Benefits of fitness assessments
1. Establish current health status
2. Gauges progress and comparison
3. To educate and involve clients
4. Demonstrates prudence and knowledge
Six components of fitness assessment
1. Assess resting heart rate & blood pressure
2. Assess body composition( skin fold and waist-to-hip ratio )
3. Assess cardiorespiratory fitness ( 3-minute step test or Rockport Walking Test)
4. Assess muscular strength and or endurance(push-up test and partial curl up test).
5. Assess flexibility ( e.g. Sit and reach test) and posture.
6. Optional fitness assessment components.
Which test(s) may only be performed by a licensed health care professional in some states?
Measuring blood pressure
The current blood pressure value for hypertension
> or equal to 140/90
The current blood pressure value for normal
5 cardiorespiratory tests and indicate whether they are max or sub
1. Stress Test-Max
2. 3 Minute Step test-Sub
4. Field Test-Max
5. Rockport 1 Mile Walking Test-Sub
Importance of body fat percent (%) testing
To educate your client about the risk of too much body fat...diabetes, CHD, high bp, cancers, low back pain
Methods of estimating body fat
4. Near-infrared interactance
5. Bioelectric impedance analysis
6. Skin fold caliper analysis
Percent of body fat for a heathy man
Percent of body fat for a heathy woman
Protocols for skin fold testing
>All measurement should be made on the right side of the body with the subject standing upright
>The Caliper should be placed directly on the skin surface, 1cm away from the thumb and finger, perpendicular to the skin-fold and half way btwn the crest and the base of the fold.
>Pinch should be maintained while reading the caliper.
> Wait 1-2 seconds (not longer) before reading caliper.
>Take duplicate measurements at each site and retest if duplicate are not within 1-2 mm.
> Rotate through measurement sites or allow time for skin to regain normal texture and thickness.
> Meticulously identify the site using anatomical landmarks
Purpose and goals of cardiovascular testing
Diagnose and assess levels of fitness
Submaximal exercise tests
1. The three minute step test
2. The Rockport walking test
3. The Rockport treadmill test
Advantages of submax cv testing
Less expensive. Less risky since the test ends at or before 85% of the heart rate reserve. Less space required
Skin fold testing in males should be measured at the
Chest, abs, thigh
Skin fold testing in females should be measured at the
Triceps, suprailiac, thigh
Protocols of the 3 min YMCA step test
1. Describe the procedure and ask that your client refrain from talking or laughing to maintain heart rate.
2. Set heart rate at 96 bpm and when the client begins stepping start your timer. The exercise must be done on a 12 inch bench. Have him step for 3mins letting him/her know when a minute has passed.
3. When 3 minutes are up tell client to sit down. Within five sec measure the recovery hr. Count for one min.
4.Use the minute value for the recovery hr and consult the norms for your clients age and sex
Muscle or muscles groups ability to sustain repetitive contractions over a period of time
Protocols for 1 rm test.
1. Have client stretch
2.Start with weight that can be comfortably lifted then progressively add weights until weight can be lifted with proper form just one time. Allow client to rest 3-four mins btwn trials.
3. After finding the 1 rm for the bench press, divide the 1 rm weight in lbs by the clients body weight in lbs in order to find your clients percentile ranking
Major disadvantages of a 1 rm test
The chance of injury exist with maximal effort. Clients are more likely to perform the valsalva maneuver. May not be best for beginners
The achievable range of motion at a joint or group of joints without causing injury
