SUMMARY:The aim of the present research was to analyze the body composition (BC) and the differences in BC among different playing position in professional basketball, handball and futsal players. BC was assessed in 70 professional indoor team sport players. Players were divided in 4 groups depending on the playing position: group 1, point guard, center/wings and defense; group 2, shooting guard/small forward, handed and midfielder; group 3, power forward/center, pivot and forward; and group 4 goalkeeper. Significant differences between playing positions in basketball in body mass (BM), height, proteins, minerals and arms, legs and trunk BM were found. In handball, significant differences between center/wings and pivot in BM and muscle mass, and between goalkeepers and handed in percentage of fat were measured. Significant differences were also found in BM of each playing position groups in the three sports and in arms and legs BM in groups 1 and 2, and trunk BM and height in group 2. Group 3 presented significant differences between futsal and basketball in skeletal muscle mass and trunk BM, and between basketball and handball in left leg BM and total BM. In group 4 significant differences in BM, height and trunk and leg BM between futsal and handball were found. BC in indoor team sports depend on the playing position and the sport discipline, the BC being result of the specific game actions of each playing position.
This document is the updated 2019 revision of the EFSUMB Clinically Safety Statement. A Safety Statement has been published by EFSUMB annually since 1994 by the Safety Committee (ECMUS) of the federation. The text is deliberately brief and gives a concise overview of safety in the use of diagnostic ultrasound.
Ultrasound safety is of particular importance in fetal and neonatal scanning. Fetal tissues are vulnerable and often still developing, the scanning depth may be low, and potential biological effects have been insufficiently investigated. On the other hand, the clinical benefit may be considerable. The perinatal period is probably less vulnerable than the first and second trimesters of pregnancy, and ultrasound is often a safer alternative to other diagnostic imaging modalities. Here we present step-by-step procedures for obtaining clinically relevant images while maintaining ultrasound safety. We briefly discuss the current status of the field of ultrasound safety, with special attention to the safety of novel modalities, safety considerations when ultrasound is employed for research and education, and ultrasound of particularly vulnerable tissues, such as the neonatal lung. This CME is prepared by ECMUS, the safety committee of EFSUMB, with contributions from OB/GYN clinicians with a special interest in ultrasound safety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
