Which has a SEE of В±5 mlsO 2/kg/min would mean that the actual VO 2 max could be between 50 and 60 mlsO 2/kg/min. For example: a predictive result of 55 mlsO 2/kg/min from an aerobic capacity test The measurement units of the predicted variable (e.g. Errors of estimate are usually expressed in However, indirectДЄssessments of aerobic capacity are predictive and therefore are subject to error known as the standard error of estimate (SEE). on a fire station and are often suitable for mass testing (e.g. More cost effective, can be performed вЂin the fieldвЂ™ i.e. Indirect methods of assessing aerobic capacity have several advantages over maximal testing: they require much less sophisticated equipment and technical support, making them Rates have been proposed as problematic due to a standard deviation of в‘1 beats/min and therefore should not be used in isolation. However, the use of age-adjusted estimates of maximal heart Increase in heart rate to reach age-related theoretical maximum or a respiratory exchange ratio (RER) of в‰Ґ1.15. Considerable encouragement by the test supervisor may be required to urge the subject to maximal effort.Дifficulties in determining the attainment of maximal effort has led to the use of вЂsecondary criteriaвЂ™ as additional determinants of maximal effort these are typically: an This could result in the test being terminated before VO2max has been attained thus under stating the true Motivational strength to push themselves to a true maximum effort.

In some cases subjects may not have sufficient psychological or Termination will usually be determined by the subject and occur at a point when they feel unable to continue. Another factor for consideration by the test administrator is the criteria for termination of the test. Measurement of aerobic capacity is regarded as the most accurate, careful attention should be taken when fitting the face mask as any leakage between the face mask and faceД¬an lead to inaccurate results. The equipment is usually calibrated before each test and requires regular servicing.

by 3% gradient per stage).Д¬alibration of the measuring equipment is essential for maintaining accuracy. Load applied at subsequent increments should increase uniformly (e.g. This allows the heart rate to plateau before commencement of the next increment. The optimum duration of each increment of the protocol ranges from 2-3 minutes. Protocols used in conjunction with gas analysis should generally aim to bring the subject to the desired intensity within an 8-12 minutes time Watts / speed / gradient), size and duration of increments and overall duration of the test requires some care and skill on the part This is connected, via a low resistance breathing valve to either Douglas bags for gas collection and later analysis or directly toДЄn on-line gas analyser (such as a Covox or Cosmed system) providing breath-by-breath data.Дirect measurement of aerobic capacity using gas analysis predominantly utilise incremental ramp protocols carried out on either a treadmill or static cycle. Direct measurement requires the subject to wear a mask covering the mouthДЄnd nose or use a mouthpiece and nose clip. Should be familiar with the issues raised in order that the most appropriate test is adopted and the correct test procedures are followed.Дirect measurement is considered the вЂgold standardвЂ™ in the assessment of cardiorespiratory fitness. Whichever test(s) are used to deliver a routine fitness-testing schedule, those responsible for implementing fitness testing The strengths and weaknesses of these tests. The report also described each test protocol and discusses Many of these issues are also discussed in this section. Most appropriate fitness test for your serviceвЂ™s situation. Information remains relevant to current fitness testing practices and should be considered a resource that can assist in understanding these issues and to help determine the Tests, which include areas such as the direct and indirect determination of VO 2 max and the pros and cons of sub-maximal and maximal exercise testing. The report discusses the issues surrounding the various types of cardio-respiratory fitness In 2009 the FireFit Steering Group published a set of guidelines relating to a collection of fitness tests that could be considered appropriate for measuringД¬ardio-respiratory fitness (VO 2 max) in firefighters.
