Introduction: Field tests are commonly used as complements of cardiopulmonary exercise test (CPET) to evaluate the functional exercise capacity. The aims of this study were to validate the one-minute sit-to-stand test (STST) in congenital heart disease (CHD) children and to evaluate the possibility of predicting the peakVO 2 using the STST in this paediatric population., Methods: Children (8- to 18-year-old) followed for a CHD and performing CPET were recruited prospectively. Concomitantly, they performed STST. The heart rate (HR), oxygen saturation (SpO 2 ), muscular fatigue and dyspnoea were recorded before (t0), immediately after (t1) and 1min after the end of the STST (t2)., Results: We observed a poor but significant correlation between the STST and the peakVO 2 (r=0.306; p=0.013). A significant difference between girls and boys were observed for peakVO 2 (p<0.001), HR t0 (p=0.030), HR t1 (p=0.002) and HR t2 (p<0.001). The proposed model of prediction, including the number of STST, weight, height and age explains 37% of the predicted peakVO 2 variance., Conclusion: The STST can provide relevant data on physical capacity in children with CHD. When CPET cannot be performed, we therefore propose an alternative equation using the STST as a surrogate of peakVO 2 in CHD children., (Copyright © 2024 SEPAR. Published by Elsevier España, S.L.U.

Introduction: Bronchopulmonary dysplasia (BPD) is the most common complication of extreme preterm delivery, and is associated with reduced exercise tolerance and exercise capacity. The aim of this study was to assess the effects of a physical activity programme on exercise tolerance, exercise capacity, flexibility, and lung function in prematurely born children with BPD., Methods: This was a randomized controlled trial. Preterm children with BPD (4-6 years) were randomized to intervention (IG) and control (CG) groups. The CG did not participate in any physical activity during the study period. The IG performed a 4-week exercise programme based on aerobic interval and resistance training. Outcomes were based on the 6-minute walk test (6MWT), incremental shuttle walk test (ISWT), modified sit and reach test (MSRT) and spirometry results., Results: Twenty individuals were recruited. In the IG (n=10), statistical and clinical improvement was observed in the 6MWT (316.3±31.4m vs 376.2±39.5m; P=.002). Significant improvements were also seen in the IG in the ISWT (248.0±45.2m vs 465.3±58.2m; P=.013), MSRT (14.5±7.7cm vs 22.8±6.9cm; P=.003), and FEV 1 (102%±16% pred vs 104%±17% pred; P=.004). No significant differences between pre- and post-intervention were observed in the CG for all outcomes (n=10)., Conclusion: This 4-week programme resulted in statistical and clinical improvements in exercise tolerance, exercise capacity and flexibility in preterm children with BPD., (Copyright © 2018 SEPAR.
