Term
Forced Vital Capacity
Definition

Forced Vital Capacity is the total amount of air moved in one breath from full inspiration to maximum expiration.


FVC = TV + IRV + ERV


it ranges between 4-5 L in healthy young men and 3-4L in healthy young women.


The volume of air that can be forcibly and maximally exhaled out of the lungs until no more can be expired after teh patient has taken in teh deepenst breath possible

Term
Tidal Volume
Definition

Tidal Volume, describes air volume moved during either the inspiratory or expiratory phase of each breathing cycle. 

Term

 Inspiratory Reserve Volume (IRV)

Definition
 Inspiratory Reserve Volume, the additional volume to the TV inspired on a deep breath
Term

ERV = Expiratory Reserve Volume (ERV)

Definition
Expiratory Reserve Volume, after IRV measurement the subject reestablishes the normal breathing pattern and on one exhale forces as much air out of the lungs as possible, this additional volume exhale is the ERV.
Term

FEV1

Definition

Forced Expiratory Volume in one second, healthy individuals normally expel 85% of the VC in 1 second


Definition: The volume of air that an be forcibly exhaled from the lungs in th first second of a forced expiratory maneuver; FEV1 is expressed as liters

Term

Maximum Voluntary Ventilation (MVV) 

Definition

Maximum Voluntary Ventilation (MVV) is the maximal volume of air that can be inhaled and exhaled from the lungs over a sustained time. Typically MVV tests will last 12 – 15 seconds.


The values are then used to calculate the rate of airflow per minute (L min-1).


Estimates breathing reserve during maximal exercise


MVV is a measure of the overall capacity of the respiratory system to move air. The measure depends on the strength of the respiratory muscles, compliance of the lung-thorax system

and the resistance of the airways.

Term
MVV Testing Procedure Steps
Definition

Procedures

1. Participant attaches the nose clip and breathes normally for 2 to 3 seconds.

2. The technician instructs the participant to inhale and exhale deeply (30 – 50% of VC) as rapidly as

possible (> 100 breaths min-1) for 12 – 15 seconds.

3. The participant should be specifically told to concentrate on inhaling and exhaling as fast as

possible and to keep going for the full duration of the test. The entire MVV test may last for 20

seconds, but the MVV is actually only recorded for 12 seconds.

4. At the conclusion of the test, the calculated MVV is displayed in L min-1.

5. Repeat the test and record the highest MVV value obtained.

In some cases, it’s not possible or desirable to measure MVV. Instead, MVV can be estimated from

FEV1 using the following equation:

Estimated MVV (L min-1) = (FEV1 * 37.5) + 15.8

(would need 3 of the following criteria)

Definition

-Subject exhaustion: Rate or Perceived Exhaustion (RPE)> 17

-VO2 Plateau

-Heart Rate Maximum greater or equal to predicted HR max (220-age +/- 10 bpm) or HR plateau

-Respiratory Exchange Ratio (RER) > 1.15 (RER=VCO2/VO2)

-Lactate > 8mmol-L--1

Term

Term
VO2 Plateau vs. Peak
Definition

Peak is when there is no plateau, can be where there is a maximum test that is not finished.

Term
Muscular Fitness
Definition

Muscular fitness is the term used to describe overall ability on the continuum of muscular performance where strength and endurance represent the polar ends of this continuum.


From an assessment perspective, strength is the measurement of the maximal force capability of the muscle.

endurance is the measurement of the ability to continue performing a contraction at a submaximal level.

Term
Push-Up Test Criteria (meaures muscular endurance)
Definition

 Push-up Test Procedures for Measurement of Muscular Endurance 

 

The test is administered with male subjects starting in the standard “down” position.  Hands 

should be pointing forward and under the shoulder with the back straight using the toes as the 

pivot point.  Female subjects start in the modified “knee push-up” position with legs together, 

lower legs in contact with the mat with ankles plantar flexed, back straight, hands shoulder 

width apart, head up and using the knees as the pivot point.  

