and exercise testing strategies to predict performance and improve training concepts and competition results. Values that are classically used to predict running performance include maximal oxygen uptake (VO 2 max), percentage of VO 2 max, ventilatory and lactate thresholds, and running economy. 1

To investigate a new power-to-body-mass (BM) ratio 3-min all-out cycling test (3MT%BM) for determining critical power (CP) and finite work capacity above CP (W ′).
The gas-exchange threshold (GET), maximal oxygen uptake (VO2max), and power output evoking VO2max (W peak) and GET (W GET) for cycle ergometry were determined in 12 participants. CP and W′ were determined using the original “linear factor” 3MT (3MTrpm^2) and compared with CP and W′ derived from a procedure, the 3MT%BM, using the subject’s body mass and self-reported physical activity rating (PA-R), with values derived from linear regression of the work–time model and power–inverse-time model (1/time) data from 3 separate exhaustive squarewave bouts.
The VO2max, VO2GET, W peak, and W GET values estimated from PA-R and a non-exercise-regression equation did not differ (P > .05) from actual measurements. Estimates of CP derived from the 3MT%BM (235 ± 56 W), 3MTrpm^2 (234 ± 62 W), work–time (231 ± 57 W), and 1/time models (230 ± 57 W) did not differ (F = 0.46, P = .72). Similarly, estimates of W′ between all methods did not differ (F = 3.58, P = .07). There were strong comparisons of the 3MT%BM to 1/time and work–time models with the average correlation, standard error of the measurement, and CV% for critical power being .96, 8.74 W, and 4.64%, respectively.
The 3MT%BM is a valid, single-visit protocol for determining CP and W′.

Exercise testing has become an important method for evaluation of pediatric patients with known or suspected arrhythmias. It has proven useful in patients with exercise-induced symptoms, patients with congenital heart disease, and patients with pacemakers. Exercise has predictable effects on the normal electrocardiogram. Exercise can also bring out abnormalities in cardiac rhythm that may not be present at rest. The results of exercise testing can provide information that directs further therapy or evaluation. Exercise testing also helps to evaluate the efficacy of antiarrhythmic therapy in some patients.

The gold standard measurement assessment of CRF is the laboratory-based cardiopulmonary exercise test (CPET), which requires the measurement of peak oxygen consumption (VO 2 peak) typically during treadmill or cycling exercise. In particular, CPET has been increasingly utilized in the

Because it is not known how often and how uniformly exercise testing is used to “unmask” recurrent or persistent coarctation of the aorta, this study was designed to determine (a) the frequency with which exercise testing is used by the clinician to evaluate patients after coarctation repair, and (b) the hemodynamic measures obtained with exercise that are considered to be indicative of significant persistent or recurrent coarctation. Questionnaires were sent to 80 randomly selected pediatric cardiologists; 49 were returned completed. About half of the respondents performed exercise testing (ET) on all of their patients after coarctation repair and 75 % tested at least half. Those who supervised an exercise laboratory used ET for a significantly greater number of their patients. In descending order, rest arm-leg gradient (ALG), maximal exercise systolic blood pressure (MXBP), and postexercise ALG were considered the most important indicators of significant recoarctation. The majority of respondents made decisions based on data from the ET that were consistent with published guidelines.
