what is BMI and what is an advantage and disadvantage for the measurement
Body mass index is a measurement that determines if the height and weight ratio in the body is appropriate
- > it is not a direct measure of body fatness, rather it is correlated with certain health risks and is a predictor of health risk at a population level
- > it does not take muscle mass into account, doesn’t tell the individuals whole story (small and ripped or tall and lanky)
- > it is good for population control and estimates but is not necessarily a good measure to use for an individual
why are protocols within strength and fitness testing so important
a strict protocol provides validity and reliability
- > we want our results to be consistent and accurate
- > looking for norms and trends, there are cutoffs for certain values/conditions
RHR
- > resting HR is considered an indicator of cardiorespiratory (aerobic) fitness because it tends to be lower for those who are more aerobically fit (still must consider that RHR is also considered by other factors)
- it is the # of times the heart contracts in a minute
- > low HR at rest: 48
- > high HR at rest 90-100
- > avg RHR 60-80; (73)
- RHR doesn’t really change as you get older; other aging factors may change it tho
resting BP
BP is the force of blood against the walls of the arteries created by the pumping of the heart
- > RBP can also be affected by factors outside of the body; white coat syndrome affects 15-30% of people and it will increase BP
systolic vs diastolic BP
Systolic
- > first number, is the max pressure in the arteries when the heart contracts during a heartbeat
Diastolic
- > second number, the minimum pressure in the arteries when the heart relaxes
Measuring RHR
- Let client sit with feet on floor and arms on chair for 5 minutes; while you wait you can interview the client for any things that may affect the clients RHR)
- Ask permission to touch client and walk them through whats gonna happen
- Find radial pulse with finger or jugular vein pulse
- Once you find it, record BPM for 15sec then multiply by 4
measuring RBP
measured using the brachial artery
1. Get client to sit with back against the chair and arm on table for 5mins. While you wait, ensure the client has abided by the preliminary instructions and does not present with any symptoms that suggest the client should postpone the appointment *ask to touch client
2. Wrap cuff on the bare left upper arm around 2cm above antecubital space (tight enough to slip 2 finger under)
3. rapidly inflate to 70mmHg then slowly increase by 10 until you can no longer hear/feel the heartbeat (using stethoscope or palpating)
4. Slowly release the pressure at approx. 2mmHg/sec
5. Sys. is when you start to hear/feel the heartbeat again and Dias is when it stops
what reading of RHR and RBP are indicators that you should not continue evaluations (from anthropometics data)
RHR > 99BPM
SBP > 160mmHg
DBP >90mmHg
NO EXERCISE UNTIL THEY SEE A DOCTOR
things to consider when measuring weight
- > take shoes off and empty pockets
- > record weight to nearest 0.1kg
- > convert kg to lb by lbx2.2 = kg
Waist circumfrence (WC) and how to take WC
- > evidence suggests that abdominal fatness is a more important determinant of health outcomes
- > high WC = more likely for diabetes and hypertension
- ask if they’re comfortable raising their clothing and you touching them
- find the border of the superior, most lateral border of the iliac crest using palpation
how to score BMI
BMI = wight (kg)/height(mm) ^2
- > consider how thresholds change between ethnicities; i.e. Japanese = lower WC threshold
- > normal range is 18.5 - 24.9 kg/m^2
* if you’re BMI > 30 then you’re obese and if you’re les than the threshold you may not be at risk
- > you must consider the combination of WC and BMI readings
- > BMI may not be perfect for the individual but it’s good for the general public
1 mile walk protocol
Goal: have client walk 1600m/1mi as quickly as possible
1. Explain the purpose (assess aerobic fitness/VO2 max)
2. Secure HR monitor to client
3. Have them to a 3 minute walk at normal pace to warm up. Once completed, check in and explain then send them
4. Client walks the 1600m as quickly as possible (RECORD THEIR TIME)
5. Measure HR immediately after they complete the test and take their blood pressure
grip strength protocol
*measure of isometric strength and a widely used indicator of total body strength; shown to predict functional limitations and disability later in life