 

The subject must raise the body by straightening the elbows and return to the “down” position, 

until the chin touches the mat.  The person administering the test can also place their fist on 

the mat as a marker.  The stomach should not touch the mat.  

 

For both men and women, the subject’s back must be straight at all times and the subject 

must push up to a straight arm position.  

 

The maximal number of push-ups performed consecutively without rest is counted as the 

score.  

 

The test is stopped when the client strains forcibly or is unable to maintain the appropriate 

technique within two repetitions.  

 

 
Term
Curl-up (Crunch) Test (measures muscular endurance)
Definition

•The individual assumes a supine position on a mat with the knees at 90 degrees, arms at their side, palms facing down with the middle finders touch a piece of tape. A second piece of

masking tape is placed 10 cm apart. Shoes remain on during the test.

•A metronome is set to 50 beats min -1 and the individual does slow, controlled curl-ups lifting the shoulder blades off the mat (trunk makes a 30 degree angle with the mat) in time with the

metronome at a rate of 25 per minute. The test is done for 1-minute and the low back should be flattened before curling up.

•The individual performs as many curl-ups as possible without pausing to a maximum of 25.

Term
Static Hangrip Strength (Measures Muscular Strength)
Definition

•Have the client stand for the test. Usually, this test is performed with each hand. The norms provided use a combined score for the right and left hands. The test can also be performed

with only the dominant hand.

•Adjust the grip bar so that the second joint of the finders will be bent to grip the handle of the dynamometer.

•Have the client hold the handgrip dynamometer parallel to the side of the body. The elbow should be flexed at 90 degrees. Make sure that the dynamometer is set to zero.

•The client should then squeeze the handgrip dynamometer as hard as possible without holding the breath (to avoid the Valsalva maneuver).

•The client may choose to extend the elbow, however, other body movements should be avoided.

•Record the handgrip strength in kilograms. Repeat this procedure using the opposite hand.

•Repeat the test two more times with each hand. Take the highest of the three readings for each hand and add these two values together 

Term
Anaerobic Power Definition
Definition

The immediate and short-term energy systems predominantly power all-out exercise for up to 2-minutes. Both systems operate anaerobically. When movement begins, intramuscular highenergy

phosphates ATP and PCr provide immediate energy to power muscle action. Following the first few seconds of movement, glycolytic pathways generate an increasingly greater percentage of

energy for ATP resynthesis.

Term
Vertical Jump Test Criteria
Definition

  • Stand with feet together with dominant side next to the wall With dominant arm, reach as high as you can while keeping your feet flat on the floor.
  • Chalk fingers on dominant side.
  • Place palm flat against wall and measure the tip of the finger highest to the wall.
  • Move feet to a comfortable jumping “take-off”position.
  • Dig legs and hips and swing arms in preparation to the “push-off”for the jump.
  • Jump! And while in the air reaching as high as possible swat the wall, leaving a chalk mark.
  • Land with knees bent to absorb force.
  • Repeat 3 times with ~20 to 30 seconds recovery between each trial.
  • Record distance jumped for each trial to the nearest .5 inch.
  • Score is the best of 3 trials.

Term
Calculating Mean Power after Vertical Jump Test
Definition

To calculate mean power:

P (kgm/sec) = 2.21 x Bodyweight (kg) x the square root of (jump height –standing height)


Convert into Watss where 1 Watt=6.1 kgm/min; 1KM=0.1635

To Calculate relative power: Relative P (watts/kg)=Watts/Bodyweight (kg)

Calculations:

1. Resistance (Force) = Bodyweight (kg) x .075 = ________kp

Convert to Newtons *1 kp = 9.8 N

2. Peak Power = Force (N) x Max # Revolutions in 5 seconds x 6 meters/rev

5 seconds = _____________Watts (Nm s -1)

3. Relative Peak Power = Peak Power (Watts)/Weight (kg) = _____________ W kg -1

4. Mean Power (Anaerobic Capacity) = Force (N) x Total Revolutions
