This study examines the training effectiveness of airsoft guns that look and operate like real guns. Airsoft guns were developed in Japan in the late 1970s and are now popular for leisure sports and training, especially in countries where gun ownership is permitted. In particular, Taiwan has been promoting airsoft gun games to train citizen soldiers, and military leaders such as the United States have also utilized airsoft guns for live fire combat training and combat troops' live fire training. However, due to strict usage regulations and the perception that it is a toy, it is underutilized in Korea despite being a good training tool. Therefore, this study will prove the effectiveness of airsoft guns and improve the military's combat capabilities through practical training using airsoft guns. In addition, it will improve the negative perception of airsoft guns and foster a new sports industry.

The aim of the present study was to evaluate the possibility of protective effectness of swimming exercise and Gastrodia elata blume oral administration against beta-cell damage in streptozotocin (STZ)-induced diabetes in rats. The animals were divided into five groups: the normal group(n=10), the STZ-induced diabetes group(n=10), the STZ-induced diabetes and moderate-intensity exercise group(n=10), the STZ-induced diabetes Gastrodia elata blume(300 mg/kg) oral administration group(n=10), the STZ-induced diabetes and moderate-intensity exercise and Gastrodia elata blume(300 mg/kg) oral administration group(n=10). Animals in the exercise groups were made to swim moderate swimming exercise protocols once a day for 4 consecutive weeks. Serum glucose concentration and insulin level, superoxide dismutase (SOD) and catalase (CAT) were measured in serum. Swimming exercise and Gastrodia elata blume extract administration has shown anti-diabetic effect probably through decreasing serum glucose and insulin level and increasing antioxidant enzyme activity.
