Anatomical Kinesiology:  General Study Mechanics WorkSheet.
Professor: Dr. Leo D’Acquisto

1. Define kinesiology and associated subdisciplines.  Why is it important for the physical educator, coach and athlete to understand the basic mechanics of movement.

2. Define biomechanics, kinematics, kinetics, dynamic and static mechanics.

3.  Describe the various components of the  “movement model”.  Discuss how resistance impacts  movement and provide examples of resistive forces (both external and internal forces).  How would you define sustainable power output?  What is efficiency and economy?  How is technique related to resistance to movement and to efficiency and economy of movement.

4.  What is reciprocal innervation and inhibition?  What does high and low contraction mean, and how are both related to efficiency of executing a motor task.

5.  Review motion in space. Consider the planes and axes that the body moves in and around. List the different planes and axes. Provide examples of movements in the various planes and associated axes.

6.  What is general motion? In your answer provide insight into translatory and rotatory or angular movement. Provide examples of general motion. What is the difference between linear motion (also called rectilinear motion), curvilinear and circular motion?

7.  Distinguish between a vector and a scalar quantity. Give examples of each. Refer to your handout on Vector and Scalar quantities.  Utilize vectors to illustrate drag and lift forces on a swimmer’s hand.  From a mechanical perspective, muscle serves to (1) rotate a limb, and (2) stabilize the joint in question.  Illustrate the following schematically:  rotatory and stabilizing force vectors, resultant muscle force vector, line of muscular pull, and mechanical axis.

8. Use vectors to follow the path of a long jumper’s velocity (as measured at the center of gravity) during an actual jump. Illustrate the vertical, horizontal and resultant velocity vectors.

9.  What is the difference between linear and angular velocity, speed, linear and angular acceleration?
 
10. What is gravity?  What does the center of gravity represent?  When standing in the anatomical position, where is the center of gravity located?



11.  Define a movement cycle of a particular task (i.e., running, swimming, free throw; you pick).  Identify the various phases of the movement cycle (pp. 136-138 will provide some general hints).

12.  Define the following: speed, velocity, acceleration.  Refer to your Kinematic Laboratory assignment for additional information and calculations of velocity and acceleration.

13.  Utilize vectors to map out the horizontal, vertical, and resultant velocity of the center of gravity for a high jumper, shot put, and long jumper.

14.  In considering most general movement patterns such as walking, running, swimming, is the application of propulsive force throughout a movement cycle constant?  Yes/No, explain?

15.  What is a projectile?

16. Illustrate the influence of gravity on the center of gravity for a javelin moving through space.

17. What factors dictate the trajectory of a projectile.

18.  What is energy, work, power, kinetic energy and potential energy? Describe the stair run test.  What does it measure and what calculations are involved (provide and example).  Refer to your Energy, Work and Power Laboratory handout.

19.  Differentiate between a general movement pattern, skill and technique?  Check out pp. 160 & 161 for a review of general movement patterns (noted as general skills) and specific skills.  Distinguish between non repetitive, repetitive, closed and open skills (pp. 132 & 133).

20.  Review and understand summary points on pp. 28-29.
