Slider Progressions: Lie on your back with your feet on a towel or slider. Bend your knees and slide your feet towards your hips, then extend them back slowly. Perform 2-3 sets of 10-15 repetitions.
-
Feet-Elevated Long Lever Bridges: Lie on your back and place your heels on an elevated surface like a chair. Lift your hips towards the ceiling, creating a straight line from your shoulders to your knees. Hold for a few seconds, then lower slowly. Perform 2-3 sets of 10 repetitions.
-
Hamstring Curls with Exercise Band: Attach an exercise band to a sturdy object and loop it around your ankle. Stand with your knees slightly bent and curl your heel towards your buttocks against the band's resistance. Perform 2-3 sets of 10-15 repetitions per leg.
- Prone Hamstring Contractions: Lie on your stomach with your legs straight. Gently contract your hamstrings, lifting your heel slightly off the ground. Hold for 5-10 seconds and repeat 10 times per leg.
Gentle progression and careful monitoring of the knee's response are essential. Start with low resistance and short durations, gradually increasing as strength and tolerance improve. Consistent assessment of swelling and discomfort allows for timely adjustments, ensuring safe and effective hamstring strengthening during ACL rehab.
Advanced ACL Strengthening Exercises
Transitioning to advanced ACL strengthening exercises is a pivotal step for individuals who have successfully moved through initial rehab stages. These exercises are designed to enhance knee stability, improve dynamic balance, and prepare the knee for more demanding physical activities.
Dynamic balance and plyometric exercises play a crucial role in advanced ACL rehab. They help in restoring proprioception, which is the body's ability to sense movement, action, and location. Plyometric exercises, such as jumping and landing drills, build explosive power and improve neuromuscular control. These exercises also train the knee to handle rapid changes in direction and high-impact activities, reducing the risk of re-injury.
- Bilateral Landings: Start with feet shoulder-width apart. Jump up and land softly on both feet, bending your knees to absorb the impact. Perform 3 sets of 10 repetitions.
- Bilateral Plyometrics: Begin in a standing position. Perform continuous jumps, focusing on soft landings and quick take-offs. Aim for 2-3 sets of 10-15 jumps.
- Unilateral Jumping and Landing: Stand on one leg and jump forward, landing on the same leg. Maintain balance and control during the landing. Do 2-3 sets of 8-10 repetitions per leg.
- Unilateral Plyometrics: Perform single-leg hops in place, maintaining a soft landing and quick rebound. Execute 2-3 sets of 10-12 hops per leg.
- Sport-Specific Drills: Incorporate movements that mimic your sport, such as lateral shuffles for basketball or sprint starts for track. Perform 3 sets of 10-15 repetitions.
Integrating these advanced exercises into a regular routine should be approached gradually. Typically, these exercises can be performed 3-4 times a week, with a focus on proper technique and controlled movements. As strength and stability improve, the intensity and volume can be increased.
