 Aims and background: Exercise-related transient abdominal pain (ETAP) or side stitch is a  well known injury in many sport activities. The purpose of this study was to compare vertical displacement of the body and body angles during running in  people with side stitch and healthy people. Materials and Methods: Twenty six subjects (male students) in  Ferdowsi University of Mashhad were selected through non-probability inconvenient sampling and based on the pain during running, they were divided in to two groups; stitch group and control group (13 subjects with stitch and 13 healthy subjects). After the formation of the marker motion model, vertical displacement and angles of the neck, trunk, hip, knee and ankle in both groups were measured during treadmill running by using Motion Analysis system  and theyvwere compared. To analyze the data, independent t-test was used. Findings: Significant differences in Neck angles (P = 0.04), trunk (P = 0.01) and hip (P = 0.02) were observed between the two groups and these angles were significantly higher in control group than stitch group. But no difference between the two groups was observed at angles of knee and ankle (P>0.05). The results also have shown that vertical displacement in stitch group was significantly higher than control group (P = 0.02). conclusion: Increased vertical displacement of the body and reduced angle of the neck, trunk and hips may be factors affecting the incidence of stitch. Therefore, by modifying these factors in people with stitch, perhaps we can reduce their pain
