“…There are comparisons between different kinds of submaximum tests [3,8] as well as results of submaximum ergometric tests on subjects up to the age of 14 for body-weightstandardized work loads as well as for PWC 170 [5,9]. Up till now, however, it has not been clear how reliably these submaximum tests represent the maximum performance capacity in this fast-growing age group.…”

Thirty-three 10-year-old boys repeatedly performed six symptom-limited, spiroergometric exercise tests according to the vita maxima method over an observation period of 4 years. Submaximum and maximum performance parameters were assessed and their correlation was calculated. The correlation of the heart rate at 1, 2 and 3 watts/kg body weight with the values of maximum performance capacity (wattmax and VO2max) and with the body-weight-related, relative maximum values was statistically significant. The correlation factors for the relative values were about twice as high (r = 0.55) as the absolute values (r = 0.27). The heart rate at 1, 2 and 3 watts/kg therefore was more characteristic of the relative values, which represent the state of training, and less for the absolute performance capacity, which depends to a great extent on body weight. However, the statistically significant correlation factors were too low to estimate reliably the state of training in an individual case. The correlation of physical working capacity at an HR of 170/min (PWC 170) with the maximum ergometric Watt performance was r = 0.80 and therefore appears to be sufficient to estimate the maximum performance capacity in children. This is however only valid for children over the age of 11.

Many factors may intervene with the motor development of children with congenital heart disease (CHD). Children aged 5 to 14 years with various CHD were examined for disturbances of gross and fine motor development using motometric tests and compared with 30 healthy controls. The results of the Körperkoordinationstest für Kinder (KTK) (a body coordination test for children) for gross motor development were significantly lower in patients with uncorrected cyanotic CHD (motor quotient MQ 74.8 +/- 11.7, mean +/- 1 standard deviation, n = 16) and after corrective surgery (MQ 81.2 +/- 16.6, n = 25) than in controls (MQ 102.8 +/- 11.8, n = 30). No relationship between these results and the cardiopulmonary exercise capacity was found. In patients with cyanotic CHD, significant deficits in fine motor development were present before corrective surgery (e.g. Zielpunktiertest [dotting] MQ 87.7 +/- 9.9 vs. 106.5 +/- 10.8), but already two years afterwards the results reached nearly normal values (MQ 97.1 +/- 17.0). In contrast, children with acyanotic CHD demonstrated normal gross and fine motor development. These results indicate that long-standing hypoxemia in infancy must be considered as an important cause of the pronounced motor disturbances. Early neurological evaluation of these children and a specialized motor physiotherapy are recommended.

“…This is in agreement with the work of Lindemann et al (11), who included only data of heart rates greater than 120 bts/min for calculating characteristic parameters for the physical working capacity. Also Mocellin et al (13) proposed using only values obtained during higher work load (1 W/kg body weight) for extrapolation. Because of the high sensitivity of the estimated models' parameters of the regression polynome: b, b, b to outliers in the data points, it does not seem possible to use these parameters as characteristic parameters for the physical working capacity.…”

Experimental findings of the working capacity at a heart rate of 170 bts/min (W170) were compared to predicted values. Statistical tests were applied to examine the suitability and the error of prediction of three different regression models: a linear regression line, a polynomial regression model, and a "break point" regression model, which were compared to the time course of the heart rate during a linearly increasing work load from 0 to 100 W during 10 min. For this study the results of 28 children, 15 and 16 years old, and students of physical education were investigated. When a linear regression line was compared to these data, systematic deviations between measured data and the values estimated by this model were found. When the W170 was predicted using this model from the data collected during the first 10 min of an exercise procedure for the determination of the heart rate index, the physical working capacity was overestimated. The polynomial regression model and the "break point" regression model agreed with the time course of the heart rate without systematic error and allowed an unbiased prediction of the W170 from the first 10 min of the exercise test.
