A Study of Kinematic Release Parameters of Male and Female Shot Putters

Today technique is equally the key to better performance, although we cannot escape the facts that "style" will always be an integral aspect in ultimate performance. This is due to the differences in the physical and anatomical structure of the human body, which differs from athlete to athlete.  The aim of the study was to gain understanding of the athlete performance and to communicate the knowledge to the coaches to generate accurate recommendation. The subjects for the study were selected from sports hostel in SAI (Salt Lake City). 05 male and 05 female national athletes were selected randomly and aged from 18 to 28 years. Each of them were given six trials and that best trial result was recorded for the analysis of various parameters. Such as:  height of release, angle of release, speed of release and horizontal release distance.  The above parameters were analyzed and calculated with the help of tracker 4.92 software. The actions of athletes were captured using cannon camera with 120fps speed and parameters like release velocity was calculated. The horizontal distance was calculated by reference tape. Result showed that male and female shot putters did not show any significant difference in angle of release of the shot and horizontal distance gained by the shot at release. The non significance difference in release angle of shot between male and female shot putters is in compliance with the basic mechanical principles

Gastric Duplication in a Preterm Neonate

Background: Gastrointestinal (GI) duplication is defined as a spherical structure with a muscular coat and is lined by a mucous membrane. It is a rare congenital anomaly. Clinical Description: A preterm baby born, delivered at 31 weeks, was diagnosed with respiratory distress syndrome and managed as per hospital protocol. While being weaned off from nasal continuous positive airway pressure, feeding was started. He developed vomiting and epigastric distension within 6 h. Management: The baby was investigated for the cause, and an early-onset sepsis was excluded. X-ray abdomen showed distended stomach and gas shadows in the bowel loops. Ultrasound did not reveal any gastric outlet obstruction, but significant gaseous distension of the stomach prompted us to make a dye study of the upper GI tract, which revealed cystic outpouching of the stomach that communicated with the gastric lumen. Similar findings were seen on computed tomographic scanning. Exploratory laparotomy performed revealed a large cyst communicating with the stomach at the lesser curvature. This was dissected out entirely from the margin of the stomach. Histopathology revealed highly congested cyst wall with an inner lining of gastric epithelium and gastric glands and an outer smooth muscle coat, confirming a gastric duplication cyst. Conclusion: Gastric duplication should be considered as a differential in newborns with feed intolerance, epigastric distension, and significant distension of the stomach. Although serial radiological investigations provide supportive evidence for this condition, the diagnostic confirmation is obtained by gross inspection and histopathology. In view of high risk of malignant transformation, surgical resection of the entire cyst remains the most definitive management
