Abstract (EN): The CARS systematic observation instrument was used in conjunction with heart rate telemetry to measure the physical activity levels of 9 English and 9 Portuguese, 10 year old schoolgirls during primary school playtime. Individual time series correlation coefficients between heart rate and Children's Activity Rating Scale (CARS) activity levels were not significant for Liverpool girls and only significant for one Oporto girl. Results indicate that a vast amount of variance is unaccounted for in both groups of subjects. Moreover, environmental, morphological and physiological factors may affect the relationship between heart rate and the CARS. When used separately, heart rate and CARS methodologies may provide robust patterns of physical activity during playtime. However, results from this study suggest that the efficacy of using a combination of methods is difficult to support, as heart rates and CARS provide contrasting results and may compound the errors in each method.
