Hamstring Strains in Soccer Players: Understanding, Preventing, and Treating the Injury

Introduction

Hamstring strains are one of the most common injuries faced by soccer players, often resulting from the intense physical demands of the sport. Whether you're sprinting down the field, quickly changing direction, or going for a powerful kick, your hamstrings play a crucial role in these movements. Unfortunately, they are also vulnerable to strains, which can sideline players for weeks or months. In this blog post, we'll explore what hamstring strains are, why they occur, how to treat them, and most importantly, how to prevent them.

What is a Hamstring Strain?

The hamstrings are a group of three muscles located at the back of your thigh. These muscles work together to bend the knee and extend the hip, making them essential for running, jumping, and kicking—the core activities in soccer. A hamstring strain occurs when one or more of these muscles are overstretched or torn. Strains range from mild (a small or overstretch) to severe (a complete muscle tear).

Causes of Hamstring Strains in Soccer Players

• Sudden Acceleration or Deceleration: Sprinting and sudden stops are common in soccer and can place significant stress on the hamstrings, especially when they aren’t properly warmed up.

• Overuse: Repetitive movements and continuous running without adequate rest can lead to muscle fatigue, increasing the likelihood of a strain.  Understanding workload management is critical when training at high levels.  A simple rule for youth is to keep weekly training hours, equal to or less than their age. For example: An 8-year-old should not train more than 8 hours per week.

• Muscle Imbalance: If the quadriceps (the muscles at the front of the thigh) are significantly stronger than the hamstrings, this imbalance can place excessive strain on the hamstrings during movement.  Additionally, training each limb separately will help to isolate each muscle group and prevent muscle imbalances between your left and right hamstrings and quads.

• Inadequate Warm-Up: Starting intense physical activity without a proper warm-up can leave the hamstrings tight and less flexible, making them more susceptible to injury.

• Previous Injury: Players who have had a previous hamstring strain are at a higher risk of re-injury, particularly if the previous injury wasn’t fully rehabilitated.

Symptoms of a Hamstring Strain

• Sudden, Sharp Pain: Typically felt at the back of the thigh during activity, often accompanied by a "popping" or "tearing" sensation.

• Swelling and Bruising: The injured area may become swollen, and bruising can appear, especially with more severe strains.

• Muscle Weakness: Difficulty in bending the knee or straightening the leg fully.

• Tenderness: The back of the thigh may be tender to touch, and moving the leg may be painful.

Treatment for Hamstring Strains

1. Immediate Rest

• Stop Playing: As soon as you feel pain or suspect a hamstring strain, stop playing or training immediately to prevent further injury.

• Avoid Specific Activities: Rest the muscles and avoid activities that cause pain in the hamstring.

2. Ice the Injury

• Apply Ice: Use an ice pack on the injured area for 15-20 minutes every 1-2 hours during the first 48 hours. This helps reduce swelling and numb the pain.

• Use a Barrier: Always place a cloth or towel between the ice pack and your skin to avoid frostbite.

3. Compression & Tape

• Wrap the Area: Use an elastic bandage to compress the hamstring. This can help reduce swelling and provide support to the muscle.

• KT Tape: Once you stop using the compression bandage, apply KT Tape to your hamstrings for 1-4 days to reduce the amount of tension in your weakened hamstrings as you begin to move around.

5. Rehabilitation

• Physical Therapy: Once the initial pain and swelling subside, a physical therapist can guide you through exercises to restore strength and flexibility to the hamstring.

• Strengthening Exercises: Gradual strengthening exercises are essential for rebuilding the muscle and preventing re-injury. Start with isometric exercises without causing pain and slowly progress to body-weighted strength training. The last type of strength training is eccentric contractions of the hamstring such as Nordic hamstrings.

• Rolling out and Stretching: Start by rolling out your injured hamstring for the first couple of days, depending on the severity of your hamstring strain. Next, begin gentle stretching exercises to help restore flexibility as the muscle heals.

6. Gradual Return to Activity

• Take Your Time: Returning to full activity too soon can lead to re-injury. Gradually increase your activity level as the hamstring heals.  A progression of activity starts with walking without pain, going up and down stairs without pain, then increasing the walking to 1 mile.  Once you can tolerate this, begin jogging.  After you can jog for 1.5 miles without pain, begin training at 50% capacity.  This means when you return to play, train the first few sessions for 45 minutes of a 1.5-hour practice session without pain.  At this time, avoid top-end sprints, shooting, and goal or corner kicks.  If you can tolerate this without any pain or residual symptoms in your hamstring, you can start increasing the duration of your training or the intensity.  Once you start increasing the intensity of your training, decrease the duration for a session or two.  If you need help with this progression book your session below.

• Use of KT Tape: Apply KT Tape during training to alleviate strain on your hamstrings as you return to play and continue to strengthen your hamstrings.

• Listen to Your Body: If you feel pain or discomfort during rehabilitation, stop and consult with your physical therapist or doctor.

Preventing Hamstring Strains

• Proper Warm-Up: Always start with a proper dynamic warm-up before playing or training. A good warm-up increases blood flow to the muscles and prepares them for the demands of soccer.

• Strength Training: Regularly strengthen your hamstrings and quadriceps to maintain muscle balance and reduce the risk of injury.  Body-weighted strength training for children is recommended before puberty.  Muscle endurance strength training is a great option by, decreasing the weight and increasing the reps and sets.  

• Improve Flexibility: Incorporate stretching into your routine to keep your hamstrings flexible and less prone to strains. Static stretching at the end of each training is highly recommended.

• Stay Hydrated: Dehydration can lead to muscle fatigue and cramps, which increases the risk of strains.

• Cooldown: After playing, a proper cooldown with light jogging and stretching can help relax the muscles and reduce stiffness.

Conclusion

Hamstring strains are a common and frustrating injury for soccer players, but with proper care and attention, they can be managed effectively. By understanding the causes and symptoms of hamstring strains, and by taking steps to prevent them, you can keep yourself on the field and performing at your best. If you do experience a hamstring strain, remember that rest and gradual rehabilitation are key to a full recovery. With the right approach, you can return to play stronger and more resilient than before.
