This study aims to investigate the effect of latiissimus dorsi (LD) stretching on thoracic excursion and lung capacity in subjects with a short LD. The study included 20 subjects with a short LD, identified by measuring a range of shoulder flexion of <170 degrees in the LD length test. The subjects were randomly assigned to either the control group or the group with LD stretching applied. The thoracic excursion of the upper and lower parts was measured using a circular tape measure, and the lung capacity was recorded using a Pony FX. The experimental group was measured immediately after stretching, and the control group was measured again after resting for 10 minutes. In the experimental group, the thoracic excursion of the lower parts significantly increased after LD stretching (p<.05). In the control group, there were no significant differences in all dependent variables between before and after 10 minutes of rest. After the intervention, the thoracic excursion of the upper parts and the lung capacity did not differ significantly between the groups. These results suggest that for people with short LD, applying LD stretching is effective at improving the thoracic excursion of the lower part.
