And How to Best Prevent Them

Right, Lets Talk About Staying on the Pitch

Look, I am going to be real with you from the off. I have had a herniated disc, osteitis pubis, rotator cuff tears, back spasms that wiped me out twice in one season. I know what it feels like to be limping into championship week wondering if you are going to make it. And I know what it feels like to have done the work, stayed healthy, and performed. The difference between those two versions of me was what I did away from match day.

The thing is, you cant bulletproof yourself. I say that all the time and I mean it. No exercise, no plan, no physio is going to give you a 100% guarantee. But what you can do is stack the odds in your favour. And for most club players, the lads who end up injured are not unlucky. They are under-prepared, under-recovered, or just doing too much of the wrong things at the wrong times of year.

This guide breaks down the most common GAA injuries, why they happen, and what you can actually do to reduce the risk. Not theory. Practical stuff you can apply to your own training this week.

The Big Picture: What Are GAA Players Dealing With?

Before we get into each injury, heres a quick summary of the main ones, how common they are, and roughly how long they take you out for. Take a look at this and if something jumps out at you, go straight to that section.

1. Hamstring Strains

Why Hamstrings Are GAA's Number One Problem

Hamstrings are the most common injury in GAA. Full stop. An 8-year study across 15 elite Gaelic football teams found that hamstring injuries accounted for 21% of all injuries, and each team was averaging 9 hamstring injuries per season (Opar et al., 2012; PubMed 2016). That is a staggering number when you think about it.

And what makes it worse is the recurrence rate. Once you pull your hamstring, you are 3.3 times more likely to do it again compared to a lad who has never had one (Roe, 2023). The first 8 weeks back are the most dangerous window. You feel grand at training, you push it in a match, and bang, its gone again.

Why Does It Happen?

Hamstring injuries happen almost exclusively during sprinting, specifically at the point of maximum velocity where the hamstring is working eccentrically to decelerate the lower leg. The bicep femoris is the most commonly affected part, making up about 44% of all hamstring injuries (PubMed, 2016).

The main risk factors are:

• Previous hamstring injury (biggest single predictor)

• Low eccentric hamstring strength

• Not enough exposure to high-speed running in training

• Poor hip extension strength and core control

• Jumping too hard too fast when returning from time off

Prevention: What Actually Works

Nordic Hamstring Curls are probably the single most evidence-backed exercise for reducing hamstring injuries. A systematic review and meta-analysis found that injury prevention programs including Nordic curls halved the rate of hamstring injuries across 8,459 athletes (PubMed, 2019). Half. That is not a small number.

How to do them: Kneel on a soft surface with a partner holding your ankles. Keep your body straight from shoulders to knees. Slowly lean forward as far as you can, resisting the fall with your hamstrings. When you can no longer hold it, use your hands to catch yourself. Start with 3 to 5 reps and build from there.

Beyond Nordics, the other big one is this: sprint regularly. I know that sounds obvious but a lot of lads are only sprinting at full intensity in matches. You need to be doing it in training too. Micro-dose speed work before your club sessions. Three 10-metre accelerations, three 20-metre runs, three 40-metre efforts. One minute rest per 10 metres covered. Low volume, high quality. That is enough to keep the hamstrings conditioned for match demands.

Summary of prevention:

• Nordic hamstring curls 2 to 3 times per week in the off-season, 1 to 2 times in-season

• Regular exposure to high-speed running, even small doses before training

• Hip hinge strength work: Romanian deadlifts, single-leg deadlifts

• Proper warm-up before training and matches

• Smart return-to-play after any hamstring injury, do not rush the first 8 weeks back

2. Groin / Adductor Injuries

The Quiet One That Lingers

Groin injuries are the ones that never seem to fully go away. You tweak it kicking a ball, it feels fine after a few days, you get back training, and then it flares up again three weeks later. Sound familiar? That is the nature of adductor injuries and they are incredibly common in GAA because of the demands of kicking, lateral movement, and rapid changes of direction.

Groin injuries account for around 18% of all football injuries (Mosler et al., 2018), and the recurrence rate is 21.5%, which tells you exactly why so many lads are carrying them for months at a time (Rebalance Physiotherapy, 2024).

Why Does It Happen?

The groin is under serious load every time you kick a ball, change direction at pace, or push off laterally. The adductor muscles on the inside of your thigh are the primary movers and they are particularly vulnerable when they are being stretched at speed or when there is a sudden, powerful contraction like a long kick.

Key risk factors:

• Previous groin injury

• Weak adductors relative to hip abductors

• Low hip mobility

• Sudden increase in kicking volume (start of pre-season is notorious for this)

• Inadequate warm-up before sessions

Prevention: Build the Adductors Up Properly

The Copenhagen adductor exercise is the groin equivalent of the Nordic hamstring curl. It is an eccentric adductor exercise that has strong research support for reducing groin injuries. You need a bench or partner. Lie on your side, top leg on the bench or held by your partner, bottom leg hanging. Lower your hip to the ground and use your adductor to drive it back up. Start with small ranges and build over weeks.

Other important work:

• Hip mobility work: deep squats, lateral lunges, hip circles

• Adductor squeezes with a medicine ball between knees during compound lifts

• Single-leg work: split squats, Bulgarian split squats

• Build kicking volume gradually, especially at the start of pre-season

3. Ankle Sprains

The One Everyone Ignores and Regrets

Ankle sprains are one of those injuries that get dismissed. You roll it, it is a bit sore for a few days, you tape it up and get back out. But if you do not rehab it properly, you are setting yourself up for a chronic problem. Individuals who suffer a lateral ankle sprain have double the re-injury risk in the year after the initial injury (Verhagen et al., 2005).

