Biomechanics in sport incorporates a detailed analysis of sport movements in order to minimise the risk of injury and improve sports performance. Sport and exercise biomechanics encompasses the area of science concerned with the analysis of the mechanics of human movement[1]. It refers to the description, detailed analysis and assessment of human movement during sport activities[2]. Mechanics is a branch of physics that is concerned with the description of motion/movement and how forces create motion/movement. In other words, sport biomechanics is the science of explaining how and why the human body moves in the way that it does. In sport and exercise, that definition is often extended to also consider the interaction between the performer and their equipment and environment. Biomechanics is traditionally divided into the areas of kinematics which is a branch of mechanics that deals with the geometry of the motion of objects, including displacement, velocity, and acceleration, without taking into account the forces that produce the motion while kinetics is the study of the relationships between the force system acting on a body and the changes it produces in body motion[1][3][4]. In terms of this, there are skeletal, muscular and neurological considerations we also need to consider when describing biomechanics[2].( Btw this is not mine own writing do not copyright me)
It refers to protection from offspring (tending) and seeking out the mutual defense obtained from a social group (befriending). Typically, psychology suggests that this has evolved from female responses to stress. In this case, initiating small talks in a waiting room is a way of calming nerves and gaining reassurance by utilizing the social interaction.
Answer: D : Additional Protections for Children Involved as Subjects in Research
Explanation:
The specific department of Health and Human Services (HHS) regulations that apply to research with children are known as Additional Protections for Children Involved as Subjects in Research. It involves regulations that impose responsibilities depending on the possible risk in the research and the extent of the possible benefit to the subject.
