Hamstring Injury Prevention Tips

Hamstring injuries are among the most frustrating setbacks in sport — painful, slow to heal, and notoriously prone to recurrence. For football players in Chirnside Park and Croydon, and runners training around Ringwood and Lilydale, hamstring strains are a genuine season-ender if not taken seriously.

The good news: the majority of hamstring injuries are preventable. With the right combination of strength training, warm-up protocols, and load management, you can significantly reduce your risk.

Why Hamstrings Get Injured

The hamstrings are a group of three muscles at the back of the thigh that work hard during sprinting, kicking, jumping, and rapid deceleration. They’re most vulnerable during high-speed running — particularly when the muscle is working eccentrically (lengthening under load) as your foot strikes the ground ahead of your body.

The most common contributing factors to hamstring injury include:

• Insufficient eccentric (lengthening) strength
• Poor warm-up or inadequate preparation before high-intensity activities
• Rapid increases in sprint volume or intensity
• Muscle fatigue in the later stages of training or competition
• History of previous hamstring injury — the single biggest risk factor

The Most Important Exercise: Nordic Hamstring Curls

If there’s one evidence-based exercise that consistently stands out in hamstring injury prevention research, it’s the Nordic hamstring curl. This eccentric-focused movement has been shown to significantly reduce hamstring injury rates in football players when included consistently in a training program.

How to Perform a Nordic Curl

• Kneel on a padded surface with your feet anchored (a partner holds your ankles, or use a barbell)
• Keeping your hips straight, slowly lower your body forward by straightening your knees — resist the fall as long as possible
• Catch yourself with your hands and return to the starting position
• Begin with low reps (3–5) and progress gradually — this exercise is challenging and should not be introduced at full volume suddenly

Nordic curls should be introduced progressively, particularly in preseason, and are typically not appropriate in the immediate return from a hamstring injury.

Additional Strength Exercises for Hamstring Resilience

A comprehensive hamstring prevention program should include a variety of loading positions and movement patterns:

• Romanian deadlifts: Hip-hinging movement that loads the hamstrings through their full range — an important complement to Nordic curls
• Single-leg Romanian deadlifts: Targets each leg individually and improves pelvic stability and balance
• Hamstring bridge holds (isometric): Lower-load option for activation and endurance
• Leg curl variations: Lying or seated leg curls with controlled eccentric component
• Glute strengthening: Strong glutes reduce compensatory load on the hamstrings during running and cutting movements

Warm-Up Protocols That Actually Work

A proper warm-up raises muscle temperature, increases flexibility, and activates the neuromuscular system before explosive activity. For hamstring injury prevention, an effective warm-up should include:

• 5–10 minutes of progressive aerobic activity (jogging, building to strides)
• Dynamic stretching — leg swings, high knees, butt kicks, walking lunges
• Hip and glute activation — lateral band walks, clamshells, glute bridges
• Progressive sprint build-ups before any maximal effort sprinting

Static stretching alone is insufficient as a warm-up and may temporarily reduce muscle power output if done immediately before sprinting.

Managing Training Load

Many hamstring injuries occur not from a single traumatic event, but from accumulated fatigue and inadequate recovery. Key load management principles include:

• Avoid large spikes in sprint volume — particularly when returning from time off
• Monitor the ratio of high-speed running load week to week
• Ensure adequate recovery between high-intensity sessions
• Don’t ignore tightness or early symptoms — these are warning signs

After a Previous Hamstring Injury

Re-injury risk is highest in athletes who have already strained their hamstring — particularly in the first few months after return to sport. A physiotherapy-guided return-to-sport program should include objective testing of strength and flexibility before unrestricted sprinting is resumed. Rushing back into full training before meeting these criteria is the most common cause of recurrence.

At Adapt Sports Physiotherapy in Chirnside Park, we develop individualised prevention programs based on each athlete’s sport, position, injury history and strength profile — so the program actually addresses their specific risk factors.

Frequently Asked Questions

Do I need to do Nordic curls if I’ve never had a hamstring injury?

Nordic curls are beneficial for prevention even if you’ve never been injured. The evidence is strongest in athletes who sprint regularly — particularly football players. If you’re new to this exercise, begin with low volumes and progress gradually to reduce the risk of soreness or minor strain from the exercise itself. (General information only.)

How often should I do hamstring strengthening?

For prevention purposes, 2–3 sessions per week is a common recommendation. During high-volume training periods, once per week may be sufficient to maintain the training stimulus. Your physiotherapist can advise on the appropriate frequency based on your overall training load. (General information only.)

Can stretching prevent hamstring injuries?

Static stretching alone has not been shown to consistently prevent hamstring injuries. Strength training — particularly eccentric loading — has the strongest evidence. Maintaining good flexibility is still worthwhile, but should not replace strengthening as the primary prevention strategy. (General information only.)

When should I return to sprinting after a hamstring strain?

The decision to return to sprinting should be based on objective criteria — not just the absence of pain. These typically include: adequate hamstring strength relative to the uninjured leg, pain-free range of motion, and the ability to complete progressive running without pain or inhibition. Your physiotherapist can guide this process. (General information only.)

How do I know if my hamstring is tight or injured?

General tightness without pain is common and may respond to stretching and warm-up. Pain — particularly during or after sprinting, stretching, or resisted knee flexion — suggests a strain that warrants assessment. If in doubt, seek a physiotherapy review before continuing high-intensity training. (General information only.)
