Introduction to Kinesiolgy

• Chapter 1

2
Nature of kinesiology

• Study of the human body as a machine for the
  performance of work, based in anatomy, mechanics
  and physiology.
• Reasons to study kinesiology?
• Improve performance, restoration of impaired
  function, compensation for lost function
• It is essential educational experience for
  students of physical education, dance, sport, and
  physical medicine
• Enables these professionals to help their
  students or clients perform with optimum safety,
  effectiveness, efficiency
• Principles are applied to both the body and its
  implements

3
Kinesiological analysis

• Uses
• Provide information for teaching/learning motor
  skills
• Foundation for perfecting/repairing/maintaining
  body function
• Task analysis
• Presenting the skill and identifying important
  components
• Diagnose difficulties, correct errors
• Be aware of possible injuries and their
  prevention
• Components
• Description of performance- breaking it down into
  its elements
• Evaluating performance - determining whether
  how related anatomical mechanical principles
  have been violated
• Prescribing corrections based on appropriate
  identification of cause

4
Description of motor skill

• Purpose speed, accuracy, form
• Phases of Movement separate parts
• Discrete beginning/end vs. continuous/cyclical
• Simultaneous (straight line)
• Sequential (curved path)
• i.e. Long Jump preparatory phase, execution
  phase, flight phase, landing phase
• i.e. Swimming (freestyle arm stroke) catch,
  pull, extension, recovery
• Classification rehabilitation, play,
  performance, learning

5
Evaluating performance

• Anatomical Analysis of a Movement Examine joint
  action, segment motion, muscle participation,
  neuromuscular mechanisms involved.
• Which joints are involved? What are their exact
  movements?
• Which muscles are responsible for joint actions?
  
• What is the nature of the contraction?
• Which neuromuscular mechanisms help and/or hinder
  the action? What is the nature of their
  involvement?
• Which anatomical principles contribute to maximal
  efficiency and accuracy in the performance of the
  motor skill?
• Which principles are directly related to the
  avoidance of injury?
• Mechanical Analysis the body is a machine
  subject to the laws of physics
• What are the underlying objectives of the motion?
