Cardiorespiratory Appraisals
Cardiorespiratory Fitness
• Finding Appraisals that Are Right for You
• Consult with your physical education teacher if you
aren’t certain which appraisals are best for you
• Alert your physical education teacher if you have
medical reasons for not participating in the appraisals

Cardiorespiratory Appraisals
What Is Aerobic Fitness?
• Aerobic fitness:
• Refers to the overall efficiency of the heart, lungs,
blood vessels, and exercising muscles
• VO2 MAX
• The amount of oxygen consumption during intense
(“maximal”) effort

Chapter 4-4
Cardiorespiratory Appraisals
What Is Aerobic Fitness?
• Resting Heart Rate (RHR)
• Average of 70 to 80 beats per minute (bpm)
• Finding your pulse:
• Place fingers on the carotid artery (neck) or radial
artery (wrist)
• Count each time over the course of a minute that the
artery “pulses” against your fingers

Cardiorespiratory Appraisals
Target Heart Rate Zone
• To find your Target Heart Rate Zone:
• Find your Heart Rate Reserve (HRR):
• Maximal Heart Rate (MHR) = 220 – your age
• Heart Rate Reserve (HRR) = MHR – RHR
• Then calculate your Target Heart Rate Zone:
• Upper limit = (85 percent of HRR) + RHR
• Lower limit = (50 percent of HRR) + RHR

Musculoskeletal Fitness
• Refers to muscular strength and muscular endurance, as
well as the flexibility of your joints
• Muscular Strength:
• The maximum force a muscle can exert in a single
contraction
• Muscular Endurance:
• A muscle’s ability to perform repeatedly without fatigue
• Flexibility:
• The ability of joints to bend through their full range of
movement (ROM)

• Specifically measures the strength of your forearm
muscles, but a good indicator of overall muscular strength
• Measure both hands alternatively—two trials for each
hand
• Add the two maximum scores for each hand to determine
your hand-grip score

Body Mass Index (BMI)
• Provides a rough indication as to whether your
body weight (mass) is appropriate for your height
• Does not distinguish between body fat and dense
muscle
• Does not take into account where body fat resides
• CPAFLA recommends that this appraisal be
combined with the Waist Circumference appraisal
