3 ANTHRPOMETRY ANTHRO. HUMAN METREIN. MEASURE THUS, ANTHROPOMETRY DEALS WITH MEASURE OF HUMANKIND

5 SIZE IS IMPORTANT IT DOES MATTER

9 ANTHROPOMETRY IS SIZE THE MEASURE OF HUMAN? WE ALL HAVE HEARD SIZE IS NO MEASURE OF MAN (HUMAN) BUT, IS SIZE THE ONLY MEASURE OF WORKING HUMAN? PROBABLY NOT!

10 ANTHROPOMETRY SIZE IS ONE OF MANY VARIABLE OF ANY WORKING HUMAN SIZE IS UNIQUE TO THE INDIVIDUAL INDIVIDUALS VARY COLLECTION OF VARIABLES CHARACTERIZES A WORKING INDIVIDUAL MORE MEANINGFULLY AND REFLECTS THEIR PHYSICALLY FUNCTIONING INDIVIDUALITY

11 PERFORMANCE IS A RESULT OF INTEGRATED EFFORT OF: PHYSICAL FACTORS COGNITIVE FACTORS PSYCHOSOCIAL FACTORS CULTURAL FACTORS (SOMETIMES)

12 PHYSICAL FACTORS FUNCTIONAL STRENGTH SPEED RANGE OF MOTION ENDURANCE AEROBIC CAPACITY PRECISION DEXTERITY etc. STRUCTURAL BODY SIZE MOMENT ARM MUSCLE CSA JOB & BODY CONFIGURATION FLEXIBILITY CONDITIONING

13 STRENGTH. For example IN THE CASE OF LIFTING STRENGTH

14 ILO : Men 24 kg Women 21kg STANDARDS NIOSH: Action Limit 3400 N Lumbosacral compression 3.5 Kcal/min Energy cost Acceptable to 99% males and 75% females Epidemiological risk of injury low

16 o Isokinetic and Isometric (with hip at 90 ) stoop-lift strength (Males)

17 o Isokinetic and Isometric (with knee at 90 ) squat-lift strength (Males)

18 Functional Strength Measure Strength in Newtons (N) Required 300 Available

20 Range of Motion (degrees) Required Available 30 0

21 Flexion Adduction DEFICIT AVAILABLE Abduction Extension

22 Flexion Adduction DEFICIT AVAILABLE Abduction Extension

23 Flexion External Rotation Internal Rotation Adduction DEFICIT AVAILABLE Abduction Extension

25 Range of Motion (degrees) Required 30 Available Strength in Newtons

26 Strength ROM Speed

27 AEROBIC CAPACITY & ENDURANCE

31 Physical Profile SP-STR-ROM END-AC DEX-PRE

32 LOAD (Logarithmic Scale) A D MOTION B (Logarithmic Scale) C EXPOSURE TIME (Logarithmic Scale)

33 Model of Safety and Hazard MOS + JMR = 1 Therefore, MOS = 1 - JMR

34 A composite index (C1) of JMR can be obtained by its: three risk factors (R 1, R 2, R 3 ) corresponding safety (S 1, S 2, S 3 )

35 Therefore, MOS = S 1 x S 2 x S 3 = (1 - R 1 ) (1 - R 2 ) (1 - R 3 ) Since, Risk = 1 - Safety Therefore in simple conceptual terms, CI = [1 - (1 - R 1 ) (1 - R 2 ) (1 - R 3 )]

37 COGNITIVE

38 Psychological Profile PER-REAC.TM COG-JD DEC.MK-OPER

39 PSYCHOSOCIAL

40 Social Profile TSK.ACC. & COM DR., MOT SLF.EST, CON

41 Composite Performance Capacity Physical Social Psychological

42 Speed Dexterity Strength Precision Range of Motion Physical Performance Factors Endurance Pain Tissue Tolerance Aerobic Capacity Cardio Vascular Fitness

43 Integrative Judgment Decision Making Reaction Time Cognition Operation Perception Peer-acceptance Self-esteem Psycho-social Performance Factors Confidence Goal orientation Drive Fatigue Motivation Task commitment

44 Tissue Pain Tolerance Aerobic Capacity Endurance Precision Dexterity Speed A Perception Cognition B Integrative Judgment Decision Making Reaction Time Operation Fatigue Motivation Strength ROM of Motion Task Drive Esteem Commitment Goal Confidence Orientation Peer Acceptance Self

45 Tissue Pain Tolerance Aerobic Capacity Endurance Precision Dexterity Speed A Perception Cognition B Integrative Judgment Decision Making Reaction Time Operation Fatigue Motivation Strength ROM of Motion Task Drive Esteem Commitment Goal Confidence Orientation Peer Acceptance Self

46 SIZE ANTHROPOMETRY MAY INCLUDE: STRENGTH (Range and optimal values) RANGE OF MOTION (Optimal range) RANGE OF SPEEDS (Optimal speed)