1. adjust hand dynamometer to the clients hand (the second joint of the fingers fits snuggly into the handle and takes the weight of the instrument)
2. get client to hold dynamometer in line with the forearm at the level of the thigh
3. squeeze with maximal force, have client exhale while squeezing
4. measure each hand twice, alternating hands and record the maximum of both hands, add together, and find your score at pg 43
vertical jump protocol
*measures peak leg power or the ability to contract leg muscles with speed and force in one explosive motion
1. demonstrate proper technique: elbow width away from wall, bend down (semisquat) and hold for 2 then jump and stick
2. get client to stand against the wall and reach, feet flat on floor
3. allow for 3 trials with a rest period of 10-15 secs, take the best of the 3 jumps
CSEP-CPT limitations
CSEP-CPT are not permitted to use and ECG equipment and conduct aerobic and/or muscular fitness tests that involve reaching >85% of their max, these skills are taught in a separate course
- > this is a liability and safety issue
Get-Active questionnaire
provides guidance as to when physical activity may be appropriate and safe given the client medical history and if they need to refer to their physician
- > if its unclear err on the side of caution; you can work with 1 CONTROLLED chronic condition
- > the form only considers the last 6mo, looks for new uncontrolled issues
- > STILL NEED TO ASK SUSPECTED DIAGNOSED CONDITION AND MEDICATION
reasons to postpone Ax
- > demonstrates difficulty breathing at rest
- > coughs persistently
- > ill/fever
- > lower extremity swelling
- > has clearly ignored the preliminary requirements (only water 2hrs before and no exercise 6hrs before)
- > pregnancy (see pregnancy GAQ)
active recovery procedure
light movement for 3 minutes
- > take HR every minute
- > if client does not feel recovered then take another 2 mins before sitting
- > once sitting measure clients HR and BP at 1 and 3 minutes
- > they are ready to move onto other forms of testing if their reading have below the cutoff values (HR>100, SBP>160, DBP>90)
- > if not then remain seated then test again after 2 mins
when should you not do a Y-Test or a one leg balance test
if there is history of illness/condition that cam prevent the test from being performed safely
One leg balance test protocol
why: balancing on one leg is essential for normal gait and is critical for activities of daily living; good data to predict risk of falls in older populations
Step 1: explain the purpose and protocol to client
Step 2: have client stand barefoot/socks behind or beside a sturdy chair with their arms cross over their chest
Step 3: have client stand on leg of choice and lift opposite fot a few inches off the ground (can redo if they fall within first 3 secs)
Step 4: have client keep eyes on a marker and get them to stand for a mx of 45secs, record to nearest 0.1s
Step 5: repeat on other leg
Step 6: do same tests with eyes closed
Step 7: take the best eye open and eyes close score (leg doesn’t matter) and compare to average
when to terminate one leg balance test
- > uses arms/legs/torso to correct balance
- > uses unsupported leg and touches standing ankle
- > of base foot rotates/moves to maintain balance
allow 2nd attempt if any of these occur in the first 3seconds
purpose of Y-Balance test
it is a modified star excursion test (8points instead of 3)
measuring dynamic balance may be of use in predicting lower extremity injury, identifying dynamic balance deficits, and assessing the effectiveness of lower extremity balance during training programs
Y-Balance test protocol
3 markers must be 135-135-90 deg. apart and test should be done in socks. Heel should be on intersection point
Step 1: Balance on one foot and lightly tap the anterior tape and return to double leg start position
Step 2: Repeat with posteriorlateral tape then posteriomedial tape
- > client is allowed 4 practice trials in each of the three directions of each leg
- > allow for 10s rest between trials
Step 3: Take the mean (Lfoot +Rfoot) score from each direction
y balance test termination criteria
- > unable to maintain single limb stance (heel comes off floor, hands come off hips, excessive trunk movement)
- > makes heavy touches with feet, rests foot on ground instead of tapping, unable to return to starting position under control
