What is an Abdominal Side Strain?

Cricket fast bowlers and javelin throwers often develop an abdominal side strain. This injury usually involves a tear of the internal oblique muscle where it attaches to one of the lower four ribs or costal cartilages. You will feel sharp pain along the side of the trunk, especially when you bowl, throw, cough or sneeze. If your symptoms include rib pain or difficulty rotating your trunk, you may also want to read about rib stress injuries and costochondritis, which can occasionally present in a similar area.

MRI scans are very useful to confirm the site and severity of the muscle tear. They can also show less common bony stress lesions at the rib attachment. Your physiotherapist or sports doctor will combine your injury history, examination and imaging findings to plan your recovery. For more detail about scan findings, see our guide on muscle strain diagnosis.

Side strain has a strong link with bowling or throwing speed. The fastest bowlers and biggest throwers place the highest load on their abdominal muscles and are therefore at higher risk of injury. This mirrors other high-speed trunk injuries such as lumbar stress injuries in fast bowlers and rotator cuff overload in throwing athletes.

What Causes Side Strain?

Researchers propose that side strain injury results from a sudden eccentric contraction that overloads and tears the internal oblique muscle fibres. During bowling and throwing the muscle is lengthening while it works hard to control trunk rotation. This combination of lengthening and high force creates a powerful eccentric strain. Learn more about similar mechanisms in our overview of throwing injuries.

In fast bowlers the muscle tear usually occurs on the non-bowling arm side. For a right-handed bowler, the left arm lifts high above the body and then pulls down forcefully to drive the bowling arm over. At full stretch the internal oblique on the left side sits at maximum tension. The sudden pull-through to release the ball can then rupture the muscle fibres at their rib attachment. Other throwing sports place the trunk under similar stress. Poor trunk control and fatigue can also contribute, as discussed in Cricket Injuries and core stability recommendations.

How is Side Strain Diagnosed?

Your physiotherapist or sports doctor will ask about your sport, workload and the moment your pain started. They will palpate the painful area, test your trunk movement and assess your bowling or throwing technique. Sometimes symptoms overlap with thoracic or rib injuries, so your clinician may also screen for thoracic spine pain or back muscle strain.

MRI is very sensitive for side strain and usually shows the exact site and depth of the muscular tear. In some cases the muscle can partially avulse from the rib or costal cartilage, strip the periosteum and cause significant bleeding even when the tear looks small. High-speed rotational sports such as baseball, cricket and javelin throwing often show this pattern of injury. You can read more about load-related injuries in our guide to soft tissue tears.

How to Prevent Side Strain

Good preparation lowers your risk of side strain. Warming up properly before bowling or throwing, including some light trunk rotation and side-flexion movements, is very important. Keep your torso warm between spells, especially in cooler weather.

Progressive core and trunk strengthening, load management across the cricket season, and gradual increases in bowling workload are also helpful strategies. Your physiotherapist can design a program that balances strength, flexibility and bowling volume.

Side Strain Treatment

It is crucial to stop bowling or throwing as soon as you feel a sharp side pain. Trying to “bowl through it” often worsens the tear and prolongs your recovery. Apply ice to the painful area in the first 24–48 hours and avoid motions that reproduce your pain.

Most side strains require four to six weeks of staged rehabilitation before a safe return to sport. Treatment usually includes pain relief, gentle mobility work, progressive trunk strengthening and a graded return-to-bowling program. Your physiotherapist will also check for any contributing technique or workload issues.

For the best result and a quicker, safer return to play, book an assessment with a physiotherapist who regularly manages cricket and throwing injuries.
