5 tips to prevent an ACL injury

Physio and researcher Mel Haberfield shares her warm-up and strengthening exercise tips to help prevent anterior cruciate ligament (ACL) injuries.

The anterior cruciate ligament (ACL) runs diagonally in the middle of the knee and provides rotational stability to the joint.

The ACL is put under a lot of pressure during high-intensity sports and can sprain or tear. However, building the right warm-up and strengthening exercises into your training routine can reduce your risk.

AFLW physio and researcher Mel Haberfield shares her top 5 tips to prevent ACL injuries.

1. An active warm-up is key

A proper warm up can reduce the chances of injury by up to 40 per cent. But the evidence shows it’s more than just a jog and some stretches.  

“To prevent injuries, a warm-up should have exercise-based elements including a dynamic phase, and an agility and balance phase.

The dynamic phase should include between 6 to 10 active whole-body exercises that get the body warm and moving, for example, hamstring sweeps, open and close gates, and progressive sprints.

The agility phase should replicate the skills and movements you’re going to use when playing, particularly those movements where you are most at risk of injury,” says Mel.  

To prevent ACL injuries, the three main movements to focus on are jumping and landing, particularly on one leg; deceleration or slowing down; and changing direction. 

“If you practice these movements, you get better at them and you prepare your body for what you are about to do,” Mel concludes.  

2. Build regular strengthening exercises into your routine

Along with a proper warm-up, building your strength is important to prevent ACL injuries. 

Traditionally people focus on stretching during cool downs. According to Mel, you actually get more ‘bang for your buck’ in terms of injury prevention by working on your strength. 

“It doesn’t need to be a lot it can be some very simple bodyweight exercises done on the field after training. And it’s a really nice way to cool down as a team,” she says.

The best areas to focus on to prevent ACL injuries are the major muscle groups in your legs, and around the hip and the knee: the quads, the glutes, the hamstrings and calf muscles. 

3. Train like you play 

“In community sport, a lot of people train at a really low intensity,” says Mel. “Then when they get to the game on Saturday they sprint around and play at a much higher intensity, and that’s when most injuries happen.”

“If you sprint on a Saturday, you need to sprint at training. If you tackle on a Saturday, you need to tackle at a training.”

4. Be consistent

A proper warm-up and strength program only work if you do them, says Mel. “We encourage people to do them at every training and every game. They don’t need to take an hour – they can be done in 10 minutes if you use the right program and you practice it.”

5. Find the right injury-prevention program for your sport 

Every field-based sport is different. For example, AFL is a 360-degree sport where you need to tackle, and take contact in the air and on the ground, as such the agility aspects of warm-ups should be tailored to suit your sport.  

You don’t need to reinvent the wheel, says Mel. There are existing warm-ups for every sport, for example, AFLW has the Prep-to-Play program
