## Overview Abdominal strain from jumping refers to injury of the abdominal wall muscles or associated structures that occurs during the high-force loading of takeoff, flight, or landing in jumping sports. The rectus abdominis, external and internal oblique muscles, and supporting fascia can be overstretched or torn when a horse engages its core to lift the forehand, round the back, or absorb landing forces. Mild strains may present as subtle performance changes, while more severe injuries can cause acute pain, reluctance to jump, or secondary issues such as mesenteric rents if internal tissues are involved. ## Causes The primary cause is repetitive or sudden overload during jumping. Poor footing, fatigue, inadequate core conditioning, conformational issues, or a sudden increase in jump height or volume raise risk. Trauma from a fall or awkward landing can also produce strain. In broodmares, abdominal strain during late pregnancy or foaling is a related risk factor that can predispose to mesenteric tears, but jumping-related strain is distinct and more common in sport horses. ## Diagnosis Diagnosis is largely clinical. History of recent jumping combined with reluctance to jump, shortened stride, or pain on palpation of the abdominal wall supports the diagnosis. Ultrasound can identify muscle tears, hematomas, or fascial disruption. Rectal examination and abdominal ultrasound help rule out more serious internal injuries such as mesenteric rents or intestinal entrapment. Differential diagnoses include back pain, sacroiliac dysfunction, and mild colic. ## Treatment Initial management focuses on rest, controlled exercise, and anti-inflammatory medication. Cold therapy and supportive bandaging may help in the acute phase. Gradual return to work under veterinary guidance is essential; premature jumping often leads to reinjury. Severe tears or associated internal injury may require surgical exploration. ## Recovery and Prognosis Most uncomplicated muscle strains heal with 4 to 12 weeks of rest and progressive rehabilitation. Prognosis is good for return to previous level of work if the injury is managed conservatively and the horse is not returned to jumping too soon. Cases involving mesenteric rents or intestinal compromise carry a more guarded prognosis and often require emergency surgery. ## Prevention Progressive conditioning of the core and hindquarters, appropriate footing, and avoidance of sudden increases in jumping demand reduce risk. Regular veterinary and farrier care to address underlying biomechanical issues is also helpful.
