Abstract Sickle cell anaemia (SCA) is characterized by reduced red blood cell (RBC) deformability and nitric oxide (NO) bioavailability. The aim of the study was to investigate whether exercise might affect these parameters in SCA. SCA patients and healthy controls (AA) performed an acute submaximal exercise test until subjects reached the first ventilatory threshold (VT 1). https://www.diegojavierfares.com/flash-offer-Finney-Two-Handle-High-Arc-Bathroom-Faucet-p8561-super-offer/
