Hamstring Strain

Explanation of Diagnosis

A hamstring strain is an injury to one of the muscles at the back of your thigh (most often the muscle-tendon unit that helps bend the knee and extend the hip). It usually happens when the hamstring is suddenly stretched and contracting at the same time, such as during sprinting, kicking, or accelerating from a stop. Symptoms commonly include pain, tenderness, stiffness, and sometimes bruising or weakness, especially when you try to run, squat, or push off. Many strains improve with time, relative rest, and a structured return to activity.

Specific Work Modifications

• Switch between sitting, standing, and light walking every 20 to 30 minutes to avoid prolonged hamstring loading.
• Use a chair that lets you keep your thighs supported and your hips from repeatedly collapsing forward.
• When lifting, keep loads close to your body and avoid bending deep from the back with straight knees.
• Take brief “micro-breaks” (2 to 3 minutes) to gently move through comfortable hip and knee positions rather than forcing stretching.
• If stairs or hills aggravate symptoms, use slower pace and shorter steps, and consider taking an alternate route temporarily.

Specific Activity Modifications

• Avoid sprinting, jumping, and fast directional changes until symptoms consistently settle.
• Pause or reduce activities that require aggressive hamstring stretching under load, such as deep forward bends with straight legs.
• Temporarily avoid heavy running, hill workouts, and high-resistance hip hinge or deadlift variations.
• Choose low-impact options like stationary biking (gentle range), comfortable walking, or swimming kick adjustments that do not increase pain.
• When you return, progress gradually and stop the session if you feel a sharp “twinge,” increased tightness, or a loss of normal control.

Recommended Supplements

• Omega-3 fish oil (about 1,000 to 2,000 mg per day combined EPA and DHA with food) may help support a balanced inflammatory response.
• Curcumin (about 500 mg 1 to 2 times per day with meals) may help with symptom control in some people with musculoskeletal injuries.
• Collagen peptides (about 10 g daily) may support tissue building when paired with rehab and adequate protein intake.

Recommended Nutrition and Hydration

Diet Recommendations

• Aim for protein at each meal (examples include eggs, yogurt, fish, chicken, beans, or tofu) to support tissue repair.
• Eat a variety of colorful fruits and vegetables daily to provide antioxidants and micronutrients involved in recovery.
• Choose mostly whole grains, nuts, olive oil, and other minimally processed foods to support overall healing.
• Avoid heavy alcohol intake and be cautious with very restrictive diets while you’re rehabbing.

Hydration Tips

• Drink regularly through the day, using pale-yellow urine as a practical guide.
• Have an extra glass of water around exercise days, especially if you’re sweating or in warm environments.

Home Exercise Prescription

Perform these exercises about 3 to 4 days per week, and only progress when they remain clearly pain-free or only mildly uncomfortable during the activity and not worse afterward.

1. Heel slides: Lie on your back and slowly slide your heel toward your buttocks within a comfortable range, then return; do 2 sets of 8 to 12 reps.
2. Glute bridge: With knees bent, lift your hips until you feel comfortable tension through the front of the hips and back of the thighs, then lower slowly; do 2 sets of 8 to 12 reps.
3. Prone hamstring isometric: Lie on your stomach with a rolled towel under the painful knee area; gently press the knee into the towel to create a mild hamstring contraction without moving the leg much, then relax; hold 20 to 30 seconds, repeat 5 times.
4. Standing hip extension (knee slightly bent): Hold a counter for support and move your leg backward a small, controlled amount without arching your back; do 2 sets of 8 to 12 reps each side.
5. Supported mini-hinge: Stand holding a counter, gently shift your hips back slightly while keeping a neutral spine, then return; do 2 sets of 6 to 10 reps.
