14. WHR
• Waist – horizontal measure taken directly
above the iliac crest/narrowest of torso
• Hip – legs slightly apart, a horizontal measure
taken at maximal circumference of hip or
proximal thigh, just above the gluteal fold
• Male < 0.75
• Female < 0.85

15. SFT
• Seven sites (common for both male and female)
- Chest
- Midaxillary
- Triceps
- Subscapular
- Abdomen
- Suprailiac
- Thigh

16. SFT - men
• Chest, abdomen and thigh
• Chest, triceps and subscapular
• Body density = 1.10938-0.0008267 (sum of 3
SF)+0.0000016(sum of 3 SF)2 -0.0002574(age)
• % fat = (495/Body density)-450

18. Cardiorespiratory Fitness
• Ability to perform large muscle, dynamic,
moderate-to-high intensity exercise for
prolonged periods
• Depends on functional state of respiratory,
cardiovascular and skeletal muscle systems

19. Maximal oxygen uptake (VO2max)
• VO2max is accepted as criterion measure of CR
fitness
• VO2max = max cardiac output x arterial-venous
oxygen difference
• Open-circuit spirometry is used to measure
VO2max
• Direct measurement of VO2max is not feasible

20. Maximal Vs submaximal exercise testing
• Maximal exercise tests have the disadvantage
of maximal volitional fatigue and might
require medical emergencies
• Commonly rely on submaximal exercise tests
• Aim is to determine HR response and predict?

• Naughton Protocol
• USAFSAM Protocol
• Dukes Protocol

30. Constant Work Rate Protocol
• Treadmill or cycle ergometry exercise maybe used at levels
approximate to subject’s functional activity i.e. 3.0 mph on
treadmill or upto 50 W on a cycle ergometer.
• 6 minutes of continuous exercise.
• Constant work rate test for 5 -10 minutes achieves about 70
– 90% of VO2max achieved during incremental exercise
testing.

32. Arm Ergometry
• Work rate increments of 10 W every 2 -3
minutes with a cranking rate of 50 – 60rpm

33. correlation
• Used for Testing patients with vascular,
orthopaedic or neurologic conditions that
prevent them from doing leg exercise.
• Correlation between arm exercise and leg
exercise
r = 0.37

34. Subjective Ratings & Symptoms
• Rate of percieved exertion (RPE)
• Angina
1. Mild, barely noticeable
2. Moderate, bothersome
3. Moderately Severe, Very uncomfortable
4. Most Severe or Intense pain ever experienced

35. Step test
• Step height
- 30.5 cm (12 inch)
- Rate of 24 steps/min
- After test, immediately sit down and HR is
counted for 1 min.
- Counting must start within 5 seconds

36. Test sequence
• Obtain resting HR & BP before exercise in
exercise posture
• Familiarized with ergometer or treadmill. If
using cycle ergometer 5° knee bend in max Ext
• 2-3 min. warm-up
• Monitor HR at least 2 times during each stage
• BP monitored in last minute of each stage

37. Test sequence
• PRE and additional rating scales
• Client appearance and symptoms
• Terminate when subject reaches 70% HRR or
85% of HRmax
• Cool-down/recovery period (passive/cont.ex)
• Continue physiologic observations for 5 min

38. Test termination criteria
• Onset of angina or angina like symptoms
• Drop in systolic BP > 10 mm Hg from baseline
BP despite an increase in workload
• Excessive rise in BP: SBP > 250 mm Hg or DBP
> 115 mm Hg
• Shortness of breath, wheezing, leg cramps or
claudication

39. Test termination criteria
• Signs of poor perfusion
• Failure of heart rate to increase with increased
exercise intensity
• Noticeable change in heart rhythm
• Subjects requests to stop
• Manifestations of severe fatigue
• Failure of testing equipment

40. Interpretation
• HR
• Heart rate recovery
• Systolic BP
• Diastolic BP
• ST-segment depression
• ST-segment elevation
• Aerobic fitness

41. Heart rate
• Progressive linear increase with exercise
• Each MET increase 10 ± 2 beats

42. Heart rate recovery
• An abnormal slowed HRR is associated with a
poor prognosis
• Decrease ≤ 12 beats/min at 1 min (walking)
• Decrease ≤ 22 beats/min at 2 min (supine)

43. Systolic BP
• Progressive increase in SBP at 10 ± 2 mm
Hg/MET
• Discontinue with SBP values of > 250 mm Hg
• Exertional hypotension (> 10 mm Hg) may
signify myocardial ischemia or LV dysfunction
• Maximal exercise SBP of < 140 mm Hg
suggests a poor prognosis

44. Diastolic BP
• Normal response is no change or decrease in
DBP
• DBP of > 115 mm Hg is considered an
endpoint for exercise testing

45. ST-segment depression
• Common manifestation of exercise induced
myocardial ischemia (Mi)
• Horizontal or downsloping ST-segment
depression is more indicative of Mi
• ≥1 mm of horizontal or downsloping ST
segment at J point extending 60-80 msec
• In recovery true positive

46. ST-segment elevation
• Early repolarization
• Indicate wall-motion abnormalities
• Significant myocardial ischemia and localizes
ischemia to specific area of myocardium

47. Aerobic fitness
• Average values of VO2max is expressed as METs
Men = (57.8-0.445[age])/3.5
Women = (41.2-0.343[age])/3.5
• RPE > 17 (abnormal)

48. Muscular fitness
