The aim of this study was twofold (1), to examine the prospective relationship of baseline TV viewing with BMI and CRF both at baseline and over a 2-year period, and (2) to examine the prospective relationship of baseline TV viewing and changes (Δ) on BMI and CRF over a 2-year period. Data were collected in a sample of 135 (64 girls) rural children ages 7 yr-old from elementary schools in Fundao, Portugal. Obesity status was obtained by the age-sex specific BMI cut points and CRF by a 9 min run test. TV viewing was also analyzed and children were assigned as one of two groups: the low TV watching (LTV), and high TV watching (HTV), users based upon them reported to spend less or more than 2 h/day watching TV, respectively. Logistic regression showed that those who were assigned to HTV group were 2.4 times (OR = 2.48; p = .04) more likely to be classified as unfit at time 1. Further the data showed that the LTV were more likely (OR = 0.36; p = .02) to be classified in high ΔCRF change over time. The findings of this study suggest that there was a significant inverse association between times spent watching TV and CRF but not BMI over a 2-yr period.

Using the Oxygen Uptake Efficiency Slope as an Indicator of Cardiorespiratory Fitness in the Obese Pediatric Population

The aim of the current study was to investigate the relationship between the Oxygen Uptake Efficiency Slope (OUES) and traditional measures of cardiorespiratory function in an overweight/obese pediatric sample. Maximal treadmill exercise testing with indirect calorimetry was completed on 56 obese children aged 7–18 years. Maximal OUES, submaximal OUES, VO2peak, VEpeak, and ventilatory threshold (VT) were determined. In line with comparable research in healthy-weight samples, maximal and submaximal OUES were both correlated with VO2peak, VEpeak, and VT (r2= 0.44−0.91) in the obese pediatric sample. Correlations were also found with anthropometric variables, including height (cm), body surface area (m2), body mass (kg), and fat free mass (kg). In comparing our data to a published sample of healthy weight children, maximal and submaximal exercise OUES were both higher in our obese sample. However, when we adjusted for any of body mass (kg), BSA (m2), or FFM (kg) the obese children were found to be less efficient. The results of this study suggest the use of OUES to be an appropriate measure of efficiency of ventilation and cardiorespiratory function in obese children, while also showing that our sample of obese children were less efficient on a per kilogram basis when compared with their healthy weight peers.

This article has been retracted as of May 6, 2022, because concerns were received from a reader that the article contains inaccurate data. An independent review of the study data was conducted in coordination with the authors, and it was determined that the originally published data are inaccurate and a complete set of corrected data is not available as the authors claim a portion of the original measurements have been lost. As a result of these findings, the article is retracted.

Physical fitness is one of the strongest predictors of health throughout the lifespan ( Ortega et al., 2018 ; Raghuveer et al., 2020 ). Two main components of fitness with documented benefits on health are cardiorespiratory fitness (CRF) and muscular fitness ( Fraser et al., 2021 ; Ortega et
