Background Sickle cell disease (SCD) is an inherited hemoglobin disorder marked by chronic hemolytic anemia, recurrent vaso-occlusive pain episodes, and progressive functional impairment. Owing to concerns regarding exercise-induced hypoxia and pain crises, individuals with SCD have traditionally been discouraged from engaging in regular physical activity. Aim This narrative review aims to summarize and critically appraise existing evidence on the effects of physical exercise on oxygenation status, pain crisis frequency, and quality of life in individuals with SCD. Methods A narrative synthesis of clinical, observational, and experimental studies evaluating aerobic and resistance exercise interventions in SCD was conducted. Emphasis was placed on outcomes related to oxygen delivery, pain manifestations, functional capacity, and psychosocial well-being. Results Available evidence suggests that carefully supervised, low-to-moderate intensity exercise is generally safe for individuals with stable SCD. Regular physical activity has been associated with improvements in cardiorespiratory fitness, peripheral oxygen utilization, endothelial function, and fatigue levels, without a proportional increase in vaso-occlusive events. Additionally, exercise participation appears to contribute to enhanced sleep quality, reduced pain perception, and improved psychological health, thereby positively influencing overall quality of life. However, inconsistencies in exercise protocols, small sample sizes, and limited long-term data restrict the strength of current conclusions. Conclusion Physical exercise may serve as a valuable nonpharmacological adjunct in the comprehensive management of SCD when individualized and appropriately monitored. Integrating structured exercise programs within multidisciplinary care may help improve functional outcomes and quality of life.
