2 OBJECTIVES Define kinesiology & explain its importance to the student of human motion. Describe major components of a kinesiology analysis. Describe a selected motor skill; breaking it down into component phases. identifying starting and ending points. Determine simultaneous-sequential nature of movement skills. Classify motor skills. State the mechanical purpose of movement skills 1-2

3 KINESIOLOGY The study of human movement from the point of view of the physical sciences. Mechanics: Biomechanics Anatomy: Musculoskeletal anatomy Physiology: Neuromuscular physiology Every structure that participates in movements of the body does so according to physical and physiological principles. 1-3

4 SAFETY, EFFECTIVENESS & EFFICIENCY The underlying aim of kinesiology is: Safety: structure movements to avoid doing harm to the body. Effectiveness: success or failure of meeting goals of performance. Efficiency: striving to achieve movement goal with least amount of effort. 1-4

5 METHODS OF STUDY CONTROLLED LABORATORY STUDIES Help students gain understanding of the nature & complexity of human motion. Primarily qualitative in beginning. Advanced study include EMG, motion capture, force transducers & computer analysis equipment. As technology advances, new abilities increase the depth of knowledge and understanding. 1-5

6 METHODS OF STUDY ANALYSIS UNDER EVERYDAY CONDITIONS Students learn how to apply a knowledge of kinesiology. Develop qualitative skills necessary for accurate observation, diagnosis, and treatment of faulty motor performance. 1-6

7 COMPONENTS OF ANALYSIS Describing a skill in a logical fashion. Breaking it down into its elements. Determining which elements are critical to SEE principle for performance. Evaluating performance Identifying errors in performance. Identifying the sources of error. Prescribing corrections based on appropriate identification of cause. 1-7

8 KINESIOLOGICAL ANALYSIS (TABLE 1.1) A. Description of the motor skill performance 1. Primary purpose of the skill Applicable references to speed, accuracy, form, etc. speed speed & accuracy accuracy form 1-8

9 KINESIOLOGICAL ANALYSIS (TABLE 1.1) A. Description of the motor skill performance 2. Movement phases break down motion into phases Fig 1.2 preparation power follow through 1-9

10 KINESIOLOGICAL ANALYSIS (TABLE 1.1) A. Description of the motor skill performance 3. Classification of the skill Classification provides clues to the nature of anatomical & mechanical requirements of a group of skills. 1-10

11 KINESIOLOGICAL ANALYSIS A. Description of the motor skill performance 4. Simultaneous-sequential nature of motion Simultaneous segments move as one Sequential segments move in an orderly sequence simultaneous sequential Fig

12 KINESIOLOGICAL ANALYSIS (TABLE 1.1) B. Anatomical analysis 1. Joint actions & segment motions: Joints involved, and exact movements in the skill? Any limited range of motion? Refer to Table Muscle participation & form of contraction: Muscles producing joint actions? Type of contraction? 1-12

13 Anatomical Analysis Model Joint Joint Action Segment Moved Plane & Axis Force Contraction Type Prime Movers 1-13

14 KINESIOLOGICAL ANALYSIS (TABLE 1.1) B. Anatomical analysis 3. Neuromuscular considerations Which neuromuscular mechanisms are involved? What is the nature of involvement? 1-14

15 KINESIOLOGICAL ANALYSIS (TABLE 1.1) B. Anatomical analysis 4. Anatomical principles related to effective & safe performance: Which anatomical principles contribute to efficiency & accuracy? Which principles are related to avoidance of injury? 1-15

16 KINESIOLOGICAL ANALYSIS C. Mechanical analysis 1. Underlying mechanics objective(s) Balance: regain stability, attain mobility Jump stop, track start Locomotion: travel Walking, running, skipping Projection: height, range & accuracy Pole vault, long jump, throwing Manipulation: objects or resistance Weightlifting, writing Maximum effort: speed, power, & force Sprinting, power lift, blocking 1-16

17 C. Mechanical Analysis 2. Nature of the forces causing or impeding motion. Internal forces External forces Modifying forces 3. Identify the critical elements. 4. Mechanical principles that apply Concerning safety. Concerning effectiveness. Concerning efficiency 1-17
