Which of the following terms describes the study of systems

Which of the following terms describes the study of systems in a constant state of motion? statics dynamics kinesiology plyometrics Which of the following is true regarding flexibility? It can be measured by range of motion It is joint specific It is influenced by joint structure and muscle size All of above Which of the following heightens the risk of injury? Too low flexibility Too high flexibility Muscle imbalance between left and right Muscle imbalance between opposite sides of joint I only II only I and II III and IV I, II, III, and IV What term is given to considerations such as the size, shape, and weight of body segments? Cybernetic anthropometric kinematic kinetic Which of the following is not an example of a sagittal plane movement? flexion hyperextension lateral flexion plantar-flexion Which of the following is/are vector quantity(s)? angular velocity angular distance both A and B neither A nor B If two uniplanar vectors are added together and the result is zero, then which of the following is true of the vector quantities They are opposite in magnitude They are equal in direction Both A and B Need more information When suddenly pushed on the right shoulder by a big left-oriented horizontal force, in which plane your trunk will mainly move? Sagittal frontal transverse Need more information Because your trunk movement occur in this plane (the plane you picked in #8), where would you most likely place a camera to capture most of the action? Explain your answer.

Solution

1. Dynamics is the study of systems that are in a state of accelerated or changing motion. Statics is the study of systems in a state of equilibrium (at rest or in a constant state of motion) while Kinematics study the motion of objects withour its cause. So, the correct answer is A.

2. Flexibility is defined as the achievable range of motion at a joint or group of joints without causing injury. So, the correct answer is D.
