“…Both isometric strength tests (e.g., Blakley et al, 1994) and isotonic 1‐RM strength tests, recommended by The American Society of Exercise Physiologists (Brown & Weir, 2001), provide highly reliable measurements in units that are directly comparable across studies. Similarly, field measures of aerobic endurance, such as the step‐test (e.g., Cotten, 1971; Davis & Wilmore, 1990) or 1.5‐mile run (e.g., Larsen et al, 2002) are readily converted into estimates of Vo 2 max in liters per minute or relative Vo 2 max in l/[minute kg]. Correlations of S/E measures with the simulation test scores used to hire the new employees can provide insight about the S/E demands of the simulation and can be used in conjunction with the applicant pool simulation SD to provide range restriction estimates of S/E in the selected group (Sackett & Yang, 2000).…”

Milwaukee Fire Department (Ret.), Milwaukee TOMISLOV MATIC Milwaukee Fire Department (Ret.), MilwaukeeRecruits from 9 consecutive fire academy classes were assessed on a battery of strength and endurance measures at Weeks 1, 7, and 14 of training. Regression analyses using Week 1 measures indicated that strength variables were the primary predictors of performance on physically demanding firefighting tasks assessed at the completion of training. Incremental validity was obtained with the addition of aerobic capacity, which produced more accurate performance distinctions among recruits with high strength levels. Results showed predictive validity and linearity throughout the upper range of strength and endurance levels, but evidence of an increased drop-off in performance for recruits with strength levels below the male 25th percentile. Structural equation modeling, a more powerful and comprehensive approach to validation than traditional regression, provided strong support for the construct validity of general strength and endurance as predictors of firefighter performance on physically demanding fire suppression and rescue tasks.Physical ability selection tests for municipal firefighters rapidly shifted away from the use of measures of strength and endurance based on criterion or construct validation models, following an initially successful legal challenge to this approach (Berkman v. the City of New York, 1982). The federal trial court ruled that although the test was professionally developed, the research on which it was based measured general human ability rather than firefighting skills in particular. Assessments of muscular strength and general fitness were largely replaced by tests based on a content validity strategy using simulated fire suppression and rescue tasks. This change was probably due in part to the perception that such tasks would be more readily accepted as "job related" by courts than field tests derived fromCorrespondence and requests for reprints should be addressed to

“…The Balke test involves walking at a progressively increasing work rate, and is scored on the basis of time to achieve a heart rate of 180 b/min. The multi-stage step tests devised by Kurucz et al (1969), Cotten (1971), and Witten (1973) are all based on the same scoring principle as the Balke test, i.e. the time to achieve a prescribed heart rate.…”

Step tests of cardiorespiratory fitness suitable for mass testing.

Step tests have been widely used to assess cardiorespiratory fitness. Work rate is determined by step height and step frequency, whereas the total amount of work done depends upon the number and duration of work periods. In all step tests which are suitable for mass testing, performance is based on heart rate during recovery. A review of the literature strongly suggests that step tests can give reliable and valid measures of cardiorespiratory fitness provided that (a) the subjects have received adequate instruction and practice in taking the test prior to the criterion test performance, and (b) the work load is above a certain threshold.

“…The factors which govern the rate of decrease of heart rate during recovery are not well investigated. Further it is reported by many investigators that the magnitude of work done determines the rate of decrease of heart rate during recovery (Royce 1969, Cotten 1971, McArdle et al 1969, Ryhming 1953and Shephard 1966. In our study it is shown that the recovery heart at the beginning of recovery is strongly influenced by the heart rate during work and V02 max.…”

We have studied 73, top level Indian sportsmen for V02 max and heart rates during work and recovery. High negative values of 'r' between V02 max and heart rate during work and recovery have been observed. Absolute V02 max, V02 max/kg body wt/min and V02 max/kg lean body mass/min are found to play an important role in influencing recovery of heart rate, more so in the initial phases. A similar trend has been observed while studying the influence of work heart rate on the recovery of heart rate after a standard exercise. Regression equations for the prediction of V02 max from recovery pulse scores, have been worked out for Indian sportsmen.