The recurrence rate for ankle injuries in GAA is 13.5% (Rebalance Physiotherapy, 2024). That is a lot of lads going back to the physio with the same ankle. Most of the time it is because they never did the rehab properly the first time round.

Why Does It Happen?

Ankle sprains happen when the foot rolls inward or outward beyond its normal range, usually during:

• Landing from a jump awkwardly

• Quick direction changes

• Uneven ground (county pitches are not all perfect)

• Physical contact that knocks your foot underneath you

Once you have sprained an ankle, the proprioceptive receptors (the nerves that tell your brain where your foot is in space) can be damaged. If you do not retrain them, your ankle is less stable and more likely to go again.

Prevention: Balance Work and Ankle Strength

This is where proprioception training comes in. Single-leg balance work is cheap, takes no equipment, and is genuinely effective. Doing something as simple as standing on one leg while brushing your teeth every morning starts to retrain those receptors.

More structured work:

• Single-leg deadlifts: strength and balance combined

• Single-leg calf raises: eccentric focus, lower slowly

• Balance board or wobble board work

• Plyometric work: box jumps, broad jumps, working on landing mechanics

• Ankle stiffness drills: pogo jumps, ankle circles

4. Knee Injuries (ACL / MCL)

The One Nobody Wants

ACL injuries are not the most common injury in GAA but they are the most devastating. A full ACL tear means surgery, 9 to 12 months of rehab, and the mental battle of trying to get back to where you were. The emotional toll of an ACL is something a lot of lads do not talk about but it is real.

MCL injuries are more common and less severe but they still take you out for weeks at a time if not managed properly. Both injuries often happen in non-contact situations, cutting at pace or landing from a jump with poor knee control.

Why Does It Happen?

ACL and MCL injuries typically involve:

• Poor knee mechanics during cutting or landing (knee caving inward)

• Weak glutes and hip stabilisers

• Poor hamstring-to-quadriceps strength ratio

• Reactive scenarios where the body is not ready for the demand

The biggest modifiable risk factors are neuromuscular control and strength imbalances. If your glutes are weak and your quads are dominant, your knee is in a much more vulnerable position during explosive movements.

Prevention: Build From the Ground Up

Prevention of ACL injuries comes down to training the body to handle force better across all planes. The key areas are:

• Unilateral lower limb strengthening: single-leg squats, Bulgarian split squats, step-ups

• Glute strength: hip thrusts, lateral band walks (with purpose, not as a gimmick), Romanian deadlifts

• Landing mechanics: learn to land soft, bend the knees, push the hips back

• Plyometrics: teach the body to load and unload correctly under speed

• Nordic hamstring curls: also protect the ACL by improving the hamstring-to-quad ratio

5. Lower Back Issues

The Injury Nobody Talks About Enough

I will be honest here because I have been through it twice. Back spasms that put me out in the lead-up to championship games. And before that, a herniated disc that caused sciatic nerve issues down my leg. Lower back problems are incredibly common in GAA players, especially ones who are doing a lot of gym work and a lot of running without addressing mobility and posterior chain strength properly.

The back is often the symptom, not the problem. A lot of lower back issues in GAA players come from tight hip flexors, weak glutes, poor core stability, or compensating for another injury elsewhere in the body. Fix those things and the back often sorts itself out.

Why Does It Happen?

• Sedentary lifestyle between training (sitting at a desk all day, then going to train)

• Weak glutes forcing the lower back to compensate

• Tight hip flexors pulling the pelvis forward (anterior pelvic tilt)

• Rapid spikes in training load without adequate preparation

• Poor lifting technique in the gym, particularly on heavy compound movements

Prevention: The Posterior Chain and Mobility Are Your Friends

The off-season is the time to really get after this. Building a strong posterior chain, glutes, hamstrings, lower back itself, is the foundation. But it needs to be paired with mobility work to actually make a difference.

Key work:

• Hip hinge pattern: Romanian deadlifts, good mornings, kettlebell swings

• Glute activation: hip thrusts, glute bridges, single-leg variations

• Core stability: dead bugs, pallof press, planks (not just crunches)

• Hip flexor mobility: 90/90 stretches, couch stretch, hip circles

• Thoracic mobility: cat-cows, foam roller extensions

The Big Picture: Injury Prevention Is Not One Thing

Here is something David Gray (David Gray Rehab) said on the podcast that stuck with me. Injuries are very individual. You can be doing the same training as the lad beside you and he is flying it while you are on the physio table. That is not bad luck most of the time. It is years of preparation, or the lack of it.

The best thing you can do for your long-term injury prevention is not any one exercise or program. It is the accumulation of good habits over time:

• Consistent gym work all year round, not just before pre-season

• Proper sleep and nutrition to support recovery

• Regular exposure to high-speed running so your body is conditioned for match demands

• Not panicking and jumping from zero to 100 at the start of every pre-season

• Actually doing your rehab properly when you do get injured, not rushing back

• Playing lots of different sports when you are young, developing broad athletic qualities

Previous injury is the single biggest predictor of future injury (Roe, 2023). That is the research. Which means if you have had a hamstring, a groin, or an ankle before, those areas need more attention from you, not less, when you are fit again.
