Strengthening the quads and hamstrings distributes the workload during activities like jumping and reduces the strain on the patellar tendon. Exercises focusing on controlled movements and knee flexion can also help athletes avoid overloading the tendon.
3. Meniscus Tears
The meniscus is the cartilage that cushions and stabilizes the knee. It’s highly prone to injury during twisting or squatting movements, especially in sports like rugby and tennis. A meniscus tear occurs when the knee is twisted or lands awkwardly.
Strong knee muscles – especially hamstrings and hip flexors – can absorb shock, stabilize the joint, and reduce the risk of meniscus injuries.
Working on hamstring stretches and controlled flexion movements can keep the knee flexible and protected during high-intensity movements.
4. IT Band Syndrome
The iliotibial (IT) band is a thick tendon that runs from the hip to the outside of the knee. IT band syndrome is common in runners and cyclists and is caused by repetitive knee motion. This can cause inflammation and pain on the outside of the knee.
Strengthening the glutes, quads, and hamstrings will help stabilize the knee joint and correct any misalignment that could be contributing to IT band syndrome. Flexibility exercises like hamstring stretches and hip width movements will also help prevent tightness in the IT band.
The Importance of Knee Strength for Athletic Performance
Having strong knee muscles is essential for optimal athletic performance.
Here’s how knee strength affects your performance in specific sports:
-
Power: Athletes generate power from their lower body and the knee joint is at the center of that. Strong quads, hamstrings, and glutes are the foundation for explosive movements like jumping, sprinting, and lifting. For sports like track and field, basketball, and weightlifting, being able to push off the ground with force is key to performance and that starts with strong knee muscles.
-
Agility: In sports like soccer, tennis, and football, agility is key for quick changes of direction, sidestepping opponents, and balance during rapid movements. Strong knee muscles provide stability for these lateral movements and reduce the risk of injury. Athletes with stronger quads and hamstrings can stabilize the knee joint during these movements and have better control over their body to move freely.
-
Speed: Speed is important in almost every sport from running to cycling to team sports like basketball or soccer. Athletes use their knees for the repetitive motion of running and knee strength plays a big part in stride efficiency and endurance. Stronger knee muscles, especially the hamstrings, calves, and glutes reduce fatigue during long sprints or distance running and allow athletes to maintain top speed for longer.
Here’s how it can make an impact in individual sports:
-
Basketball and Volleyball: Athletes need strong knees for repetitive jumping. Quad and hamstring exercises are key to building leg power for high jumps, quick sprints, and landing safely without putting stress on the knee joints.
-
Soccer and Tennis: These sports require quick direction changes, constant movement, and lateral agility. Single-leg exercises like step-ups and lunges improve knee stability and allow athletes to pivot, accelerate, and decelerate smoothly.
-
Running and Cycling: Endurance athletes need strong knees to handle the repetitive stress of running or pedaling. Exercises that target the hamstrings, quads, and calf muscles ensure long-term knee stability, reduce the risk of knee pain, and improve performance through efficiency and reduced injury risk.
